BMW UK has announced details of the new BMW M3 Coupé.

The new M3 Coupé engine develops 420hp at 8,300rpm and 400Nm of torque at 3,900rpm from its 3,999cc V8-power unit, and red-lines at 8,400rpm. Power is transferred to the road by BMW M’s six-speed manual gearbox and variable M differential.

This engine powers the car from zero to 62mph in 4.8 seconds, on to a limited top speed of 155mph and with a combined fuel consumption figure of 22.8mpg, an eight per cent improvement over the outgoing car.

Like the larger BMW M5 and M6 models, the new M3 Coupé also features an MDrive button. The settings for the optional Electronic Damper Control (Normal, Comfort and Sport), three DSC+ traction control settings and three specific engine control maps, plus the response rate of the Servotronic power steering can be controlled with one button on the steering wheel.

The new BMW M3 Coupé shares many design cues and components with the ‘standard’ 3 Series Coupé model. Only the doors, bootlid, windows and front / rear lamps are carried over. Design cues on the new car are a powerdome and two air intakes in the aluminium bonnet covering the new V8-engine, three large air ducts in the front lower valance to keep the engine breathing, 18-inch double-spoke light-alloy wheels and a side gill in the front wing (including a side direction indicator and the M3 logo.

The new BMW M3 Coupé goes on sale in September and prices will be announced nearer the launch date.
