Super 1600 is a rally car formula that is primarily used in the Junior World Rally Championship, as well as various national rally championships. Any automobile manufacturer that has a suitable road-going production model in its range may develop a specification for use in this formula. It was devised by the Fédération Internationale de l'Automobile (the international governing body of motorsport) in 2000 and first saw competitive use in 2001. Super 1600 is intended to provide a young driver's entry point into international rallying, and the World Rally Championship in particular.

Most FIA-approved rally car formulae are in some way production-based, from Super 1600 to World Rally car specification. This necessitates a process of homologation in which a suitable production road car design is modified within the limits of a formula's technical regulations. Such changes may include modified or entirely new parts in the engine, gearbox, suspension, bodywork and so on. In the Super 1600 formula, "suitable" is defined as a passenger car that has one driven axle (two-wheel drive) and a 4-cylinder engine that is of naturally aspirated configuration with a maximum volume of 1640cc. At the time of homologation, the car must currently or have previously been in serial production.
