The 2009 Mercedes-Benz SLR McLaren Roadster 722 S is a limited edition (150 will be produced) model which delivers 650 hp (478 kW), acceleration from 0 to 62 mph in 3.7 seconds, and a maximum speed of 208 mph (335 km/h). Both the 722 S Roadster and the standard Mercedes-Benz Mclaren SLR Roadster feature a fully retractable carbon fiber folding soft top capable of withstanding high speeds. This endows both models with a very high degree of safety and extreme torsional stiffness. In addition to increased power, the new SLR McLaren Roadster 722 S features even more dynamic suspension tuning and improved aerodynamics.

By naming this new model variant the SLR Roadster 722 S, Mercedes-Benz is recalling the historic victory won at the classic Mille Miglia long-distance race in 1955 by British motor-racing legend Stirling Moss and his co-driver Dennis Jenkinson, in a Mercedes-Benz 300 SLR with the starting number 722.

Powering 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. With an output of 650 hp and 820 Nm of torque the 722 S Roadster can meet the demands of the most discerning drivers, with a high level of performance 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 722 S Roadster are stiffer, and the body has been lowered by 10 millimetres at the front and rear. This helps increases the handling stability of the Mercedes-Benz SLR McLaren Roadster 722 S. The lightweight, 19-inch forged aluminium wheels allow a view of the red-painted brake callipers on the heat-resistant carbon-fibre/ceramic brake discs.

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.

The handling and aerodynamics of the SLR 722 S Roadster were optimised for high speeds in the wind tunnel. The aerodynamic concept follows that of the SLR Coupé, with an airbrake integrated into the boot lid, an enclosed underbody and a diffusor in the rear bumper to ensure the greatest possible downforce on the rear axle. The so-called airsplitter at the front end augments this downforce, while small wheel spoilers reduce turbulence at the rear axle.

A high level of safety is provided by unique carbon-fibre crash structures, steel-reinforced A-pillars and two fixed rollover bars. Other safety features include adaptive airbags, knee and sidebags, belt tensioners and a tyre pressure monitoring system.

Inside, the Mercedes Mclaren SLR 722 Roadster features sports bucket seats upholstered in a combination of semi-aniline leather/Alcantara. Striking visual highlights are provided by the contrasting seams in 300 SL red, the embossed 722 S lettering on the head restraints and the likewise red seat belts. Frequently used controls such as the shift and parking brake levers are lined in particularly high-grip and moisture-absorbing suede leather. Generous use of carbon-fibre underlines the high-performance philosophy and adds a particularly puristic touch.

The Mercedes Mclaren SLR 722 S Roadster features 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.
