Bingo. THis gear box will be used across the range.

I think the link to that Getrag transmission has been posted at least two times in different threads. And so has that blurry picture of M3 Sedan specs... Nothing new really.

but ocnfirmation nonetheless
if anything we can be sure that this box will be used with the uprated 3.0 turbo, and both M V8 and V10
since the torque rating allows

I'd be surprised if we were to see one, ubiquitous gearbox across the entire range. The gear ratios and final drive ratios differ significantly between the M3 and the M5. (Duh - that's obvious one's a six-speed manual and the other's a 7 gear!)

BMW E92 M3
1st gear 2nd gear 3rd gear 4th gear 5th gear 6th gear
4.055:1, 2.369:1, 1.582:1, 1.192:1, 1.000:1, 0.872:1

BMW E60 M5
1st gear 2nd gear 3rd gear 4th gear 5th gear 6th gear 7th gear
3.990:1, 2.650:1, 1.810:1, 1.390:1, 1.160:1, 1.00:01, 0.830:1

I believe that the gearboxes for the M3 and bigger M cars will differ as the weight and torque capacities will be tailored to the cars' outputs.

Interestingly, see the current set of ratios for the 335i manual:

BMW E90 335i
1st gear 2nd gear 3rd gear 4th gear 5th gear 6th gear
4.055:1, 2.369:1, 1.582:1, 1.192:1, 1.000:1, 0.872:1

Identical to that of the M3.

So in all likelihood, the M3 and 335i will get the same DCT transmission and the M5 and M6 will get a similar but higher rated DCT transmission with different ratios I suspect. Time will tell of course...

On a final note, the increased number of gears allows for closer stacking of the gear ratios, the torque multiplying effect will essentially result in a much more vigourously accelerating M3 equipped with DCT than its manually shifted sibling. I'd be pretty peeved as an enthusiast and an owner of a manual gearbox M3 if the DCT model would be significantly faster all because of an extra gear.

Oh well, that's the price of progress I guess.

Interesting. I'd say the extra capacity is indeed for future V10 applications, i.e. next generation M5/6.

Ok sorry then if you got upset. My bad!

yes Im 100% sure the new gearbox is getting 7 gears.

If the link above is the exact gearbox for the M3 I cant say for 100% (only 90% ).

over-engineered? doest matter. Means more BMW's can use this gearbox in the future.


PS a M5 with SMG is faster than a manual M5. so yes I believe the M3 DCT is going to be faster than a manual M3.

The 6 speed transmission available in US spec M5 has pretty much the same ratios as the 6 speed in M3: 4.06/2.40/1.58/1.19/1.00/0.87. And I believe the 550 also uses the same transmission - it has the same ratios. So I don't think it is beyond the realm of possibility that the M5 and M3 will share a DCT.

I wouldn´t bet on it because M5 allready has 520 Nm of torque so jump to 600 wouldn´t make an big step forward IMO..I mean,"if" updated M will get TT charging,torque should be atleast 650-700 Nm and that´s beynd limits of this gearbox to handle .
