Manhart Racing in Wuppertal, Germany are now transplanting their technique into a BMW M3 Convertible. The transplant involves a similar setup as the MH3 V8 RS Clubsport, but with a lower performance. However, it still creates the quickest and most powerful convertible of its class.

As in the MH3 V8 RS Clubsport, you will find the 4.4 liter V8 twin-turbo engine from the X6 M under the bonnet of the E93 series-based MH3 V8 R Biturbo. The Germans also fitted with a large carbon fiber cover. Thanks to special Manhart Racing (MHR) developed software, the 4.4 litre V8 twin-turbo produces 655bhp and a maximum torque of 975Nm. The electronic Vmax was removed providing a top speed more than 320km/h.

Manhart has installed its own in-house designed stainless steel downpipes, as well as an Akrapovic Evolution Titanium exhaust system with a 200 cpsi sports catalytic converter system and four 90mm tail pipes.

The MH3 V8 R Biturbo has been equipped with a MHR braking system with four-piston calliper brake pads and 396mm brake discs taken from the X6 M, with the discs being drilled, on the front axle and 374mm brake discs on the rear axle. The vehicle also features the six-speed sports automatic transmission from the X6 M, and is fitted with a differential lock for optimal traction.

The MH3 V8 R Biturbo has been fitted with several MHR carbon fiber elements, an engine bonnet with GTR air intakes, mirror caps and diffuser. In addition, BMW performance carbon flaps have been installed and MHR decorative strips have been applied.

The MH3 V8 R Biturbo rolls on MHR Concave One Ultra-light forged wheels. The 9×20 inch and 12×20 inch wheels are shod in tires sizing 255/30ZR20 up front and 305/25ZR20 at the back. The vehicle is also equipped with an MHR suspension system (by KW V3) with in-house adjustment.

Inside the cabin, the tachometer on the vehicle reaches 400km/h. The tuner has also installed its own in-house display system, which provides the driver with all kinds of information on operating parameters and driving performance data.
