Audi Quattro-set body formed the shape of a wedge. Elongated openings on the rear pillars, rear spoiler and wide sills and fenders fit a clear hit-sporty character. In front of the body style, model, referred to the 200th

From the moment it is put into production - a month after the Geneva launch - was an instant competitor to the best sports car brands. And just as quickly proved its value in the raids - including the Audi Quattro driven by the great Finnish driver Hannu Mikkola, and also by the French champions Michele Mouton placed the steering wheel at the forefront. After the first two seasons of sports Audi Quattro was one of the best rally cars of the world.

In racing events, especially played on bad roads or off-road Quattro was a winning one.

Audi Auto Union company needed these successes - she wanted to refer to the magnificence of their sports cars of the thirties. It worked. The Audi was again loudly. In developing the design of the Quattro thought about the successes of sports racing events, ie, where they can compete in a series produced cars, which also made it the car of a sports utility.

Construction of the car was done very carefully. Already in April 1977 to mass-produced Audi 80 chassis fitted with a prototype 4-wheel drive.

Between the turbo and the head was used Intercooler, lowering the temperature from 130 to 80 ° C. In addition to the mechanical fuel injection Bosch K-jetronic (civilian version and early versions of the rally) was used in Japanese, contactless electronic Hitachi precisely regulates ignition timing of the mixture. In 1987, increased capacity of the drive unit to 2,226 cc, and two years later was replaced with a turbocharged engine having four valves for each of the five cylinders with a capacity of 220 hp, in which was equipped with a Quattro until the cessation of production in 1991
