The two-seater, with its striking swing-wing doors and styling elements borrowed from the Formula 1 Silver Arrows, builds on the legacy of the famous SLR race cars of the 1950s. Equipped with cutting-edge race car technology and ground-breaking new Mercedes developments, designed to ensure a high standard of safety and suitability for day-to-day use, the new SLR creates a distinctive image for itself as a 21st-century Gran Turismo - a thrilling synthesis of tradition and innovation. History
The Mercedes McLaren SLR is inspired by the Mercedes-Benz 300 SLR of 1955. This sports car racer was actually based on the W196 F1 car, yet named after the road-going Mercedes 300SL Gullwing .
The 21st-century Gran Turismo is made almost entirely from carbon fibre composite. This lightweight yet extremely rigid material originated in the aeronautical and space industries and has also proven its benefits in today's Formula 1 race cars. The weight advantage of the high-tech material over steel is around 50 percent, and the carbon fibres, on impact, are characterised by four to five times higher energy absorption than steel or aluminium. Mercedes-Benz exploits these qualities by incorporating two 620-millimetre longitudinal members made from carbon fibre in the front structure of the new SLR. These absorb the entire energy of the crash in a defined head-on collision, leaving the passenger cell largely undamaged. It is also made entirely from carbon fibre composite and therefore offers a very safe survival zone in side-on or rear-end collisions too.
The SLR has a supercharged 5.5 (5439cc) litre dry sumped 90 degree V8 . It produces 466.8 kW at 6500rpm (626 hp) and 780 N·m (575 ft·lbf) torque at 3250 - 5000 rpm. Unlike most of its contemporaries, is front-mid mounted. AMG technicians took the original SL-55 AMG engine and optimized its capacities by enlarging the fuel pump, the cylinders, and put a larger cooling system that absorbs air to cool down the engine.
Mercedes-Benz has introduced new material technology to the manufacture of the brake discs too. They are made from fibre-reinforced ceramic and are characterised by high fade-resistance and a very long life. In collaboration with the electrohydraulic braking system, Sensotronic Brake Control (SMC™), they allow outstanding deceleration figures too, impressively underlining the motor racing heritage of the Mercedes-Benz SLR McLaren.
