Audi returned to the DTM for 1991 with a slightly updated V8 quattro Evo. Hans Joachim Stuck would lead the squad with the #1 car, though a young upstart new to the Audi brand if not the series was Frank Biela.
Having had quattro deemed an "unfair advantage" and thus outlawed in Trans-Am in 1988 and IMSA GTO racing in 1989 for its on-track dominance, Audi Sport turned to the German DTM series.
Built on the former RAF Silverstone bomber station, the circuit hosted the inaugural round of the Formula One World Championship in 1950 and has remained one of the sport's defining venues ever since.
