Automobile fascination paired with spectacular race car design – that is the new Mercedes-Benz SLS AMG GT3. The racing version of the 2011 SLS AMG has been conceived as a customer sport vehicle for participation in race series based on FIA GT3 regulations. Meticulous lightweight construction and optimized chassis, brakes and aerodynamics deliver uncompromising dynamics. The extra special SLS AMG will make its race track debut in 2011.

Thoroughbred motorsport technology for the race track

Automobile fascination paired with spectacular race car design – that is the new Mercedes-Benz SLS AMG GT3. The racing version of the SLS AMG has been conceived as a customer sport vehicle for participation in race series based on FIA GT3 regulations. Meticulous lightweight construction and optimized chassis, brakes and aerodynamics deliver uncompromising dynamics. The extra special SLS AMG will make its race track debut in 2011.

The clean design and breathtaking form of the SLS AMG have been effectively accentuated by targeted modifications to the bodyshell. The new components, made largely from lightweight carbon fiber offer a clear indication of extraordinary race track performance and extensive aerodynamic development work.

From the front, the GT3 race car boasts a new front skirt with enlarged air intakes. The wide opening beneath the characteristic radiator grille bearing the large Mercedes star and the wing-shaped horizontal fins supplies air to the engine oil cooler and brake discs. The same function is served by the two intakes below the vertical bi-xenon headlamps. Downforce on the front axle is provided courtesy of four externally mounted side flics, as well as a carbon front splitter; it runs directly into the smooth underbody panel, which connects to the rear diffuser.

The hood features a central opening for the extraction of heat from the engine, while side openings in the front fenders facilitate air flow through the wheel arches. Weight optimization measures include the application of extremely lightweight polycarbonate for the side and rear windows and, if desired, for the front windshield as well.

The fenders have been widened front and rear to accommodate the large racing tires. With a breadth of 78.3 inches, the GT3 bodyshell is a good 2 inches wider than the series production SLS AMG. The new sills feature openings for cooling the rear brakes, with the smooth underbody visible along the underside of the sills. The B-pillar houses the standardized fuel tank adapter for the rapid refueling system. The 31.7 gallon fuel tank is located centrally behind the driver.

Wide rear carbon spoiler

The rear view of the SLS AMG GT3 is dominated by its imposing width. Above the rear hatch sits a wide carbon fiber spoiler; it is extensively adjustable and facilitates perfect setup to suit individual race track characteristics. The new rear skirt accommodates two openings for extracting air from the rear wheel arches. A further visual highlight is the rear carbon fiber diffuser; it rises smoothly from the rear axle area as a continuation of the smooth underbody, its form adding to the downforce. The overall aerodynamic concept of the SLS AMG GT3 was analyzed and defined through extensive wind tunnel and race track testing.

The black exhaust end pipes deliver a fascinating and, at the same time, characteristic AMG eight-cylinder sound. The regulation rain lamp is integrated into the rear hatch – it must be switched on by the driver in poor weather conditions.

Close to series production AMG 6.3 liter V8 engine

As defined in the FIA GT3 regulations, the AMG 6.3 liter V8 engine is virtually identical to that of the series production vehicle. Thanks to its low weight, the acceleration figures for the GT3 – 3.7 seconds for the sprint from 0 to 60 mph – are considerably below the already excellent figures for the series production vehicle. Depending on gear ratio, the top speed is more than 186 mph.

The AMG 6.3 liter V8 engine uses dry sump lubrication in the racing vehicle, too. The application of a suction and pressure pump, as well as an external oil tank means that the conventional oil sump can be omitted. This technology ensures reliable lubrication of the engine under high lateral acceleration, of the kind usually experienced on the race track.

Dry sump lubrication also facilitates a low mounting position for the V8 power unit – one of the key technological highlights of the SLS AMG. The solution – installing the eight-cylinder as low as possible and as a front mid engine behind the front axle, combined with a transaxle transmission layout – results in excellent weight distribution.

Six-speed racing transmission with sequential shift

In contrast to the series production vehicle, the SLS AMG GT3 is equipped with a sixspeed racing transmission with sequential shift. Thanks to its compact construction, the race-tested transmission offers considerable packaging benefits – ultimately, the GT3 version has less ground clearance than the series production vehicle. The driver shifts gear using two shift paddles on the steering wheel. The transmission is mounted directly on the rear axle and connected to the V8 engine via a torque tube, which has a very high degree of flexural and torsional stiffness. This delivers considerable benefits when it comes to dynamics, as this sophisticated solution enables the entire driveline to be laid out with significantly less play. Alongside the traction control, a multi-plate locking differential integrated into the transmission delivers outstanding acceleration characteristics. Inside the torque tube, a drive shaft rotates at engine speed. As in the series production model, and in the Mercedes-Benz C-Class DTM touring car, the shaft is made from carbon fiber.

With its long wheelbase, low center of gravity and wide track, the SLS AMG vehicleconcept was predestined for the race track – its strengths include precise turn-in characteristics, first-class agility, low inertia under sudden changes of direction and a high cornering limit.

It required only minimal modification for perfect race track performance. The lightweight aluminum chassis with double wishbone suspension at all four corners has modified kinematics to take into account the lower vehicle height. The array of adjustability options facilitates optimal modification to suit individual race track characteristics and varying weather conditions. As well as the ability to vary the spring and damper setup, there is also the freedom to adjust track and camber, vehicle height and the stabilizers on the front and rear axles.

Like the series production SLS AMG, the GT3 version is also equipped with rack and pinion steering with speed dependent power assistance. The more direct input ratio facilitates even greater handling agility on the race track.

AMG race braking system using composite technology

Shortest stopping distances, highest stability and optimal control are guaranteed by the AMG race braking system. All four corners feature brake discs in motorsport-tested composite technology. Gray cast iron axial and radial floating discs are fixed to an aluminum hat via stainless steel composite elements. This sophisticated technology enables perfect heat dissipation and thus reliable stability. The SLS AMG GT3 is also equipped with precisely calculated cooling channels – openings in the front skirt and ahead of the rear wheels direct cool airflow over the brake discs. All four brake discs are ventilated, slotted and drilled. Six-pot fixed calipers on the front axle and four-pot fixed calipers at the rear, finished in anthracite with the AMG logo in white, provide plenty of brake pad surface. An anti-lock brake system with special race track settings is fitted as standard. Due to space restrictions, the AMG high-performance ceramic composite brake system, available as an option on the series production vehicle, is not compatible with the 18-inch wheels prescribed by FIA regulations.

The AMG center-locking alloy wheels – 12×18 inches front and 13×18 inches rear – are fitted with racing tires in formats 11.3 × 26.9 inches (front) and 12.4 × 27.9 inches (rear). Depending on the application, the tires are available as profile-free slicks, intermediates or wet weather tires. The classic multi-spoke design aids ventilation of the braking system. Fast pit stops and wheels changes are ensured by the pneumatic lift system integrated into the underbody. Four pneumatic rams raise the GT3 race car by around 7.5 inches, enabling the pit crew to change the racing tires in double quick time.

Interior with racing bucket seat and race steering wheel

On opening the gullwing doors, the SLS AMG GT3 displays a functional interior with a distinctly race car feel. The driver sits in a racing bucket seat fitted with a six-point harness and the HANS system (Head and Neck Support) that fixes the helmet in place in the event of an accident, thus minimizing the risk of injury. Additional safety comes courtesy of the steel roll cage, which also serves to further stiffen the aluminum spaceframe.

A steering wheel with a diameter of 13 inches facilitates perfect vehicle control. Because it is open at the top, the driver always has a perfect view of the central display, which provides all relevant information such as road speed, engine speed, operating temperatures, lap times and gear selection. The steering wheel is fitted with a quickrelease mechanism that makes entering and exiting the vehicle considerably easier. The switches on the steering wheel hub enable the driver to activate additional functions such as the pit radio, headlamp flasher and the drink supply. Further operating elements are mounted on the center console and include the start/stop function for the AMG V8 engine, the traction control, reverse gear and – just in case – the integrated fire extinguisher. The control for adjusting brake balance is located on the torque tube tunnel.

The close relationship between the GT3 and its series production sibling is demonstrated by the instrument cluster, with its powerfully taut wing profile providing visual breadth. Integrated into the dash are the highly distinctive air vents galvanized in “Silver Shadow” and with adjustable cross-shaped nozzles – their form evocative of a jet engine.

Deliveries of customer vehicles to start early 2011

The new SLS AMG GT3 has been developed in accordance with FIA GT3 regulations and is entitled to participate in all GT3 race series – including the popular 24-hour races in Spa-Francorchamps, Belgium, and on the Nürburgring in Germany. Interested customers can order the vehicle starting in autumn 2010, with delivery scheduled prior to the start of the 2011 racing season. Homologation will be completed in March 2011.

Mercedes-Benz Unveils 2011 SL550 Night Edition

Making its auto show debut in New York is the limited-edition 2011 SL550 Night Edition. Based on the iconic SL-Class coupe/roadster, the highlight of the SL550 Night Edition is its matte-finish designo magno night black paint and Black premium leather interior. Limited to just 100 units, this exclusive model will be available in U.S. showrooms in early 2010.

The special designo magno night black paint finish — specially developed exclusively for the SL550 Night Edition — works particularly well with the dramatic design of the SL-Class. The Night Edition rolls on 19-inch AMG five-spoke light-alloy wheels in a twotone, high-gloss finish, silver-painted front brake calipers with “Mercedes-Benz” script and darkened headlamps/tail lights help distinguish the exclusive status of the SL550 Night Edition.

The interior features a striking contrast of dark Black premium leather and bright chrome trim, with numerous fine details. The newly-designed seats have arrow-shaped seams and silver-colored contrasting features, while the sports steering wheel, shift lever and roof lining are trimmed in black. The trim strip of the wind-deflector has a high-gloss finish complimented by the silver-colored vents of the AIRSCARF® system, which bathes the driver in warm air when the convertible top is down during cooler weather.

Mercedes-Benz SL Roadster Sets the Standard

A direct descendant of the legendary 300SL “Gullwing” of the 1950s, the current SL roadster line-up features the V8-powered SL550 (382 horsepower, 391 lb.-ft. of torque) and the V12-powered SL600 (510 hp, 612 lb.-ft.) as well as the high-performance V8-powered SL63 AMG (518 hp, 465 lb.-ft.) and the V12-powered SL65 AMG (604 hp, 738lb.-ft.).

Mercedes-Benz performed a comprehensive exterior redesign on the iconic SL roadster, which features dramatic styling with fenders that incorporate sharp, angular headlights and modified gill-type air outlets behind the front wheels. A front hood with two power domes and a bold single-lamella grille emphasize the width of the body and make a symbolic visual connection to the famous 1954 300SL, while larger side mirrors reveal built-in arrow-shaped turn signals.

At the rear, the SL looks more aggressive than ever, with an air diffuser in the bumper that adds a motorsports touch, as well as trapezoidal exhaust tips that emphasize its width and suggest all the power on tap. The cockpit reveals a three-spoke multifunction steering wheel and an instrument cluster with eye-catching red tachometer and speedometer needles that swing to the max position and back to zero whenever the ignition is turned on.

AIRSCARF Around the Head and Neck

All Mercedes-Benz SL roadsters are available with AIRSCARF, an innovative feature that can extend the open-air driving season into the cooler months. Another first from Mercedes-Benz, 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 cooler temperatures. AIRSCARF uses a heating element made primarily of barium titanate, which heats up in a matter of seconds when electrical current is applied.

Its electrical resistance jumps once it’s heated, reducing the power needed – engineers call this balance “Positive Temperature Coefficient” or PTC for short. The PTC heater is only a few inches in size, allowing it to hide inside the SL seatback. Aluminum fins on the heater help transfer the heat to the air, and a small fan pushes the heated air through the vents in the head restraint. Standard on the SL600 and SL65 AMG models (and optional on the SL550 and SL63 AMG), the AIRSCARF neck-level heating system even compensates for changes in air temperature and vehicle speed.

An electronic control module monitors data from inside and outside temperature sensors as well as the speedometer. AIRSCARF automatically adjusts fan speed based on this information, and a three-speed switch can override the automatic settings.

SL63 AMG Features AMG-Designed V8

The SL63 AMG has one of the most powerful naturally aspirated production V8s ever, boasting a wealth of exciting features derived from AMG’s highly successful racing efforts. Built almost completely from a high-strength silicon-aluminum alloy, the 518 hp engine features four valves per cylinder, variable valve timing, bucket-type cam followers (rather than rocker arms), and a variable intake manifold.

Laguna Seca (USA) – Automotive fascination and high-tech at the highest level: the new Mercedes-Benz SLS AMG, which is due to be launched in spring 2010. This Gullwing model captivates with a purist design, intelligent lightweight construction and superior handling dynamics, and is bound to cause a sensation in the super sports car segment. The new SLS AMG is nothing short of a masterpiece by Mercedes-AMG GmbH. As the first independently developed vehicle, the super sports car is the highlight in the company’s more than 40-year history. It not only takes AMG, the performance brand within Mercedes-Benz Cars, into a new era, but also demonstrates development expertise of the very highest order.

The new super sports car from Mercedes-Benz and AMG makes for an alluring proposition with its unrivalled technology package: aluminum spaceframe body with Gullwing doors, AMG 6.3-liter V8 front-mid-engine developing 420 kW/ 571 hp peak output, 650 Nm of torque and dry sump lubrication, seven-speed double-declutch transmission in a transaxle configuration, sports suspension with aluminum double wishbones and a curb weight of 1620 kilograms based on the DIN standard – this superlative combination guarantees driving dynamics of the highest order.  … Photo Gallery:

The front/rear weight distribution of 47 to 53 percent and the vehicle’s low centre of gravity are testimony to the uncompromising sports car concept. The ‘Gullwing’ accelerates from 0 to 100 km/h in 3.8 seconds, before going on to a top speed of 317 km/h (electronically limited). The fuel consumption of 13.2 litres per 100 kilometers (combined) puts it at the front of the competitive lineup.

Design: purist, distinctive and passionate

The purist design of the new Mercedes-Benz SLS AMG captivates by virtue of its passionate sportiness, and its reinterpretation of the Mercedes-Benz 300 SL’s breathtaking design lines. The stylistic highlights are the striking gullwing doors, which lend an incomparable charisma to the SLS AMG. The long bonnet, the low greenhouse positioned well to the rear and the short rear end with its extendable rear aerofoil stand for dynamism, as do the long wheelbase, the wide track and large 19 and 20-inch wheels. It is not only the gullwing doors that are reminiscent of the Mercedes-Benz 300 SL, as the wide radiator grille with its large Mercedes star, the wing-shaped cross fin and the fins on the bonnet and flanks also hark back to the legendary sports car of the 1950s.

Eye catching features of the side view include the accented wheel arches and the pronounced shoulder line, which extends from the front to the rear end like a taut muscle. Dynamism and power are also communicated by the rear view of the SLS AMG: the gentle slope of the boot lid with the automatically extending aerofoil accentuates the impression of width, as do the flat LED tail lights.

Interior with a touch of aircraft engineering

Mercedes-Benz designers took their inspiration from the aviation world when
designing the interior. The stylistic center piece is the dashboard, which ensures a visual impression of breadth with its muscular, wing-like profile. The four air vents with adjustable cruciform nozzles are prominently integrated into the dashboard – their shape is reminiscent of a jet engine. The design theme of an aircraft cockpit is also reflected in the long centre console of matt-finished, solid metal. Features integrated into this include the AMGDRIVE UNIT, which enables the driver of the SLS AMG to choose a personal vehicle setup. The AMGSPEEDSHIFT DCT 7-speed sports transmission is operated by the E-SELECT lever, which resembles the thrust control of a jet aircraft. Despite the low seating position typical of a sports car, the wide-opening gullwing doors allow easy access and egress. They require less opening space than conventional coupé doors, and can be fully opened in a standard-size garage.

Aluminum spaceframe for lightweight design and high strength

The SLS also breaks the mould when it comes to the body concept: for the first time, Mercedes-Benz and AMG are presenting a car with an aluminum chassis and body. Compared with the traditional steel design this results in a significant weight saving, as is clearly illustrated by the DIN curb weight of 1620 kilograms.

The newly developed bodyshell consists of an aluminum spaceframe. This exclusive design combines intelligent lightweight design with outstanding strength – thus delivering superlative driving dynamics. Lightweight aluminum sections connect the frame nodes to form a sturdy structure. The large, low-set cross-sections of these aluminum sections ensure high strength, and ensure the necessary, direct transfer of drive, braking and suspension forces. The structure prevents unwanted flexibility; the vehicle responds rigidly, directly and with practically no torsion.

45 percent of the intelligent, weight-optimized aluminum spaceframe is made
from aluminum sections, 31 percent from sheet aluminum, 20 percent from cast aluminum and 4 percent from steel. Maximum occupant safety requires the use of ultra-high-strength, heat-formed steel in the A-pillars. The bodyshell weighs 241 kilograms – an absolute benchmark in the super sports car segment in relation to the peak output of 420 kW/571 hp. With a DIN kerb weight of 1620 kilograms, the power-to-weight ratio is an extremely favorable 2.84 kilograms per hp.

Low centre of gravity and transverse reinforcing struts for superb
dynamism

The entire vehicle concept has been designed to achieve a centre of gravity that is as low as possible. This applies both to the low connection of the powertrain and axles as well as to the arrangement of the rigidity-related bodyshell structure. Examples include the rigid flexural and torque connections between the front and rear sections and the safety passenger cell, which have been realized using force paths that are consistently as low as possible. This results not only in a low centre of gravity, but also in a harmonious and therefore efficient force path in the vehicle structure.

Passive safety at a high level

The aluminum spaceframe provides the basis for outstanding passive safety. The extensive safety features include three-point seat belts with belt tensioners and belt force limiters, and up to eight airbags: adaptive front airbags for the driver and passenger, a knee bag for each, two seat-integrated sidebags and two window bags deploying from the waistlines of the gullwing doors.

Fine-tuned AMG 6.3-liter V8 engine developing 420 kW/571 hp

A powerful eight-cylinder Mercedes-AMG engine forms the heart of the new SLS. The fine-tuned 6.3-liter V8 engine develops 420 kW/571 hp at 6800 rpm, making the SLS AMG one of the most powerful sports cars in its segment. A power-to-weight ratio of 2.84 kg/hp comes courtesy of the low vehicle weight. The naturally aspirated engine delivers its maximum torque of 650 Nm at 4750 rpm. The SLS accelerates from 0 to 100 km/h in 3.8 seconds, and has an electronically limited top speed of 317 km/h. Bearing the internal designation M 159, the high-revving V8 engine with its displacement of 6208 cubic centimeters has been thoroughly reengineered compared to the basic M 156 engine, and boasts all the hallmarks of powerful racing engines.

The principal measures in increasing output include the all-new intake system, the reworked valve train and camshafts, the use of flow-optimized tubular steel headers and the de-throttling of the exhaust system. This results in much better cylinder charging, which feeds through into an increase in output by almost nine percent – 34 kW/46 hp. The eight-cylinder engine responds swiftly to movements of the accelerator pedal, demonstrating much more pronounced high-revving flexibility across the entire rev range. The switch to dry sump lubrication also translates into a much lower installed engine position. And lowering the vehicle’s centre of gravity has also paved the way for high lateral acceleration and exhilarating driving dynamics.

Perfect synthesis of lightweight design and strength

The use of high-strength components compensates for the increased engine loads associated with the higher output. Forged pistons, a reinforced crankshaft bearing, optimized crankcase structure, along with improved lubrication thanks to a demand-controlled, high-performance oil pump ensure optimum durability. Despite these higher loads, the engine weight for the M 159 has been further reduced. The forged pistons as oscillating masses play a particularly valuable role in this respect, resulting in a curb weight of 205 kilograms and, in turn, a power-to-weight ratio of 0.36 kg/hp – an unrivalled figure compared with the competition. Sophisticated catalytic converter technology enables current and future exhaust emission standards such as EU 5, LEV 2 and ULEV to be met.

Enables demanding fuel consumption targets to be met

Despite its uncompromisingly sporty character, very ambitious fuel consumption targets have been met. The SLS AMG consumes 13.2 liters per 100 kilometers (combined, provisional figure), earning it a place at the top of the competitive ranking. Efficiency-enhancing measures include the familiar AMG-exclusive, friction-optimized twin-wire arc-sprayed coating on the cylinder walls as well as the on-demand, map-optimized oil supply and intelligent generator management: during the engine’s overrun phases and braking, kinetic energy is used to charge the battery, rather than being wasted by simply generating heat. Conversely, the generator is switched to no-load operation during acceleration, thus reducing the load on the engine.

Double-declutch transmission with transaxle configuration and torque tube

The AMG 6.3-liter V8 engine delivers its abundant power to the rear axle via an ultra-light carbon-fiber driveshaft – similar to the setup used in the DTM C‑Class racing touring car. The double-declutch transmission is mounted at the rear (transaxle principle), and connected to the engine housing via a torque tube. A carbon-fiber shaft rotates at engine speed in the torque tube. The advantages of this sophisticated solution lie in the rigid link between the engine and transmission and, in turn, the optimum support for the forces and torque generated.

The AMG SPEEDSHIFT DCT 7-speed sports transmission boasts fast gear changes with virtually no loss of tractive force – in as little as 100 milliseconds. The driver has a choice of four different driving modes: “C” (Controlled Efficiency), “S” (Sport), “S+” (Sport plus) or “M” (Manual). In the Sport, Sport plus and Manual modes the automatic double-declutching function is active; all the modes can be selected conveniently via the rotary control in the AMG DRIVE UNIT. The RACE START function provides optimum traction — as does the mechanical differential lock, which is integrated into the compact transmission housing.

Sophisticated suspension layout with double-wishbone axles

The chosen solution with a front-mid-engine plus transaxle configuration ensures an ideal front/rear weight distribution of 47 to 53 percent. Mounting the engine behind the front axle has created the ideal conditions for consummate driving dynamics with precise steering, first-class agility, low inertia with spontaneous directional changes and outstanding traction. All four wheels are located on double wishbones with a track rod, a technology that has proven itself in motor racing right through to Formula 1. With a double-wishbone axle, the wheel location and suspension functions remain separate; the spring/damper struts are supported on the lower wishbone. The double-wishbone concept with its high camber and track rigidity positively locates the wheel with minimal elastic movements, providing the driver with an optimum sense of road contact when driving at the limits.

Wishbones, steering knuckles and hub carriers at the front and rear are made entirely from forged aluminum – substantially reducing the un-sprung masses; this configuration also notably improves the suspension response. The long wheelbase of 2680 millimeters not only results in outstanding straight-line stability but also low wheel load shifts, significantly reducing the vehicle’s tendency to dive and squat when braking and accelerating. The broad track width – front 1682, rear 1653 millimeters – ensures lower shifts in the wheel loads from the inner to the outer wheel when cornering, enabling the tires to retain more grip.

Direct steering, differential lock and 3-stage ESP®

The rack-and-pinion steering gear provides a consistently direct steering feel with a constant mechanical ratio of 13.6:1, in tune with the high expectations placed on a super sports car. The power steering provides speed-sensitive assistance and improves feedback for the driver as the road speed increases: an indispensable factor for high-speed straight-line driving. Mounting the steering gear in front of the engine on the integral subframe enables the engine to be set down very low. The Gullwing model comes with 3-stage ESP® as standard, and the driver can choose the three “ESP ON”, “ESP SPORT” and “ESP OFF” modes at the touch of a button. In “ESP OFF” mode too, operating the brake pedal restores all the normal ESP® functions.

Acceleration skid is controlled in all three ESP® modes. If one of the drive wheels starts to spin, specific brake pressure is applied to improve traction significantly – especially in conjunction with the standard-fit mechanical multi-disc limited-slip differential. This means that the engine power is transferred to the road even more effectively when driving in a particularly dynamic style.

AMG ceramic composite high-performance braking system available as an option

The AMG high-performance braking system with composite brake discs at the front ensures extremely short stopping distances even under high loads. The newly developed, optional ceramic composite brakes with even larger brake discs guarantee even better braking performance. The ceramic brake discs perform reliably at even higher operating temperatures thanks to their greater hardness, all combined with an impressive weight reduction of around 40 percent. Reducing the un-sprung masses has further improved both comfort and grip, and the reduced rotating masses at the front axle ensure a more direct steering response.

Lightweight construction was also key when it came to the wheels: weight-optimized AMG light-alloy wheels – 9.5 x 19 inch (front) and 11.0 x 20 inch (rear) – based on the innovative flow-forming principle reduce the un-sprung masses while improving driving dynamics and suspension comfort. In addition to the standard-fit AMG 7-spoke light-alloy wheels, 5-twin-spoke wheels and weight-optimized 10-spoke forged wheels are available as an option. 265/35 R 19 (front) and 295/30 R 20 (rear) tires developed exclusively for the SLS AMG ensure optimum performance. A tire pressure monitoring system is fitted as standard to permanently monitor tire pressure in all four wheels; individual tires are shown on the display.

The SLS AMG as a masterpiece in AMG‘s more than 40-year history

The new SLS AMG is a true masterpiece on the part of Mercedes-AMGGmbH.
As the first independently developed car, the super sports car is the highlight of the company’s more than 40-year history. With this car AMG, the performance brand within Mercedes-Benz Cars, is not only entering a new era, but also demonstrating development expertise of the highest order.

AMG was established in 1967 by Hans Werner Aufrecht and Erhard Melcher, and is considered a pioneer in the field of vehicle tuning for motorsports. Following the cooperation agreement concluded in 1990 with Daimler-Benz AG, the company was gradually incorporated into what at the time was DaimlerChrysler AG in 1999. On 1 January 2005, DaimlerChrysler AG acquired 100 percent of the shares. Today Mercedes-AMG GmbH is a vehicle manufacturer in its own right, and AMG is the performance brand within Mercedes-Benz Cars. This subsidiary of Daimler AG specializes in unique, high-performance vehicles; its sporty saloons, SUVs, coupés, cabriolets, roadsters and specially built one-off models constitute a product portfolio which meets its customers’ every wish. The product range encompasses a total of 16 AMG high-performance models with outputs ranging from 265 kW/360 hp to 450 kW/612 hp.

Mercedes-AMG has overall responsibility for developing the design, aerodynamics, interior as well as the powertrain, engine, suspension, brakes and electronics – right up to granting final approval for production of the complete AMG vehicle.

Sales of the SLS AMG in Germany will commence on 16 November 2009

The SLS AMG can be ordered from Mercedes-Benz own-retail outlets and dealerships in Germany from 16 November 2009. The purchase price is 177,310 EUR (incl. 19 % VAT); the market launch commences in spring 2010.

More than a quarter of a million readers took part, and voted the new Mercedes-Benz SLS AMG the world’s best super sports car by a wide margin. Accordingly “Bild am Sonntag”, “Auto Bild” and 25 associated European publications awarded the new Gullwing model the “Golden Steering Wheel” – one of the most important automotive awards in Europe. This coveted award was officially presented to Dr. Dieter Zetsche, Chairman of Daimler AG and CEO of Mercedes-Benz Cars, in Berlin yesterday evening.

Eleven super sports cars competed in the large-scale reader’s vote for the “Golden Steering Wheel” award, which “Bild am Sonntag” and the motoring magazine “Auto Bild” organized on a Europe-wide basis for the first time this year. Almost one third of all votes were cast in favor of the new Mercedes-Benz SLS AMG, which therefore headed the readers’ popularity list in the super sports car category by a wide margin over the runner-up.

This result not only acknowledged the unique aura and design of the new Mercedes-Benz SLS AMG, whose gullwing doors evoke memories of the legendary 300 SL “Gullwing” sports car of the 1950s, but also its technical sophistication. The super sports car excels with its uncompromising lightweight construction, superior driving dynamics and exemplary safety. These attributes are ensured by a unique technology package consisting of a lightweight aluminum spaceframe body with gullwing doors, the AMG 6.3-liter V8 front-mid-engine with dry sump lubrication, a peak output of 420 kW/571 hp and 650 newton meters of torque, a seven-speed double-declutch transmission in a transaxle arrangement and a sports suspension with aluminum double wishbones. This combination guarantees dynamic performance at the very highest level. The ideal weight distribution of 47:53 percent between the front and rear axles, as well as the low centre of gravity, further enhance this thoroughbred sports car design. The SLS AMG accelerates from zero to 100 km/h in 3.8 seconds, and has a top speed of 317 km/h.

The SLS AMG can be ordered from Mercedes-Benz own-retail outlets and dealerships in Germany from 16 November 2009. The purchase price is 177,310 EUR (incl. 19 % VAT); the market launch commences in spring 2010.

The new Gullwing model is continuing a fine tradition in winning the “Golden Steering Wheel” award: with a total of 18 victories to date, Mercedes-Benz is among the most successful car brands in the competition for the “Golden Steering Wheel”.

The new super sports car from Mercedes-Benz and AMG makes for an alluring proposition with its unrivalled technology package: aluminum spaceframe body with gullwing doors, AMG 6.3-liter V8 front-mid engine developing 420 kW/ 571 hp peak output, 650 Nm of torque and dry sump lubrication, seven-speed dual-clutch transmission in a transaxle configuration, sports suspension with aluminum double wishbones and a curb weight of 1620 kilograms based on the DINstandard – this superlative combination guarantees driving dynamics of the highest order.

The ideal front/rear weight distribution of 47 to 53 percent and the vehicle’s low center of gravity are testimony to the uncompromising sports car concept. The ‘Gullwing’ accelerates from 0 to 100 km/h in 3.8 seconds, before going on to a top speed of 317 km/h (electronically limited). The fuel consumption of 13.2 liters per 100 kilometers (combined) puts it at the front of the competitive field (all figures provisional).

“Mercedes-Benz is presenting an exhilarating super sports car in the guise of the new SLS AMG, which is bound to set the pulses of all car enthusiasts racing that extra bit faster. The brands Mercedes-Benz and AMG have joined forces to create the SLS AMG– which is set to become one of the most alluring sports cars of all time”, says Dr. Dieter Zetsche, Chairman of the Board of Management of Daimler AG and Head of Mercedes-Benz Cars.

“Our customers will experience with the SLS AMG the expertise of Mercedes-AMG, built up over 40 years of motor racing. The unrivalled technology package delivers outstanding driving dynamics coupled with moderate fuel consumption figures – part and parcel of the modern-day AMG,” says Volker Mornhinweg, Chairman of Mercedes-AMG GmbH.

“The styling of the new Mercedes-Benz SLS AMG is not only very special because of the exclusive gullwing doors. Our aspiration is to utilize this interpretation to create the classic of tomorrow and roll out the most alluring sports car of the 21st century. Our aim is also to create a new design icon, which shapes the incomparable legend of our brand, alongside Mercedes models like the CLS or the SL. At the same time, the new SLS paves the way for the design philosophy of forthcoming Mercedes-Benz sports cars”, says Gorden Wagener, Head of Design at Mercedes-Benz Cars.

Design: purist, distinctive and passionate

The distinctive styling of the new Mercedes-Benz SLS AMG enthralls with its passionate sportiness and reinterprets the breathtaking lines of the Mercedes-Benz 300 SL – one of the outstanding design icons of the Mercedes-Benz brand. With its purist design the new SLS AMG reflects the philosophy of contemporary sports car engineering: the bonnet which measures just under two meters, the low greenhouse positioned well to the rear and the short rear-end with an extendable aerofoil are just as powerful a reminder of the superlative dynamism as the long wheelbase, the wide track and the large wheels. The short overhangs feed through into the proportions, just as does the design of the super sports car with its low-slung front-mid engine set well back and dual-clutch transmission in transaxle configuration. An undoubted styling highlight comes courtesy of the gullwing doors which lend the SLS AMG its incomparable charisma – making a unique statement in this vehicle segment.

The gullwing doors are not alone in rekindling memories of the Mercedes-Benz 300 SL; the hallmark wide radiator grille with the large Mercedes star and the wing-shaped cross fins are a throwback to the front-end of the sports car legend. The three-dimensional, sculptured front-end with its low-set, swept-back front apron set well into the sides lends the ‘Gullwing’ its powerful stance on the road. Six large cooling air intakes and the vertically arranged headlamps set well to the outside with their alluring inner ambience provide a dominant aura: the central bi-xenon low-beam headlamp with its metallic wing section is framed at the top by two LED indicators and the LED daytime driving lights at the bottom.

Influences from aircraft construction

Allusions to aircraft construction come courtesy of the prominent Mercedes star, whose tubular section is reminiscent of the air intake on a jet engine when viewed from the side, as well as the long bonnet: as the eye is drawn forward, so the observer becomes more aware of the curve. The design of the four fins with their Silver Shadow finish that adorn the two air outlet grilles on the end of the bonnet create the same visual impression. These aircraft-style lines also visually accelerate the air that flows past – and make the SLS AMG appear extremely dynamic even while stationary.

The fins on the bonnet are taken up on the vehicle flanks: the connoisseur also discovers here a hallmark styling feature of the 300 SL. The “6.3″ lettering placed between the fins provides a clear reference to the high-displacement naturally aspirated V8 engine. The side air outlet feeds through into a stylistically prominent feature line, which together with the convex flanks and the exhilarating surface treatment, combines aesthetics with power. The compact passenger compartment proves as alluring as it is unmistakable. With its high beltline, low side windows and steeply angled windscreen it comes across as a kind of visor. The forward angled B-pillar with its stylish flowing sweep to the rear window exudes pure dynamism.

Side view dominated by muscle and shoulder

Seen from the side, the eye is drawn to the prominent vehicle shoulder of the SLS, which stretches like a taut muscle from the front to the rear. Distinctive 19-inch (front) and 20-inch (rear) light-alloy wheels fill the wheel arches, which stand out prominently from the sidewall. Three different wheel variants all provide a glimpse of the large high-performance composite brakes. Seen from above, a prominent, uninterrupted line runs from the muscle to the rear. This styling feature is also picked up on the bonnet where the eye follows a distinctive contour which flows over the roof between the gullwing doors, right through to the third brake light.

Rear view that emphasizes width

The rear view of the SLS also exudes dynamism and power: the gently sloping boot lid emphasizes a sense of width, an impression reinforced by the prominent vehicle shoulder and the sleek tail lights: fitted with LED technology, the horizontally structured lighting units provide a scintillating view. Wing-shaped LED lighting elements ensure a distinctive, enthralling night design. The Formula-1-style LED fog lamp/reversing light is set down low in the centre. Similarly inspired by motor racing are the black diffuser insert and the two chromed tailpipes of the sports exhaust system. The strikingly tapered rear apron provides an unimpeded view of the wide rear wheels, lending the ‘Gullwing’ its self-assured stance on the road. The spoiler integrated in the boot lid is automatically deployed from a speed of 120 km/h to ensure optimum stability at high speeds.

New colours: “AMG ALU-BEAM silver” and two matt finishes

The color charts for the SLS include nine exclusive paint finishes. The highlight comes in the shape of the unique “AMG ALU-BEAM silver” paintwork: the new, unique process makes the paint shine like liquid metal. The paint covers the body panels like a metallic skin, emphasizes the scintillating design lines of the ‘Gullwing’ more strongly than any previous paint job and makes them even livelier by means of targeted light reflections. This effect is made possible thanks to tiny pigments measuring between 30 and 50 nanometers.

The two matt finishes “designo magno allanite grey” and “AMG magno sylvanite grey” are just as eye-catching: with their matt silk surface they reinforce the sporty character of the two-seater through specific contouring of the crease lines.

Interior with allusions to aircraft construction and motor sports practicality

You only need to open the gullwing doors on the Mercedes-Benz SLS AMG and ease into the sports seats to experience a whole new level of interior. The Mercedes-Benz designers took their inspiration from aircraft construction when styling the interior – immediately bringing an aircraft cockpit to mind. The characteristic styling feature is the dashboard, whose powerful and dramatic wing shape makes for an impression of width. Strikingly integrated into the dashboard are the galvanized air vents with their adjustable, cruciform nozzles and Silver Shadow finish – their shape reminiscent of a jet’s engines. The instrument cluster with its LED upshift indicator and two white backlit dial instruments add another decidedly sporty touch with their metallic Silver Shadow finish. The silver dials have red needles and a 360 km/h speedometer scale. As a central feature of the cockpit, the COMAND APS multimedia system with its 7-inch screen is integrated between the two centre air vents.

The elongated centre console in matt metal similarly picks up on the design theme of the aircraft cockpit. It is home to the AMGDRIVE UNIT, which is inclined towards the SLS driver and allows them to choose their very own vehicle setup. The E-SELECT shift lever, whose styling recalls the thrust control of a jet, controls the AMG SPEEDSHIFT DCT 7-speed sports transmission. All the controls are made out of solid metal, with a high-sheen Silver Shadow surface.

The concave inner panels of the gullwing doors, the high beltline and the powerful side sill panels round off the cockpit-like impression, while imparting a feeling of sports car-like ergonomics. Fine materials such as nappa leather, solid metal and (optional) genuine carbon-fiber facings underline the pronounced “custom-built” nature of the SLS interior, and show enormous attention to detail. Five different designo leather colors are available to meet individual preferences: black, classic red, sand, porcelain and light brown.

Wide-opening gullwing doors for easy entry

Despite the low sitting position of just 369 millimeters in typical sports car fashion, the wide-opening gullwing doors make it easy to get in and out of the vehicle. At the design stage great attention was paid to the widest possible opening angle – it is a full 70 degrees. Equally importantly, the distance between the open doors and the road surface is a generous 1.50 meters, while the entry aperture between the open doors and the upper edge of the door sills measures no less than 1.08 meters. The entrance height, i.e. the distance between the road surface and the upper edge of the door sills is a very low 45 centimeters. As another important criterion for dignified access and egress, two gas-pressure struts positioned next to the door hinges require only very little pressure when opening and closing the doors – even at very low ambient temperatures.

The gullwing doors require less opening space than conventional coupé doors, and can be fully opened in a normal garage. The door is opened from inside by a handle finished in Silver Shadow. The grip section of the armrest molded into the interior door panel ensures problem-free door closing. The operating buttons for the power windows, central locking system and exterior mirror adjustment are also located in the interior door panels for easy access. The feeling of comfortable spaciousness is in large measure due to the generous shoulder-room of 1483 millimeters and elbow room of no less than 1606 millimeters. In conjunction with the generous maximum headroom of 990 millimeters and effective legroom for the driver of 1058 millimeters, the result is a low but extremely relaxed seating position. At the same time the intentionally steep angle of the windscreen ensures good all-round visibility for the passengers.

Sports seats with magnesium backrests

The sports seat backrests are made from magnesium, a high-tech material that combines light weight with high strength. This leads to significant advantages where weight distribution and a low centre of gravity are concerned. The sports seats feature so-called two-zone seat cushions. Prominent side bolsters with a harder foam filling provide optimal lateral support, while the inner areas of the seat cushion and backrest are softer for a high level of comfort on long journeys. In conjunction with the Memory package (optional), the fore-and-aft position, seat height, backrest angle, squab angle and steering column are electrically adjustable; three individual settings can also be stored.

Four-way lumbar supports reliably protect the lower spine, while adjustable side bolsters in the backrests effectively improve lateral support on fast bends. Three-stage seat heating and seat occupancy/child seat recognition in the passenger seat are also standard equipment.

The sports seats with integrated head restraints and sporty transverse fluting are upholstered in designo leather – and two-tone seats are also available in classic red, sand and porcelain. If light brown is chosen as an interior cooler, the sports seats are upholstered in natural leather with particularly high-quality woven leather on the centre seat panels. Depending on the color combination, fluorescent or black piping provides another sporty touch.

The Performance leather steering wheel in a three-spoke design has a 365-millimeter rim with a flattened lower section, shift paddles and a metal insert, underlining the authentic custom-built look and ensuring the best possible vehicle control.

A host of stowage space for hallmark Mercedes day-to-day suitability

The interior of the SLS AMG also impresses with the practical stowage space that makes for the day-to-day suitability typical of a Mercedes. The 3.7-litre glove compartment with a spectacles section is integrated into the dashboard on the
passenger side. To the right of the E-SELECT shift lever there is a small stowage tray with a 12 V socket, or an ashtray with cigar lighter. The armrest behind the centre console not only serves to operate the COMAND Controller: at the touch of a button, the armrest can be moved in two stages to reveal a stowage compartment underneath. This has two cup holders and the telephone cradle (optional), and a holder for the ignition key in the rear section. Other items can be stowed on the rear wall between the seats and in the parcel net in the passenger footwell. Two fixed clothes hooks are attached to the seat backrests, while those in the roof liner fold down and are silicon-insulated.

The button to unlock the boot lid is located underneath the light switch. Alternatively the boot can be opened using the ignition key. The luggage compartment can hold up to 176 liters. A made-to-measure luggage set is available as an option, which enables the boot space to be used to full advantage.

Aluminum spaceframe for lightweight design and outstanding strength

The SLS is also breaking the mould when it comes to the body concept: for the first time, Mercedes-Benz and AMG are presenting a car with an aluminum chassis and body. Compared with the traditional steel design, this results in a significant weight saving, clearly illustrated in the DIN curb weight of 1620 kilograms.

The newly developed bodyshell comprises an aluminum spaceframe. This exclusive design combines intelligent lightweight design with outstanding strength – thus delivering superlative driving dynamics. Lightweight aluminum sections connect the force nodes to a sturdy structure. The large, low-set cross-sections of these aluminum sections ensure high resistance torque, thus providing the required direct transfer of drive, braking and suspension forces. The structure prevents unwanted flexibility; the vehicle responds rigidly, almost without twisting and directly.

45 percent of the intelligent, weight-optimized aluminum spaceframe is made out of aluminum sections, 31 percent out of aluminum sheet, 20 percent out of aluminum cast and 4 percent out of steel. Maximum occupant safety requires the use of ultra-high-strength, heat-formed steel in the A-pillars. The bodyshell weighs 241 kilograms – an absolute benchmark in the super sports car segment when compared with the peak output of 420 kW/571 hp.

Low centre of gravity and transverse reinforcing struts for superb dynamism

The entire vehicle concept has been designed to achieve a centre of gravity that is as low as possible. This applies both to the low connection of the powertrain and axles as well as to the arrangement of the stiffness-relevant bodyshell structure, which has been kept as low as possible. Examples include the rigid flexural and torque connections between the front and rear section and the safety passenger cell, which have been realized consistently using force paths that are as low as possible. This results not only in a low centre of gravity but also a harmonious and, thus, efficient force path in the vehicle structure.

Another prominent feature of the lightweight construction design is the transverse reinforcing struts at the front and rear axle that are integrated into the bodyshell structure. The sections connect the side members precisely where the highest forces act upon the bodyshell under dynamic cornering. The advantages of this sophisticated solution include unrivalled transverse rigidity and the
absence of heavy secondary stiffening or supports.

Passive safety of the very highest calibre

Naturally, the aluminum spaceframe meets all the requirements in terms of passive safety and the hallmark Mercedes-Benz body quality that applies to any car sporting the Mercedes star. The best possible passive safety for the occupants is ensured by the standard-fit three-point seat belts, belt tensioners, belt force limiters and eight airbags: two adaptive airbags and a knee bag each are available for the driver and passenger. Two sidebags integrated into the seats and two separate window bags that deploy from the door waistline are also available.

Fine-tuned AMG 6.3-litre V8 engine developing 420 kW/571 hp

A powerful eight-cylinder engine manufactured by Mercedes-AMG forms the heart of the new SLS. The fine-tuned 6.3-liter V8 engine develops 420 kW/571 hp at 6800 rpm, turning the SLS AMGinto one of the most powerful sports cars in its segment. A power-to-weight ratio of 2.84 kg/hp comes courtesy of the low vehicle weight. The naturally aspirated engine delivers maximum torque of 650 Nm at 4750 rpm. The ‘Gullwing’ accelerates from 0 to 100 km/h in 3.8 seconds, before going on to a top speed electronically limited to 317 km/h (all figures are provisional). Bearing the internal designation M 159, the V8 high-revving engine with its displacement of 6208 cubic centimeters has been thoroughly reengineered compared with the M 156 entry-level engine and boasts all the hallmarks of powerful racing engines.

The principal measures in increasing output include the all-new intake system, the reworked valve train and camshafts, the use of flow-optimized tubular steel headers and the de-throttling of the exhaust system. This results in much better cylinder charging, which feeds through into an increase in output of almost nine percent. The eight-cylinder engine responds swiftly to movements of the accelerator pedal, demonstrating much more pronounced high-revving flexibility across the entire rev range. The switch to dry sump lubrication also translates into a much lower position of the engine in the vehicle. And lowering the vehicle’s centre of gravity has also paved the way for high lateral acceleration and exhilarating driving dynamics.

Perfect synthesis of lightweight design and strength

The use of high-strength components compensates for the increased engine load associated with the higher output. Forged pistons, a reinforced crankshaft bearing, optimized crankcase structure, along with improved lubrication thanks to an on‑demand high-performance oil pump ensure optimum durability. Despite these higher loads, the engine weight for the M 159 has been further reduced. The forged pistons as oscillating masses play a particularly valuable role in this respect, resulting in a curb weight of 205 kilograms and, in turn, a power-to-weight ratio of 0.36 kg/hp – an unrivalled figure compared with the competition. Sophisticated catalytic converter technology enables current and future exhaust emission standards such as EU 5, LEV 2 and ULEV to be met.

A match for demanding fuel consumption targets

Despite its uncompromisingly sporty character, the demanding fuel consumption targets have been met. The SLS AMG consumes 13.2 liters per 100 kilometers (combined, provisional figure), earning it a place at the top of the competitor rankings. Efficiency-enhancing measures include the familiar AMG-exclusive, friction-optimized twin-wire-arc-sprayed coating on the cylinder walls as well as the on-demand, map-optimized oil supply and intelligent generator management: during the engine’s overrun phases and braking, kinetic energy is used to charge the battery, rather than being wasted by simply generating heat. This recuperation assists the driver not only during braking action but also helps convert the braking energy into electrical energy. Conversely, the generator is switched to no-load operation during acceleration, thus reducing the load on the engine.

Dual-clutch transmission with transaxle configuration and torque tube

The AMG 6.3-liter V8 engine delivers its abundant power via an ultra-light carbon-fiber driveshaft at the rear axle – similar to the set-up used on the DTM C-Class racing touring car. The dual-clutch transmission is mounted at the rear (transaxle principle) and is connected to the engine housing via a torque tube. A carbon-fiber shaft rotates at engine speed in the torque tube. The advantages of this sophisticated solution are associated with the rigid link between the engine and trans-mission and, in turn, the optimum support for the forces and torque generated.

A new AMG SPEEDSHIFT DCT 7-speed sports transmission takes care of power transfer. The dual-clutch transmission boasts fast gear changes with no loss of tractive force – in as little as 100 milliseconds. The driver has a choice of four different driving modes: “C” (Controlled Efficiency), “S” (Sport), “S+” (Sport plus) or “M” (Manual) along with a RACESTART function. In the Sport, Sport plus and Manual modes the automatic double-declutching function is active; all the modes can be selected conveniently via the rotary control in the AMG DRIVE UNIT. Optimum traction comes courtesy of the mechanical differential lock, which is integrated in the compact transmission casing.

Sophisticated suspension layout with double-wishbone axles

The chosen solution with a front-mid engine plus transaxle configuration ensures an ideal front/rear weight distribution of 47 to 53 percent. Mounting the engine behind the front axle has created the ideal conditions for consummate driving dynamics with precise steering, first-class agility, low inertia with spontaneous directional changes and outstanding traction. The commitment of Mercedes-Benz and AMG to building an alluring super sports car that combines consummate racetrack performance with hallmark Mercedes long-distance comfort has given rise to an ingenious suspension layout. All four wheels are located on double wishbones with a track rod, a technology that has proven itself in motor racing, right through to Formula 1. With a double-wishbone axle, the wheel location and suspension function remain separate; the spring/damper struts are supported on the lower wishbone. The double-wishbone concept with its high camber and track rigidity positively locates the wheel with minimal elastic movements, providing the driver with an optimum sense of road contact when driving at the limits.

Wishbones, steering knuckles and hub carriers at the front and rear are made entirely from forged aluminum – substantially reducing the un-sprung masses; this configuration also notably improves the suspension response. The long wheelbase of 2680 millimeters not only results in outstanding straight-line stability but also low wheel load shifts, significantly reducing the vehicle’s tendency to dive and squat. The broad track width – front 1682, rear 1653 millimeters – ensures lower shifts in the wheel loads from the inner to the outer wheel when cornering, enabling the tires to retain more grip. The large caster angle of 11.5 degrees significantly increases negative wheel camber when cornering and also improves tire grip – this also ensures outstanding stability when braking heavily while cornering.

Direct steering, differential lock and 3-stage ESP®

The rack-and-pinion steering gear provides a consistently direct steering feel with a constant mechanical ratio of 13.6:1, in tune with the high expectations placed on a super sports car. The power steering provides speed-sensitive assistance and improves the feedback for the driver as the road speed increases: an indispensable factor for high-speed straight-line driving. Mounting the steering gear in front of the engine on the integral subframe enables the engine to be set down very low. The ‘Gullwing’ comes with 3-stage ESP® as standard, providing the driver with access to the three “ESP ON”, “ESP SPORT” and “ESP OFF” modes at the push of a button. The result is even more driving pleasure without compromising active safety at all. In “ESP OFF” mode too, operating the brake pedal restores all the normal ESP® functions.

The system’s traction logic of the acceleration skid control system (ASR) is active in all three ESP®modes. If one of the drive wheels starts to spin, specific brake pressure is applied to improve traction notably – especially in conjunction with the standard-fit mechanical multi-disc limited-slip differential. This means that the engine power is transferred to the road even more effectively when driving in a particularly dynamic style.

Ceramic composite brakes, innovative flow-forming wheels

The AMG high-performance braking system with composite brake discs at the front ensures extremely short stopping distances even under enormous loads. The newly developed, optional ceramic composite brakes with larger brake discs guarantee even better brake performance. The ceramic brake discs will perform reliably at even higher operating temperatures thanks to their greater hardness, all combined with an impressive weight reduction of around 40 percent. Reducing the un-sprung masses has further optimized the handling of the ‘Gullwing’ – which pays dividends particularly when tackling fast bends on motorways.

Lightweight construction was also key when it came to the wheels: weight-optimized AMG light-alloy wheels – 9.5 x 19 inch (front) and 11.0 x 20 inch (rear) – based on the innovative flow-forming principle reduce the un-sprung masses while increasing driving dynamics and suspension comfort. In addition to the standard-fit AMG 7-spoke light-alloy wheels, 5-twin-spoke wheels and 10-spoke forged wheels are available as an option. 265/35 R 19 (front) and 295/30 R 20 (rear) tires developed exclusively for the SLS AMG ensure optimum performance. A tire pressure monitoring system is fitted as standard to permanently monitor tire pressure in all four wheels; individual tires are shown on the display.

The reinterpretation of the legendary ‘Gullwing’ is scheduled to be launched in spring 2010. The sales price is EUR 177,310 (incl. 19% VAT).
