Daimler Truck has achieved a significant milestone by producing and delivering more than 2,500 eCitaro electric buses in Mannheim since the commencement of series production at the end of 2018. These buses have been supplied to various European countries, including Germany, France, Italy, Sweden, Austria, Switzerland, and Poland. The eCitaro range, which builds upon the Citaro city bus platform, offers different configurations with varying battery capacities and door options to cater to different transportation needs. The latest models feature NMC3 lithium-ion batteries, with the capacity reaching up to 588 kWh for the solo version and 686 kWh for the articulated model. The innovative thermal management system in the eCitaro significantly reduces energy consumption for heating, ventilation, and air conditioning compared to traditional combustion engine buses. Furthermore, Mercedes has introduced a hydrogen-powered version of the eCitaro, utilizing a 60 kW fuel cell as a range extender alongside high-voltage batteries. An upcoming 'H2 mode' will enable the bus to operate solely on hydrogen, eliminating the need for stationary recharging. Future developments include transitioning to NMC4 battery technology in 2026, enhancing capacity, range, and longevity. Mirko Sgodda of Daimler Buses emphasizes the continuous improvement and success of the eCitaro, highlighting its attractiveness, safety, reliability, and operational efficiency.
