The GV4s also became powerful enough to contest for overall wins in the 24 Hours of Le Mans, with Oreca Dallaras running the GV4 finishing fifth and sixth in as well as an overall victory for Doran Lista at the Rolex 24 at Daytona the same year. The engine's reliability record at Le Mans was still patchy and, while it could challenge for the pole in Domes and Dallaras, the engine rpms had to be reduced to ensure it survived the race.
