BMW M3 with dual-clutch

Volkswagen won't be the only company on the market with a dual-clutch gearbox for much longer, following a report by Autocar citing dealer sources that BMW will offer a seven-speed unit similar to the People's Car's DSG in its new M3.

Developed exclusively for BMW, the Getrag-built gearbox will be called M DCT. Controls will be via either a shift lever or steering wheel mounted paddles. The dual-clutch design is in some ways an evolution of the sequential manual gearbox currently found in BMW's M5 and M6 and the new transmission should provide smoother and quicker shifts. A couple ticks should also be shaved off the car's straight line acceleration time.

The M3 goes on sale in September, but those wishing to get one with the M DCT will have to wait until March.

2008 BMW M3 V8

BMW has revealed the production version of the 2008/2009 M3 coupe. The unveiling comes only weeks after the automaker revealed the M3 Concept at the Geneva Motor Show in Switzerland. Like the concept, the production car features a high-revving V8 powerplant, tuned suspension, a six-speed manual transmission, a carbon fiber roof, and all the exterior modifications typical of an "M" car.

Due to go on sale in North American in mid-2008 as a 2009 model, the M3 will target the Lexus IS-F, Audi RS5, and Mercedes CLK63 AMG. Convertible and sedan variants are expected to follow later in 2008.

The M3's V8 powerplant has two more cylinders than its predecessor, delivering 420 hp from 4.0 litters and maximum torque of 295 lb-ft at 3,900 rpm. In keeping with BMW's high-revving "M" tradition, maximum engine speed is 8,300 rpm. The engine is the lightest V8 in the world, weighing less than the previous M3's inline-six.

Reminiscent of the carbon fiber roof panel used on the M6 coupe, the M3's CFRP roof cuts unnecessary weight, and lowers the car's center of gravity. It also lets the roof edge appear flatter and thus lowers the perceived body height.

The production M3 is pictured with 18-inch wheels, though BMW is also expected to offer 19-inch alloys similar to the Y-spoke ones featured on the M3 concept.
