The Audi Quattro has an innovative and disruptive ring to its name. With is all wheel drive system, it changed the historic course of Rally racing, and just a few years later also for road-legal production cars. The Audi Quattro Sport S1 was introduced just three years after the Audi Quattro was born. Apart from its huge overhangs and large rear wing which created a monster-like look, the Audi Quattro Sport S1 also featured early experimental versions of automatic dual clutch gearboxes which inspired today's direct-shift-gearbox or Porsche's Doppelkupplung. Audi Sport Quattro was a fantastic innovation for racing and road cars, carrying legends like Walter Röhrl, Stig Blomqvist, Bobby Unser and others.
