Live from the launch: Mercedes CLS

Mercedes claims to have invented the four-door coupe with the original CLS, a car that sold 170,000 examples thanks by and large to its curvaceous take on an E Class sized saloon.

The UK accounted for around 10 percent of those sales, and next year we'll get the new version which includes a completely fresh design and a four-cylinder diesel engine amongst a plethora of other improvements.
