This concept car was kept in secrecy until 2020. Under the cover there is a Volkswagen XL carbon fibre monocoque chassis and the car could have been powered by a high-revving motorbike engine. The 1:1 hard model of the possible future 904 looks similar to the Porsche 918 supercar from the front and to the F. A. Porsche designed 904 Carrera GTS supercar from the side. It looks just perfect!
