The upcoming 2013 BMW M3 Sedan was spied near Nurburgring race track. The test prototype showcases the typical M3 with a wide track, M front bumper, square LED headlights, large brakes and the signature four exhaust pipes at the rear.
Due out in 2013, the M3 Sedan will be followed by the M4 Coupe, the new naming convention that BMW contemplates using for the high-end sporty model of the 4 Series family.
BMW will continue to offer the new M3 in three body variants: sedan, coupe and convertible.
The design of the 2013 BMW M3 Sedan builds atop the newly unveiled F30 3 Series and will incorporate the typical M design cues. The biggest change within the M3 family will come this time from the engine offering. Same sources stated that for the past year BMW has been testing different powerplants in M3 prototypes, from inline-six turbo engines, to a newly designed and unique V6, and even the current V8 naturally aspirated engine.
We also recently learned that the V6 tested is a 3.3 liter BiTurbo engine with around 450 horsepower.
The new 2013 BMW M3 will make its debut at the Geneva Auto Show in March 2012.
