A sinister package for the 2012 Mercedes CLS 63 AMG has been released under the Black Bison line of tuning kits from Wald International. They are notorious for blacking out almost everything with their car projects, and kept the same mindset with this Mercedes. On the outside is an aero kit comprising of a new front bumper with LED daytime running lights, rear bumper, side skirts, new front fenders, and a spoiler on the trunk lid. Matte black alloy wheels round out the exterior styling of the car tuning package, while Wald continued working under the hood of the Mercedes CLS with new performance tweaks.

In the engine bay of the Mercedes CLS 63 AMG you will find the new factory 5.5-liter V8 twin turbo powerplant producing 525PS (386 kW) and 700Nm of torque (516 lb-ft). With the Wald tuning AMG Performance package, power was increased by 33PS (24 kW) and 100 newton meters of torque (84 lb-ft). This impressive figure allow the Wald tuned Mercedes CLS to accelerate from 0 to 100 km/h in just 4.4 seconds while reaching an overall top speed of 299 km/h or 186 mph.
