Japanese tuner Wald International have made a kit for just about every car out there. It’s always simple and it’s always called the Black Bison.

Even so, I reckon the F10 BMW 5 Series’ special package still seems tailored for itself rather than adapted from a different mix altogether.

I claim it to be a special styling package but the Asian company claims it to be a genuine aerodynamic package that has genuine functionality.

There’s a new front bumper, side skirt, rear bumpers with custom design and they’re all extended by an actually functional component.

A new apron, a new diffuser and a small spoiler for the trunk lid, all work together to make the 5 Series Black Bison stick to the road at high speed.

Speaking of which, the high speed we’re talking about is the same as the one the standard versions of the BMW 5 Series since there’s no added performance coming from Wald International.

All the Japanese company adds is a set of re-positioned exhausts which do little but re-arrange the sound and final position of the exhaust tips.

Final tweaks from Wald International come in the form of set of new air vents, custom alloy wheels and some newly appointed LED daytime lights.

There’s a wide variety of available alloy wheels but most of them come in with a very special multi-spoke design.

Interior details are rather limited but Black Bison offers a sport steering wheel and carbon-fiber trim together with some other custom choices.
