Radial Motion and Bespoke Engineering enjoy testing their custom three-cylinder engines in Volkswagen vehicles. One of their first projects was a 1972 Super Beetle called “Zombug” powered by their naturally aspirated 2.0 L three-cylinder making 150 hp. After that the companies began working on a 1976 VW Kombi Type 2 postal van. After restoring the body and putting a fresh coat of red paint, they installed another of their 2.0 L three-cylinder radial engines. Radial Motion makes an adapter allowing the motor to use a VW transaxle.
If you are wondering what the engine sounds like. Take a listen to one in a Meyers Manx on the beach.
