Mercedes has launched the CLK 63 AMG and tweaked the pre-existing CLK 500, with both receiving new power plants. The AMG gets a 6.2 litre naturally aspirated V8, with 481bhp, while the 500 "only" gets a new 338bhp 5.5 litre V8.

The new AMG variant also gets re-tuned sports suspension, 18 inch rims and a high-performance composite braking system. It also comes with probably the best auto gearbox available anywhere - the awesome AMG version of the 7-G Tronic, which is about as smooth as a supermodel’s inner thigh.

The AMG costs from £65,215, the 500 from £47,490.
