EyeSight

Starting May 2008, the Japanese-spec Legacy could be fitted with a new safety feature called EyeSight. It consists of two cameras, one on each side of the rear-view mirror, that use human-like stereoscopic vision to judge distances and generally keep tabs on the driver. The system helps maintain a safe distance on the highway, warns the driver during unintended lane departure, emits a wake up call should everyone else pull away from the traffic lights, and keeps an eye out for pedestrians. SI-Cruise has been integrated into the EyeSight feature as a driver safety aid.

According to the Subaru Owners on-line newsletter dated March 2008, Subaru was planning to introduce the diesel Legacy and Outback models in the U.S., stating they were "...currently making modifications to the diesel so it meets the more stringent U.S. standards. Subaru diesel models should be domestically available in two to three years." However, there has yet to be a diesel version of any Subaru model introduced into the U.S.
