A seven-speed sequential manual gearbox

Filed under: Uncategorized — admin @ 4:50 pm

A seven-speed sequential manual gearbox and a superior chassis and suspension compliment its engine.

The all-new M6 features weight-saving technologies such as a carbon-fiber roof and 19-inch forged aluminum wheels that are almost four pounds lighter than regular cast wheels. With almost 500 horsepower available, BMW claims the M6 will hit 60 mph in under 4.6 seconds, and it will run to 20 5mph without the traditional 155-mph speed limiter.

The suspension, though similar to that of the M5, is specially tuned to take advantage of the M6′s shorter wheelbase and lower center of gravity. Massive cross-drilled brakes enable the M6 to pull up from 60 mph in less than 118 feet. The new M6 also uses BMW’s new third-generation seven speed Sequential Manual Gearbox (SMG) with Drivelogic. Drivelogic offers the choice of 11 different change patterns, depending on the speed of change required.

The new SMG gearbox also offers safety benefits when downshifting on slippery surfaces. If it detects the rear wheels locking up, the clutch opens for a fraction of a second to ensure traction is maintained.
