The BMW M4 Concept Coupe, which will be unveiled at the Pebble Beach Concours d’Elegance this weekend, offers a clear indication of how the forthcoming BMW M4 will look.

Finished in Aurum Dust paintwork, a shade developed especially for the M4, the concept features large air inlets, a front splitter and rear diffuser constructed from carbon-fibre reinforced plastic, a subtle bonnet powerdome and additional vertical air intakes to cool the carbon ceramic brakes.

From the side, the M4 carries the usual BMW proportions of a long bonnet, long wheelbase, and a rear-biased glasshouse. The 20-inch two-tone light alloy wheels feature a characteristic double-spoke design.

A rear lip spoiler aids downforce, while the M gills on the vehicle’s sides function as part of the Air Breather system to ventilate the wheel arches. Carbon-fibre tailpipes peak out from the rear apron.

Although not officially confirmed, the BMW M4 is expected to be powered by a new 3.0-litre twin-turbocharged engine developing around 450bhp.  Estimates for the M4’s performance indicate a 0-62mph time of around 4.5 seconds, with an electronically-limited top speed of 155mph.

The production version of the new BMW M4 is expected to arrive mid way through 2014.
