German tuner VATH has unveiled a new performance package for the facelifted Mercedes-Benz CL63 AMG coupe. The V63S kit includes a software upgrade for the ECU, which increases the bi-turbocharged V8's output from 563hp and 590lb-ft of torque to an incredible 630hp and mighty powerful 686lb-ft. In addition to the removal of the electronic speed limiter, the end result is an increase in top speed from 155 mph to 187 mph, with an acceleration time from 0-62mph in only 4.3 seconds.

VATH has also upgraded the CL63 AMG's braking system and has fitted a new set of 20-inch lightweight alloy wheels to accompany the advanced braking system. Some other notable features are a new carbon fiber radiator cover, rear diffuser and an available boot lid spoiler. There are also all-new custom leathers and trims available for the interior as well. Pricing for the upgraded package has not been officially announced yet.
