Based on the Mercedes-Benz SL65 AMG, the Brabus 800 Roadster will be unveiled at the 2013 Geneva Motor Show. Brabus is claiming their 800 Roadster is the fastest roadster in the world. Powered by a 6.0-liter bi-turbo AMG engine that has been uprated to Brabus T65 RS specification and produces 800 horsepower, the 800 Roadster reaches a limited top speed of 217 mph and runs 0 to 62 mph in 3.7 seconds. The roadster is also fitted with a Brabus limited-slip differential with a locking rate of 40 percent and an adjustable ABC suspension that can be lowered an inch by a special Brabus control. On the outside, the new roadster wears some carbon fiber bodywork including a front spoiler, front fenders, side air vents, and rear diffuser. All aerodynamic enhancing parts on the roadster have been tested in a wind tunnel to make sure that they actually function how they should instead of just looking good. The carbon fiber bodywork is available in painted, glass, or matte carbon fiber. The 800 rides on a set of Brabus Monoblock R “Platinum Edition” forged wheels that are wrapped in Pirelli, Continental, or Yokohama tires. The ten double spokes of the wheels are organized in two matte titanium and polished plans. The front wheels are 9Jx20 with 255/30 ZR 20 tires and the rear wheels are 10.5Jx20 with 305/25 ZR 20 tires. Inside are aluminum paddle shifters for the roadster’s seven-speed automatic transmission and a range of upgrades to choose from. Some upgrades include a speedometer with a 220 mph dial, scuff plates with back-lit Brabus logos, and carbon fiber and wood trim in any color a buyer desires with a range of surface finishes.
