In August 1985 the Celica was changed completely. It was an all-new vehicle with front wheel drive, a rounded, flowing body and new 2.0 L four-cylinder engines.
Toyota introduced the "ultimate Celica": the GT-Four (ST165) onto the Japanese market in October 1986. With full-time all wheel drive, including an electronically controlled central locking differential, and a turbocharged version of the GT-S 2.0 L engine producing 190 hp (142 kW) (3S-GTE), it immediately took its place as the flagship of the Celica range, and became the official Toyota rally car for all years of production. The GT-Four, with a revised viscous coupling central locking differential, began export in 1987 (1988 US model year) and marketed in North America as the All-trac Turbo. It was rated at 190 bhp (142 kW; 193 PS) and 190 lb·ft (258 N·m). The All-trac system was also offered for a limited time on the Camry, Previa, and Corolla in North America without the turbo.
The ST165 chassis design was quite acclaimed in its time. Toyota chose not to make any drastic suspension changes for the AWD GT4; 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.
The ST165 GT-Four made its World Rally debut in the 1988 Tour de Corse and finished 6th. The first victory came in 1988 Cyprus (non-WRC), and the first WRC victory in 1989 Rally Australia.
For the Japanese market this generation started with the 1S-iSU engine in the ST160 and 4A engine in the AT160. The 4A engine was terminated in August 1987 and the 1S-iLU engine was replaced by the 4S-Fi engine in the ST163 in May 1988. The 3S engine in various twincam forms was introduced in August 1987 in the ST162. The 3S-GTE turbo engine was also introduced at the same time in the all-wheel drive ST165 GT-Four. Two months later, a factory convertible (known as the ST162C) was offered with the twincam 3S-FE engine.
Non twincam models came in ST and SX trim levels. Models with the 3S-FE economy twincam came in the ZR trim level, including the convertible. Models with the 3S-GELU sports twincam came in GT and GT-R trim levels and lastly the turbo all-wheel drive model came in the GT-Four trim level.
The Australian spec Celica ST162 were the base model ST with 3S-FE engine offered as Coupe and Liftback, and the top of the line SX Liftback with 3S-GE engine.
In North America, the Celica was again available in ST, GT and GT-S trim as either coupe or liftback models, with the GT being offered as a soft-top convertible as well. The ST and GT came with a SOHC 8 valve, 2.0 L, 97 hp (72 kW) 2S-E engine from the Camry, but quickly changed to an all new DOHC 116 hp (87 kW) engine 3S-FE for the 1987 model year, also shared with the Camry. The GT-S was given a 135 hp (101 kW) version of the DOHC 2.0 L engine (3S-GE) featuring T-VIS. The All-Trac Turbo, an American version of ST165 GT-Four was added for the 1988 model year.
