This custom Beetle Cabriolet was built by Richard Webb at RJ Volks Performance in the UK. The convertible features a custom tube chassis, 4-link rear suspension, and weighs 1888 lbs with a 33/67 bias. In the back of the car sits a turbocharged 2600 cc flat-four controlled by a FuelTech FT600 EFI system. No word on current power numbers but a smaller displacement version made 890 horsepower to the wheels on 2 bar (29 psi) of boost and methanol fuel (dyno video below). Watch Richard compete at Doorslammers 2019 below or view more videos of the Beetle on RJ Volks’ YT channel.
