Every time Subaru seems on the verge of entering the automotive mainstream, it takes a step sideways and goes its own way. But by every measure, the 2010 Subaru Legacy is a mainstream sedan — sized to compete with cars that are the best sellers in America. But the Subaru Legacy is still a Subie. Like every other Subaru, the 2010 Subaru Legacy comes with standard all-wheel drive and uses horizontally opposed "boxer" four- and six-cylinder engines. It may not look wacky anymore, but it's still a Subaru.
