The Toyota Celica GT-Four or Turbo All-Trac (ST165) was the most powerful Celica of the fourth generation. It had a 2.0L four-cylinder 3S-GTE engine that made 190hp and a five-speed AWD transmission that delivered that power. Toyota sent 77 of these cars to the U.S. in 1987 branded as 1988 models. They are identifiable with white paint and white wheels and bare the badging on the side "IMSA GTO CHAMPION." The car celebrates the IMSA GTO victory for Toyota. All other GT-Fours followed until the end of the generation in 1989. The GT-Four would see another generation starting in 1990 with the ST185 or fifth iteration of the Celica GT-Four.
