As expected, the new SLR model impresses again through sportsmanship. With its sporty, premium-quality interior appointments and distinctive motorsport pedigree, the new SLR McLaren Roadster 722 S is limited to 150 vehicles and will inspire the most discerning automotive enthusiasts.
The powerful heart of the SLR Roadster 722 S is a supercharged 5.5-litre V8 engine which is hand-built in the Mercedes-AMG engine shop in Affalterbach. Moreover, with an output of 478 kW/650 hp and 820 Nm of torque, power is on tap almost to excess (SLR McLaren Roadster: 460 kW/626 hp, 780 Nm). Accordingly the new model variant meets the wishes of the most discerning customers for even more sportiness combined with excellent day-to-day practicality.
The five-speed automatic transmission developed by Mercedes-Benz is designed for high performance. It is specially configured for a very high torque, and allows the driver to choose between two sets of shift characteristics. The spring and shock absorber configurations of the suspension are stiffer, and the body has been lowered by 10 millimetres at the front and rear.
The soft top opens and closes semi-automatically in around ten seconds, combining comfort expectations with the purist nature of the roadster. For opening, the roof needs to be unlatched at the windscreen frame and lifted slightly, after which it folds down electrically. The front section of the soft top features an integral aluminium cap, which effectively prevents “ballooning” at high speeds.
SLR Roadster 722 S absolves a sprint from zero to 100 km/h in a breathtaking 3.7 seconds, and 200 km/h is reached in 10.6 seconds. The maximum speed is 335 km/h.
This limited edition of 150 examples is predominantly hand-built at the Formula 1 workshops of McLaren in Woking, England, and is available from January 1, 2009. The price is unknown yet.
