2009 Mercedes-Benz McLaren 722S Roadster

Mercedes-Benz has revealed details of its astonishingly quick McLaren 722S Roadster, the car named in tribute to the Mercedes-Benz Roadster that Sir Stirling Moss drove to victory in the final Mille Miglia road race in Italy back in the 1950s.

Delivering 478kW, acceleration from 0-to-100 km/h in 3.7 seconds and a maximum speed of 335km/h, this two-seater cabriolet, according to Mercedes-Benz, surpasses the existing benchmark among open-top super sports cars – the SLR McLaren Roadster. In addition to increased power, the new SLR McLaren Roadster 722 S features even more dynamic suspension tuning and improved aerodynamics.

At the heart of the SLR Roadster 722 S is a powerful 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. The maximum speed is 335km/h, which Mercedes-Benz claims is unrivalled by any other series-production roadster.

With just 150 examples, the Mercedes-Benz McLaren 722S Roadster will be predominantly hand-built at the Formula 1 workshops of McLaren in Woking, England, and the car will be available from January 1, 2009.

2008 Mansory Mercedes-Benz McLaren SLR Renovatio

(from Mansory Press Release) World premiere at the 78th Auto Salon Geneva 2008
MANSORY Renovatio – The ultimate makeover for the Mercedes Benz SLR McLaren

Since 2004 McLaren has been producing the Mercedes Benz SLR McLaren in Woking in almost unaltered form. MANSORY, the specialist in upgrading super sports cars and luxury limousines has now presented the gull wing racer at the Auto Salon 2008 in Geneva in a new design. Not only did the bodywork get a facelift, the engine was also given modified supercharging by means of MANSORY compressor technology. Ultra-light forged wheels and a superlative automotive interior complete the all-round renewal.

Fresh design in tried and tested quality
During the development of the MANSORY Renovatio great value was attached both to individual design as well as aerodynamic efficiency. To save weight MANSORY fashioned its body components out of carbon. The production car body is also made out of this extremely light and resilient material. One component of the body kit is the front apron in dynamic sport design. It channels the airstream perfectly to the custom-designed intercoolers of the performance kit and so ensures an extra helping of cooling air. The new side skirts constitute the optical link between the front and rear wheel arch extensions. These calm the airstream between the axles and create space for the outlets of the MANSORY side pipe exhaust system. The new rear apron with integrated diffuser takes care of additional downforce and puts the final touch to the sporting lines of the styling package.

New components for impressive performance boost
The 5.5 litre V8 engine with its standard 626 hp likewise profited from the comprehensive changes. The motto of the MANSORY engineers when redesigning the engine was “evolution instead of revolution.” The leading idea was not about making major changes to the SLR’s core. Rather, existing components were swapped for modified developments by MANSORY itself. For example, use is made of new high performance compressors and tailor-made intercoolers. The finishing touches to the performance upgrade are a sports air filter and modified engine management. As a result the Renovatio is two tenths faster from zero to 100 km/h than the super sports car production model. The top speed increases to 340 kph. Following the alterations the Renovatio has 700 PS and generates 880 Nm torque on the crankshaft.
