Toyota introduced the Celica GT-Four (Classified as ST165 to distinguish from the standard model ST160) onto the Japanese market in October 1986. With full-time all-wheel drive, including an electronically controlled central locking differential, and a turbocharged version (3S-GTE) of the GT-S 2.0 L engine producing 142 kW (190 hp)
The Toyota ST165 chassis design was quite acclaimed for its time, and chose not to make any drastic suspension changes for the AWD GT-Four. The front suspension comprises MacPherson struts with an anti-swaybar and strut tower brace, while the rear employs struts with a trailing link and twin lateral links per side plus an anti-swaybar.
Toyotaâ€™s entry in the World Rally Championship during the late 1980s was the all-wheel drive version of the popular Celica sports car. Badged the GT-Four in road-going form, the ST165 Celica was powered by Toyotaâ€™s advanced 3S-GTE turbocharged 2-litre engine with Bosch L-Jetronic fuel injection and four-valves per cylinder, developing close to 200 Hp.
Debuting in the 1988 Tour de Corse, the Celica didnâ€™t achieve success until Rally Australia the following year. For the first time a Japanese manufacturer enjoyed real success in Group A, leading the way for a new generation of rally cars from Mazda, Mitsubishi and Subaru.
