Here’s a sizzling update to the recently revealed 2011 CL-Class. Mercedes-Benz has just given to the press fresh images and lively details of the future CL 63 AMG and CL65 AMG models. Now, if you’re no stranger to AMG and Mercedes-Benz, you’ll know that this pair spells out high performance. Well, not in the super car realms of the SLS AMG, but enough to take the flagship pole in the company’s line of premium passenger vehicles.

There’ve been a lot of rumors that Mercedes-Benz might drop the old ’63′ badging and use numbers that are representative of the new engine displacements to be put under the hood. However, as these images reveal, nothing can be farther than the truth.

Performance wise, expect no less mind-blowing, owing to a highly modified version of the new 5.5-liter twin-turbo V8. Throw into the mix AMG’s seven speed SpeedShift automatic tranny, the new CL 63 will be capable of 400kW of power at 5,500rpm, while pulling a maximum of 800Nm of torque anywhere from 2,000 to 4,500rpm. The sprint from zero to sixty miles per hour will take merely 4.4 seconds, while top speed will be electronically limited to 250kph, just to make sure the driver and passenger stay in one piece.

However, if you want to add even more thrill, you can always opt for AMG’s performance package which easily bumps maximum horsepower to 420kW, cutting zero to sixty time by 0.1 second. Of course, you’ll be able to pull up to 299kph, nearing the boundaries of super car performance.

The CL 65, meanwhile, is completely mind-shattering, with a highly-tuned version of the previous 6.0-liter twin-turbo V12 coupled to a five-speed automatic. Performance figures? 463kW horsepower, 1000Nm maximum torque and 4.2 seconds racing from zero to sixty miles per hour. Need we say more?

There are tons of new features to be made standard which includes the COMAND infotainment system with voice control. Delivery date for the base CL models? End of 2010. AMG models? Early 2011. Stay tuned.
