+1 The hp wars are over for the the average cars. Lexus, infiniti, audi, cadillac, and mercedes did not come out with new engines for their 3-series fighters.
BMW has plenty of time to come up with a new engine. Although, what new technologies are out there? Direct injection, VVT, turbos, superchargers, hemi's are all old now. No longer is it "no replacement for displacement".
Everyone is focusing on fuel efficient engines with moderate power. The performance cars are getting some attention still at least. I'll just say I expected no new engine for the 4 series.
