Raising the redline.

The eight-cylinder engine.

Power all the way to the redline - the BMW M3 Sedan's eight-cylinder engine has a genuine race-car character. Every component has been carefully optimized to maximize output and engine speed. The result: 414hp, up to 8,300rpm, and 295 lbs of torque at 3,900 rpm. And that's not all: the individual throttle butterflies and engine management system ensures the engine responds rapidly to driver inputs, translating every touch of the right pedal into instant acceleration.
