Cups no longer carry the proper paperwork for registration. In July 1985, the Europa Cup model appeared; this limited edition model was intended for a single-make racing championship, and 69 cars were built (54 in 1985 and 15 more in 1987). In September 1985 the turbo model (D 501) followed, which increased the power of the PRV unit to . V6 Turbo It was introduced in September 1985. With a larger rear spoiler grille to improve cooling. The Cx increases from 0.28 to 0.30. Like the Renault 25 V6 Turbo, the GTA benefits from the 2.458 cc V6 PRV turbocharged engine. Sales of the naturally aspirated model were always sluggish, but with the more powerful turbo, things picked up considerably. At the 1986 Birmingham Show, the right-hand-drive version was presented and UK sales, as the Renault GTA, commenced. In early 1987 a catalyzed version appeared, with fifteen fewer horsepower. This meant that the Turbo could finally be sold in Switzerland and later in other European countries such as Germany and the Netherlands when they adopted stricter legislation.

The Mille Miles, a limited edition of 100 cars, also featured a special dark red metallic paintjob, polished aluminium wheels, and a large silver-gray triangular stripe with the Alpine "A" across the left side of the front. In February 1990 the limited edition Le Mans arrived, this car had a more aggressive body kit with polyester wheel arch extensions and a one piece front with smaller headlights. Wheels were 3 piece BBS style produced by ACT, 8x16" front & 10x17" rear. Many of these changes were adopted for the succeeding A610. The regular V6 GT and V6 Turbo ended production during 1990, while the Le Mans version
