IC Bus (originally IC Corporation) is an American bus manufacturer. Headquartered in Lisle, Illinois, IC is a wholly owned subsidiary of Navistar International. Established in 2002 by Navistar through the reorganization of subsidiary manufacturer American Transportation Corporation (AmTran), IC currently produces school buses and commercial-use buses for multiple applications.The IC company name stands for "Integrated Coach", alluding to how the vehicles are nearly completely assembled under a single corporate structure. For all vehicles, the body and chassis are assembled within the same manufacturing facility; the latter is designed by parent company Navistar (prior to 2015, Navistar included the engine). While using a chassis and hood shared with International-brand trucks, IC Bus vehicles have separate badging. [Wikipedia]
