Mercedes-Benz has announced the world premiere of its all new eCitaro electric city bus.
According to the German automaker, the eCitaro looks familiar to the Citaro city bus, but takes up elements from the design idiom of the revolutionary Mercedes‑Benz Future Bus concept vehicle.
The first Mercedes-Benz eCitaro will be delivered at the end of the year and will go into practical operations in the context of a so-called customer-oriented driving test.
Daimler Buses will invest around $233 million in the implementation of its CASE strategy which stands for the future topics of connectivity (Connected), autonomous driving (Autonomous), flexible use (Shared & Services) and electric powertrains (Electric).
The eCitaro is powered by lithium-ion batteries with a total capacity of up to about 243 kWh. They are modular in design with the batteries divided between as many as ten modules, each supplying around 25 kWh.
In addition to two battery modules on the vehicle roof, the standard equipment includes four battery modules in the rear of the bus.
With the maximum complement of ten battery modules, the eCitaro in standard specification weighs around 13.44 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.
According to Daimler, battery capacity alone isn’t sufficient to understand the actual performance capability of an all-electric city bus.
Daimler has therefore put a considerable amount of thought into the issue of thermal management: Compared with the current Citaro with combustion engine, the energy requirement for heating, ventilation and climate control has fallen by about 40 percent.
Though the eCitaro can drive around 250 kilometers without opportunity charging, Daimler is planning to further extend the travel distance of the eCitaro by a range extender in the form of a fuel cell that generates electricity.
