The eight-cylinder biturbo engine also features a generator management system: whenever the engine is on the overrun or when braking, kinetic energy is used to charge the battery rather than being wasted as heat in the usual way. In all other operating modes a combination of onboard network and generator management enables the generator to be kept at a low voltage.
Engine production - tradition of hand-built excellence
Like all other AMG engines, the new eight-cylinder biturbo is assembled by hand in the AMG engine shop taken into commission in 2002. Highly-qualified technicians assemble the M157 according to the "one man, one engine" philosophy, maintaining the very strictest quality standards. This painstaking care is attested to by the signature on the characteristic AMG engine plate.
New AMG triple-spoke light-alloy wheels
In visual terms, the new CL 63 AMG has an even more athletic, confident appearance. The bonnet, headlamps, radiator grille, bicolour tail lamps and the newly designed AMG bodystyling all add more dynamism. The "V8 Biturbo" lettering on the mudguards points to the new powertrain. Also featuring a new look are the AMG triple-spoke light-alloy wheels, painted in titanium grey and with a high-sheen finish, and fitted with 255/40 and 275/40 R 19 tyres. New in the interior are the AMG sports steering wheel with silver-coloured aluminium shift paddles and specially shaped grip area covered with perforated nappa leather, as well as the "AMG V8 Biturbo" start screen in the AMG instrument cluster. As a new optional extra, SPLITVIEW is also available for the COMAND multimedia system.
Direct-Steer system, Torque Vectoring Brake and crosswind stabilisation
With immediate effect, standard equipment on the CL 63 AMG now includes the Direct-Steer system, Torque Vectoring Brake and crosswind stabilisation. With its variable ratio depending on steering angle, the Direct-Steer system helps to ensure a more direct response when cornering, and therefore more responsive handling - in brief: enhanced driving pleasure at the wheel of the Mercedes-AMG CL-Class. Thanks to brief direct application of the brakes on the vehicle's inner rear wheel when cornering, the Torque Vectoring Brake, meanwhile, helps to ensure that the V8 coupé corners precisely and under control at all times. The Torque Vectoring Brake is an additional feature of the Electronic Stability
Program ESP® and not only noticeably improves responsiveness but also active handling safety in critical conditions.
The AMG sports suspension based on Active Body Control (ABC) now also provides crosswind stabilisation as an additional function: thanks to this feature, influences caused by crosswinds are compensated for, or - in the case of strong gusts - reduced to a minimum. ABC compensates against the effect of crosswinds by adjusting the wheel load distribution within milliseconds, using the yaw-rate and lateral acceleration sensors of the ESP®.
Based on the ADAPTIVE BRAKE system with large compound brake discs all round, the AMG high-performance braking system continues to set the benchmark for stopping power, sensitivity and fade resistance.
A unique combination of driver-assistance systems
The unique combination of innovative camera and radar-based driver-assistance systems has been enhanced even further with immediate effect with a view to perfecting the vehicle's active and passive safety. New optional extras now available for the CL 63 AMG include Active Lane Keeping Assist and Active Blind-Spot Assist. Active Lane Keeping Assist comes into play when the CL 63 AMG unintentionally strays over a solid line on the right or left of a lane or on the outside of a bend. In such cases the Electronic Stability Program ESP® applies the brakes to the wheels on the opposite side of the vehicle to prevent it from unintentionally straying from its lane.
Also new is the Active Blind Spot Assist, which warns the driver by displaying a red warning in the glass of the relevant exterior mirror when it detects that changing lanes would be too dangerous. If the driver ignores the warning signal and a vehicle in an adjacent lane comes too close, the ESP® takes corrective action by applying the brakes to the wheels on the opposite side of the vehicle.
Individualisation thanks to AMG Performance Studio and designo
New optional extras from the AMG Performance Studio as well as designo enable the vehicle's individuality to be enhanced even further.

The Technical End
The AMG 5.5-litre V8 biturbo engine with a peak output of up to 571 hp and a torque of up to 900 Nm, is combined with the unique AMG SPEEDSHIFT MCT 7-speed sports transmission, which contributes towards a considerable increase in driving dynamics, while at the same time guaranteeing an improvement in fuel consumption and a reduction in emissions. With a fuel consumption of 26.9 mpg, the new high-performance coupé is also 38 per ent more economical in terms of its fuel consumption than the previous model with naturally aspirated V8 engine.
