The new CL 65 AMG continues the successful twelve-cylinder tradition of Mercedes-AMG with an up-to-date V12 power unit which exhibits stunning performance characteristics. Thanks to twin turbocharging this engine develops 612 hp and makes a remarkable 1000 Newton metres of torque available from 2000 rpm. This makes the CL 65 AMG the most powerful AMG model to date.

The new AMG engine is based on the 12-cylinder unit of the Mercedes-Benz S-Class. In addition to an increase in displacement from 5513 to 5980 cubic centimetres, numerous other modifications are responsible for the output and torque increase in the new CL 65 AMG. For example the AMG engineers have increased the cylinder bore from 82 to 82.6 millimetres, lengthened the stroke of the crankshaft by six millimetres to 93 millimetres and increased the charge pressure of the turbochargers to a maximum of 1.5 bar. In addition they have used forged pistons, main and big-end bearings made from extremely high temperature and pressure-resistant materials and enlarged the apertures in the injection nozzles to achieve a higher fuel flow. Power is transferred by a five-speed automatic transmission with the SPEEDSHIFT function and steering-wheel gearshift. The exceptional torque of the V12 is always safely under control, thanks to modifications to various transmission components, the rear axle differential, the drive shafts and the wheel carriers.
