The Legacy B4 was powered by a 1.8-liter EJ18 horizontally-opposed four-cylinder engine, renowned for its smooth operation and durability. The engine options varied by market, with both naturally aspirated and turbocharged versions available. The turbocharged engine, particularly popular in Japan, delivered a substantial power boost, making the Legacy B4 a capable and surprisingly quick car for its time.

It was a comfortable and spacious sedan with a well-appointed interior, featuring a user-friendly dashboard and comfortable seats. Although the Legacy B4 was primarily aimed at the Japanese market, it was also exported to several other countries, including the United States and Europe. The Legacy B4 marked a turning point for Subaru, establishing the brand as a serious contender in the mid-size sedan segment. Its success paved the way for further development of the Legacy line, which has become one of Subaru's most enduring and popular models. Today, the Legacy B4 is considered a classic Subaru, appreciated for its reliability, handling, and enduring appeal.
