The Toyota CORSA / Tercel is a subcompact manufactured by Toyota from 1978 to 1999 across five generations, in five body configurations sized between the Corolla and the Starlet. Manufactured at the Takaoka plant in Toyota City, Japan, and sharing its platform with the Cynos (a.k.a. Paseo) and the Starlet, the Tercel was marketed variously as the Toyota Corolla II—sold at Toyota Japanese dealerships called Toyota Corolla Stores—and was replaced by the Toyota Platz in 1999. It was also known as the Toyota Corsa and sold at Toyopet Store locations. Starting with the second generation, the Tercel dealership network was changed to Toyota Vista Stores, as its badge engineered sibling, the Corolla II, was exclusive to Toyota Corolla Store locations.
The Tercel was the first front-wheel-drive vehicle produced by Toyota, establishing a layout and frame that was later used in other popular Toyota models. For example, the Toyota Corolla E80's frame is similar to the AL20 Tercel's frame. Also, Toyota designed a new A engine for the Tercel, attempting simultaneously to achieve good fuel economy and performance and low emissions. Choice of body styles increased as well, with the addition of a four-door sedan.
The name "Tercel" derives from the Latin word for "one third" as the Tercel was slightly smaller than the Corolla—much the way "tiercel" refers to a male falcon, which is one-third smaller than its female counterpart. All Tercels were assembled at the Takaoka factory in Toyota City, Aichi or by Hino Motors in Hamura, Tokyo. Hino assembled the third generation Tercel from 1986 – 1990 for the two–door and some three–door models.
