The electric Citaro is 12-metre built on the customisable city bus platform with a GVW rating of 19.5 tonnes. The key element of this bus is the ZF AVE 130 electric portal axle consisting of twin-electric motors at the wheel hubs. They deliver an output of 2 x 125 kW power and 2 x 485 Nm torque together. Daimler claims that power delivery is consistent right from the start, thereby assuring a dynamic performance especially in start-stop operations.

In standard fitment, two modules are located on the roof, while four others are in the rear compartment. If customers wish for a longer power bank, four more modules can be arranged on the roof. Each module is made up of 15 cell modules, with each cell module consisting of twelve prismatic cells with 37 Ah capacity each.

As far as charging, a standard Combo 2 connector (CCS) is envisaged for the production version. However, to make the charging more flexible, Daimler can extent opportunity charging via a roof-mounted pantograph. As of now, based on Standardised On-Road Test cycle (SORT2), the Citaro Electric with a full complement of batteries achieves an operating range of 150 kms.

Mercedes-Benz Citaro Electric has undergone comprehensive testing and validation, even in cold operational conditions.

Further, energy-efficient thermal management has been the project’s yet another priority. Therefore, cooling and heating requirements for the passenger compartment is achieved in most viable manner. The bus maker can extend every passenger comfort and safety technologies that are already offered in Citaro range of Euro 6 and hybrid buses.
