Hot new C63 AMG Coupe

Mercedes-Benz has revealed the hottest version of its new C-Class Coupe, a 451bhp C63 AMG.

The C63 AMG will go on sale this summer and prices will start at around 58,000. It is also available with a performance pack that boosts output to 480bhp.

The 'lesser'-powered version accelerates from 0-62mph in 4.5 seconds, while the slightly lighter and more powerful car knocks 0.1 seconds off that time. Both cars have a limited top speed of 155mpg, emissions of 280g/km and will do an average of 23.5mpg.

A seven-speed automatic gearbox is also common to both, while the performance pack car gets new engine parts and a lightweight crankshaft.

The performance pack also brings a carbonfibre rear spoiler and composite front discs with red calipers, so it's likely to be significantly more expensive than the standard version.

At the other end of the range, C-Class Coupe buyers can get on the ownership ladder from around 27,500.
