BMW’s F10 M5 gets yet another tuning package. This time it’s delivered by the Germans at Manhart Racing and it’s called the MH5 S-Biturbo.

Not the finest exercise in branding or marketing we’ve ever seen but, thankfully, the product itself is miles more impressive than that. Just like the base car, it’s about refined looks and serious performance.

Going one better than that, a refined look, in Manhart Racing’s vision, means not messing around with the original design too much and simply adding a few differentiating tweaks here and there.

That means you get new alloy wheels, 20 inches worth at the front and 21 inches at the rear. It also means you get a new suspension package which works on more than one way.

Lowering the car makes for better stance while giving the car a lowered gravity center which should improve the handling characteristics. The new coilover kit drops 35 mm at the front and 30 at the back.

A sport exhaust system is fitted so you no longer need to listen to the V8 noise being played through the car’s stereo in a rather fake way.

Speaking of V8s making noises, the twin-turbo 4.4 liter one under the bonnet of the F10 BMW M5 is now upgraded by Manhart Racing to produce 633 horsepower and 575 lb-ft of torque.

Even more impressive, it seems that the MH5 S-Biturbo is going to be just the “starter kit” for Manhart racing.

In the future, they plan to introduce versions of the M5 which produce 670 and 735 horsepower.
