Manhart Racing has unveiled their new MH5 S-Biturbo based on the new BMW M5. The first iteration of their tuning package takes the twin-turbo 4.4 liter V8 from 555 horsepower to a whooping 624 ponies, and the torque numbers from 780 Nm (575 lb-ft) to 880 Nm (649 lb-ft).

The German tuner has already announced that consecutive power upgrades will follow, staring with 661 horsepower and ending around 725 hp.
Details are limited, but Manhart said these models will have modifications to their turbochargers, downpipes and exhaust system.

Manhart will also offer adjustable coilover suspension that reduces the ride height 35mm front / 30mm rear. The MH5 now sits on custom wheels in 20-inches for the front and 21-inches at the rear. For increased sound acoustic, a sports exhaust system is included in the catalog as well.
