Engine hand-built by AMG
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. The special strengths of this high-performance engine include extraordinary responsiveness to movements of the accelerator, a high torque and an unmistakable V8 sound. 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. As a result the roadster achieves performance figures that are even outstanding for the high-end sports car segment: the 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, which is unrivalled by any other series-production roadster.With the exception of two aluminum frames, the body is completely of carbon-fiber materials (CFRP) with steel-reinforced A-pillars and two fixed rollover bars, resulting in low weight, a high-level of energy absorption, plus a torsional rigidity that provides exceptional safety characteristics and further boosts handling. Further safety elements include adaptive airbags, knee and sidebags, belt tensioners and a tyre pressure monitoring system.
The notable design elements of the 722 S include a crystal antimony grey paint finish, black, grid-like air vents on the bonnet and the front, rear light modules with palladium An-Interview-With-Ian-Schrager grey surrounds and distinctive red highlights including painted brake callipers on the 19-inch forged aluminum wheels.
Inside, visual flashpoints are provided by the sports bucket seats upholstered in a combination of semi-aniline leather/Alcantara and complimented by red seat belts plus embossed 722 S lettering on the head restraints. Two-zone automatic climate control, a high-quality BOSE Premium sound system, a multifunction sports steering wheel with shift paddles and a navigation system with an integrated radio and CD player are also standard.
