Subaru is a Japanese automobile manufacturer owned by Fuji Heavy Industries (FHI). Subaru cars are multiple winners of various auto races, and the brand itself is often the standard and benchmark for other automakers.
Subaru uses a four or five letter code to label its engines.
- The first letter is always Latin E (from engine) (before the FB series).
- The second letter indicates the engine family.
- The next two indicate the displacement (or version, before 1989).
- The fifth character is optional and indicates the version, for example: turbo, DOHC, Fuel Injection, etc.
