Mercedes has released new information about the facelifted CL63 AMG and CL65 AMG.

Like the standard 2011 CL, the AMG variants feature a revised grille, modified bumpers, and restyled headlights. Other exterior goodies include LED fog lights, 20-inch wheels, and an AMG exhaust system.

Inside, the cabin is outfitted with premium leather upholstery, AMG heated / active ventilated front seats (with drive-dynamic multicontour support), a sport steering wheel, an AMG instrument cluster (with RACETIMER), and ambient lighting. Tech features include GPS navigation, an 11-speaker harman/kardon audio system, a 6-disc DVD/CD changer, and an 8-inch COMAND display.

The CL63 AMG is powered by the new 5.5-liter biturbo V8 with 537 hp (400 kW / 544 PS) and 800 Nm (590 lb-ft) of torque. It is connected to a 7-speed SPEEDSHIFT MCT transmission (with Sport, Comfort and Manual shift modes) which enables the coupe to accelerate from 0-60 mph in 4.4 seconds, before topping out at an electronically limited 155 mph (249 km/h).

On the other hand, the CL65 AMG keeps the 6.0-liter V12 with 621 hp (463 kW / 630 PS) and 738 lb-ft (999 Nm) of torque. Since the 7-speed SPEEDSHIFT MCT can't handle all that power, Mercedes opted for the 5-speed SPEEDSHIFT transmission. It allows the car to accelerate from 0-60 mph in 4.2 seconds (just 0.2 seconds faster than the CL63) and hit an electronically limited top speed of 186 mph (299 km/h).

Both cars also have an AMG-calibrated Active Body Control (ABC) suspension, an AMG-specific power-assisted speed-sensitive rack-and-pinion steering system, and a high performance braking system with cross-drilled discs which measure 15.4" in front and 14.4" in the rear.
