Renault RE50

The Renault RE50 was the Formula One racing car with which the factory Renault team competed in the 1984 Formula One World Championship, driven by Patrick Tambay and Derek Warwick, with Philippe Streiff entered in a third car at the final race in Portugal. Its best results were three second places and two thirds, making it the first factory Renault not to win a Grand Prix in a season since the RS01 in 1978. The Renault EF4 turbo engine was said to produce 800 bhp, but fuel consumption was usually too high for either driver to challenge for more than second or third, with the 220 litre fuel limit and the ban on refuelling, and the carbon fibre tub proved fragile in crashes at Dijon and Monaco. Tambay took the team's only pole position at the French Grand Prix, Renault placed fifth in the Constructors' Championship with 34 points, and the RE60 replaced the car in 1985.
