Our spies managed to catch several new images of the all-new Mercedes SL 63 AMG. Spied at the Nürburgring, the heavily camouflaged prototype features a long bonnet, AMG wheels, cross-drilled brakes, and a folding metal roof. Inside, the interior will sport a redesigned steering wheel, an SLS-inspired centre console and an improved COMAND system. Like the 2011 S 63 AMG, power will be provided by a 5.5l V8 producing 406kW and 800 Nm of torque. For those who want more power the SL 63 AMG will be availble in an AMG performance package which will tweak the engine into producing 426kW and 900 Nm.
