VDL hybrid Citeas for HEAG Mobilo Darmstadt


HEAG Mobilo in Darmstadt is operating three VDL hybrid Citea buses. The hybrid Citeas are the result of the German ‘Green Move’ development project, a collaborative initiative of transport company HEAG mobilo, Darmstadt University of Technology, Vossloh Kiepe and VDL Bus & Coach. ‘Green Move’ was initiated as part of the German policy to give certain regions a role model for the application of electric mobility. Rhein-Main, with Darmstadt as one of the main cities, is such a model region.

The objective of the ‘Green Move’ development project is to utilise serial hybrid technology in such a way that maximum savings in fuel consumption will be achieved, compared with conventional diesel buses. Also the emission of CO2, particulates and NOx will be reduced.

The Citea SLF-120/hybrid buses for HEAG mobilo have been built with components from renowned automotive suppliers. Vossloh Kiepe serves as the system integrator with overall responsibility for the generator, supercaps, power electronics and energy management. Ventura Systems Inward Swinging door and Outward Swinging door are the standard doors for the Citea. The four cylinder EEV diesel engine is built by Cummins. The rear axle, developed by ZF, includes two electric motors, which are integrated into the axle. Though there is some additional weight due to the supercaps, batteries and electric driveline components, VDL has been able to restrict it to an absolute minimum.
