Looks like 4 cylinder only in the F20/F22, which has been my belief for a while. I don't see why BMW could not produce an N20 variant with close to 300 RWH and significant weight reductions through the use of lightweight body and suspension components. Throw in the lightweight 6 MT from the 1M. If it was light enough, what's not to like about it?
As for FWD cars, Mini has proven that premium FWD is a go.
