The Audi S1 and his friends - The Group B Monsters (Video)
Group B, 1982-86: insane times, cars and spectators, check out this recently revealed compilation:

The Group B referred to a set of regulations introduced in 1982 for competition vehicles in sportscar racing and rally racing regulated by the FIA. The Group B regulations fostered some of the quickest, most powerful and sophisticated rally cars ever built. However, a series of major accidents, some fatal, were blamed on their outright speed. At the Rally Portugal in 86, three spectators were killed and over 30 injured after Joaquim Santos lost control of his FORD RS200. After the death of Henri Toivonen and his co-driver (Lancia Delta S4) in the Tour de Corse a few months later, the FIA disestablished the class after only four years. The short-lived Group B era has acquired legendary status among rally fans.
The Sport Quattro was Audi's first real GROUP B car. The chassis was much different as compared to the original. Note that 320mm has been chopped out of the car between the door and rear wheel. AUDI also wanted to improve weight balance by moving the batteries, oil coolers and radiators into the rear of the car. The end result was a 52% front/48% rear weight balance, but still with a high polar moment (weight far from the center of gravity). Specifications:
- Homologation: 1.5.1984 (B264) S1 1.7.1985
- Engine: 2133cc Alloy Inline 5 cylinder
- Compression Ratio: 8.0:1
- Turbocharger: KKK-K27 @ 17.4psi
- Fuel System: Bosch LH Motronic
- >600BHP Version: 0-62mph in ~2.5 seconds
The 1984 season was Audi's most successful year in rallying. Stig Blomqvist's sideways driving style plus the introduction of the short-wheelbase, more powerful (450+ hp) and more advanced (six-speed transmission, kevlar bodiwork) Sport Quattro combined to take both titles for the 1984 season. However, the 1984 season saw a new challenger to Audi's crown: Peugeot launched their brand new 205 T16 in Corsica for the 1984 Tour de Corse rally. The new 205 differed from the Quattro in several key respects: it was rear-engined, it had a space frame, and it was a generally smaller car with less weight. Peugeot driver Ari Vatanen nearly won the 205's first rally, except a crash prematurely ended his rally. The Peugeot caused enough concern that the AUDI team managers sent messages back to the engineers in Ingolstadt, reminding the engineers to keep up development, and not to be complacent with the current success.
The radical Sport Quattro S1, introduced at the 1000 Lakes rally in 1985, proved to the rally community that AUDI was very serious in its attempt to regain its previous form. The S1 had more power than any other rally car in history, reaching over 600 horsepower in 1986, and it had huge wings to aid with traction on faster stages. The Quattro in its various iterations competed for four and a half years, winning four championships, and changing the face of rallying forever.
Walter Röhrl described the visceral experience of driving one of the most iconic Group B supercars, the Audi Sport quattro S1, in Reinhard Klein's Rally Cars book: "It must be the most extreme car I have driven in my career. First there was the sheer power. We had 535 bhp for Sanremo in 1985. That meant plenty of power everywhere and at any speed.
"Then there was the sound. The 5-cylinder in-line engine had a very unique sound not comparable to any other. It was the sound of sheer unlimited power and not like most of the other engines, a high-rev screamer. We also had the new wastgate system operating in Sanremo and the engine was always blowing off pressure and banging explosions into the countryside. No car was like that.
"The most demanding thing was the tremendous power and the anti-lag system. The engine pulled with full boost and 535 bhp from about 3000 revs onwards. There was not much influence on the power with the accelerator pedal, if you lifted off you lost all the power. It was all or nothing and I went for all on the 1985 Sanremo Rally."
