It emits zero local emissions and runs almost silently. It combines the thousandfold proven platform of the world’s best-selling city bus with new technological solutions. The all-electric Mercedes-Benz eCitaro takes electric mobility using city buses to a new level altogether. The new eCitaro offers an impressive and unprecedented standard in energy efficiency, courtesy of its innovative thermal management system that uses innovative components available for the first time with the launch of the eCitaro. Its performance enables the eCitaro to cover a large part of the requirements of the transport operators right from the start. In addition, it is ready for the battery technology of the near future – the performance capabilities will increase quickly. At the same time, due to the high development effort and extensive testing, it comes to the starting line already fully matured. In addition, the intelligent modular concept of battery and charging technology is compelling. Its design fuses the basic shape of the Citaro with elements of the Mercedes‑Benz Future Bus into a distinct appearance. It is also more than just a city bus: Mercedes-Benz takes a holistic view of electric mobility, embedding the eCitaro firmly in its overall eMobility system. In addition, the eCitaro is the starting signal on the road to an electric future.

The platform of the new Mercedes‑Benz eCitaro is the Citaro, the world’s best-selling city bus with more than 50,000 units sold. With its wide range of low-emission and now also locally emission-free city buses, it has the right answers to questions about environmentally friendly local public transport.

The Citaro and the large-capacity CapaCity bus, as well as the Citaro hybrid and the Citaro NGT, provide practical evidence of the highly sophisticated level of development of powertrains with combustion engines every day. They are characterised by both their efficiency of operation and their low emissions. The all-electric eCitaro is now taking the next step from low-emission bus to locally emission-free bus.

The powertrain of the new eCitaro is based on the proven and optimised electric portal axle ZF AVE 130 with electric motors at the wheel hubs. The peak output of the motors is 2 x 125 kW, while torque is 2 x 485 Nm. It is an inherent feature of such motors that this is fully available right from the start, ensuring appropriate dynamic performance even with a full complement of passengers.

Lithium-ion batteries with a total capacity of up to about 243 kWh provide the power. They are modular in design: the batteries are split between up to ten modules, each supplying around 25 kWh. As well as two battery modules on the vehicle roof, the standard equipment includes four modules in the rear of the bus. In the eCitaro, these are taking the place of today’s powertrain combination of combustion engine and transmission. Depending upon customer requirements, another two or four battery modules are mounted on the roof of the eCitaro.

Each battery module is made up of 15 cell modules as well as a control unit for monitoring purposes and as a means of balancing the charge of the battery cells. Each separate cell module houses twelve battery cells. Mercedes-Benz uses easily manageable prismatic cells with a capacity of 37 Ah each. With a minimum of six and up to a maximum of ten possible battery modules, transport operators can adapt their usage and charging strategy very precisely to individual needs. Opting for the largest number maximises the range of the buses, while a smaller number reduces the weight as well as the cost of purchase and allows more space for passengers – but potentially makes time-consuming opportunity charging necessary.

With the maximum complement of ten battery modules, the eCitaro in standard specification weighs around 13.44 tonnes. In conjunction with a gross vehicle weight rating of 19.5 tonnes, this corresponds to a payload of more than six tonnes or around 88 passengers – in line with what is needed in practice even during rush hour.

The passenger compartment of the eCitaro is heated in an energy-efficient manner by a heat pump. An even temperature distribution is ensured by use of the familiar sidewall fan heaters. The conventional heater at the front is boosted by the addition of a double heat exchanger. For selective use in extreme weather conditions in the range of minus ten degrees Celsius and below or to extend the vehicle’s range, a fuel-powered auxiliary heater can optionally be used.
