I think the Z4 M will get a turbocharged motor. That is heavily rumored to be the route the route they are going for the F1x M5/M6 and F3x M3. I strongly suspect that the Z4 M will get a brand new M-developed turbocharged inline six (possibly based on the N54 as a starting point, possibly not).
The other question is - will there be a Z4 (M or otherwise) coupe? If so what is that - the e88? It can't be "e90" since that is taken.
