The M3 features a high-revving powerplant like the M3s of previous years, but this time the motor is a V8. It also features tuned suspension, a six-speed manual transmission, a carbon fiber roof, and all the exterior modifications typical of an "M" car.

The M3's V8 powerplant has two more cylinders than its predecessor, delivering 420 horsepower from 4.0 litters and maximum torque of 295 pound-feet at 3,900 rpm. In keeping with BMW's high-revving "M" tradition, maximum engine speed is 8,300 rpm. The engine is the lightest V8 in the world, weighing less than the previous M3's inline-six.

Reminiscent of the carbon fiber roof panel used on the M6 coupe, the M3's CFRP roof cuts unnecessary weight, and lowers the car's center of gravity. It also lets the roof edge appear flatter and thus lowers the perceived body height.

The production M3 is pictured with 18-inch wheels, though BMW is also expected to offer 19-inch alloys similar to the Y-spoke ones featured on the M3 concept.
