Rumors of a possible triple-turbo six-cylinder have been the headliner for the next-generation M3 (though we aren't sold on the idea) but reports have also indicated the 2014 BMW M3 would drop the sedan version entirely. These spy shots appear to refute that idea.
The images show what looks to be a very sport version of the next-gen 3-Series (you can find our spy shots of the standard 2013 3-Series here), but without the power bulge found in the hood of the current M3. That bulge is what makes room for the screaming 4.0-liter V-8, and its absence tends to confirm the next M3 will be a six-cylinder.
Power estimates for the next-gen M Division turbo six range around the 450 horsepower mark, with BMW's characteristic inline six-cylinder layout a given. Whether it will feature two turbos (as we expect) or three (as rumored), it is said to be all-new, rather than an updated version of the N54/N55 found in the current 3-Series lineup.
Notable differences from the standard 2013 3-Series previously spied include a more aggressive aerodynamics kit, particularly at the front end, with much larger air intakes, likely to keep the intercooler cool and the brakes happy. Tiny openings in the camouflage hint at LED fog lights, while the familiar BMW ring-shaped headlights can be clearly seen beneath their own strips of obscuring tape.
The hood is shaped slightly differently as well, without the two creases seen in the previous non-M prototypes. The new converging curves, first seen on the 2012 6-Series, can also be seen peeking out from under the camo.
At the sides, we see flared wheel arches that make room for wider wheels, large brake discs within the wheels, and a low side-sill aerodynamic/appearance addition. Moving to the rear, split-quad exhaust outlets are nestled at the bottom of the bumper, but few other details can be discerned, as even the tail lights are mostly masked.
The next-generation M3 should arrive in mid- or late- 2013, several months after the 2013 3-Series' debut in late 2012. We'll bring you the latest spy shots and details as we uncover them.
