The Toyota A Series engines are a family of inline-four internal combustion engines with displacement from 1.3 L to 1.8 L produced by Toyota Motor Corporation. The series has cast iron engine blocks and aluminum cylinder heads. To make the engine as short as possible, the cylinders are siamesed.

The Toyota Tercel is a subcompact car manufactured by Toyota from 1978 until 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 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 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 Vista Store, as its badge engineered sibling, the Corolla II, was exclusive to Corolla Store locations.
