The eCitaro already starts well-honed. Its top quality is ensured by the Citaro that is already proven many times over. Add to this the production in the plant in Mannheim on the line of the conventionally driven Citaro – this already applies to the trial vehicles. Significant components, such as the drive axle or the electrohydraulic steering, are already proving themselves in the strenuous city bus service. The roof structure with integral heavy load rails for the batteries goes back to the Citaro NGT and its gas tank.
Furthermore, the eCitaro has completed comprehensive testing before its series launch. The bus had to pass the same test as every other bus with a star, as the eCitaro will attain the same high availability as its virtually proverbial reliable colleagues with a combustion engine.
All components were inspected, both individually and in interaction, at test stands and in practice in the bus. Mercedes-Benz has tested the eCitaro at temperatures of below minus 15 degrees Celsius in the polar circle and at more than 30 degrees Celsius in Spain's summer heat. The winter tests also included road tests on a slippery road to check driving dynamics regulation systems and recuperation. The bus completed summer tests in strenuous urban traffic and on steep ascents and descents in Sierra Nevada. The test programme also included rough road and endurance tests. Overall, around a dozen prototypes were put through their paces. This effort costs time, but does lead to a high level of development at the market launch of the eCitaro.
