Mercedes-Benz has announced an AMG version of its new C-Class coupé, promising 0-62mph in 4.5 seconds courtesy of the 6.3-litre V8 AMG engine. This naturally aspirated power unit gives 451bhp and 600Nm of torque, with top speed at an electronically limited 250km/h.

However, there is to be an even more powerful version of the C 63 AMG coupé, boasting 480bhp, and shaving a further tenth of a second off the 0-62mph time: now down to 4.4 seconds. The extra 30bhp is achieved through technology taken from the gullwing Mercedes SLS AMG: the forged pistons, connecting rods and lightweight crankshaft save three kilogrammes, reducing inertia in the high-revving V8 engine.

Visually, the AMG performance package can be identified by the variable intake manifold in titanium grey under the bonnet, the AMG high-performance brakes with composite front discs and red brake calipers, the carbonfibre spoiler lip on the boot lid and the AMG performance steering wheel in nappa leather with Alcantara grip area.

The new AMG two-door coupé enjoys all the technology updates adopted for the C 63 AMG saloon and estate, including AMG Speedshift MCT 7-speed sports transmission with ‘Controlled Efficiency’ mode as standard.

The AMG versions of the new C-Class coupé will go on sale from July 2011.
