THE NEW M DOUBLE-CLUTCH TRANSMISSION WITH DRIVELOGIC

BMW M GmbH is proud to be the world's first car maker now offering a
seven-speed Double Clutch Gearbox specially conceived and designed for a high-speed power unit. Compared with all conventional systems available so far, this new gearbox ensures an optimum gearshift and even more dynamic acceleration, and at the same time reduces fuel consumption by a significant margin.

--------------------------------------------------------------------------------

The world's first Double Clutch Gearbox conceived and developed for a high-speed power unit; gearshift without interruption of power and traction; gearshift management with M-specific configuration; seven gears for optimum gear increments ensuring particularly dynamic acceleration; simultaneous debut in the BMW M3 Coupé, BMW M3 Saloon,
and BMW M3 Convertible.

Drivelogic with eleven electronically controlled driving programs in M-specific set-up; five shift programs in the automatic mode, six shift programs in the manual mode including Launch Control for maximum acceleration from a standstill; efficiency-enhancing transmission control in the automatic mode; sequential gear selection in the manual mode.

Fourth, consistently enhanced generation of the automated manual gearbox in M-specific configuration; further enhancement of the car's dynamic driving characteristics and the motorsport-oriented driving experience; manual gear selection by sports selector lever or via paddles on the steering wheel; both control elements in M-specific configuration and set-up; Shift Lights.

Perfect interaction of the M double-clutch transmission with Drivelogic
and the V8 power unit in the new BMW M3; measurable and tangible improvement of acceleration; optional sporting downshift performance with in-between gas.

Elaborate cooling of transmission fluid as the prerequisite for absolute reliability and endurance of the Double Clutch Gearbox with Drivelogic even on the race track, when subject to extreme loads and high outside temperatures.

Optimised comfort in driving manoeuvres at very low speed ensured by Low Speed Assistant; automatic activation of parking lock after switching off the engine.

Further reduction of fuel consumption and emissions compared with manual gearshift and a conventional converter-type automatic transmission.

The proof will be in the driving. A significant improvement in smoothness in automatic mode will be required or BMW is going to be savaged in the automotive press.

Is this just VW's DSG system with an extra gear?

If this functions as well as the VAG DSG trans, then it will transform the M3- the DSG on my 3.2 TT (after I had upgraded it to a high rpm launch and full manual override) made the car into a visceral machine that was a blast on a road course. Made me feel like a F1 driver with the quick and crisp shifts and rev matched downshifts!

Will this gearbox or one in a similar form be made available more widely across BMW's product line (e.g. 335, 550, etc.) ?

I think BMW needs to clarify what makes their 7 speed DSG unique for high power. The Bugatti Veyron has 1001 HP and a 7 speed DSG, which, to me, would make VW the first to have such a transmission.

I'll get a M3 for a week in July.

I definitly want to try this gearbox in the convertible version :D

My guess is that something got lost in the translation and they mean high revs - since 1001 hp is high power to me.

BMW created something truly special with this gearbox. I drove it last week and can tell you that it puts SMG to shame.

SMG is horrible, no offense to those of you who have it this is just my opinion. But it is fact that the sequential manual gearbox has slower shift times than the automatic and a slower 0-60 than the standard (granted the driver knows how to drive), and automatic transmissions.
I also believe it interupts the driving experience too with its pauses in-between shifts and down shifts.
