Which 1991 Audi concept car featured a W12 engine and quattro all-wheel drive?

The 1991 Audi concept car that featured a W12 engine and quattro all-wheel drive was the Audi Avus quattro.

Audi presented the Avus quattro at the Tokyo Motor Show in October 1991. Its name referred to Berlin’s Avus racing circuit, linking the concept to Auto Union’s streamlined racing heritage. The car’s dramatic body was designed to showcase lightweight aluminum construction and a futuristic mid-engined layout.

The planned powertrain was a 6.0-liter W12 arranged as three four-cylinder banks, with an intended output of roughly 500 horsepower. The engine was connected to Audi’s quattro permanent all-wheel-drive system. The Avus remained a concept rather than entering production, and its proposed W12 technology did not reach Audi customers until the A8 6.0 W12 quattro arrived in 2001.

A common mix-up is Audi’s later Le Mans quattro, unveiled in 2003 and related to the R8’s development. The Rosemeyer and Nuvolari quattro were also later Audi concepts, not the 1991 W12 Avus car.
