Iveco Bus (formerly Irisbus) is a bus manufacturer, with headquarters in Lyon, that belongs to the industrial group CNH Global through its subsidiary Iveco, based in Turin (Italy). Iveco-bus is now only a brand division of IVECO which is a company incorporated under Italian law and listed on Borsa Italiana.
Iveco Bus was formed through the merger of the bus and coach divisions of Fiat Industrial, Iveco and Renault in January 1999, with Ikarus Bus added in late 1999. The Ikarus Bus division was sold off in 2006 to Hungary's Műszertechnika group.
The company is based in Lyon, France with offices in Turin, Italy, Watford and Mainz. Buses are developed in one of two R&D centers, one in Italy and one in Switzerland. The engine which powers Irisbus Buses was developed in Italy by Fiat Powertrain Technologies, Turin, Italy.
The Irisbus name was retired and now the division is a branch of Iveco, rebranded as Iveco Bus in May 2013, after a reorganization plan. All new buses are sold under the IVECO brand, as are all the other vehicles produced by the group.
