Here is a set of spy shots of the upcoming Mercedes-Benz 2012 Mercedes C63 AMG Black Series spied for the first time testing on the Nürburgring circuit.
This test prototype is based on the facelifted C-Class which debuted earlier this year and is sporting a Black Series body kit including the wider wheel wells as the car is rolling on larger rims. It's also packing some extra horses under the hood from the standard C63 AMG.
Expected to power this C-Class Black Series is AMG's 6.3-liter (6208cc) V8 engine dialed up to an output of around 517 PS (380 kW / 510 bhp). Gearbox will be the seven-speed MCT transmission while other modifications likely include a revised suspension set-up, a limited-slip rear differential and carbon ceramic brakes.
