Mercedes-Benz AMG SLS: A legend returns as a super sports car back

With the Mercedes-Benz AMG SLS sees a new super sports car the light of the world. It is the first vehicle developed independently of the performance brand of Mercedes-Benz. The SLS is the myth of the legendary Mercedes-Benz 300 SL from the 1950s to revive, as the legendary Ur-father of the SL-series is. Special features were the characteristic wing doors, the two power domes on the long bonnet and the gill-like air in the front fenders and we may be curious as to how this classic AMG features the SLS at the present time interpreted.

While the optics are not yet much to be seen, the first technical details now known. Already the Technology Package makes the ears sit up with excitement: aluminum spaceframe body with wing doors, a big 6.3 liter V8 with a front mid-engine 571 hp, a 7-speed dual-clutch gearbox in the transaxle arrangement and a sport suspension. The ideal weight distribution of 48 to 52 percent between the front and rear axle and the vehicle deep emphasis emphasize the uncompromising sports car concept further.

The design and development phase for the new super sports car launched in the last quarter of 2006. By the end of 2009, the vehicle testing will be completed. In spring 2010, the reinterpretation of the legendary Flügeltürers finally celebrate their launch.
Consequently, thanks to lightweight aluminum

The radical design of highly talented as driving super sports cars with wide and deep placed behind the front mid-engine provides the same proportions as the lightweight optimized bodyshell concept: presenting the first Mercedes-Benz and AMG is a car with the chassis and body are made of aluminum. This provides over traditional steel construction for a significant weight savings, as a glance at the desired DIN unladen weight of 1,620 kg without driver shows.

The completely newly developed carcass consists of an aluminum spaceframe. This exclusive design combines light weight with high strength, an uncompromising driving dynamics possible. Of course meets the aluminum space frame with all the requirements in terms of passive safety. Despite the low seating position allow the far-sih-opening doors provide convenient entry and exit.

Further developed AMG 6.3-liter V8 engine with 571 hp

The refined 6.3-liter V8 engine from AMG implements a maximum 571 hp at 6,800 rpm. In conjunction with its low vehicle weight is calculated as a power weight of 2.84 kilograms / horsepower. The maximum torque of 650 Nm achieved the eight-cylinder naturally aspirated engine at 4750 rpm. From 0 to 100 km / h accelerates the Hinged doors in just 3.8 seconds and finished his jacking expected only at 315 km / h. The intern called M159 High Speed V8 engine with an engine capacity of 6208 cc was compared with the M156-based engine completely revised.

Complex catalyst technology enables the performance of current and future exhaust emissions limits such as EU 5, LEV 2 and ULEV. Thanks to selective use of efficiency measures, the combined fuel consumption of the Mercedes-Benz AMG SLS is expected at around 13 liters Super Plus per 100 kilometers lie.

The most important measures to improve performance are a new intake manifold, the revision of the valve train and camshaft, the use of flow-optimized Stahlrohrfächerkrümmer dethrottling and the exhaust system dar. This approach has significantly improved cylinder filling reached, which causes an increase in performance.

The eight-cylinder to be agile to respond and pedal movements over the entire rpm range a more joy show strong rotation. With the shift to a dry sump lubrication maker reached a significantly lower position of the engine fitted in the vehicle. The resulting lowering of the vehicle gravity allows high transverse and strong driving dynamics.

Double-clutch gearbox in the transaxle arrangement

His exuberant strength of the V8 engine on a lightweight carbon driveshaft to the rear axle forward - similar to the C-Class DTM Renntourenwagen. The gear has its place in the rear axle (transaxle principle) and is about a so-called "Torque Tube" is fixed to the motor housing. The Torque Tube (Engl. "Torque = Torque," Tube "tube =) rotates a carbon shaft with engine speed. The advantages of this costly solution is the rigid connection between engine and gearbox and the optimum support of the emerging forces and moments.

For the transmission is a new dual-clutch gearbox with seven gears responsibility. The transmission is characterized by fast switching operations without interruption of tractive force. The drivers are four different Fahrprogramme of extremely comfortable to sporty and a Race Start function. Optimum traction while allowing the mechanical, in the compact gearbox integrated differential lock.

The chosen solution plus front mid-engine Transaxle layout provides an ideal weight distribution of 48 percent front to 52 percent rear. Through the installation position of the engine behind the front axle are the best conditions for a perfect driving dynamics with precise Einlenkverhalten, agility class, low inertia in the direction of spontaneous changes and excellent traction given. As standard, the Hinged door on a 3-stage ESP. The driver can also touch the three modes: "ESP On", "ESP Sport" and "ESP Off" is available.

In "ESP On" is specified when starting an unstable driving braking intervention at one or more wheels and a withdrawal of the engine torque. In "ESP Sport" allow the over-or under control interventions as well as the accompanying engine torque intervention higher driving conditions, such as the drift angle. Is "ESP Off" is activated, driving, no interference.

Ceramic composite brakes, and weight-optimized wheel

Shortest stopping distances even with the enormous burden promises high-performance braking system in composite technology. Optionally, there is a ceramic-composite brake system with larger dimensioned brake discs, for less unsprung masses and more braking performance guarantee. The ceramic brake discs are due to their higher hardness on an even higher temperature and also bribe her by about 40 percent lower weight.

Lightweight stand even with the wheels in Focus: Weight-optimized AMG light-alloy wheels in 9.5 x 19 inch front and 11.0 x 20 inch rear reduce unsprung mass and improve driving dynamics and suspension comfort. Exclusively developed for the AMG tires 265/35 R 19 (front) and 295/30 R 20 (rear) while ensuring the best grip.

That's a car! incredible! However, I prefer Audi Nuvolaris... bye friend!
