Subaru introduced a facelift for its mid-size lineup, the Legacy, in 2006, and, along with the sedan, it improved the station wagon version as well.
While its famous Impreza sibling just received its second facelift and started to look like a car, the Legacy didn't suffer from that since it was designed well from the start. Subaru noticed that it matched the design with the customers' preferences and didn't want to spoil the success with a new line or heavily improved headlights. Instead, it made slight aesthetic changes and decreased the number of engines available, making it easier to build.
Subaru took the "101 on how to facelift a car" and started to apply it on the Legacy, but it didn't read it all. It changed the headlights, which became softer on the edges, the bumpers that received fog lights, and the taillights, which received wider clear lenses for the reversing lights. Also, for specific versions, it added two exhausts.
Inside, the carmaker improved the sound system and offered an in-dash CD-changer unit. That meant that the center stack had to be redesigned and, since the design team had to work, it did it for the entire range. The team also made a few modifications on the instrument panel, which received red rings around the dials, as a reminder that the car was not just a regular "go-to-school" vehicle.
Under the hood, Subaru dropped some unwanted versions and introduced a 2.0-liter turbo-diesel flat-four engine. The European customers were happy about that since they asked for an oil-burner for years. The turbocharged 2.0-liter was deleted. Only the 3.0-liter naturally aspirated unit could go past the 200 hp barrier, which was not very popular on the European market but in high demand for U.S. customers.
