Manhart Racing has made a couple of upgrade packages for the BMW M5 F10 so far, and they cannot be stopped. Here’s yet another one, another MH5 S package, but this time with 646 horsepower. It also looks a bit different than the previous efforts – its kind of stealthy – so guess it was worth the hassle.

The new MH5 comes with a tweaked software that removes the top speed limiter, so the car’s 4.4 liter V8 can use all of its 646 horsepower and 773 Nm of torque to take the M5 all the way to 316 km/h.

As for the looks, the car comes with a front spoiler lip, MHR rear diffuser and rear spoiler, modded hood with GTR air intake, full grey-matt metallic wrapping with decorative MHR stripes, and a set of MHR08 Deep Concave by ADV.1 wheels in size 9.5 x 21 inches (front) and 10.5 x 21 inches (rear), with 265/30ZR21 and 305/25ZR21 tires.

This car will be on display at the Essen Motor Show next month.
