The Renault 5 Turbo or R5 Turbo is a sport hatchback automobile launched by the French manufacturer Renault at the Brussels Motor Show in January 1980. The car was primarily designed for rallying, but was also sold in a street version.

Rallying is a wide-ranging form of motorsport with various competitive motoring elements such as speed tests, navigation tests, or the ability to reach waypoints or a destination at a prescribed time or average speed. Rallies may be short in the form of trials at a single venue, or several thousand miles long in an extreme endurance rally.
