In the past, IVECO, the world's largest bus manufacturer, had various brands in the bus sector. Until 2013, this included the Irisbus brand under which IVECO marketed its buses. In 2006, IRISBUS launched its brand new Low Entry coach series. It is based on the CROSSWAY chassis and has a low floor between the doors and a high floor at the rear.
Intended for mixed and versatile use, these new coaches will now find many opportunities for suburban and intercity operations in OMSI, the Omnibus Simulator.
