In 1971, the stylish A310 was designed to be the replacement of the famous A110 (which was a common sight in French rallies). The first version of the A310 was powered by a four cylinder Gordini engine. Larger and heavier than the A110, the A310 struggled to be competitive, and for a few years the two models would compete side by side. In fact, Renault won the 1973 World Rally Championship with the A110. For the A310, the fix to get better results came with the restyled second series which was now powered by the more powerful PRV V6 engine. The A310 V6 was homologated in Group 4 in 1977 where it won the French Rally Championship in the capable hands of Guy Fréquelin.

When Group B came along in 1982, the A310 V6 had already fallen out of contention. Renault had since replaced it for competition with the 5 Turbo. However, the A310 V6 (which was still in production) was nonetheless re-homologated in Group B. Similarly to the BMW M1 Rallye, the A310 V6 only saw action in the WRC when it overlapped with the French series (such as in Monte Carlo and Tour de Corse). The car performed rather abysmally with a high percentage of retirements. Its last known appearance in the Group B-era WRC was in the 1985 Monte Carlo rally (2 DNFs).

The Alpine A310 is a sports car built by French manufacturer Alpine (subsidiary of Renault), from 1971 to 1984. The V6 version replaced the 4 cylinder from 1977 and on. Produced a total of 9276 units, it is a far cry from being an homologation special but it is arguably considered one of the more stylish cars of the decade. It is note to mention that the PRV V6 engine it employed was also used in the ill-fated DeLorean DMC-12.
