Taking advantage of the longitudinal FF layout unique to horizontally opposed engines, the EA52 was developed as Japan's first proper engine for small front engine front wheel drive passenger cars. This lightweight, compact, and low vibration engine fully showcased the benefits of a horizontally opposed engine.
