BMW M4 to be revealed in 2014

January will see the unveiling of the hotly anticipated BMW M4 Coupe at the Detroit Motor Show.

The new model is designed to be more eco friendly, faster and lighter than its predecessors, and even though the official eco statistics are yet to be released, the company says that both M cars will emit under 200g/km of CO2 - or about 33 mpg on the authorised EU test.

BMW have put the same amount of effort into making this model lighter as they have into adapting the spec. The M4 comes with a carbon fibre roof, aluminium bonnet and a tailgate made from plastic panels on a frame of carbon fibre. As a result, the car will weigh under 1,500kg, which is 80kg less than the E92 M3 coupe.

There is a choice between a twin-clutch DCT with paddleshift transmission and a six-speed manual, and BMW are offering buyers the option of having carbon-ceramic brakes for the first time.

Performance figures are not yet in the public domain, but it is widely expected the car will go from 0 to 60 in a commendable 4.5 seconds. No price will be confirmed until we get closer to next year's summer launch date in the UK, but it should enter the market at circa £57,000.

It could turn out the BMW M4 will become one of the success stories of 2014.
