Interesting to see mercedes move to go 4 cylinder hybrid with the next gen C63 AMG. I think BMW inevitably will have to follow... Also very interested in Mercedes newly introduced electric turbo, that reduces lag. I would love to see BMW introduce a newly developed mild hybrid 4 cylinder engine for next gen M2, as long as It looks and sounds anything like the DTM, P48 engine with a plus 7K RPM redline. A carbon fiber roof and the new optional carbon bucket seats should bring overall weight down significantly. But hey, who am I...
