Mercedes has unveiled official pictures and information of the face lifted CL-Class luxury coupe. Set to be released in 2011, the CL as previously reported, will feature a completely revised twin-turbo 4.6-litre V8 BlueDIRECT engine that produces an impressive 435hp and 700Nm of torque. This will be housed in the CL 500 which carries the Blue EFFICIENCY name, highlighting the cars improvements in all round efficiency.

This is seen by the 12 percent power increase the current engine produces over its predecessor despite having 0.8 litres less displacement. This improves fuel efficiency to 9.5 litres per 100 kilometres. Performance has also improved, with the new V8 now propelling the car to the century mark in just 4.9 seconds, which was previously 5.4 seconds.

Other factors that improve fuel consumption in the new V8 include the incorporation of the BlueDIRECT technology along with the consistent use of friction-optimised pistons, piston rings, cylinder barrels, the on-demand control of oil pump, the new three-phase thermal management in the coolant circuit and the ECO start/stop function plus alternator control.

The top of the line CL 600 on the other hand, will have the 12-cylinder biturbo 5.5-litre engine under its hood which produces 517hp and 829 Nm of torque, propelling it it from 0 to 100km/h in just 4.6 seconds.

Helping keep all that power contained will be the usual list of award winning Mercedes safety systems along with new ones such as Active Lane Keeping Assist, Active Blind Spot Assist, Adaptive High Beam Assist, Night View Assist, Active Body Control (ABC) with crosswind stabilisation.

This keeps the CL’s new sleek body out of harms way, which as you can see has also gone through revisions which include a new grille, modified bumpers, restyled headlights (with integrated LED daytime running lights), LED fog lights, new tail lights, and a sportier exhaust system.

Moving on inside, the CL-Class gets a multifunction steering wheel that incorporates nappa leather as standard, along with the choice of various wood trims to give it that special ambience.

The COMAND system (a Mercedes equivalent of the iDrive), now features SPLTVIEW technology, which allows the driver and front passenger to view different things at the same time. It also comes with Bluetooth®, USB and SD card compatibility that plugs into a 7.2 GB hard drive for all your entertainment needs.

A picture gallery is available of the CL500 and CL600 models after the jump.
