RENNtech tunes the Mercedes-Benz C63 AMG

Outrageous power in an unlikely package is not a thing of the past, and it's unlikely ever to truly die, no matter what the mainstream media may say. RENNtech has embraced that philosophy with its latest creation, a tuned version of Mercedes' C63 AMG - itself an already over-the-top take on a mid-size luxury sedan.

Rated at 548hp (408kW) and 510lb-ft (785Nm) of torque, the 6.2L V8 in the RENNtech C63 AMG tops the factory-tuned model by about 20%, or 97hp (70kW). The power gains come from an all-new exhaust system, including stainless-steel long-tube headers, track-oriented pipes and mufflers plus a reworked ECU. To contain all the extra power RENNtech also upgrades the suspension and fits a new brake package.

Fully adjustable dampers with adjustable camber settings mean the vehicle really can be tuned for the track, or multiple tracks, giving this car a sporting potential many overpowered tuner-cars lack. The upgraded brake package fits right in line with the track-day aspirations of the rest of the car, offering tremendous brake torque and fade resistance with 15.2" two-piece rotors and custom RENNtech calipers. Stainless-steel braided lines ensure solid pedal feel while a pair of carbon-fiber brake ducts help improve ventilation to keep braking consistent lap after lap.
