When it comes to Wald International's Black Bison tuning program, the best members of the herd seem to be Mercedes-Benz models. The Japanese tuners seem to be particularly adept at making all kinds of cars from the Silver Arrow more aggressive and aerodynamic. The only knock on Wald is that its Black Bison's don't feature beefier engines. Still, most of the Mercedes featured here can easily do over 150 mph. When you have a car that looks as good as these, sometimes it's a good idea to drive slow.

Seen here is the Black Bison S63. Wald International's tuning package includes CV-1 22-inch wheels and a lowered suspension. The 5.5-liter V8 engine was left completely untouched.

Wald brought the CLS Coupe into the Black Bison fold earlier this year. The tuned coupe features an aggressive body kit consisting of a new front bumper, front wings, side vents, trunk-lid spoiler and gigantic diffusers. Other highlights include blacked-out lights, a lower suspension and custom wheels.

This CLS550 is one part Black Bison and one part DBX. Black Bison provided the body kit and DBX provided the orange vinyl wrap. (Is there such a thing as an orange bison?) The 22-inch Forgiatos are pretty awesome, though.

Wald showed love to the newest CLS-Class by bringing it into the Black Bison family and giving it LED daytime running lights, side skirts, a sport front fender, exhaust tips, a rear bumper with LED brake light, and a trunk and roof spoiler. Nice call on the black matte wheels.

Wagon-lovers are going to be all over the Black Bison E-Class Wagon. Wald took a stock wagon and turned it into a monster (appearance-wise), adding a ton of vents, a DTM sports muffler, LED daytime running lights and a mean front bumper.
