Manhart Racing also had a go with the lovely BMW 1M Coupe, and managed to give it a pretty substantial boost in power.

They’ve fiddled with car’s electronic brain, and also fitted it with an even sportier exhausts system. The result is an extra 80 hp from the six-cylinder turbo, for a total output of 420 hp. With that, the 0 to 100 km/h sprint drops to 4.5 seconds.

At this stage Manhart offers a set of very cool 20 inch wheels with 295 tires as well, but the final version will also have a carbon front spoiler, in addition to the new rear diffuser you see in the picture below and a redesigned interior with bucket seats. The car also gets some stripes and “25 Jahre” graphics on the sides.
