With three newly delivered Mercedes-Benz eCitaro electric buses the German cities Mannheim and Heidelberg have a complete electric bus line service.

The first purely electric eCitaro bus service in Heidelberg goes from the main train station via the Seegarten to the Karlsplatz and then later to the Altstadt commuter rail station. Bus route 20 travels through Heidelberg's city centre every 20 minutes, whereby it is expected that in the future two vehicles will cover the four kilometre long route with 12 stops. One of Mannheim's electric bus routes leaves from Käfertal train station and travels via Wasserwerkstraße to the Franklin district, a new district where members of the US armed forces used to live. The other route begins at the Platz der Freundschaft and ends at the new Taylor industrial estate, which also once belonged to the US armed forces. One eCitaro will be in operation on each route.

In Heidelberg, were Till Oberwörder, Head of Daimler Buses, handed over the vehicles to Martin in der Beek, Technical Managing Director at rnv, and Mayor Eckart Würzner of Heidelberg, the vehicles will be on the road between 9.00 a.m. and 10.00 p.m. and in Mannheim between 6.00 a.m. and midnight. This corresponds to a daily mileage of about 200 kilometres or more per vehicle provided by lithium-ion batteries with a total capacity of 243 kWh. The battery design is modular, comprising 10 modules each with an output of 25 kWh. In addition to the six battery modules on the vehicle's roof, four battery modules are the rear of the bus. The buses are charged using a combi-2 plug. The target is a mileage of 200 km or more for each vehicle which can be achieved with fast charging in the form of top-up charging during breaks in operation. The newly developed charging device has an output of up to 150 kW and is to be delivered to rnv together with the eCitaro.
