A rarity on the road, the BMW Manhart Racing MH3 V8 R Biturbo Cabriolet, was spotted in Nurburg, Germany. Introduced in 2012, as the Manhart MH3 V8 R Biturbo, the E93 M3 Convertible has its 4.0 liter naturally aspirated V8 engine removed and replaced with an even more powerful unit: the 4.4 liter twin-turbo V8 S63, the very same unit from the X5 M and X6 M models.

Although the S63 unit provides more than adequate power for the M3, the S63 4.4 liter twin-turbo with its 555 horsepower clearly provides an impressive power boost, even without the tuning package offered by Manhart which brings the total output to 664 horsepower. Maximum torque was also raised to 975 Newton meters.

The enormous thrust is handled by the six-speed automatic from the BMW X6 M, while the differential lock on the rear axle helps the power distribution between the two drive wheels.

The top speed is rated at over 320 km/h. To handle all that power, Manhart fitted the M3 Cabrio with a 4-piston brake system with 396 millimeter discs at the front, at the rear axles 374 mm disk brakes.

The brakes sit behind 20-inch forged aluminum wheels type MHR Concave One Ultra and 255/305 mm wide tires. To grant that optimum contact with the road, the tuner uses a specially tuned KW Clubsport suspension of option 3.
