A Mercedes C63s AMG (W205) customized by U.S. tuner Weistec has set a new world record in its own class.
The team replaced the car’s stock turbochargers with custom Weistec W.4 Turbo ones. They have also considerably reworked the drivetrain by upgrading intake and exhaust, and remapping the ECU. Once finished, the German car has run the quarter-mile streak in 10.46 seconds, accelerating to 226.75 km/h (140.9 mph) as it did so.
The full list of modifications is actually much longer than this, but you would be better off just watching the video featuring the 900-horsepower sedan in action.
