Earlier today, German Special Customs revealed a new tuning kit for the Mercedes CLS63 AMG. Their program updates the looks of the high-performance four-door coupe and increases its performance considerably.

Powered by the standard 5.5-liter V8 biturbo engine, the GSC Mercedes CLS63 AMG develops 750 hp and 1,150 Nm of torque. This is 232 hp and 452 Nm of torque more than the stock vehicle. Now this is a power upgrade! To get the extra horsepowers, the engineers swapped the CLS63′s air intercooler with a water cooler, and gave it bigger turbos and a bespoke exhaust system. The awesome power of the GSC Mercedes CLS63 AMG translates into a 0-62 mph (0-100 km/h) acceleration time of just 3.7 seconds and a top speed of 350 km/h. The GSC Mercedes CLS63 AMG comes equipped with a set of 20-inch alloys, an adjustable KW coilover suspension and Continental tires.

GSC’s body kit for the Mercedes CLS63 AMG includes a more aggressive front bumper with integrated LED DRLs, a new hood, mud guards, and side skirts. The rear of GSC’s Mercedes CLS63 AMG shows a newly designed bumper with an integrated carbon fiber diffuser and a four-tailpipe exhaust.
