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.[1]

The development of the series began in the late 1970s, when Toyota wanted to develop a completely new engine for the Toyota Tercel, the successor of Toyota's K engine.[2] The goal was to achieve good fuel efficiency and performance as well as low emissions with a modern design.[3][4] The A-series includes one of the first Japanese mass-production DOHC, four-valve-per-cylinder engines, the 4A-GE, and a later version of the same engine was one of the first production five-valve-per-cylinder engines.[5]

Toyota joint venture partner Tianjin FAW Xiali produces the 1.3 L 8A and resumed production of the 5A in 2007.
