The Audi Mid-Engine Supercar Concept We Wish Made It To Production

At the 1991 Tokyo Auto Show, Audi unveiled the Avus Quattro concept. It showcased a 6.0-liter W12 engine, estimated at 509 hp. The car used hand-beaten aluminum panels about 1.5 mm thick, keeping weight around 2,755 lb. With three lockable differentials, rear-wheel steering, Quattro AWD, and a 6-speed manual. The rear-window engine was a wooden facsimile, as the official W12 was still under development. Audi never planned production; Avus served as a concept to guide future ideas. Rumors persist of up to $12 million for a working version. Mattel released Hot Wheels versions, giving the design broader exposure.
