Ladies… erm, scratch that. Boys, this is where the tuning business gets serious. Aside from being in Germany, it’s actually at Manhart Racing.

As their name suggests, these fellas don’t really get too bothered about fitting ostrich skin on the upholstery or tinted windows.

In keeping with the stereotype we all have build up around the Germans, Manhart Racing stuck to the important serious bits of the tuning process.

Their take on the four wheel drive version of the V8 powered BMW 6 Series Gran Coupe gets engine upgrades, chassis tweaks and braking improvements first of all.

Some minor tweaks to the bumpers, the skirts and the exhaust tips tell us just how serious they are. They didn’t even change anything about the looks that wasn’t very low down on the car anyway.

Under the bonnet, its 4.4 liter twin-turbocharged V8 engine goes from 450 horsepower and 479 pound-feet of torque to a much beefier 543 / 538.

The change is achieved by punching up the boost levels and so the exhaust system itself needed a lot more work in order to keep everything top notch.

Now that acceleration and speed has been tweaked, it only felt natural for the tuner to give the braking system a serious upgrade.

This is why the used the F10 BMW M5 brake package, albeit with a few modifications and then fitted the M Division’s 20 inch wheels around them.

Finally, the chassis receives a bit of sharpening up with an adaptation package from MHR. All that acceleration and braking will bring about some more stress to the entire thing so it had to be dealt with somehow.
