| Mercedes-Benz has announced full details on the 2012 CLS 63 AMG model. New for the CLS 63 is now AMG's 5.5 liter biturbo V8 engine, which replaces the outgoing naturally aspirated 6.3 liter V8. The new 5.5 liter biturbo unit features a peak output of 410 kW (557 PS/550 bhp) and 800 Nm (590 lb-ft) of torque with the AMG Performance package.
