2012 Mercedes Benz CLS 63 AMG "Masterpiece of performance art".

An all-new, handcrafted 5.5-liter biturbo V-8 delivers 518 hp and 0-60 mph in just 4.4 seconds† along with improved emissions and efficiency. An optional AMG Performance Package raises the ante to 550 hp and 0-60 in 4.3 seconds. A new 7-speed AMG SPEEDSHIFT MCT transmission features a wet startup clutch, a fuel-saving new ECO Start/Stop system and shifts as quick as 100 milliseconds. From the console, the AMG DRIVE UNIT offers driver-selectable setups for the transmission, suspension, steering and 3-mode ESP®. Massive multi-piston brakes and 19″ wheels set off exclusive bodywork, all wrapped around a cockpit inspired equally by its racing roots and the Mercedes-Benz standard of refinement.
