To my Infos there are only two
6 cylinder possibilities, because the M-GmbH has developed them for testing:
- an 3.3ltr.V6 TT(T) ... developed from the S63 M5 4.4ltr.V8 TT
- an 3.2ltr.I6 TT(T) ... developed from the N55 engine
In the moment the descision has gone to the inline-6 3.2ltr. because itīs the cheapest alternative
... the 3.2ltr is the maximum displacement they can get from the N55 engineblock ... more displacement wouldnīt come because that meens an complete new engineblock ... and that is too costly.
Kind of sad how it's now "too expensive" to make a block just for the M3, even though BMW sells WAY more units now than they did back with the E30 or real E36 M3's.

Agreed. It's more of an electric supercharger than a turbo since it doesn't run off the exhaust.
