7-speed dual clutch gearbox for M3

The new BMW M3 will get a seven-speed double-clutch gearbox as an alternative to the standard six-speed manual.

Official confirmation of the long-rumoured transmission came via a document issued to BMW dealers confirming the cars specification.
The new gearbox, called M DCT, will be available from March 2008. Made by BMWs long-standing transmission partner Getrag, it will provide rapid and nearly imperceptible shifts.

The speed of a double-clutch transmission is likely to improve the M3s 4.8sec 0-62mph time by a couple of tenths of a second. The system should offer significantly smoother shifts than BMWs SMG transmission in the M5 and M6.

The transmission will be controlled by a combination of a shift lever, likely to be similar to the M5 and X5s joystick control, and steering wheel paddles.

The 'box has been exclusively developed for BMW, and different versions are destined for the 3-series and the 5-series.
Other options for the M3 (on sale in September) include 19in alloy wheels and electronic damper control. The carbonfibre roof will be standard.

Isnt your 4.8 sec 0-62 time for the e46? I thought the new m3 would be quicker than the 335

Ask the VW owners how much the DSG costs to fix. Since it's a similar concept, repair should be about the same,

I was impressed with the DSG gearbox in the Audi A3 we test drove. Hopefully, the DCT offered by BMW will provide at least the same amount of refinement and performance.

As for that 0-60 time, it's not important. I bet the 0-130mph times in the M3 will undercut the 335i's time by a good margin.
