The new BMW M3 Coupe
The re-birth of an icon
BMW UK has announced details of the new BMW M3 Coupé, a model that 21 years ago created an entirely new segment for super-high-performance compact cars.
Engine and Drivetrain
With DNA connecting the new M3’s engine to that of the BMW Sauber F1 Team, the racing link is maintained in the fourth generation M3. 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. To highlight the flexibility of the engine, 85 per cent of torque is available from 6,500rpm. Power is transferred to the road by BMW M’s six-speed manual gearbox and variable M differential which conveys up to 100 per cent of available power to the wheel with most grip.
Like its predecessor, the new V8-powered BMW M3 easily breaks through the magical 100hp per litre barrier, offering 105hp per litre. This engine powers the car from zero to 62mph in 4.8 seconds and on to a limited top speed of 155mph. However, these supercar levels of performance do not compromise economy with the car still delivering 22.8mpg on the combined cycle, being an eight per cent improvement over the outgoing car.
BMW EfficientDynamics
This relative frugal economy is delivered, in part, thanks to BMW’s EfficientDynamics programme. Far from only influencing the smaller-engined cars in the range, EfficientDynamics offers benefits to one of the most sporting cars offered by BMW, courtesy of Brake Energy Regeneration. This technology uses an Intelligent Alternator Control and Absorbent Glass Mat battery to recognise when the engine is on over-run and activates the alternator to charge the battery with what would previously have been wasted energy.
The drivetrain in the new M3 Coupé features lightweight, but high-strength, materials. Using an engine block manufactured alongside F1 engines at BMW’s light-alloy foundry at Landshut, Germany, the new V8 powerplant weighs a mere 202kgs, 15kgs less than the six-cylinder engine it replaces.
Coupé design but with BMW M flair
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. However, a number of subtle performance enhancements combine to deliver an unmistakably sporting outline. A striking powerdome and two air intakes in the aluminium bonnet cover the new V8-engine and help engine cooling.
In profile, the new M3 Coupé features 18-inch double-spoke light-alloy wheels as standard, with a striking 19-inch wheel available as an option. Another BMW M trait, a side gill in the front wing, also includes the side direction indicator and the M3 logo.
From the rear, an aerodynamically-efficient diffuser emphasises BMW M’s trademark twin double exhaust pipes protruding from beneath the valance. The bootlid also features a discreet lip spoiler.
The new BMW M3 Coupé goes on sale in September 2007 and prices will be announced nearer the launch date.
