In 1990, Toyota released the fifth generation of the Celica. The new car was markedly different in styling, featuring a very rounded appearance. The engines were also revised across the board. Anti-lock breaks were standard in the 1990 Celica, and the high-end All Trac was available with even more options.

The ST coupe's engine was downgraded to a 1.6-liter, with 103 horsepower. However, the GT and GT-S coupe and hatchback's engine was increased to 2.2 liter, and the 2.0-liter engine on the All-Trac was increased to 200 horsepower. Fuel efficiency was about 19 to 32 mpg. The convertible was not produced this year.

The 1990 Celica was criticized for being too curvy, which was not a common look among cars of that era. However, drivers today love the car's appearance because it is not outdated. Drivers also appreciate the car's superior cornering ability and typical Toyota longevity. Many drivers of the 1990 Celica have had to service the air conditioner, and owners complain that the back seat is very small.
