How do you really know that this is the new M3 gearbox? Or is it an educated guess?

With 7 speeds and 600 Nm torque capacity, it's actually more closely suited to the C63 AMG...

I still think that the M3 will be a 6 speed box. Of course, I'm often wrong...

They are talking about it on Rennteam and M3post and and the M3 is getting a manual + DCT (DSG) in march/april 2008. I even know a guy having the M3 on order and he is waiting for the new gearbox , he also got a confirmation from bmw that a seqventiell gearbox is coming before the summer.

Wake up Martin , that M3 is getting DCT is old news are you really sincere that you didnt know this?

also SMG is being replaced with DCT(DSG) in all cars in the future.

I think this is a leaked document

Thanks J_M. This is the gearbox I would want in my new M3.

martinbo

Please man.

Read my post.

I ask how do you know that THIS (i.e. the 7DCI600 TRANSMISSION) is THE new M3 DCT gearbox? Everybody's talking about it... yes, there was information given sometime back as to the M3 getting a DCT gearbox. I know - really I do.

But, is this that you're showing us, the new gearbox?

a) How do we know that the next DCT gearbox for the M3 will be a seven speed? Why can't it be a six speed?

b) This gearbox is over-engineered by a capacity of 200 Nm for the application in the M3. I find this odd.

Hence my comment, that this transmission appears to be more applicable to the 7 speed, 600 Nm C63.

I'm not disputing that the M3 will get a new DCT transmission.

maybe because this same gearbox with a bit of tweaking will be fitted to the V10 in the near future? it isn't over engineering, it is economies of scale
it is cheaper to design and manufacture a gearbox that will function on several models with different margins, then to build and design independent gearboxes
especially since these will be comparatively low volume boxes anyway

It isn't IMO, as you can see there's no 7th gear ( - )

vabboud

no 7th gear but the place for one, so why leave a blan for something inexistent? there will be a 7 gear box later on

Perhaps it is also going to be used in the future torque monster aka the rumored M5 with a turbo charged V10.
