For some people, BMW's E92 M3 coupe is a near-perfect vehicle. It offers great looks, a BMW driving experience, luxury, sportiness and the unmistakable performance that only an M-series can offer. But to some, 420-hp out of the M3′s V8 might not be enough to satisfy their needs. That's where Manhart Racing comes in, transplanting the M3′s much bigger brother's X6M powerplant into the sport coupe chassis. That's right, the thrill of a twin turbo M3 coupe can now be experienced.
By replacing the M3′s V8 with BMW's X6M powerplant, Manhart Racing was able to squeeze plenty of extra horsepower thanks to its twin turbo forced induction. With some ECU modifications and a new exhaust, the M3 puts out 724-hp and 641 ft-lbs of torque.
To back up the power, Manhart Racing also added some carbon fiber components, suspension upgrades, and a lightweight set of BBS wheels.
