2012 Mercedes-Benz SLS AMG Roadster

Every supercar from Mercedes-Benz gets its open-top version. This is  the case for the SLS AMG and the German manufacturer has decided to publish several official pictures taken during its phase test to give us a nice taste.

Always in the test phase in Stuttgart, Mercedes-Benz currently put the final touch on its all new convertible. This is the second car to be developed independently  by AMG and its development period took 3 years during which considerable attention has been given to body rigidity, handling and dynamics driving. The coupe and the roadster have been developed together because as a standard, the car's chassis has been conceived for a convertible. Extensive investigations have helped to achieve specific objectives such as the design of the bodywork, weight distribution, the engine position and the gravity center.

The gull-wing doors are gone and a soft top made of 3 layers of cloth appears. It can be opened and closed in only 11 seconds and up to a speed of 31 mph. The Mercedes-Benz SLS AMG Roadster has undergone serious tests by engineers including 16 different tests in the rain. The durability of the soft top is very important and has been tested over  20,000 cycles of opening and closing when the car was stopped and 2,500 on the road. For now, it has completed 6,000 miles on the Nürburgring.

Thanks to the excellent work realized by the engineers, the roadsters body means it weighs just 5 pounds more than the coupe. We can't see its final appearance as it still contains hidden areas like the headlights and the logo. The engine is the same as the coupe, a 6,2-litre V8 and 563 hp which allow it to shoot from 0 to 62 mph in about 4 seconds and reach limited electronic speeds of 197 mph.

The Mercedes-Benz SLS AMG Roadster will be officially revealed at the next Frankfurt Auto Show this fall and will be available at the end of the year as a 2012 model.
