The Audi Sport quattro is a sports car from Audi that was first presented in 1983 at the IAA in Frankfurt. It was based on the Audi quattro for the Rally Sport develops and from autumn 1984 to the summer of 1985 in a number of only 220 units for the required FIA - homologation of Group B produced.
After Audi entered the rally in 1981, the works team won the makes world championship with the Audi quattro as early as 1982. In 1983 the world championship driver title followed by Hannu Mikkola . But the competition grew stronger over time. The rally quattro, which was built on the basis of a production car, could no longer keep up with pure racing machines such as the Peugeot 205 Turbo 16 with a mid-engine. As early as 1983, Audi decided to design a new vehicle - the Sport quattro, also known as "the short one". The Sport quattro looks quite similar to the quattro from the outside, but apart from their name, the two don't have much in common. In addition, Walter Röhrl was signed for the 1984 season . At Audi, he was mainly supposed to do development work.
The Sport quattro was presented to the public for the first time at the 1983 International Motor Show. Deliveries began in December 1984.
For the body, Audi was able to use the so-called modular system thanks to the large number of its models. The basis of the Sport quattro is the two-door Audi 80 sedan up to the B-pillar and the Audi quattro from the B-pillar . The Sport quattro is 320 mm shorter than the Audi quattro. The side doors come entirely from the Audi 80. The tailgate is made of fiberglass-reinforced polyester resin , as was also used for the front spoiler of the Audi quattro. Fenders, rear side panels, roof, bonnet, front and rear apron were manufactured and delivered by the Seger and Hoffmann company in Switzerland . These parts are made of multi-layer aramid fabric , epoxy resin and various additives. The manufacture and processing of this dimensionally stable, yet lightweight material also accounted for a large part of the overall costs of the Audi Sport quattro.
Never before have all the technical possibilities for increasing performance been used side by side in series automobile construction, as here. In addition to the exhaust gas turbocharger already known from the Audi 200 Turbo and Audi quattro , the Audi Sport quattro uses a cylinder head with four valves per cylinder. The displacement was reduced from 2.144 to 2.133 liters by reducing the bore from 79.5 mm to 79.3 mm. This was necessary in order to remain below 3 liters of displacement despite the so-called "turbo factor" of 1.4 specified for turbo engines in the competition :
- 2.144L × 1.4 = 3.0016L
- 2.133L x 1.4 = 2.9862L
This was important because the regulations allowed vehicles with a displacement of less than 3 liters to weigh less than 1000 kg. Corresponding to the function of the Audi Sport quattro as the planned winning car on national and international rally slopes, the overall concept of the engine was designed so that a further increase in output to 450 to 500 hp was relatively easy to achieve for sporting use.
To compensate for the extra weight of the four-valve cylinder head and the larger turbocharger, the engine block was made of aluminum. In addition, a new, fully electronic injection system was used for the first time in a turbo engine from Audi in the Sport quattro.
The engine of the Audi Sport quattro achieved an output of 225 kW (306 hp) and 350 Nm of torque. The five-cylinder four-valve engine with K27 turbocharger from KK&K allowed a boost pressure of up to 2.04 bar.
The Audi Sport quattro had a very extensive range of standard equipment. Additional equipment was not provided for the Sport quattro ex works.

The Sport quattro was freely available in the following colors:
- Tornado red (classic Italian racing color)
- Copenhagen blue (classic French racing color)
- Malachite green (classic English racing color)
- Alpine white (as a replacement for the classic German racing color silver)
For the then Audi board member Ferdinand Piëch , two copies were made in black on request.
The Audi Sport quattro was produced in a number of 220 units, for a further 4 individual parts were produced. The production was divided as follows:
- 4 pieces pre-assembled in individual parts, which were not completed (specification Audi Motorsport)
- 134 pieces in tornado red
- 48 pieces in alpine white
- 21 pieces in Copenhagen blue
- 15 pieces in malachite green
- 2 pieces in black
89 of the vehicles in the color tornado red went on sale. Six vehicles were prototypes, 19 were test vehicles and 20 were used as rally vehicles by Audi Motorsport itself.
The Audi Sport quattro was offered from December 1984 for a price of 195,000 DM and was therefore the most expensive German production vehicle at the time. In comparison, a Porsche 911 Turbo was only half the price, namely 100,000 DM. On January 1, 1985, the price was increased to 203,850 DM.

Around 170 units of the Audi Sport quattro were sold to private individuals, but its real purpose was racing in the World Rally Championship . It made its first appearance there at the Corsica rally in 1984. However, the Sport quattro S1 initially proved to be relatively unwieldy. The engine was also struggling with temperature problems, but these were resolved over time. At the Ivory Coast Rally in 1984, Stig Blomqvist drove him through mud and dust to overall victory and thus to both world championship titles for himself and Audi. In 1985 the Sport quattro S1 contested its first full rally season. However, the signs of the times had already turned against Audi. The competition's new, thoroughbred Group B racing cars were clearly superior to the Sport quattro, which was derived from a street car.
But Audi continued to develop a total of 20 copies of the Sport quattro, but these were not based on the S1 version. Taking full advantage of the FIA regulations for evolutionary versions, the Sport quattro was given wings and spoilers and was then called Sport quattro E2. These spoilers gave it sufficient downforce both at high speeds and when cornering. The Sport quattro E2 made its debut at the beginning of July 1985 at the Olympus Rally (then an aspirant competition for the 1986 World Rally Championship) in the USA, where Hannu Mikkola drove it to an impressive overall victory. Walter Röhrl then celebrated the only victory of a Sport quattro E2 in a world championship run at the 1985 San Remo rally. After an accident at the Rally Portugal 1986, in which 3 spectators were killed and 33 injured, Audi temporarily withdrew from the World Rally Championship.
In 1987 Audi brought the “short one” back to the racetrack. In the most powerful version ever built by Audi itself. The Audi Sport quattro E2 Pikes Peak was to write motorsport history together with Walter Röhrl. The vehicle has been further improved aerodynamically compared to the "normal" E2. The engine also got additional power. According to Audi, Walter Röhrl now had 598 hp available. Röhrl contested the Pikes Peak International Hill Climb in Colorado ( USA ) with this vehicle . Audi won this hill climb, known as Race To The Clouds , in 1984 (Mouton / Pons, class win), 1985 (Michèle Mouton, overall victory) and 1986 (Bobby Unser senior, overall victory). But in 1987 the competition should be particularly strong. In the end, Walter Röhrl won with a 7 second lead over his strongest competitor Ari Vatanen in a Peugeot 205 T16 E2 , who had to struggle with technical problems shortly before the finish. Röhrl was also the first driver to win on Pikes Peak in less than 11 minutes. 10 minutes and 47.85 seconds represented a new course record. To date, this record has not been beaten by any other vehicle with a front engine.
After this hill climb on gravel and a few half-hearted attempts with the Audi 200 quattro, Audi withdrew from rallying and soon concentrated on circuit racing. After the FIA end had in 1986 banned the group-B "Monster" from the World Rally Championship, some sports took quattro S1 and E2 still several years in the Autosport Rallycross successfully in many races in part, for example, under the Austrian Herbert width Eder . The most potent of them had highly developed engines for the short sprint distances that are common here, the power of which was somewhere between 650 and 700 hp.
The maximum engine output and the acceleration from 0 to 100 km / h in seconds are specified.
- Audi Sport quattro: 225 kW (306 hp); 4.9 s
- Audi Sport quattro S1 (rally version): 331 kW (450 PS); 3.5 s
