Straight out of the box the Mercedes Benz SL63 AMG is already one of the sportiest models in the luxury carmaker’s lineup, but the car’s heady 525hp (392kW) output was never going to satisfy the guys at German tuner Kicherer. Applying lessons learned from its previous K60 Evo, the tuner has upgraded the 6.2L V8 engine to the tune of 560hp (425kW) and 495lb-ft (670Nm) of torque, lifting performance of the SL63 into supercar territory.

The added performance sees Kicherer's latest SL60 Evo do the 0-100km/h sprint in just 4.3 seconds (0.3 seconds faster than the standard SL63), with 200km/h passing in 14.2 seconds and momentum finally succumbing at an electronically controlled top speed of 320km/h.

A fully integrated aerodynamic package gives off a menacing appearance, while being completely functional, and can be adapted to all current SL models. All additions are available in high-quality carbon-fiber, including the unique front apron that reduces lift on the front axle and allows for improved cooling of the engine. The wheels are ultra-light 20in RS-1 aluminum alloys.

Up back sits a new rear diffuser housing sports exhaust tailpipes, shaded rear lights and a unique boot lid. Inside, Kicherer added an F1-style steering wheel with carbon gearshift paddles, additional instruments and extra carbon trim.

Pricing for the package starts at €21,765 (approximately $32,175 ) plus a Mercedes SL.
