The Citaro hybrid was specially developed for the demands of regular-service bus routes in urban conurbations and stands for contemporary mobility with reduced consumption. The economical diesel or gas engine is assisted by the additional drive power of a highly efficient, compact hybrid module. The 14 kW electric motor generates energy when coasting and braking. It therefore assists the diesel or gas engine when pulling away. Depending on use, this can reduce the fuel consumption by up to 8.5 percent.
