Mercedes-Benz Hits Milestone on Mission to Create a Cleaner Earth

The countdown to zero emission buses has started

The countdown to zero emission buses has started: towards the end of next year, Mercedes-Benz will be starting series production of a city bus with all-electric drive system based on the international best-seller, the Mercedes-Benz Citaro.

“Our city bus produces zero local emissions and is ultra-quiet through town. The engineers are currently undertaking thorough testing of prototypes of the new bus under the toughest of conditions. As the technical concept, which involves a modular system for the power supply as well as optimised thermal management, makes clear: the Citaro with battery-electric drive will set a new milestone”, says Hartmut Schick, Head of Daimler Buses.

Der Citaro mit vollelektrischem Antrieb durchläuft zurzeit den gleichen umfangreichen Test- und Erprobungszyklus wie jeder andere Omnibus von Mercedes-Benz. Prototypen haben zum Beispiel erfolgreich eine erste Wintererprobung bei eisigen Temperaturen am Polarkreis und eine Sommererprobung in der Hitze der spanischen Sierra Nevada absolviert.
The Citaro with all-electric drive is currently being put through the same comprehensive cycle of trials and testing to which every other bus built by Mercedes-Benz is subjected. Prototypes have, for example, already successfully undergone initial winter testing in icy temperatures at the Arctic circle as well as summer testing in the heat of Spain’s Sierra Nevada.

Modular design of battery packs allows range to be tailored

Mercedes-Benz celebrated production of the 50 000th Citaro just recently – but development of the world’s number one best-selling city bus continues apace. Hot on the heels of the recently introduced Citaro hybrid with its highly efficient diesel or gas-engine drive system comes the next step, the all-electric Citaro.

It receives its drive energy from lithium-ion batteries. The modular design of the battery pack means that individually customised solutions can be devised to match a wide range of applications and requirements in city traffic.

As well as the possibility of charging it from a power socket at the depot, Mercedes-Benz can also as an option supply the Citaro with one of a range of intermediate recharging solutions. The vehicle is powered by electric wheel hub motors at the rear axle, a system already proven over recent years in the Citaro G BlueTec Hybrid.

Thermal management reduces energy consumption dramatically

One of the particular features of the Citaro with all-electric drive will be the meticulously refined thermal management of the bus’s drive and climate control systems. This thermal management reduces energy consumption significantly and is tantamount to extending the range of the bus without changing the size of battery.

Successful testing in bitter cold as well as extreme heat

The Citaro with all-electric drive is currently being put through the same comprehensive cycle of trials and testing to which every other bus built by Mercedes-Benz is subjected. Prototypes have, for example, already successfully undergone initial winter testing in icy temperatures at the Arctic circle as well as summer testing in the heat of Spain’s Sierra Nevada. Endurance testing and detailed refinements will now follow, ensuring that Mercedes-Benz will be able to offer maximum availability on a par with that of a conventionally powered urban bus.

The Citaro with all-electric drive will celebrate its world premiere in September 2018 at the IAA Commercial Vehicles show in Hanover.
