From wikipedia:

The Renault RE60 was a Formula One car designed by Bernard Dudot and Jean-Claude Migeot and was raced by the Renault team in the 1985 season. A modified version of the car, RE60B, was introduced at the French Grand Prix but this failed to generate any better results. The cars were driven by Patrick Tambay and Derek Warwick who had also driven for the team in 1984. The best results were 2 third places for Tambay in Portugal and San Marino, the 2nd and 3rd races of the season. Renault had decided that funding a Formula One team was not worth attempts developing technology for their road cars and the bad PR generated by their continuous failures to be competitive had been the final straw.

The car was an evolution of the RE50 raced by the team in the 1984 but proved less successful than its predecessor with Tambay scoring the last two podium finishes for the team that pioneered the turbo engine in Formula One back in 1977. While the team and the Renault turbo engine had ultimately been successful in winning races they had never won either the constructors nor drivers’ championships in F1.
