1991 Audi Avus Quattro
The Audi Avus quattro was a concept supercar made by the German car manufacturer Audi. It was first introduced at the 1991 Tokyo Motor Show. The Avus quattro had an aluminium space frame, which made it a lightweight and safe automobile. This second showing of the new aluminium architecture (after the quattro Spyder a month before) paved the way for the mass-produced aluminium A8 in 1994.
The bodywork on the Avus was designed by J Mays and inspired by Auto Union race cars of the 1930s, which featured unpainted aluminum bodies. The panels are made from polished aluminum that has been hand beaten and are only 1.5 mm thick.
The Avus quattro's engine was supposed to be a 6.0 L 60-valve W12 engine producing 509 PS (374 kW; 502 hp). The car shown at the Tokyo Motor Show, however, was fitted with a precision painted dummy, crafted from wood and plastic. Reason being, that at the time, its intended powertrain was still in development; Audi-made W12 engines were not available to buyers until 2001, on the 2001 Audi A8 6.0 W12 quattro. The Avus also features three lockable differentials, rear-wheel steering and a NACA-style duct mounted on the roof.
The Avus quattro is now on display at Audi's museum mobile in Ingolstadt, Germany.
