Dubbed the Turbo Evoluzione, it was a homologation special on which the new Group A racer was to be based. While the 500 road going machines were built, the Alfa Corse engineers set about developing the competition car.

The production road car was stripped down to a bare shell and a roll-cage was installed. An aggressive body-kit was fitted with purpose built bumpers, skirts and wider wheel arches. One of the things that set the Evoluzione apart from the regular 1.8i Turbo was its sleeved down four-cylinder engine. By bringing the displacement back to 1,762 cc, the turbocharged engine fitted in the three-litre category taking the 1.4 equivalency factor into account. In Group A trim, the engine produced around 280 bhp.

Ahead of the 1987 season, Alfa Corse produced six examples to compete in the World Touring Car Championship. Among the drivers signed for this high profile campaign were Jacques Laffite and Michael Andretti. Unfortunately, the 75 Turbo Evoluzione proved no match for the dominant BMW M3, which had a superior chassis and around 30 additional horses. A third place in the Tourist Trophy at Silverstone for Giorgio Francia and Nicola Larini was the best result in the 1987 World Touring Car Championship. Due to the disappointing results, Alfa Corse ended the factory effort before the end of the season.

Development of the cars did continue and by 1989, power was up to a more competitive 390 bhp. The changes also included even wider wheel arches and the addition of a rear wing. This allowed the 75 Turbo Evoluzione to compete with considerably more success in national championships in private hands. These later cars were at times referred to as 75 Turbo Evoluzione IMSA, for which there is no logical explanation. IMSA was an American sanctioning body and the 75 Turbo Evoluzione racing cars were neither designed to comply with IMSA regulations nor did they ever compete in North America.

Raced well into the 1991 season, the 75 Turbo Evoluzione won the Italian Touring Car Championship in 1988 and it also scored back to back victories in the Giro d'Italia in 1988 and 1989.
