We know M is spending lots of the R&D budget on weight management right now on so I question the notion that they can meet an M3 cost requirements with all this new kit.
Thats totally right ... there is no ... no ... no ... chance that the M-GmbH would develop an new White-Paper V6 for the new F3x M3 ... people must read threads in the right way. The rumor is not about an new V6 for this car ... the rumor is about taking the S63TT from the ongoing M5 with 2 cylinder less ... so you get an potent 3.3ltr.V6TT and then put an third Turbo ontop/ in the V. This engine could also share many parts with the V8 S63!
