Brabus recently revealed their all new 850 Roadster Edition of the 2013 Mercedes-Benz SL63 AMG. The German aftermarket tuning company upgraded the Mercedes Roadster with a new aero kit, hood scoop, rear diffuser and trunk-mounted spoiler. In addition, the car features a new twin-turbocharged V8 engine that boasts 850 HP and 1069 lb-ft of torque, an increase of over 300 HP. Although the company has yet to release performance stats, we expect this to be in the running for the title of world’s fastest roadster.
