2011 Mercedes CL63 AMG and CL65 AMG – official details

Many who shop in this segment opt for something more flashy, which is why the recently facelifted Mercedes CL-Class is a relatively rare sight. But this big, comfy coupe has a heart of a beast in AMG form. The CL63 AMG will feature a smaller but more powerful than before twin-turbocharged 5.5-litre V8 producing 536 hp and 799 Nm of torque; the addition of the AMG performance package sees this figure increase to 563 hp and 899 Nm.

This is good enough to haul the big car from 0 to 96 km/h (60 mph) in just 4.4 seconds, on to an electronically limited top speed of 250 km/h. The AMG performance pack is faster by 0.1 sec and does a restricted top speed of 300 km/h. Using a smaller displacing engine as compared to the naturally aspirated 6,208cc V8, fuel efficiency has improved by a substantial 27%. Even performance cars are subject to downsizing now!

Want 12 cylinders? You’ve got to have the CL65 AMG then. The 6.0-litre V12 gets a 17 hp hike which gives you 621 hp and an equally seat bracing 999 Nm of torque. 0 to 96 figures are down to 4.2 seconds while restricted top speed is also at 300 km/h.

The gearbox used in the CL63 AMG will be the 7-speed SPEEDSHIFT MCT transmission with the option of Sports, Comfort and manual shift modes. Due to the higher power from the CL65’s V12, Mercedes has opted for a 5-speed SPEEDSHIFT transmission for the range topper.

These new engines are housed in a facelifted body similar to the non AMG CL-Class, but with an AMG body kit that includes a new front grille, revised bumpers, headlights, AMG exhaust system and 20-inch alloy wheels. Inside, updates include a new steering wheel, and different trim options. Direct-Steer, Torque Vectoring Brakes and Crosswind Stabilization systems are standard here.
