F30 M3: what the future holds (speculation)

[330CIZHP]

No way in hell. 7000 rpm is the maximum all new M cars are getting. Watch the spy videos of the F10 M5 and it has the same engine X5 M has down to the redline.

I had to keep telling the 1-M fanbois who kept claiming it will have 8000 rpm redline (even when the gauge cluster in press drives was visible) and somehow claimed BMW was sandbagging.

It is simple common sense. BMW is moving to turbo cars for lower emissions, cheaper production costs, cookie-cutter technology that could be applied to several models and also for better fuel economy. Having a high-revving engine defeats all of these purposes.

Having a high revving engine works against all of these philosophies plus R&D for a turbocharged + high-revving engine is enormously more expensive than just N/A high-revving model because of the stratospheric centrifugal force and stress engine has to sustain at very high revs.

maybe even a turbo charged V6...just look at the power a GTR is putting out....

an I-6 3.0 is too limiting....so I say a V6 maybe possible...

He said I6 3.0 . Can't make it much larger without making the engine longer, which would mean a larger, heavier front. And don't think stroke can get any longer either. It's pretty much maxed out. You can find 14L I6s on big rigs, so he obviously didn't mean I6 was limiting.

thanks, exactly what I meant...
