Manhart Racing has a long and glorious career in fitting BMW cars with massive engines. Their latest creation is a BMW M3 powered by the 4.4 V8 biturbo from BMW X6M.

Now, it wouldn’t be that outlandish if they hadn’t fiddle with it as well! But they have, and boosted the power from 555 hp to a simply staggering 750 hp and 910 Nm of torque. The V8 has been fitted with a larger air intake system, reinforced pistons and rods, new cooling system, new exhausts and catalysts.

Given the 1,590 kg kerb weight of the car, this M3 has a power to weight ratio of 2.12 kg/hp. That is very high. In plain English that means 0 to 100km/h in 3.2 seconds and top speed of 350km/h.

To cope with that ferocious speed, the tuner has fitted the car with MOVIT performance brakes with 396×34 millimeter discs with 6 piston calipers at front and 380×32 millimeter discs with 4-piston calipers at the back. It also gets 20-inch wheels with Continental Sport Contact 5 high-performance tires.

What they’ve done to the exterior is a bit too childish, but as the name says it’s a Clubsport and will be used mostly as a track toy. So that huge wing, carbon body panels, and fender flares are alright. The car also gets a racing interior with a roll cage, carbon seats and a new steering wheel.
