Fifth generation / T180 Series (1989–1993)
The fifth generation Celica was introduced in September 1989 for the 1990 model year. The Celica received new Super Round organic styling, upgraded wheels and tires, more powerful GT-Four (US: All-Trac) with better cooling system, and for the Japanese market only, the 4-Wheel Steering (4WS) models. Toyota engineers claimed that the round styling and lack of straight edges increased strength without adding weight. The styling was later copied by other manufacturers. Japanese domestic market (JDM) models were now S-R, Z-R, GT-R, Active Sports (with active suspension), and GT-Four. The S-R and Z-R were powered by a 3S-FE engine, while the GT-R and Active Sports came with a 3S-GE. The 3S-GTE in the GT-Four features an air-to-air intercooler and CT26 twin entry turbo to eliminate exhaust gas interference. The JDM GT-Four has 165 kW (221 hp) and 304 N·m (224 lb·ft) of torque, a result of more aggressive ignition advance and ceramic turbine. The Full-time 4WD system in the GT-Four has viscous coupling limited slip center differential and Torsen rear differential.
