It was previously powered by an aircooled 2109 cc flat-four. In 2016 the engine was severely damaged. Russ made the decision to swap it for a turbocharged 1.8 L 20v (APX) inline-four from a 2000 Audi TT Quattro. The engine produces 289 horsepower and 305 lb-ft of torque tuned by Chris Roylance at Volks Workshop.
