Here are the first pictures of the 2013 Mercedes S63 AMG, during testing near the Nürburgring.
The heavily camouflaged prototype is distinguished by a high performance braking system and AMG wheels. Currently, additional information is limited, but the car will likely be equipped by a twin-turbo 5.5-liter V8 engine, capacity of 518 hp and 699 Nm of torque, along with a 7-speed Speedshift MCT automatic transmission.
