Just because the Mercedes CLS 63 AMG is one of the fastest four-doors in the world, doesn't mean owners don't want their rides taken to even more extreme levels of performance and style. This particular model was given to Tag Motorsports for an upgrade, and the Californian aftermarket firm duly obliged by fitting a host of Brabus parts. First up, the German tuner's B63 engine package was added, boosting the 5.5-liter twin-turbo V8's 550 hp to a beastly 620 horses.

Carbon-fiber exterior enhancements were then fitted, including a front spoiler, side skirts and fender vents, rear diffusor and bumper vents. An illuminated trunk emblem, a valved exhaust controlled from the Brabus steering wheel, paddle shifters and pedal set rounded off the rest of the upgrades.
