First spy video of the new 2014 BMW M3 Sedan surfaces on the interwerbs. The new M3 Sedan will come to market along with the Coupe model, which according to our sources will carry the M4 moniker.
Another reliable source told BMWBLOG that the engine in the new M3 will be a 3.5 liter V6 BiTurbo engine.
We learned in the past that BMW M was testing different engines for the upcoming M3, one of them the long-time rumored inline-6 tri-turbo. While the inline-6 is a “smoother” powerplant, it is larger in size since it needs to be leaned over for height reasons, hence why we believe the new V6 is the final choice for the M3 and M4.F30post ]
