The 1991 Toyota Corolla was virtually identical to the 1990 Corolla, when the model got a more powerful engine and a new entry-level version of the sedan. The 1991 Toyota Corolla came in many body styles with several trim levels. The sedan came as a base, DX or LE. The wagon was available as a DX or SR5. The coupe came as a SR5 or GT-S. All Corollas came equipped with a DOHC, 16-valve inline four-cylinder engine. The sedans, wagons, and SR5 coupe had a 102-horsepower engine and the GT-S had a 130 horsepower. Fuel economy is about 22 to 33 mpg, depending on the engine. Owners of the 1991 Corolla complain that the car is underpowered and performs even worse when the air conditioning is running. Still, they tend to praise the car for being reliable and long-lasting, and many have been driving them trouble-free since the car was new.
