The FIA World Rally Championship-3, or WRC-3 (formerly known as Production World Rally Championship, or PWRC), is a companion rally series to the World Rally Championship, and is driven on the same stages. WRC-3 is limited to production-based cars homologated under the R1, R2 and R3 rules. The series began in 2002, replacing the FIA Group N Rally Championship and it was for Group N cars. The cars used were modified road cars, often based on turbocharged, four wheel drive versions of standard small cars such as the Subaru Impreza WRX and the Mitsubishi Lancer Evolution, although a wide range of vehicles is homologated by the FIA for use in Group N. Apart from FIA sanctioned events, a lot of rallies at national levels are run under Group N.
