Not as quick as i thought found this on 4car, having said that it is not slow??
The BMW M3 coupe is back, the fourth-generation model going on sale in the UK in September.
Recently seen in near-production concept form at the Geneva Motor Show, it shares much of its sheet metal with the standard 3-series Coupe, but has been sported up with a new domed bonnet with air intakes, a unique front grille and valance for improved air intake, side 'gills' in the front wings, more aerodynamic door mirrors, a rear diffuser, twin exhaust tailpipes, a bootlid lip spoiler and 19" double-spoke alloy wheels.
Power comes from a 420bhp 4.0-litre V8, which redlines at 8,400rpm; peak torque is 295lb-ft at 3,900rpm, although 85% of that torque is still available at 6,500rpm. A six-speed manual gearbox with variable differential is fitted; the differential can apportion up to 100% of the power to the wheel with the most grip
Topline figures are 155mph, 0-60mph in 4.8 seconds and 22.8mpg. The fuel economy - an 8% improvement over that of the outgoing M3 - is enhanced by the M3's lighter weight (a carbon fibre roof panel that also lowers the car's centre of gravity and aluminium suspension components) and brake energy regeneration, whereby the alternator charges the battery with energy otherwise lost under deceleration.
Like the M5 and M6, the M3 Coupe has the MDrive button for variable power outputs and selectable settings for the electronic damper control, traction control, power steering assistance and engine control mapping.
More details - and pricing - will be announced nearer to launch.
