Subaru has released full details for its concept vehicle previewing the next-generation Legacy (Liberty) sedan due late next year. Appropriately named the Legacy Concept, the vehicle has made its world debut at the 2009 Detroit Auto Show. The concept features a 3.6L horizontally-opposed six-cylinder engine and the company's trademark symmetrical AWD system. Key characteristics include the distinctive front face and flared wheel arches. It sits on a larger 108.3in wheelbase than the current Legacy, which was implemented to maximize interior space and provide comfortable accommodations for four adults.
