Here is the full scoop on the new seven speed dual clutch transmission to debut in the BMW M3. Instead of M DCT as previously speculated, the transmission will be called the BMW M DKG instead, presumably meaning the same in German.
A BMW M3 with a 6-speed manual goes from 0 to 100kmh in 4.8 seconds, but with the new M DKG dual clutch transmission, shift time is shaved off by 0.2 seconds to 4.6 seconds. As with most twin clutch transmissions, you have the odd gears on one shaft and the even gears on the other, and upshifts are instantaneous because the next gear is pre-selected. The M DKG is a wet clutch system.
Drivelogic allows 11 different shift patterns – 5 automatic and 6 manual. There is also a separate Low Speed Assistant mode which allows the M DKG transmission to be smoother during slow maneuvering at speeds of less than 5km/h – parking your car for instance. It increases the smoothless and degree of accelerator control achievable by the driver. On the Volkswagen DSG, the throttle is actually way too snappy for you to park your car comfortably. This is because of the nature of the gearbox, essentially robotically controlled clutches,
Of course, manual shifting is available either by pushing and pulling the gear knob, or via paddle shifts on the steering.

I think DKG means Doppelkupplung Getriebe?
The initials are there, a direct translation will give those results as well
Richtig!
I am a bit puzzled by shift time do you mean the time between full engaged gears or do you mean acceleration differences between a manual and a equal DKG equipped machine?
What if it was compared with a 5 speed manual? Less cogs means less time in-between gears. Mucho less Euros too, no?
Oh and since the debut is on a cabrio with a folded hard top, that would mean extra metal and extra weight? Now if there was a better acceleration time than an M3 with the same hp, it would really be amazing. But I seriously doubt it.
the good thing is you will almost always hit this 0-100 time with the DKG vs a manual (which would depend on driver skill).
but call me old school – i still prefer a cog to play around with. :)
it’s sad to think that in years to come, the manual gearbox would become obsolete. sigh.
new technology…after this maybe triple clutch system…??
bmw tech is superb..like it very much…one day will own one beemer for my self…hopefully they also invent tech that can reduce pollution create by vehicle.
sweet thing……
the most amazing thing about bmw is, they continue to make engines that are more powerful, yet either have similar or better fuel consumption than the engine it replaces. plus, the engines are also greener with lower emissions.
Damn… why Doesn’t BMW produce any Manual Transmission for Malaysia anymore? I hate clutchless shifting…
easier to drive, but hardly to get
the cute lil M shifter again .
lolz !!!
