Spied! BMW M4 Coupe Caught in San Francisco

The next-generation of BMW’s M cars are getting closer to hitting the road. Spy photographers recently caught near-production-ready versions of the next-gen BMW M3 sedan and its coupe-sibling, the BMW M4, rolling through San Francisco.

Spied in San Francisco traffic, the M3 and M4 appear to be getting increasingly close to production. Both sports cars will be powered by an inline-six with as many as three turbochargers. Power output will likely be north of the outgoing car’s 414 hp. BMW M division managing director Friedrich Nitschke told us the M3 and M4′s new I-6 “will have one of the best engines we have ever done.”

In a recent interview with Motor Trend, Nitschke divulged a bit more information on the M3 sedan and M4 coupe. From the new M cars, we can expect 50:50 weight distribution and a new differential with torque vectoring like the M5. Weight-savings materials should also be found in the next-gen M3 sedan and M4 coupe and convertibles. Both cars will have carbon fiber roofs and trunks with an aluminum hood and aluminum, magnesium, and carbon fiber in its crumple zones.

We’re expecting the next-gen BMW M3 to bow at Frankfurt this year, with the BMW M4 following at January’s Detroit auto show.
