With beautiful, sweeping bodywork as a canvas, there is certainly going to be no shortage of aftermarket opportunities to customize the Mercedes-AMG C63 S Estate. This latest project is courtesy of German tuners at performmaster, who not only modified the exterior, but gave the C63's twin-turbo V8 4.0-liter engine a massive power boost. Rolling off the production line, the stock motor was rated at 476 HP and 479 lb-ft of torque; after the installation of a PED tuning module and a few other tweaks, performmaster was able to extract 28% more power, bringing the top end speed to 193 mph and horsepower and torque to 612 and 620 respectively. After all is said and done, sprint time dropped from 4.1 seconds to 3.8 seconds with a few subtle sports body kit pieces to match, comprised of a front lip, side skirts, and rear diffuser. Check out their work below and let the performmaster team know if you want a similar look.
