Audi had imprinted its name in the Rally world with Quattro A1 and A2, which were based on Audi 80. But the challenge from competitors was piling up in 1984 as Lancia Delta S4 and Peugeot 205 T16 were creating problems for all-wheel-drive Audi Quattro. Audi launched the most aggressive version of its already successful model, it was called the Audi Sport Quattro S1 E2. It had newer transmission and a better engine with a revamped body. Despite all the hype and potential, S1 E2 only lasted a year and won only a handful of competitions. But it is regarded as the most important project that the Audi took which defined its future and made way for many technological advancements.



Originally based on Audi 80, the Sport Quattro S1 E2 was the Quattro on steroids. The revolutionary all-wheel-drive and newer dual-clutch transmission (PDK). Audi’s rally career was short-lived and spanned only over 5 years, but the technology they launched became the stepping stone for today’s portfolio. S1 E2 was the most powerful rally car ever produced and even had a unique recirculating forced induction system for instant power at lower rev limits. Many prominent figures and rally drivers branded the Quattro as the legend of Rally Racing. The car retired after just 1 year when group B was disbanded and later, a few concept versions were showcased.


Audi Sport Quattro S1 E2 was a 2 door coupe, based on a steel monocoque chassis supporting a Kevlar frame and an integrated roll cage. The car had a 50:50 weight distribution, high tensile strength, rigidity, and lightness. Despite a heavier engine, AWD drive system, and a fleshy transmission, the car weighed only 1050 kg.


Audi Quattro had an illustrious career over 5 years with victories in many competitions, but S1 E2 was on road for only a year and had limited appearances.

  • San Remo Rally in 1985.
  • Walter Röhrl won the Pikes Peak International Hill Climb in 1987 with an E1 S2.
  • Quattro S1 E2 also set a record of under 11 minutes at Pikes Peak International hill climb that stood for many years to come.
