Iveco France has cooperated with the Carnot institutes Energies du Futur (CEA- LITEN) and IFPEN Transports Energie within the framework of  the ElliSup project, since 2009. The aim was firstly to offer rechargeable hybrid electric vehicles to be used as Citelis buses, under the Irisbus Ivedo brand.
The project is going on. It has already made it possible for Iveco-France to market a first range of hybrid Citelis buses in 2011, enabling a reduction in fuel consumption and CO2 emissions of approximately 35%.
Now R&D activities are focused on the development of plug-in hybrid buses and all-electric buses recharged at terminals in order to get a full-electric operating mode 20 hours a day, with no interruptions due to charging time.
