BMW 335i to get 7-speed twin clutch M DCT
The E92 BMW 335i Coupe will have its 6-speed Steptronic automatic transmission option replaced with the 7-speed BMW M DCT transmission from Getrag, according to an Australian brochure for the E92 last revised on the 30th of June 2008.
Interestingly the M DCT-equipped 335i Coupe will be more fuel economical and less polluting than the 6-speed manual model, with only 9.1 liters per 100km consumed and 217g/km CO2 emissions compared to the manual’s 9.5 liters and 228g/km figures. This is probably due to more efficient transmission of power and more gear ratios to keep the car in the perfect rev range. The M DCT transmission carries a premium of AU$2,447 over the manual model.
This makes the 335i even more appealing as an M3 alternative with a more usable style of power delivery – loads of fat torque across the rev range rather than high revving. However expect the version of the M DCT in the 335i to be sufficiently de-M-ed, it will probably be missing various features like DriveLogic options and etc.

5 years from now, hopefully can see no more gears. The moment the engine hits 2k rpm, will change gear.

Nice….. only if it is affordable.

looks like CVT, manuals, and torque converters are starting to be phased out. dual clutch is the future of car transmission. what next? quad clutch???

With CVTs, the “gear ratios” changes in variation with the car’s engine revs. It is optimising the power transfer from the engine to the drives shafts. But the limitation of the CVT is, how to make it withstand higher torque that is more than 300nm torque, and yet stillbe able to maintain a saloon car’s CVT box size?
I don’ t think the CVT will be phasing out, but more likely to be improved to handle higher torque.

well, the CVT also has that ever-hateful “rubber-band” effect. some manufacturers have fitted their CVTs with some clever torque converter trickery to overcome this but that just seems to me like bastardizing something that was not meant to be.

love that gear box…
