Built for Fun at the Wheel
Audi is taking the wraps off a new sports car – the Audi TTS, the top of the TT model line. It will be coming to dealer showrooms in the early summer. Under its hood lies a two-liter TFSI high-performance engine delivering a mighty 272 bhp. This intense power propels the TTS Coupe to 60 mph from a standstill in just 5 seconds and on to a governor-limited top speed of 155. The Audi TTS is available as both a 2 + 2-seater coupe and as a roadster.

Designed to appeal to a young and dynamic clientele, the TTS represents the Audi brand's Vorsprung durch Technik (“advancement through technology”) in its very latest form. The TFSI engine in the TTS takes the two Audi technologies of gasoline direct injection and turbocharging and blends them to form a perfect partnership. Aside from its output of 272 bhp, it is its peak torque of
258.15 lb-ft, which is constantly on tap between 2,500 and 5,000 rpm, that makes the compact and lightweight four-cylinder unit so impressive.

Compared to the engine it was derived from, the two-liter power unit has been reengineered and strengthened in a number of key areas to ready it for operation in the TTS. Thanks to its excellent efficiency, the sporty-sounding TFSI has an average fuel consumption of just 29.375 mpg in the Coupe when partnered by the six-speed manual transmission, while the figure for the roadster averages 28.659 mpg. These figures are improved by 0.372 and 0.716 mpg, respectively, if the optional S tronic dual-clutch transmission is fitted.

S tronic, which deploys two clutches, is capable of performing extremely quick gear shifts at high engine loads and rev speeds; consequently, the time taken to sprint from zero to 60 mph is cut by a further two-tenths of a second in both the Coupe and Roadster. Loss-free transfer of power to the road is the task of the standard quattro permanent all-wheel drive that enables the TTS to accelerate quicker and with greater stability than its rivals. At the heart of this system is a hydraulic multi-plate clutch that works faster than ever thanks to a new pressure reservoir.

The TTS rolls off the production line equipped with yet another high-tech module – the Audi magnetic ride adaptive damping system. This gives the driver the choice of two characteristic settings: “Standard” mode is designed for a well-balanced, comfortable ride, whereas in the “Sport” setting the TTS harnesses all of the potential of its sports suspension – which lowers the body by 0.39 in. – to deliver uncompromisingly dynamic handling. Its front suspension is mainly made of aluminum, while the efficient technology of the precision electromechanical steering also helps to improve fuel consumption considerably. The sports car is safely brought to a standstill by the high-performance braking system with its 17-inch discs.

Yet another factor in the supreme performance of the TTS is the hybrid construction of its body. Steel is used at the rear end, while the front and center sections of the body are built from lightweight aluminum. ASF (Audi Space Frame) technology optimizes axle load distribution and reduces the overall weight. The manual Coupe weighs just 3,075.45 lbs, which equates to a power-to-weight ratio of 11.24 lbs/bhp.

Powerful Looks

The Audi TTS instantly stands out as the dynamic flagship of the TT model line. The standard 18-inch aluminum wheels are a highlight of the exterior design, as are the headlights, comprising newly designed bi-xenon units with LED daytime running lights. Inside, passengers are welcomed by deep-set sports seats trimmed in a mixture of leather and Alcantara, with Silk Nappa leather seat upholstery in four different color combinations available as an option. The gray instrument panel as well as the multifunctional steering wheel add further styling touches.

The Interior

Awaiting the passengers inside are deep-set sports seats featuring seat heating and height adjustment. They come as standard with leather/Alcantara seat covers in either black or black and silver, plus silver-colored contrast stitching. The sports seats are optionally available in Silk Nappa leather upholstery. There is also the option of the Impulse leather package, comprising black trim with silver stitching in the Coupe or chennai brown trim with espresso-colored contrast stitching in the Roadster.

The cockpit in the TTS is molded around the driver like a sleek-fitting suit. Its clean-cut, sporty design and uncompromising quality of construction is another Audi trademark. Instruments with a gray background and white needles, metal pedals, aluminum trim panels, plus a multifunctional leather sports steering wheel with a rim that’s flattened at the bottom add further styling touches.

THE FIRST-EVER BMW X6 SPORTS ACTIVITY COUPE
BMW will once again introduce a ground-breaking idea to the world and the creation of a new segment with the debut of its all-new X6 Sports Activity Coupe at the 2008 Detroit Auto Show in January. The all-new vehicle redefines the very notion of a coupe — with five doors and four sculpted seats, a higher ride and loads of cargo space. It defies coupe conventions in one jaw-dropping look, combining coupe agility and SAV versatility, taking the coupe to a higher level. As the world's first Sports Activity Coupe, the BMW X6 will be available in two engine variants: the xDrive50i (4.4 V8 engine, 400 hp, 450lb.-ft torque) and the xDrive35i (3.0 inline six-cylinder engine, 300 hp, 300 lb.-ft torque), both with Twin Turbo and direct injection. The BMW X6 offers unique features and performance ability in a combination unmatched by any other vehicle. The new BMW X6's design combines the sporting elegance of a large BMW Coupe with the powerful presence of a BMW X model.

The BMW X6 comes as standard with BMW's intelligent xDrive all-wheel-drive technology with electronic control for variable distribution of drive power between the front and rear axles, consistently adjusted to driving conditions at all times and in all situations.

Featured for the first time as standard in the BMW X6, Dynamic Performance Control likewise ensures variable distribution of drive forces between the two rear wheels. Dynamic Performance Control incorporates an advanced computer control and an innovative rear differential incorporating two planetary gearsets and two clutch packs that enables the system to multiply torque on an individual rear wheel. The result is that Dynamic Performance Control can help steer the vehicle by directing torque to either of the rear wheels. Unique the world over, this cutting-edge technology is effective whether the driver is accelerating or decelerating and significantly enhances steering precision and, as a result, the agility of the vehicle at any speed. In fast corners with abrupt steering maneuvers or with the driver suddenly releasing the gas pedal, Dynamic Performance Control serves to improve the stability of the entire vehicle, thus allowing the driver to safely enter and enjoy new dimensions of driving dynamics. Finally, on slippery or uneven surfaces, Dynamic Performance Control provides the further advantage of even safer and more stable traction.

The new V8 engine with Twin Turbo technology and direct gasoline injection, is likewise making its world debut in the BMW X6. Displacing 4.4 liters, this eight-cylinder with maximum engine output of 400 hp and peak torque of 450 lb-ft available over an unusually large range of engine speed from 1,800-4,500 rpm, is the most powerful engine ever seen in a BMW X Model.

The new eight-cylinder is indeed truly impressive not only through its outstanding thrust and pulling force, but also through its compact dimensions. For this is the first eight-cylinder gasoline engine in the world to feature its turbocharger in the V-section between the two rows of cylinders.

Hence, the BMW Sports Activity Coupe is an absolutely exceptional vehicle also beyond the direct range of BMW X Model competitors, ensuring unparalleled performance in all situations, regardless of road and surface conditions.

Unique design: dynamic line, powerful presence.

In its design, the BMW X6 definitely offers all the DNA of a genuine BMW X Model, interpreted however, in a brand-new, extremely sporting style. Indeed, the design language of this new model is the authentic visualization of the outstanding driving characteristics offered by the BMW X6, mainly through intelligent BMW xDrive all-wheel-drive technology and Dynamic Performance Control.

Various design features typical of BMW also stand out in the car's details, ranging from the BMW kidney grille to the dual round headlights optically "cut off" at the top and the powerful contour line along the side, all the way to the horizontal lines at the rear emphasizing the sheer width of the vehicle.

Front end with clear and dynamic orientation to the road.

Just one look at the front end of BMW's new Sports Activity Coupe demonstrates the powerful presence of this unique vehicle. Due to the greater share of surfaces finished in body color, the front end looks lower and even more dynamic, clearly emphasizing the powerful orientation of the BMW X6 to the road. This DNA so typical of BMW is also demonstrated in the design of the hood and in the vertically positioned BMW kidney grille, with fins finished in a sophisticated titanium color on the xDrive50i and in black on the xDrive35i.

Large air intakes are positioned far to the outside for more than just meeting the cooling requirements of the powerful engines. Rather, interacting with the side panels extending far to the inside over the headlights, the air scoops provide clear orientation towards the wheels, emphasizing the powerful stance of the vehicle on the road.

The headlights themselves merge in a dynamic sweeping line into the side panels, the surface of the engine compartment lid is divided by striking lines tapering out towards the BMW kidney grille like the borderlines of the engine compartment lid at the sides.

Side view: dynamic roofline, muscular surfaces.

The unique proportions of the new BMW X6 stand out particularly clearly from the side. For example, the short body overhang at the front emphasizes the dynamic look of the vehicle, while the roof line tapering out gently towards the rear and the long body overhang on the rear section, add to the stretched silhouette of a genuine coupe.

At the rear, the side window frame features the "counter-swing" at the bottom of the D-pillar, so well-known as the "Hofmeister kink" and chrome surrounds on the windows featured as standard distinguish the BMW X6 xDrive50i from the xDrive35i.

The high waistline and powerfully contoured wheel arches both front and rear, moving the visual center of gravity to the middle of the vehicle and thus bearing testimony to all-wheel drive, are further significant features of the DNA of a BMW X Model.

The side panel is split by two lines with striking contours, moving slowly towards one another at the front end of the vehicle to create a wedge-like impression symbolising the forward-pushing, powerful character of the BMW X6. While the lines at the side highlight the supreme elegance of the car, the special design of the surface gives the BMW X6 a particularly powerful look from this perspective. Striking interaction of the concave and convex surfaces emphasize the muscular look of the vehicle, providing the BMW X6 with an excellent balance of visual power and stylish presence.

Strong shoulders and a powerful stance from the rear.

Likewise, the rear end of the BMW X6 offers a thrilling combination of elegance, sportiness and robustness in full harmony with one another. The muscular bumper and protection cover on the underfloor; the striking light edge along the lower section of the bumper, highlighting the ride height of the BMW X6; and the vehicle proportions that are so typical of a coupe, are all examples of classic design elements that stand out clearly and convincingly in the particular style and looks of a BMW X Model.

The entire rear end is subdivided by horizontal lines giving the rear end a wider look and emphasizing the powerful stance and road-holding of the entire vehicle. The greenhouse with its strikingly low rear window, in turn, tapers out smoothly towards the rear, with the rear lid featuring a distinct air flow lip, further proof that this unique new vehicle is a genuine coupe in both its looks and style.

Even the special design of the rear light clusters takes the unique character of the BMW X6 into account, the L-shape so typical of a BMW X Model being re-interpreted and now boasting a particularly dynamic sweep from one side to the other. Extending far into the side panels, the rear-light clusters bring out and accentuate the entire width of the vehicle also through its night design.

Sportiness and luxury within the interior.

To the very last detail, the interior of the BMW X6 offers a unique synthesis of luxury, sporting dynamics, and powerful style. Tense surfaces blending into one another symbolize the active character of BMW's Sports Activity Coupe, sporting features such as kneepads on both sides of the center console, paddles on the sports steering wheel featured as standard, and the fine scale on the circular instruments creating an excitingly different driving experience in the new BMW X6 both on the road and off the beaten track.

Like all BMW X Models, the new Sports Activity Coupe offers the occupants of all four seats an elevated, commanding seating position. In particular, this gives the driver a clear feeling of being perfectly in control of his BMW X6 in all situations. In conjunction with the cockpit simply begging the driver to drive his vehicle in an active style, this creates an innovative impression of genuine, all-out sportiness.

A further point distinguishing the world's first Sports Activity Coupe from the other BMW X Models is the sporting design of the individual rear seats separated from one another through the center console, the high-rising side supports, and the integrated headrests on all four seats.

The BMW X6 is the only car in the complete segment of BMW X Models to feature a sports steering wheel with gearshift paddles as standard, which enable the driver to shift gears manually on the six-speed automatic transmission for enhanced smoothness and response at all times. Furthermore, multifunction buttons on the steering wheel operate the telephone and audio systems quickly, smoothly and without the slightest distraction, while two additional buttons may be programmed individually according to the driver's personal preferences.

The instrument panel is dominated by dual round instruments with fine scales reminiscent of motorsport as clear visual reference to the sporting character of the BMW X6. The galvanized trim rings on the instrument panel clearly accentuate the exclusive character of the vehicle's interior, with the same high-quality metal shimmer being boasted on the rotary knobs, the door openers, on the gearshift lever knob, and on the brackets within the air vents.

The new kneepads on the center console stand out clearly as a particularly sporting feature offering the driver and front passenger additional stability in maneuvers in city traffic and when driving off-road under tough conditions.

Visibly and tangibly sophisticated, premium quality surfaces make the interior of the BMW X6 a genuine experience to feel and behold at all times. Through their special quality designed for lasting strength and resistance, the interior surfaces also emphasize the superior robustness of the vehicle committed to off-road use whenever required.

Lots of space, lots of customization options.

Wide opening rear doors facilitate access to the two rear seats, while head-room in the rear is unusually generous for a coupe-seat height of 37.2 inches guarantees supreme comfort and convenience, even for tall passengers.

A wide range of materials and colors highlighting the sporting character of the BMW X6 adds to the individual style and personality of this unique vehicle. The exterior paintwork, for example, comes in a choice of no less than ten exterior colors, eleven leather options and three trim options ensure a wide range of individual style and choice.

Trim in ash grain has been created especially for BMW's Sports Activity Coupe. And while the wood variant exudes a particular touch of discreet exclusivity, the sweeping polish on the aluminum version shows a clear and distinct reference to motorsport.

The passenger and luggage compartment on the BMW X6 are distinctly separated from one another in the usual style one would expect of a fully-fledged coupe. Offering almost 25.6 cu ft of storage space, the luggage compartment behind the rear seats of the BMW X6 is far larger than in a conventional coupe, providing enough space to store four full-size golf bags in the luggage compartment-even with four people riding in the vehicle.

BMW's new Sports Activity Coupe also boasts a firm, folding cover on top of the luggage compartment that can be folded at stowed beneath the floor for convenient transportation of bulky objects. To increase the transport capacity available, the rear-seat backrests may be folded down in an asymmetric split, expanding loading capacity to a substantial 59.7 cu ft.

An automatic tailgate opening and closing function is available as an option on the BMW X6 allowing the driver to vary the final position of the tailgate when open. This helps to reduce the risk of damage, for example in an underground car park or garage with a low ceiling.

Perfect combination of superior dynamics and outstanding comfort.

A new type of vehicle and a new driving experience, the BMW X6 definitely offers the best of both worlds. In terms of driving dynamics, the first-ever Sports Activity Coupe offers new dimensions defined by a considerable enhancement of agility, unique stability in fast bends and safe traction on slippery surfaces. Powerful engines, BMW's intelligent xDrive all-wheel-drive technology, Dynamic Stability Control, optional Active Steering and Adaptive Drive, as well as Dynamic Performance Control featured for the first time on the BMW X6 even as standard equipment, set the foundation for superior driving dynamics at all times.

Even with a moderate, reserved style of motoring, Dynamic Performance Control optimizes steering precision most considerably, enabling the BMW X6 to handle even difficult driving conditions through the outstanding quality of its drive and suspension technology.

Driving dynamics with intelligent control: Integrated Chassis Management.

The vehicle's drivetrain and suspension systems interact perfectly with BMW's Integrated Chassis Management. This high-performance electronic control ensures perfect harmony of drivetrain and suspension functions within fractions of a second, spelling out maximum driver control and supreme performance wherever you go and at all times.

Even under a sudden change in driving conditions for example, on varying surfaces, in spontaneous steering maneuvers, when accelerating or applying the brake abruptly, ICM reacts with the utmost precision to the xDrive, DSC and Dynamic Performance Control actuators and to Active Steering when fitted as an option. In all cases, the nature and scope of such intervention is appropriately masterminded to ensure not just maximum driving stability, but also optimum dynamics.

BMW's X Models already available today owe their outstanding agility largely to the supreme performance and qualities of ICM. Now the central control unit has an even greater and more progressive influence on driving dynamics in the new BMW X6, since it is also able to use the actuators serving for BMW's new Dynamic Performance Control. Depending on driving conditions and with fully variable management, the power of the engine is no longer split "just" between the front and rear axle, but also - through Dynamic Performance Control - between the left and right rear wheel, feeding additional power to the most appropriate point where it can be conveyed best to the road.

This drive technology quite unique in the market enhances the agility, steering precision and tracking stability of the car in corners as well as its traction on slippery surfaces, significantly improving driving dynamics in all cases and under all conditions.

As a result, Dynamic Stability Control is only required to cut in by applying the brakes electively on the appropriate wheel or wheels when the vehicle really reaches the extreme limits to driving physics. The world's first Sports Activity Coupe thus offers the driver the truly fascinating experience of being able to handle even the most demanding driving situations with sporting style and dynamic performance never seen before.

The drivetrain and suspension technology of the BMW X6 ensures the highest conceivable level of safety, precision and driving pleasure on all surfaces whether rough or smooth. The foundation of this purpose is provided by suspension technology quite unique in the segment of BMW X Models. The front axle, for example, is a double track control arm configuration applying the double joint principle for dynamic lateral acceleration, superior tracking stability and minimization of forces acting on the steering wheel. Appropriate front axle kinematics, in turn, ensure optimum front wheel camber on the road at all times, the BMW X6 thus maintains supreme grip and road-holding even under the most dynamic conditions.

At the rear, the BMW X6 features BMW's patented Integral IV axle serving to harmonize superior comfort with equally superior dynamics. And now this lightweight construction has been specifically optimized for the Sports Activity Coupe in many respects, with the entire rear axle configuration being appropriately adjusted to the specific demands of this model, for supreme sportiness and performance.

The wheel mounts, rear axle sub frame and four track arms efficiently take up the dynamic and drive forces flowing into the suspension, reducing any elastic distortion of the wheel mounts, while soft swinging mounts provide appropriate longitudinal suspension and optimize the roll quality of the wheels. Effectively separating the road surface from the drivetrain, finally, the rear axle helps to ensure first-class noise control and ride comfort.

The BMW X6 comes as standard with 19-inch light-alloy wheels. Also featured as standard are run-flat safety tires, which enable continued driving even after a complete loss of pressure in the tires. Furthermore, the Tire Pressure Monitor system permanently monitors air pressure and warns the driver as soon as the air pressure in the tires drops more than 30 per cent below the ideal level.

BMW xDrive: intelligent all-wheel drive for enhanced dynamics and optimum traction.

Permanent all-wheel drive with electronically controlled, variable distribution of drive power between the front and rear axles gives all BMW X Models not only superior traction, but also enhanced driving dynamics. Indeed, BMW xDrive gains its superiority as an intelligent all-wheel-drive system by distributing drive power front to rear by way of an electronically controlled multiple-plate clutch according to driving conditions, in exactly the right dosage and to the axle with grip.

In normal driving situations BMW xDrive distributes drive power in a 40 : 60 split front-to-rear, with sensors consistently measuring wheel slip. Hence, the system is able within a fraction of a second to vary the distribution of drive forces, with BMW xDrive-unlike conventional all-wheel-drive systems-anticipating the upcoming situation and not just responding once a wheel has started to spin. This serves to stabilize the vehicle even before the driver notices any need for action.

On the new X6 with Dynamic Performance Control, handling and stability are enhanced to an even higher level with the ability to multiply torque to an individual rear wheel for yaw control. With the combination of xDrive and Dynamic Perforance Control, the X6 is able counteracting even the slightest trend to over- or under-steer right from the start at the earliest conceivable point with the positive effects on the driver's sense of driving dynamics.

Unparalleled agility and tracking stability thanks to xDrive and Dynamic Performance Control.

The positive effect of Dynamic Performance Control on the agility of the BMW X6 is clearly seen right from the start. In conventional everyday traffic, the vehicle steers into corners with significantly enhanced precision at any speeds.

Dynamic Performance Control likewise enhances the handling and, indeed, the overall control of the BMW X6 in sudden steering maneuvers and at particularly high speeds in bends. If the vehicle begins to understeer or push to the outside of a corner BMW xDrive and Dynamic Performance Control will dynamically shift torque to the outside rear wheel in order to are able to counteract the understeer. On the other hand, if the vehicle threatens to over-steer, xDrive reduces the transmission of power to the rear wheels then the Dynamic Performance Control transfers torque and drive forces from the outer rear wheel and diverts these forces to the inner rear wheel.

This intervention in the interest of greater stability is so quick and finely controlled that the driver will not even notice what is happening. What he will notice, however, is that the BMW X6 ensures exceptional steering precision and vehicle balance all the way to the extreme limit.

Unique: Dynamic Performance Control enhances steering precision also when the driver takes his foot off the gas pedal.

A further particular feature of Dynamic Performance Control is that engine power and torque are split variably between the rear wheels not only when the engine is "pulling" the vehicle, but also in overrun. This is made possible by the addition of a planetary gear set and a multiple-plate clutch operated by an electric motor on both output sides of the rear differential. With this configuration Dynamic Performance Control is able to vary the distribution of drive power also when the driver takes his foot off the accelerator.

The BMW X6 is the first vehicle in the world to offer such a stabilizing effect independent of engine load and drive power.

Dynamic Performance Control also serves to optimize traction on a slippery surface. With its ability to vary the transmission of engine power specifically as required between the two rear wheels, Dynamic Performance Control serves to improve traction and pulling force whenever the vehicle is running on different surfaces from one side to the other, for instance, with asphalt on one side and a snowbound surface on the other. Any differences in the frictional coefficient between the wheels on the left and right (modal split) are offset by Dynamic Performance Control specifically sharing out drive forces on the rear axle.

Easily viewable on the instrument cluster, the driver receives a clear message showing the interaction by Dynamic Performance Control. By simply pressing the lever on the steering column, the driver is informed of the current distribution of drive power via a bar diagram showing how much power is going to each of the four drive wheels at any given point in time.

DSC intervening only when driving to the limit.

The difference in drive forces between the two rear wheels provided by Dynamic Performance Control can be as high as 1327 lbs-ft (1800 Newton-meters). But even then, all the driver will feel when Dynamic Performance Control intervenes is a - significant - increase in agility, traction and driving stability. As a result of Dynamic Performance Control's intervention, the Dynamic Stability Control intervenes much less frequently than before. In practice, this means that the driver is able to use the full drive power and torque of the engine much longer than with a conventional system, DSC acting on individual wheels or reducing engine power only when the driver really pushes the car to the extreme limits of physical performance.

In addition, DSC in the new BMW X6 offers a wide range of additional functions serving to promote safe and dynamic motoring including: ABS anti-lock brakes; Automatic Stability Control; Trailer Stability Control; Hill Descent Control; Dynamic Brake Control, automatically maximizing brake pressure when required in the interest of minimum stopping distances; Cornering Brake Control; and, finally, Active Cruise Control complete with its own brake application function.

The Automatic Differential Brake serves as a transverse lock between the two wheels, and Fading Compensation increasing brake pressure as required under extremely high brake temperatures, helps to maintain the brake forces required even under extreme conditions. Regular Dry Braking, in turn, optimizes brake performance in wet conditions, while the Start-Off Assistant enables the driver to set off more smoothly and easily on an uphill gradient.

The new BMW X6 features a parking brake operating both electromechanically and hydraulically, activated or released simply by pushing a button.

Reflecting the high standard of driving dynamics offered by the BMW X6, DSC also comes with Dynamic Traction Control as a special function, raising the DSC response thresholds to a higher level, allowing a particularly sporting and active style of motoring, and enabling the driver to set off smoothly on snow or in loose sand with the drive wheels intentionally spinning slightly.

Supported by a wide range of DSC functions, the high-performance brake system featured in the BMW X6 ensures excellent stopping power under all conditions. Inner-vented discs on all four wheels take up brake energy, newly developed lightweight brakes with floating aluminum calipers front and rear, guarantee extremely good resistance to fading and maximum brake comfort on the top-of-the-range BMW X6 xDrive50i.

Active Steering for a particularly sporting and comfortable style of motoring.

The BMW X6 is also available with Active Steering as an option. This very special system developed by BMW offers exactly the right steering ratio at all speeds, maintaining direct steering behavior up to a speed of about 55 mph, as required particularly for a sporting and active style of motoring. A further advantage in this case is that the driver only has to turn the steering wheel twice from lock to lock when parking. At higher speeds, on the other hand, Active Steering offers a more indirect transmission ratio in the interest of steady directional stability and, as a result, enhanced motoring comfort.

On the BMW X6, Active Steering is combined with Servotronic, thus making an active contribution in stabilizing the car in the event of over-steer in bends or particularly demanding brake maneuvers. When applying the brakes on different surfaces left and right, for example, that is with a so-called modal split, Active Steering counter-steers discreetly but firmly to prevent the car from swerving out of control.

Unique: Adaptive Drive with data transfer via FlexRay.

Carefully harmonized interaction of the vehicle's anti-roll bars and dampers masterminded by Adaptive Drive is another unique feature in the segment of BMW X Models. Indeed, this combination of active body roll control and variable damper adjustment available as an option gives the new BMW X6 incomparably superior driving behavior.

Using sensors in the vehicle, Adaptive Drive constantly monitors and calculates data on road speed, the steering angle, longitudinal and lateral acceleration, body and wheel velocity, as well as ride and damper position. Applying this information, the system acts directly on the anti-roll bar swivel motors and the electromagnetic valves in the dampers, varying body roll and the damping effect appropriately at all times and in all situations. Simply by pressing a button, the driver is able to choose either a sporting or a comfortable setting on Adaptive Drive.

BMW Adaptive Drive uses high-speed FlexRay data transmission for fast and reliable coordination of data. This system, developed to production standard by a development consortium under the leadership of BMW offers a standard of data transfer capacity never seen before - and BMW is the first carmaker in the world to use FlexRay technology in a regular production car.

Superior engine dynamics in both the xDrive35i and xDrive50i.

Through its superior suspension technology, the BMW X6 is able to convert all the power of the engine safely and consistently into driving dynamics under virtually all conditions and on all kinds of surfaces. And the engines available in the first Sports Activity Coupe set standards themselves in terms of muscular performance, superior running smoothness, and outstanding efficiency in their respective class. Both the xDrive35i and xDrive50i feature Twin Turbo technology engines, representing the latest in state of the art engine technology-with the power range extending from 300 hp to 400 hp.

The BMW X6 xDrive50i is powered by an all-new eight-cylinder, while the BMW X6 xDrive35i features the most powerful straight-six within the engine portfolio of Germany's leading premium car maker. The performance characteristics and efficiency for both of these engines benefits from the exclusive combination of Twin Turbo technology and High Precision Injection available only from BMW. The principle of combining two turbochargers and direct gasoline injection applied for the first time on the straight-six is now also to be admired on the new V8.

A class of its own: The new eight-cylinder with Twin Turbo Technology.

With Ultimate Driving Performance as the most important feature-this applies to BMW's X Models and to BMW's eight-cylinder engines-the BMW X6 is adding an incomparably dynamic variant to the line-up of BMW X Models, with the world's first Sports Activity Coupe boasting a particularly sporting and dynamic eight-cylinder.

Displacing 4.4 liters, the new V8 engine with Twin Turbo technology and direct gasoline injection (High Precision Injection) develops maximum output of 400 hp throughout a broad range of engine speed from 5,500-6,400 rpm. Engine torque reaches its peak of 450 lb-ft throughout an unusually large speed range from 1,800-4,500 rpm. The spontaneous, intense and long-lasting thrust generated in this way is the result of Twin Turbo technology already featured on BMW's most powerful straight-six combined with High Precision Injection. The cooling effect of direct fuel injection also ensures a compression ratio quite unusual on a turbocharged engine, helping to give the engine an even higher level of all-round efficiency.

The position of the turbochargers and catalytic converters in the V-section between the two rows of cylinders is likewise an innovation in technology allowing particularly compact engine dimensions and at the same time requiring new configuration of the intake and exhaust ducts. This means shorter intake and exhaust manifolds and larger cross-sections significantly reducing pressure losses on both the intake and exhaust side.

The all-aluminum V8 engine developed for the BMW X6 offers all the qualities typical of an eight-cylinder in incomparably sporting style. In practice, this means a combination of superior torque at low engine speeds with an ongoing surge of power and performance up to the higher speed range.

The BMW X6 xDrive50i accelerates from 0-60 mph in just 5.3 seconds and boasts ample power reserves for exceptional acceleration also at higher speeds. When equipped with the optional 20 inch wheels with performance tires, the top speed is a truly impressive 155 mph limited electronically by the engine control unit.

Twin Turbo technology featured for the first time on an eight-cylinder gasoline engine.

The power and performance characteristics of the new V8 result to a large extent from Twin Turbo technology, the use of two turbochargers for the first time on an eight-cylinder engine serving to boost both engine output and torque with maximum efficiency. Each of the two turbochargers supplies compressed air to four cylinders at a time, ensuring particular spontaneity and a direct reaction to the gas pedal.

As with the straight-six featuring Twin Turbo technology, the "turbo lag" typical of a turbocharged engine with conventional technology, that is the time until the turbocharger builds up its boost, is virtually eliminated through the combination of two small turbos and the direct injection calibration.

A further advantage is that the engine revs up smoothly, maintaining its high torque consistently throughout an unusually broad range of engine speed. In its power and performance characteristics, therefore, the engine is comparable to a significantly larger normal-aspirated engine while offering the advantage of much lower weight and reduced package size.

Not only are the dimensions and weight of the new V8 unusually modest, but the fuel consumption is also exceptionally low for an engine of this caliber. A significant factor contributing to the superior fuel economy is double-VANOS infinite camshaft management, a technology characteristic of BMW engines. Indeed, this technology is also one of the reasons why the V8 - over and above its superior fuel economy - develops exceptionally high torque from low engine speeds.

High Precision Injection also plays a key role in the efficient use of fuel. This second generation of direct gasoline injection uses piezo-injectors positioned directly next to the spark plugs in the cylinder head and delivering fuel into the combustion chambers at a pressure of 2900 psi. The advantage is extremely precise dosage of fuel, with the further benefit of reduced emissions and improved engine acoustics. And last but not least, it almost goes without saying that the engine fulfils both the US ULEV II emissions standard as well as the EU5 requirements in Europe.

The new V8 engine is the most efficient engine in its class. Combined with a number of further technologies developed in the overall context of BMW EfficientDynamics, the engine gives the BMW X6 xDrive50i fuel consumption and emission figures significantly better than other eight-cylinder vehicles competing with the BMW X Models.

BMW's most powerful inline-six in the world's first Sports Activity Coupe.

The second gasoline-powered version of the BMW X6 boasts the most powerful inline-six within BMW's engine portfolio: Maximum output of the engine featured in the BMW X6 xDrive35i is 300 hp from an engine capacity of 3.0 liters. This superior power is maintained consistently between 5,800 and 6,250 rpm, with maximum torque of 300 lb-ft provided all the way from 1,400-5,000 rpm. This gives the six-cylinder superior power and performance from an unusually early point on a gasoline engine, subsequently maintaining this high power throughout a broad range of engine speed.

Like the new V8 engine, the engine in the BMW X6 xDrive35i offers the exclusive combination of Twin Turbo technology and High Precision Injection for incomparable power and performance, plus a standard of economy quite unique in comparison with the engine's dynamic driving potential.

On the inline-six with Twin Turbo technology, two exhaust turbochargers each supply compressed air to three cylinders. The small mass inertia of the relatively compact turbochargers optimizes response to a significantly higher degree on this engine, building up charge pressure without the slightest delay from low engine speeds. The result is a rapid increase in power and torque further promoted by infinitely variable double-VANOS camshaft control.

This characteristic of BMW's Twin Turbo gasoline engines is unique world-over and offers an exceptionally high standard of power and flexibility on the road. In practice, this allows the driver to use the superior torque of the engine right from the start when accelerating, with engine power then remaining consistent over a wide speed range.

The exceptional dynamism of the engine is further enhanced by its high compression ratio, again an advantage made possible by High Precision Injection: With the fuel/air mixture being cooled as a result of direct injection, the compression ratio can be increased to a higher level than on a turbo-charged engine with intake manifold injection. Engine efficiency is improved accordingly, offering more power on less fuel.

The level of power offered by the inline-six with Twin Turbo Technology and High Precision Injection is equal to a level that only a much larger eight-cylinder was able to provide in the past. But at the same time BMW's most powerful six-cylinder offers a much higher standard of fuel economy and, thanks to its all-aluminum crankcase, is much lighter.

BMW EfficientDynamics: wide range of features serving to reduce fuel consumption and emissions - and all coming as standard.

Offering a wide range of features serving to enhance efficiency on and around the engine, all versions of the new BMW X6 ensure a particularly good balance of power, performance and economy - and all these features come as standard.

The all-round efficiency of the BMW X6 is further optimized by on-demand control and activation of the engine's ancillary units helping to significantly reduce the power required for the fuel and steering assistance pumps and thus again saving energy in the process.

For example, the drive belt for the a/c compressor, comes with an independent clutch automatically disconnecting the compressor as soon as the driver switches off the air conditioning and thus reducing the drag forces generated by the compressor to a minimum.

Further examples are the use of tires with reduced rolling resistance and the optimization of the car's aerodynamics. The cooling air flaps behind the BMW kidney grille and in the air intake, for instance, are controlled electronically, helping to reduce the air drag of the vehicle when closed and only being opened in response to greater demand for cooling.

Automatic transmission designed for sports motoring.

Power is transmitted on the BMW X6 in standard trim by six-speed sport automatic transmission with a particularly sporting gearshift now enhanced to an even higher level.

The automatic transmission chooses the appropriate gear with incomparable spontaneity, precision and efficiency, benefiting both the comfort and driving dynamics of the BMW X6. The automatic transmission shifts gears either in response to the electronic gear selector lever or the gearshift paddles on the steering wheel.

Intelligent lightweight technology for enhanced dynamics and solidity.

Like the other models in the BMW X range, the BMW X6 boasts a particularly strong and sturdy body. To keep weight to a minimum despite this outstanding solidity, BMW's engineers developing the new model focused consistently from the start on intelligent lightweight construction. Both the choice of materials as well as the arrangement and geometry of the various support bars, rods and other support elements are based on an overall concept combining maximum crash safety with supreme agility on the road.

The new BMW X6 not only includes front and side airbags as standard, but also curtain-type Head Protection System airbags at the side, protecting the occupants both front and rear from injury. Additional features include: three-point inertia-reel belts on each seat, with belt force limiters together with a belt tightener on the front seat; crash-activated headrests to prevent cervical spine injury in the event of a collision from behind, that come standard on the front seats.

All restraint systems are masterminded by one central electronic safety "brain" monitoring the type and severity of a collision and activating the most effective protection units in each case. The frontal airbags, in turn, come with a gas generator operating in two stages and thus activating the airbags with varying intensity, depending on the severity of an accident.

In the event of an imminent rollover, the car's rollover sensor activates both the curtain airbags and the belt latch tensioners. Indeed, this integration of the system with DSC Dynamic Stability Control guarantees appropriate function of the overall safety system in good time whenever necessary. And to avoid accidents from behind the new BMW X6 comes with BMW's two-stage brake lights.

The BMW X6. The first Sports Activity Coupe.

The BMW X5 has already demonstrated most clearly that dynamic driving qualities are a decisive criterion also with a vehicle of this class and caliber. The BMW X3, in turn, has added outstanding agility as a further factor crucial to success in this segment. And now the BMW X6 focuses again on these priorities, raising them to an even higher level. As a result, the world's first Sports Activity Coupe from BMW once again sets the standard in a market segment characterized by particularly dynamic growth And at the same time the BMW X6, through its concept and drive technology, clearly proves and confirms the exceptional innovative power of Germany's premium carmaker.

The new BMW X6 is expected to be in US BMW Centers in the second quarter of 2008. Options, pricing and precise launch timing details will be communicated as the launch window nears.

Base Price: 2007 Porsche RUF CTR3 - $510,000 / 380,000 € + VAT (last update: 4/12/2007)

Exactly 20 years after the legendary CTR “Yellow Bird” and 10 years after the second CTR, RUF announces the all new CTR3. The RUF CTR3 was presented at the grand opening of the new RUF facility in Bahrain. While the first two CTR generations still had their engines in the rear, the new CTR3 has a mid engine design. However, one thing that the CTR3 has in common with its two predecessors is that it is a pure driving machine. The CTR3 is made to involve the driver in the driving experience.

The mid engine design provides exceptional balance and agile handling, while the longer wheel base provides better driving stability at high speed. The body of the CTR3 is a completely new development which is not based on any existing mid engine concept. It is aerodynamically designed for high speed. The body is constructed in steel, aluminum and kevlar-carbon. Zinc dipped steel is used for the front structure and the passenger compartment. The engine and transmission are fixed in a space frame and birdcage. The passenger compartment is protected the latest version of the famous RUF Integrated Roll Cage which is integrated into the A pillar and birdcage. The doors, with integrated side impact protection beams, and the front hood are made of aluminum. The body shell is made of kevlar-carbon composite.

The body styling was created by Ben Soderberg, who is responsible for the RUF design.

RUF has 30 years of experience with turbo charged boxer engines. The CTR3’s twin turbo charged 3.8 liter flat six cylinder engine has an output of 700 bhp at 7,000 rpm. The maximum torque is 657 lb-ft at 4,000 rpm. This engine design combines a compact construction with high performance. Each turbo charger is provided an intercooler which is placed in front of each rear wheel.

The sequential shift six speed transmission in the CTR3 is a new design and is transversally mounted. It can manage torque of up to 885 lb-ft. A shift indicator on the dashboard shows the gear in use. A limited slip differential is provided to maximize performance.

The sport suspension is designed for high level driving dynamics and safety. The front axles use McPherson struts and an anti-roll bar. The rear axles utilize motor sport technology with horizontal coil over shock absorbers fixed over push rods connected to the wheel carriers.

The brake system is designed to match the high performance of the engine and suspension. Both front and rear axles utilize 6 piston fixed light alloy calipers and ventilated, cross drilled ceramic composite discs. Each brake disc is 380mm in diameter. A specially designed Bosch anti-lock braking system is standard.

The CTR3 rolls on forged aluminum wheels with central locking. At the front 255/35 ZR19 tires are mounted on 8.5” X 19” wheels, while at the rear 335/30 ZR20 tires are mounted on 12.5” X 20” wheels.

The interior can be designed to the customer’s taste, from a functional light weight finish to sporty luxury finish with a leather and alcantera. The aluminum gear shift lever for the sequential shift transmission is a central unit to the interior. In addition, the 260 mph speedometer shows the driver that the CTR3 is made for high performance.

The lightweight construction allows for an empty weight (according to DIN) of 3,086 lbs. The result is a power to weight ratio of only 4.4 lbs per bhp.

The performance of the CTR3 is incredible. The acceleration from 0-62 miles per hour takes only 3.2 seconds. The top speed is 235 mph.

Base Price: 2009 Jaguar XF - n.a. (last update: 8/28/2007)

Challenging convention and setting its own rules, the new Jaguar XF fuses the style and performance of a sports car with the refinement, space and sophistication of a luxury saloon. This is the beginning of a new era for Jaguar.

The new XF: a dramatic expression of a bold new Jaguar design language, with a driving experience that exceeds expectations created by the striking appearance: relaxed and confident, with outstanding ability and control.

Resolutely true to the Jaguar philosophy of creating Beautiful, Fast cars, the XF goes further, adding a new dimension to the marque. The four-door XF has the visual excitement of a coupe, but room inside for five adults to enjoy an interior wholly contemporary in style yet uniquely Jaguar.

Exterior Design

The XF’s visual emphasis is sporty, muscular and dynamic – a character defined by a sweeping silhouette inspired by the XK, a powerful grille, dramatic side window graphics and, of course, strong Jaguar ‘shoulders’. The look, however, does not come at the expense of efficient packaging. The XF’s waistline rises to meet the roof rather than the roof coming down to meet the waist, which improves interior space. This rising waistline gives the XF a higher tail than any previous Jaguar, providing the twin benefits of much improved aerodynamic performance, together with substantially increased luggage volume. At a maximum of 540 liters (500 with a spare wheel) the XF’s boot is the equal of anything in the class and betters most rivals.

The XF’s Jaguar character is defined by its face – centered around a bold intake grille which provides a focal point for the feature lines which stream back over the bonnet and cabin, it has inherent visual strength. The grille’s mesh pattern is itself an important element of external jewellery, the woven pattern an emotional design signature that is quintessentially British, with strong sporting connotations.

Interior

The interior design maximizes the feeling of space, with driver and passenger seating positions, the relationship of seats to window areas, and the volume and versatility of stowage options all contributing. New thinking on seat design – the front seats are deliberately sculpted and reduced in size (but not comfort) – liberates space and makes access easier, too. The increased track and best-in-class rear seat width means tall adults can sit in complete comfort. And while the XF roofline might say ‘coupe’, the rear headroom says ‘saloon’ better than many rivals.

Just as the XF’s exterior defines a new design direction, its interior moves from traditional themes to contemporary, sporting luxury - emphasized by ‘surprise and delight’ features such as the JaguarDrive SelectorTM and the rotating vents; through the use of sophisticated new materials; and by all-new graphics and interior lighting systems.

Engine

The new XF will be available with a choice of four engines - 2.7-liter V6 turbodiesel, 3.0-liter V6 petrol, 4.2-liter naturally aspirated V8 petrol, and 4.2-liter supercharged V8 petrol (depending on market).

The 4.2-liter supercharged V8 comes with a ribbed aluminum block and cylinder head, which is very light but extremely strong, and its superb structural stiffness minimizes radiated engine noise and increases mechanical reliability. The V8’s exhaust system has also been completely retuned to remain quiet at cruising speeds but deliver a substantially more purposeful V8 roar under hard acceleration.

The engine uses a highly efficient rotor-type supercharger, belt-driven from the crankshaft. It develops 420 bhp, and 408 lb-ft of torque from low engine speeds. Just as important as the supercharged engine’s peak torque is the way the usable torque is spread across a wide rev range - with at least 86 percent of the peak from 2000 rpm to maximum engine speed.

A superior six-speed automatic transmission – renowned as one of the best in the world and already proven in other Jaguars - is used on all versions of the new XF. There is no manual gearbox option. The transmission is a key element in the XF's sporting character, its adaptive gear-changing strategies responding both to road conditions and the way the car is being driven, giving the smoothest shifts and optimum performance. Adding another layer of driver focus, the transmission is controlled by the new JaguarDrive Selector with the option of manual selection through Jaguar Sequential Shift. The JaguarDrive Selector is also used to access the XF’s Sport mode which uses shift-by-wire technology pioneered on the XK.

Base Price: 2008 Mercedes-Benz SLK 55 AMG Black Edition - 92,500 € (last update: 8/28/2007)

The new Black Series from Mercedes-Benz is an even more driver-focused variant of the V8-powered SLK 55 AMG Roadster, using motorsport-inspired technology to deliver scintillating performance and enhanced driving dynamics.

Output from the 5.5-liter AMG engine is boosted from 360 bhp to 400 bhp and 45 kg has been shaved off the kerbweight through the use of lightweight components including a new fixed hard top. As a result, the 0 to 60 mph dash drops to 4.3 seconds, while 125 mph is, where permitted, clocked up in just 15.5 seconds – a full two seconds quicker. Top speed is no longer restricted to 155 mph, and the car can reach 173 mph.

The exclusive nature of the SLK 55 AMG Black Series is signaled by even more muscular front wings made from ultra-light carbon fiber-reinforced plastic (CRP) and a restyled AMG front skirt with carbon fiber inlays. Large air intakes and side air outlets ensure a sufficient flow of air to the enlarged engine oil cooler and new transmission and steering oil coolers.

The SLK’s standard vario roof with its hydraulic closing mechanism has been replaced with a purposeful fixed hard top which has a central section in black carbon-fiber CRP. It means that not only is the car’s centre of gravity lower, there is also a significant weight loss – it now tips the scales over seven stones lighter than the standard car, at 3295 lbs.

The motorsport theme continues inside: two specially developed AMG sports bucket seats without side airbags offer superb lateral support and are trimmed in a black pearl velour complete with silver AMG logos. They are complemented by a leather and Alcantara trimmed steering wheel derived from that used in the FIA Formula One World Championship Official Safety Car, and lightweight AMG carbon fiber internal door centre panels.

The V8’s power output of 400 bhp at 5,750 rpm compares with the standard AMG model’s 360 bhp, produced at the same engine speed. It develops an even more muscular 384 lb-ft of torque at 3,750 rpm. Key enhancements include a modified air intake, an AMG sports air filter and a newly-developed exhaust system. Power continues to be fed through an AMG Speedshift 7G-TRONIC transmission with a manual drive program and steering wheel-mounted aluminum shift paddles.

Naturally the chassis has been modified to match the increased performance capability of this special series SLK 55 AMG. Racetrack-optimized, AMG height-adjustable torsion suspension, including adjustable dampers permits even more impressive cornering ability. 19 inch ultra-light AMG forged alloy wheels with 235/35 ZR19 (front) and 265/30 ZR19 (rear) Pirelli P Zero Nero tires replace the 18 inch items of the standard car. Greater body rigidity is provided by a brace across the engine bay, and for those looking for even sportier handling, there’s a limited slip differential available, priced at 3,475 euros in Europe.

There is stopping power to match the performance and the front wheels continue to feature composite technology to minimize braking distances, optimize sensitivity and ensure high resistance to fading. The composite brake discs are now 360 mm in diameter, up from 340 mm. The 330 mm internally ventilated and perforated brake discs at the rear are retained.

The SLK 55 AMG Black Series may possess a level of driving dynamics orientated towards track use, but it is also a car eminently suited to everyday driving and provides the safety, durability and quality that come as standard across the Mercedes-Benz range. The Black Series is also offered with three additional AMG packages for even greater exclusivity: an AMG Leather package includes leather seats, dash, centre console, centre armrest, door panels and doorbags, and anti-roll bars for 6,310 euros. An AMG Interior Carbon Fiber package includes carbon fiber instrument cluster covers, steering wheel multi-function button covers, gearshift lever and door sill panels for 2,630 euros. An AMG Exterior Carbon Fiber package has carbon fiber front grille inserts, external mirror covers and rear boot spoiler trim, for 4,325 euros.

The SLK 55 AMG Black Series is priced at 92,500 euros and is available by special order from Mercedes-Benz Retailers in Europe now. Prices and availability in the US is not yet confirmed.

Mercedes-Benz Debuts SL63 AMG Roadster
MONTVALE, NJ – Mercedes-Benz is unveiling a fourth member of its iconic SL sports car family – the SL63 AMG. Perhaps the sportiest SL roadster ever, the new SL63 AMG is powered by a 6.2-liter, 518-hp, all-AMG V8 engine that’s coupled to a newly developed MCT transmission.

Featuring an innovative start-up clutch that replaces a conventional torque converter, the seven-speed MCT (for multi-clutch technology) transmission combines the direct connection of a manual gearbox with the lightning-quick automatic gear shifts of a Formula 1 race car. Topping off the SL chassis is an even more agile AMG sports suspension based on the Mercedes-Benz ABC active suspension.

MCT Transmission – The Best of Both Worlds

Providing the direct feedback of a manual transmission with the total convenience of an automatic, the new seven-speed MCT with AMG Speedshift is an all-new design available only in the new SL63 AMG. Featuring seven speeds, four shift modes and a double-clutching function, the MCT transmission offers impressive versatility and even faster shift times.

At the heart of the new AMG Speedshift MCT seven-speed sports transmission is a new start-up clutch, which runs in an oil bath and replaces a conventional torque converter. Thanks to its low rotational mass, the start-up clutch helps the transmission respond instantaneously and dynamically with no slip.

Fitted with four drive modes: “C” (Comfort), “S” (Sport), “S+” (Sport plus) and “M” (Manual), the transmission provides customized shift control for maximum driving pleasure, and does so with no interruption of power. In Comfort mode, smooth shifts coupled with a “soft” accelerator response are set up for silky smooth power transfer. In Sport mode, the engine and transmission interact quicker – upshifts and downshifts take place at higher engine speed. Gearshifts are around 20 percent faster than in Comfort mode. Switching to the Sport Plus mode cuts another 20 percent off shift times, while the sportiest mode, Manual, reduces shifting times by another 10 percent – a total reduction of 50 percent compared with Comfort mode. In Manual mode, the gearshifts take just 100 milliseconds.

Ultra-fast, spontaneous multiple downshifts are another forte of the new MCT sports transmission. For instance, kickdown will shift directly from seventh down to fourth gear or from fifth to second. In the “S” (Sport), “S+” (Sport plus) and “M” (Manual) modes, an automatic double-clutching function is active. Every manual or automatic downshift is accompanied by precisely metered double-clutching – from “S” through “S+” to “M” incrementally. Not only does double-clutching make driving more fun, but virtually load-free downshifting minimizes any jerking, a special benefit when braking into a curve.

The First Engine Developed From the Ground Up by AMG

The SL63 AMG is powered by an AMG 6.2-liter V8 engine that features four valves per cylinder, variable valve timing, bucket tappets (rather than rocker arms) and a variable intake manifold. Sharing no parts with Mercedes-Benz V8 engines, the 6.3-liter engine was a completely autonomous development at AMG.

Built almost completely from a high-strength silicon-aluminum alloy, the cylinder bores make use of a twin-wire-arc-sprayed (TWAS) coating, a process that results in impressively low friction and running surfaces that are twice as hard as conventional cast-iron cylinders.

The 6.3-liter engine block boasts an especially rigid bedplate acting as the overall support of the main bearings (similar to a one-piece set of main bearing caps), cast-in steel reinforcements and a sturdy closed-deck layout in the cylinder head area. The high-flow intake and exhaust ports form a vertical straight line, helping the 6.3 AMG engine rev freely to more than 7,000 rpm, yet the highly flexible AMG engine still produces nearly 90 percent of its peak torque at only 2,000 rpm.

A finely balanced crankshaft with six counterweights spins in five main crankshaft bearings. The crankshaft counterweights feature heavy metal plugs – a detail usually found only in racing engines – which means they can be significantly smaller, increasing power by reducing rotational inertia and oil drag.

Each forged connecting rod is precisely “cracked” with the help of a laser beam, so the irregular fracture contributes to its strength when the two halves are clamped around the crankshaft. The connecting rods and lightweight pistons are matched for extremely close weight tolerances that contribute to smooth running at high speeds. Small nozzles in the engine block spray cooling oil onto the underside of each piston crown.

“Bucket” Followers Instead of Rocker Arms

Twin overhead camshafts in each cylinder bank open the 32 valves via bucket-type followers. In other words, instead of rocker arms, the cam lobes sweep across the flat top of the followers, which sit directly on top of the valve stems. This space-saving design provides a very stiff valve train that allows for large valve openings and dependable high-speed operation for maximum horsepower and torque. However, in contrast to racing engines, each bucket incorporates a hydraulic lifter that automatically maintains valve clearance, which allows for long service intervals and low costs.

The AMG V8 makes use of variable intake and exhaust valve timing to maximize efficiency and torque over a wide RPM range. Valve timing can be automatically adjusted within a range of 40 degrees using electro-hydraulic vane-type adjusters on each camshaft. At part throttle, the valve timing adjuster keeps the exhaust valves open as the intake valves are opening, using this valve overlap for internal exhaust gas recirculation, reducing exhaust emissions and improving fuel economy. However, approaching full throttle, the camshaft adjustment optimizes valve timing for maximum power. The intake cams are driven by a double chain from the crankshaft, and small gears on the intake cams in turn drive the exhaust cams.

The SL63 Gets Unique Styling Touches

The SL63 comes with a distinctive AMG front hood that’s noticeably different from other SL models, as well as a new front apron with a more pronounced wedge shape, larger cooling air intakes, and a black grille. Bi-xenon headlights with black surrounds and large round fog lights ringed in chrome and set well to the side emphasize the vehicle’s width.

Hot air from the engine exits through side air outlets in the front fenders and from the “gills” behind the front wheels. Trim panels finished in matte silver with “6.3 AMG” lettering catch the eye, as do new outside mirrors with arrow-shaped LED turn indicators.

SL63 AMG body styling also includes deeper AMG side sill panels and a beefy-looking rear apron that incorporates a large black air diffuser and two pairs of chrome tailpipes. An AMG rear lip spoiler on the trunk lid reduces lift, especially at high speeds.

Finished in nappa leather and genuine carbon fiber, the interior features standard AMG sport seats, an AMG three-spoke steering wheel and a sport instrument cluster with red tach and speedometer needles that swing to the max position and back whenever the ignition is turned on.

Optional Performance Package for the SL63 AMG

An optional Performance Package is also available for the SL63 AMG, which includes even higher-performance components that are well suited for sporty-minded drivers:

· Top speed raised to 186 mph · Vented ceramic front brake discs that are 15.3 inches in diameter · Multi-disc limited-slip rear differential with a 40 percent locking factor of for enhanced traction · 19-inch AMG twin-spoke forged light-alloy wheels · Staggered-width tires: 255 / 35 R 19 in front and 285 / 30 R 19 at the rear · AMG high-performance suspension based on ABC active suspension · Smaller AMG sport steering wheel with a flattened underside and silver-aluminum shift paddlesv

AIRSCARF Around the Head and Neck

All 2009 Mercedes-Benz SL roadsters are now available with AIRSCARF, an innovative feature that can extend the open-air driving season into the cooler months. Another technological first from Mercedes, AIRSCARF is an extra heating system built into the driver and passenger seats. At the touch of a button, warm air flows from vents in the head restraints, acting as an invisible scarf around the head and neck.

Testing revealed that warming just a relatively small area around the neck dramatically improves comfort in cooler weather. The AIRSCARF neck-level heating system blows warm air from the head restraints of the driver and passenger seats, allowing occupants to cruise comfortably with the retractable hardtop open in colder weather. AIRSCARF uses a heating element made primarily of barium titanate, which heats up in a matter of seconds when electrical current is applied.

Optional on the V8-powered SL AMG model and standard on the SL65 AMG, the AIRSCARF neck-level heating system even compensates automatically for changes in air temperature and vehicle speed. AIRSCARF comes with a three-speed switch and an electronic control module that monitors data from the speedometer as well as from inside and outside temperature sensors. AIRSCARF automatically adjusts the fan speed based on this information, and at the same time, the switch can override the automatic settings.

New Audio Technology

With its 6.5-inch color display screen, the standard COMAND system with GPS navigation has been refined with a new MMI interface and a four gigabyte hard drive as well as an integrated six-disc CD-DVD player and a Music Register for around 1,000 MP3 tracks. The interface makes it easy to connect an iPod, USB stick, memory card and other devices. Music tracks can be indicated on the COMAND display located on the center console as well as a smaller display in the center of the instrument cluster, and they can be selected easily using the buttons on the multi-function steering wheel.

Any Bluetooth-enabled cell phone will work hands-free – even with the phone in a pocket or purse, the audio is automatically muted when a call is made or received, and callers are heard over the audio system speakers. In addition, phone address book info can be displayed by the COMAND system

From Coupe to Roadster in 16 Seconds

At the push of a button, the SL’s retractable hardtop can be fully opened or closed in just 16 seconds, transforming the car from a quiet, weather-tight coupe to a top-down open-air convertible. A hydraulic pump and 11 computer-controlled hydraulic cylinders power the system, and roof operation is controlled by a switch on the center console. A clever folding design allows for a surprisingly large cargo area of 7.2 cubic feet when the top is down. With the top up, the trunk holds 10.2 cubic feet.

The World’s Safest Convertible

Widely acclaimed as one of the world’s safest convertibles, the SL provides sports car performance with all the built-in safety that’s expected from Mercedes-Benz. Since an open car can leave its occupants vulnerable in a rollover, Mercedes engineers met the challenge in the SL with the world’s first automatic roll bar.

Normally part of the interior’s rear-compartment surround structure, the padded, leather-covered bar pops up, locking in place in a third of a second if sensors detect an impending rollover. The driver can also raise and lower the bar by a switch on the console.

Shoulder belts are integrated directly into the seats for greater occupant protection, especially in roll­overs. The Mercedes SL was also the first car with side airbags, which are part of a safety system that includes dual front airbags and emergency tensioning retractors that tighten the seat belts in a collision.

V8 and V12 Power

The two AMG SL roadster models for 2009 feature a choice of V8 and V12 power. The SL63 AMG is powered by a 6.2-liter four-valve-per-cylinder V8 with 518 horsepower and 465 pound-feet of torque, while V12-powered SL65 AMG, makes 604 hp and a monstrous 738 lb.-ft. of torque.

AMG High-Performance Braking

Excellent stopping power for the SL is provided by large, four-wheel disc brakes enhanced with four-channel ABS anti-lock control. Matched to its power and speed capability, the SL63 AMG comes with large 14.2-inch vented rotors up front and 13.0-inch vented rotors at the rear, while the SL65 AMG boasts vented discs that are another 1.2 inches in diameter.

Also new are 19-inch AMG staggered-width alloy wheels – 8.5 and 9.5 inches wide – fitted with 255 / 35 R 19 (front) and 285 / 30 R 19 (rear) tires. With triple-spoke styling and a titanium grey finish, the AMG alloy wheels complement the new AMG body styling.

ABC Active Suspension Gives Cat-Like Agility

The SL chassis uses a fully independent, double-control-arm front suspension and the patented Mercedes-Benz five-link rear suspension. All SL models come with second-generation Active Body Control (ABC), the Mercedes-Benz active-suspension technology that virtually eliminates body roll in cornering, squat under acceleration and dive during braking.

Each SL uses software programming specific to the model, akin to tuning the spring rates, shock damping and roll stiffness of a conventional suspension. Special AMG struts with firmer damping and fully reworked systems such as ABS anti-lock brakes, Brake Assist, ASR traction control and ESP stability control complement the enhanced AMG chassis.

Mercedes-Benz engineers use ABC’s interplay of hydraulic, electronic and mechanical parts to reduce body roll by 68 percent (compared to the same vehicle with a conventional suspension), providing the driver with needed feedback through the vehicle chassis. A ‘Sport’ switch on the center console can make it 95 percent reduced roll, along with tighter shock damping. Active suspension solves the usual tradeoff between ride comfort and handling precision, so SL roadsters offer excellent comfort and league-leading handling.

Facelift for the SLK 55 AMG
The SLK 55 AMG is now even more dynamic: a new front apron and dark-tinted headlamps give this unique eight-cylinder roadster an even more athletic look even at a standstill. The handling dynamics of the SLK 55 AMG have also been sharpened. For the first time the car features the new direct steering with variable servo assistance, which makes the 360-bhp two-seater even more agile and responsive. The SLK 55 AMG is also the only car in its class to feature a V8 engine, while the improved AMG SPEEDSHIFT 7G-TRONIC transmission now offers even faster gearchanges.

The appearance of the sporty roadster now reinforces the car’s claim to special status even more emphatically. The redesigned front apron with a more pronounced arrow-shape, the modified Mercedes star, enlarged air dams and a black-painted transverse fin on the lower section ensure a distinctly masculine aura. Large, round foglamps with chrome surrounds are now positioned further outwards, enhancing the impression of width. The hot air from the integral engine oil cooler is vented via side outlets in the front apron. The specific AMG bodystyling also includes AMG side skirts, the muscular AMG rear apron with a black insert and the AMG spoiler lip.

AMG Eight-cylinder Engine

The striking bonnet with its characteristic longitudinal fins conceals the 5.5-liter AMG eight-cylinder engine, which has an output of 360 bhp and develops 376 lb-ft of torque – figures which remain unrivalled in this segment. Enormous torque, immediate responsiveness and the typical AMG V8 sound characterize the driving experience, together with outstanding performance: the two-seater accelerates from zero to 60 mph in just 4.7 seconds, reaches the 124 mph mark in 17.5 seconds and has a top speed (electronically limited) of 155 mph. Power is transferred by the AMG SPEEDSHIFT 7G-TRONIC transmission with steering wheel gearshift paddles, which now ensures even greater agility: gearchanges in the "S" (Sport) and "M" (Manual) driving modes are around ten percent faster than before. This is not only thanks to the new components in the seven-speed automatic transmission, but also to the new engine and transmission management, which also ensures that the gearshifts are smoother.

Functional Interior

In the functional and sporty interior of the SLK 55 AMG, the new AMG ergonomic sports steering wheel with its three-spoke design gives a visual hint of the direct steering feature. The grip area is specially shaped and lined with perforated leather, while the vertical spoke is embellished by a silver-colored insert. Two aluminum AMG shift paddles allow manual gear selection.

The AMG instrument cluster, silver/red needles and AMG lettering also has a new look, and the new graphics ensure that vehicle speed and rpm are even more easily legible. In "M" mode, the AMG main menu is able to display the currently selected gear including an upshift recommendation, as well as the engine oil temperature, the battery voltage or the RACETIMER. The AMG sports seats with their special upholstery layout feature pronounced side bolsters for improved lateral support when cornering at speed; Alcantara inserts in the shoulder areas improve this lateral support even further. Fine nappa leather upholstery is part of the standard appointments of the SLK 55 AMG. It is available in a choice of four attractive colours, with a stylish combination of black/gullwing red as a new entrant to the range.

Performance Package

The AMG performance package is available for the SLK 55 AMG on request. This package developed by the AMG PERFORMANCE STUDIO incorporates even higher-performance components. The result is an ultra-exciting driving experience for sports car enthusiasts who sometimes like to put their AMG model through its paces on the racetrack.

Base Price: 2008 Mercedes-Benz SLK 55 AMG Black Edition - 92,500 € (last update: 8/28/2007)

The new Black Series from Mercedes-Benz is an even more driver-focused variant of the V8-powered SLK 55 AMG Roadster, using motorsport-inspired technology to deliver scintillating performance and enhanced driving dynamics.

Output from the 5.5-liter AMG engine is boosted from 360 bhp to 400 bhp and 45 kg has been shaved off the kerbweight through the use of lightweight components including a new fixed hard top. As a result, the 0 to 60 mph dash drops to 4.3 seconds, while 125 mph is, where permitted, clocked up in just 15.5 seconds – a full two seconds quicker. Top speed is no longer restricted to 155 mph, and the car can reach 173 mph.

The exclusive nature of the SLK 55 AMG Black Series is signaled by even more muscular front wings made from ultra-light carbon fiber-reinforced plastic (CRP) and a restyled AMG front skirt with carbon fiber inlays. Large air intakes and side air outlets ensure a sufficient flow of air to the enlarged engine oil cooler and new transmission and steering oil coolers.

The SLK’s standard vario roof with its hydraulic closing mechanism has been replaced with a purposeful fixed hard top which has a central section in black carbon-fiber CRP. It means that not only is the car’s centre of gravity lower, there is also a significant weight loss – it now tips the scales over seven stones lighter than the standard car, at 3295 lbs.

The motorsport theme continues inside: two specially developed AMG sports bucket seats without side airbags offer superb lateral support and are trimmed in a black pearl velour complete with silver AMG logos. They are complemented by a leather and Alcantara trimmed steering wheel derived from that used in the FIA Formula One World Championship Official Safety Car, and lightweight AMG carbon fiber internal door centre panels.

The V8’s power output of 400 bhp at 5,750 rpm compares with the standard AMG model’s 360 bhp, produced at the same engine speed. It develops an even more muscular 384 lb-ft of torque at 3,750 rpm. Key enhancements include a modified air intake, an AMG sports air filter and a newly-developed exhaust system. Power continues to be fed through an AMG Speedshift 7G-TRONIC transmission with a manual drive program and steering wheel-mounted aluminum shift paddles.

Naturally the chassis has been modified to match the increased performance capability of this special series SLK 55 AMG. Racetrack-optimized, AMG height-adjustable torsion suspension, including adjustable dampers permits even more impressive cornering ability. 19 inch ultra-light AMG forged alloy wheels with 235/35 ZR19 (front) and 265/30 ZR19 (rear) Pirelli P Zero Nero tires replace the 18 inch items of the standard car. Greater body rigidity is provided by a brace across the engine bay, and for those looking for even sportier handling, there’s a limited slip differential available, priced at 3,475 euros in Europe.

There is stopping power to match the performance and the front wheels continue to feature composite technology to minimize braking distances, optimize sensitivity and ensure high resistance to fading. The composite brake discs are now 360 mm in diameter, up from 340 mm. The 330 mm internally ventilated and perforated brake discs at the rear are retained.

The SLK 55 AMG Black Series may possess a level of driving dynamics orientated towards track use, but it is also a car eminently suited to everyday driving and provides the safety, durability and quality that come as standard across the Mercedes-Benz range. The Black Series is also offered with three additional AMG packages for even greater exclusivity: an AMG Leather package includes leather seats, dash, centre console, centre armrest, door panels and doorbags, and anti-roll bars for 6,310 euros. An AMG Interior Carbon Fiber package includes carbon fiber instrument cluster covers, steering wheel multi-function button covers, gearshift lever and door sill panels for 2,630 euros. An AMG Exterior Carbon Fiber package has carbon fiber front grille inserts, external mirror covers and rear boot spoiler trim, for 4,325 euros.

The SLK 55 AMG Black Series is priced at 92,500 euros and is available by special order from Mercedes-Benz Retailers in Europe now. Prices and availability in the US is not yet confirmed.
