The Orion VII was a line of low-floor transit buses available in 30' rigid, 35' rigid, and 40' rigid lengths manufactured by Orion Bus Industries between 2001 and 2013 in three generations. The conventional powered buses, either with longitudinally-mounted diesel or natural gas engines, used a T-drive transmission coupling. A series hybrid variant powered by a diesel-driven generator was also available. The Orion VII replaced the fully low-floor Orion VI and high-floor Orion V buses, and was manufactured until its parent company DaimlerChrysler withdrew from the transit bus market in 2013.
