Manhart revealed its tuning package for the BMW M3 Cabrio. It is dubbed as the Manhart MH3 V8 R Biturbo and is equipped with an X5 /X6 M engine. Days ago, Manhart presented its modified BMW M5. The most significant change on the M3 Cabrio is the V8 4.4-liter twin-turbo engine of the X6 M with a carbon fiber cover.

Manhart optimized the software and modified the power unit to deliver 655 hp (488 KW) and 719 lb-ft (955 Nm) of torque.

By taking out the electronic top speed limiter, the modified M3 Cabrio can hit a top speed of over 199 mph (320 km/h). In addition, they also built an Akrapovic Evolution Titanium exhaust system with a sports catalytic converter and four 90mm tailpipes.

To manage this much power, the M3 is given X6 M-sourced 396mm drilled brake discs at the front and 374mm discs at the back with four-piston calipers.

It also gets the six-speed automatic transmission that originated from the X6 M and that was given a differential lock to offer improved traction. It rides on front 9x20 wheels with high-performance 255/35ZR20 tires and rear 12x20 alloys with 305/25ZR20 rubbers. The M3 Cabrio also got a MHR suspension system by KW with in-house changes.
