Mercedes-Benz SLS AMG US Version, 2011
The super sports car boasts a purist design, the systematic incorporation of lightweight engineering and superior handling dynamics. At the same time, the SLS delivers the everyday utility and exemplary safety that typifies Mercedes, making the new Gullwing model the ideal synthesis of the strengths of Mercedes-Benz and AMG.
The new super sports car from Mercedes-Benz and AMG dazzles with its unparalleled technology package: an aluminum space-frame bodyshell with gullwing doors; an AMG 6.3-liter, front-mid V8 engine with a top power of 563 hp, 479 lb-ft of torque, and dry sump lubrication; seven-speed dual-clutch in a transaxle configuration; a sports chassis with aluminum double-wishbone suspension; and a DIN curb weight of 3,573 pounds. It's a combination that guarantees supreme handling dynamics. The car's ideal weight distribution between the front and rear axles (47 to 53 percent respectively) and its low center of gravity emphasize the outstanding sports car concept. The Gullwing model accelerates from 0 to 60 mph in 3.8 seconds and has a top speed of 196 mph (electronically limited).
The Design:
The distinctive design of the new Mercedes-Benz SLS AMG dazzles with its passionate sportiness and reinterprets the breathtaking design of the Mercedes-Benz 300 SL, one of the brightest design icons of the Mercedes-Benz brand. With its pure design, the new SLS AMG reflects the teachings of modern sports car design: The nearly 6-foot-long hood, the low greenhouse positioned far back, and the short rear with the extendable rear spoiler symbolize dynamism, as do the long wheelbase, the wide track, and the large wheels. The proportions are determined by the short overhangs and the design of the super sports car, with a low-slung, front-mid engine mounted well back and a dual-clutch transmission in a transaxle configuration. The stylistic highlight is without a doubt the gullwing doors, which impart the SLS AMG with incomparable charisma and make a unique statement in this vehicle segment.
It's not just the gullwing doors that awaken reminiscences of the Mercedes-Benz 300 SL. The characteristic wide radiator grille with the large Mercedes star and the wing-like fin are also reminiscent of the face of the legendary sports car. The three-dimensional, sculptured front with the low, v-shaped front skirt with lateral indentations gives the Gullwing model a powerful stance on the road. The car's dominance is underscored by six large air intakes and the wide-set, vertical headlamps with intriguing components: The central bixenon low-beam headlamps with metallic wing element are framed by two LED blinkers above and two LED daytime running lights below.
Influences from aircraft construction.
The echoes of aircraft construction are stirred by the exposed Mercedes star, whose cone in profile resembles the air intake of a jet engine, and the long hood. The farther the viewer's eye wanders to the front, the greater the curvature of the hood. The same visual effect is produced by the design of the four "Silver Shadow" fins gracing the two air vent grilles on the end of the hood. These lines, which are typical for aircraft, also optically accelerate the air flowing past, giving the Mercedes-Benz SLS AMG an extremely dynamic appearance even when standing still.
Interior with aircraft design elements and racing functionality...
Drivers who raise the gullwing doors of the Mercedes-Benz SLS AMG and sit down in the sports seats will experience a very special interior. In its conception, the Mercedes-Benz designers took their cue from aircraft construction to create an ambience that immediately evokes associations with plane cockpits. The defining stylistic element is the dashboard, whose powerfully extended wing-like profile creates the impression of great width. The dashboard incorporates "silver shadow" electroplated air vents with an adjustable set of nozzles, whose shape vividly calls to mind jet engines. The instrument cluster with its shift-up LED display and two white illuminated circular instruments also appears very sporty in the metallic silver shadow look. The silver dials have red pointers and a 225 mph scale. The main feature between the dashboard's two center air vents is the COMAND multi-media system with its 7-inch screen.
The elongated center console made of real matte metal also plays upon the plane cockpit theme. Among other things, the center console incorporates the AMG DRIVE UNIT, which is aligned towards the driver's seat and enables SLS owners to customize their vehicle set-up. The AMG SPEEDSHIFT DCT 7-speed sports transmission is operated by means of the E-SELECT lever, which is styled like a jet's thrust regulator. All of the control elements are constructed of real metal, boasting a shiny silver shadow surface.
The cockpit impression is rounded off by the concave interior trim of the gullwing doors, the high waistline clearance and the muscular side skirts, all of which also convey the feeling of sports car ergonomics. The high craftsmanship of the SLS interior is demonstrated by the use of refined materials such as nappa leather, real metal, and, as an option, real carbon appliqués. All of these features also express a great attention to detail. To help customize the interior, the leather is available in five designo colors: black, classic red, sand, porcelain and light brown.
The Advanced AMG 6.3-liter V8 engine with an output of 563 hp
The heart of the new SLS is a high-powered eight-cylinder engine manufactured by Mercedes-AMG. The advanced 6.3-liter V-8 engine, which has an output of 563 hp at 6,800 rpm, makes the Gullwing vehicle one of the most powerful sports cars in its segment. In conjunction with the low vehicle weight, this results in a weight-power ratio of 6.3 lb/hp. The naturally aspirated engine provides its maximum torque of 479 lb-ft at 4,750 rpm. The Gullwing vehicle accelerates from 0 to 60 mph in 3.8 seconds and has an electronically limited top speed of 196 mph (all figures are preliminary). The high-torque V8 engine, which is called the M159 within the company, has a displacement of 6,208 cm³. It has been completely restructured compared to the basic M156 engine, and it displays the typical characteristics of high-performance racing engines.
The perfect synthesis of lightweight construction and stability
The Forged pistons, a strengthened crankshaft mounting, an optimized crankcase structure, and improved lubrication by means of a need-regulated high-powered oil pump ensure maximum stability. In spite of the increased demands placed on it, the engine weight of the M159 has been further reduced. The forged pistons, as oscillating masses, make a particularly valuable contribution to this reduction. This results in a dry weight of 452 pounds, and thus a weight-power ratio of 0.8 lbs/hp — a value that is unmatched by any competitors. Sophisticated catalytic converter technology makes it possible to comply with current and future emissions limits such as EU5, LEV2 and ULEV.
Dual-clutch transmission in the transaxle configuration with the Torque Tube
The AMG 6.3-liter V-8 engine transmits its tremendous power to the rear axle via an especially lightweight drive shaft made of carbon — similar to the DTM C-Class touring car. The dual-clutch transmission is located on the rear axle (in line with the transaxle principle) and is tightly connected with the engine housing by means of a Torque Tube. In the Torque Tube, a carbon camshaft rotates with the same speed as the engine. The advantages of this sophisticated solution include the rigid connection between the engine and the transmission, which results in an optimal response to forces and torques.
The new AMG SPEEDSHIFT DCT seven-speed sports transmission is responsible for the power transmission. This dual-clutch transmission is characterized by quick shifting without any interruption of traction — minimum speeds of 100 milliseconds are possible. The driver has a choice of four different driving programs: C (Controlled Efficiency), S (Sport), S+ (Sport plus) and M (Manual), as well as a RACE START function. During the Sport, Sport plus and Manual driving programs, the automatic rev-matching function is active; all of these modes can be comfortably managed via the torque regulator in the AMG DRIVE UNIT. Optimal traction is guaranteed by the mechanical differential lock, which is integrated into the compact transmission housing.

Wide-opening gullwing doors for easy entry
Despite the low seating position typical of sports cars, which means the seats are located only 14.5-inches above the road surface, the wide opening gullwing doors ensure easy entry and exit. The designers made sure that the doors had as large an opening angle as possible, which is why they swing up by 70 degrees. Another consideration that is just as important is that the distance between the opened doors and the road surface is an ample 5 feet, while the size of the passage between the opened doors and the upper edge of the side skirts is a generous 42 inches. By contrast, the entry height (the distance between the road surface and the upper edge of the side skirts) is a low 17.7 inches. Another important criterion for ensuring an elegant entry and exit is that the opening and closing of the doors requires little effort even when it's very cold, because of two gas-dampers next to the door hinges.
The gullwing doors require less room to open than do conventional coupe doors and can be completely opened in standard-sized garages. The gullwing doors can be opened from the interior by means of a silver shadow opening handle. Thanks to the linkage system in the door's armrest, the door is easy to handle when closing. The buttons for the power windows, the central locking system and the exterior mirror adjustment are also easily accessible in the interior trim. The interior has a spacious feeling, due primarily to the large shoulder room of 58.4 inches and the wide elbow width of 63.2 inches. In conjunction with the generous headroom of 38.9 inches and the driver's effective legroom of 41.6 inches, the deep seating position is also relaxing. The passengers benefit from a relatively steep windscreen that provides a good view.
The button for unlocking the rear hatch can be found underneath the light switch. In addition, the hatch can also be opened by using the car keys. The luggage compartment has a volume of 6.2 cu. ft.
The aluminum space frame for light weight and highest strength
The vehicle's all-new body consists of an aluminum space frame, which combines intelligent, lightweight design with the highest strength and thus further boosts the SLS' excellent handling properties. Light aluminum profiles combine the force nodes to create a stable structure. The large, low-lying cross-sections of these aluminum profiles exhibit high resistance torques, thereby ensuring the desired direct transfer of drive, braking and chassis forces. Undesired flexibility is reduced by the structure; the vehicle responds rigidly, directly and as if it was almost free of torsion.
The intelligent aluminum space frame, which has been optimized in terms of weight, is 45 percent aluminum profiles, 31 percent aluminum paneling, 20 percent cast aluminum and four percent steel. Ultra high-tensile, hot-rolled steel is used in the A-pillars to further improve occupant protection. The bodyshell weight is 531 pounds — and given that the maximum power is 563 hp, represents a top value in the super sports car segment.

Direct steering, differential lock and three-stage ESP
With a constant mechanical gear ratio of 13.6 : 1, the rack-and-pinion steering gear delivers a consistently direct steering feel, thereby meeting drivers' high expectations of a super sports car. The parameter power steering works with speed-dependent support and improves feedback for the driver as driving speed increases, a crucial factor when driving straight ahead at high speed. The mounting of the steering gear in front of the engine, on the frametype integral support, allows a particularly low engine position. The Gullwing car features a 3-stage ESP, giving the driver a choice of the three modes "ESP ON", "ESP SPORT" and "ESP OFF" at the push of a button. Even in "ESP OFF" mode, simply applying the brake pedal makes all ESP functions accessible again.
AMG high-performance, ceramic-composite brakes, new "flow forming" wheels
The AMG high-performance compound brakes on the front axle ensure the vehicle quickly comes to a stop even under an enormous load. Even better braking performance is provided by the newly developed, optional ceramic-composite brake system with larger brake discs. Thanks to their increased hardness, the ceramic brake discs offer greater safety at high temperatures and are also impressive by virtue of their weight, which has been reduced by about 40 percent. Through the reduction of the unsprung masses, they further optimize the Gullwing model's handling — which becomes especially apparent during motorway driving around bends at high speed.
