Mercedes-Benz has finally released details and images of the 2011 Mercedes-Benz CL63 AMG and 2011 Mercedes-Benz CL65 AMG.
The CL 63 AMG is powerd by the new AMG 5.5 liter biturbo V8 engine producing a peak output of 536hp and maximum torque of 800Nm (590lb-ft). In conjunction with the AMG Performance Package these figures increase to 563hp and 900Nm (664lb-ft). The engine is outfitted with systems such as direct gasoline injection, twin turbochargers, air/water intercooling and the Controlled Efficiency stop/start function.
The CL 63 AMG accelerates from zero to 100km/h (62mph) in 4.4 seconds, and has a top speed of 250km/h (155mph) (electronically limited).
