Mercedes-AMG SL63 Falls Victim To Extreme Tuning

German aftermarket tuner Keyvany, which recently applied its Mansory-like upgrades to a Lamborghini Urus, has revealed its take on the Mercedes-AMG SL63, modifying the car with extensive visual upgrades and enough performance to give supercars a run for their money.

The build's name is unclear, as the tuner uses both "K820HP" and "SL820HP" when referring to the finished product. Either way, the 4.0-liter twin-turbocharged V8 no longer produces 577 horsepower and 590 lb-ft of torque.

The tuner did not stipulate how the output was increased but says the engine now produces 820 hp and 723 lb-ft of torque, nearly as much as the incoming SL E Performance will offer. No acceleration or top-speed claims have been made, but it won't be slow. The new SL now comes standard with Merc's 4Matic+ all-wheel-drive system so that this new model won't turn its rear tires into smoke like old-school modified SLs.

Keyvany says this build is a "First Edition" and claims the monstrous creation sports the world's first carbon fiber body kit for the R232 Mercedes SL. Again, no weight-saving figures have been revealed, but it's nice to think this may be lighter than the standard SL, considering that the model's name stands for Sport-Leicht (Sport Lightweight). Then again, the carbon parts appear to be add-ons, not replacements for existing components.

The white-bodied roadster has been treated to a new front bumper with more aggressive carbon fiber intake embellishers and a new splitter, while the hood is now vented and features a central intake scoop. Down the side, the fender badges have been refinished in gloss black to match the big new wheels, and the side skirts have aero extensions for more menace. The mirror caps have also been replaced.

These items and the rebadged grille include orange accents to make them stand out even more.
