The 20Cup features a front-mounted air intake, with air evacuated laterally ahead of the front wheels. On the lower body sides, profiles serve as an aerodynamic diffuser to promote maximum bearing on the front axle. The engine is the result of cooperation between the PSA Peugeot Citroen and BMW Group. The turbo-charged 4-cylinder gas engine with direct injection has sixteen valves and two overhead camshafts. The version shown develops a maximum power of 170 bhp and a maximum torque of 325 lb-ft.
