Mercedes-Benz Citaro to begin series production late next year
Toward the end of next year, Mercedes-Benz says it will begin series production of a city bus with all-electric drive system based on 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 optimized thermal management, makes clear: the Citaro with battery-electric drive will set a new milestone," said Hartmut Schick, Head of Daimler Buses.
The Citaro receives its drive energy from lithium-ion batteries. The company says that the modular design of the battery pack means that individually customized solutions can be devised to match a 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 used in the Citaro G BlueTec Hybrid.
A key feature of the Citaro is thermal management of the bus's drive and climate control systems. This thermal management is designed to significantly reduce energy consumption and extend the range of the bus without changing the size of battery.
The Citaro with all-electric drive is currently being tested. Daimler says that prototypes have successfully undergone initial winter testing in the Arctic Circle as well as summer testing in Spain's Sierra Nevada. Endurance testing and detailed refinements will follow.
The company plans to start production of a fully viable series-production urban bus next fall. The brand is currently tendering for contracts. The Citaro with all-electric drive will celebrate its world premiere in September 2018 at the IAA Commercial Vehicles show in Hanover.
