The Toyota Celica GT-Four is a high performance model of the Celica Liftback that was produced from 1986 to 1999, with a turbocharged 3S-GTE engine, and full-time AWD. It was created to compete in the World Rally Championship, whose regulations dictate that a manufacturer must build road-going versions of the vehicle in sufficient numbers. These vehicles are referred to as "homologation special vehicles".
