BMW testing the next generation 2014 M3 - Turbo V6? Triple turbo I6? Who knows
The new 2014 M3 was spotted testing. What is interesting is that it was spotted in 4 door guise despite past rumors about there not being a 4-door M3 this generation. The main question is what motor this car will get? It is almost certain (seriously, it's certain) it will be a turbo motor of some sort. So will it be a tweaked N55? Will it be an N54 with valvetronic and some tweaks? Will it be a triple turbo? Will it be the rumored V6 with a 6 into 1 exhaust manifold feeding one turbo that then feeds into another larger turbo for some kind of compound setup? At this point, we don't think anyone other than BMW knows.
