The new CL 65 AMG and S 65 AMG from Mercedes-AMG GmbH are the most powerful models the brand has produced since it was established 35 years ago. The exclusive Gran Turismo and the dynamic luxury saloon are powered by a newly designed 6-litre V12 engine whose biturbo technology gives it a level of performance previously unheard of in this engine size class: the twelve-cylinder AMG power plant has an output of 450 kW/612 hp and develops its maximum torque of 1000 newton metres between 2000 and 4000 rpm. These impressive figures are responsible for a new dimension of performance: both vehicles can accelerate from 0 to 100 km/h in 4.4 seconds and on to an electronically limited top speed of 250 km/h. Much of the credit for this impressive performance is shared by the all-new design of the biturbo system, which features larger turbochargers and a new, more powerful charge-air cooling system, and the increase in the engine displacement (to 5980 cc) as well as many other engine design measures.
Power is transmitted by the AMG Speedshift five-speed automatic transmission with steering-wheel gearshift controls. The engine's high maximum torque level of 1200 newton metres has been limited electronically to 1000 newton metres and an number of measures – including the adoption of newly clutch pack discs with a high-quality metal coating as well as modified shift and torque-converter-lockup logic – have been taken to optimise key transmission components. The modified drive shafts and upgraded hub carriers also reflect the high levels of power and torque available.
Inside, a particularly stylish ambience is created by the extensive use of fine wood trim elements and the 'Exclusive nappa' leather upholstery, which is available in three colours. Electrically adjustable AMG sports seats with the exclusive AMG upholstery piping layout and perforation pattern, optimised lateral support, multi-contour and memory functions as well as seat heating make every journey in the CL 65 AMG a delight, whether it involves twisting country roads or long-distance motorway cruising. The S 65 AMG has dynamic multicontour front seats which are electrically adjustable and feature a memory function and seat heating as well as the characteristic AMG upholstery piping and perforation pattern. The distinctive style of the twelve-cylinder flagship models is rounded off by the AMG instrument cluster calibrated up to 360 km/h, the AMG ergonomic steering wheel with gearshift buttons, and the chromed stainless-steel door sills featuring the AMG logo.
