With convertible versions almost hitting British shores, BMW has announced coupe models of the all-new 6 Series that will go on sale in October 2011.

Longer, lower and wider than the outgoing car, design highlights of the 6 Series coupe include the long, flat bonnet that elongates the shape and the roof sweeps down in one fluid line.

But, it's clear that the styling of this Jaguar XK and Mercedes E-Class Coupe rival is more of evolution of the outgoing car than an all-new design.

Inside, there's more head and legroom and the new 6 Series Coupe has a more driver-focused dashboard and centre console. The Coupe is a practical choice too, with 460 litres of boot space. Just two petrol versions will be available at launch: the 640i and 650i.

Both are V8 engines, which feature single and twin turbo technology to increase performance and efficiency. The 650i sprints to 62mph in just 4.9 seconds and on to a limited top speed of 155mph, yet it's still capable of 27.2 mpg on the combined cycle with CO2 emissions of 243g/km. The 640i has the same top speed, but gets to 62mph in 5.4 seconds, has a 36.7 mpg fuel figure and CO2 emissions of 179g/km.

Detailed prices and specification will be announced closer to the launch.
