Even before the premier at the IAA, Mercedes-Benz managed to sell 20 Citaro Electric buses to long-time customer Hamburger Hochbahn from Hamburg. The first two will be delivered by the end of this year.

It could be just begining as Hamburger services 111 routes and 1,327 bus-stops with around 1,000 buses. By 2020, the company intends to procure emission-free buses only.

Till Oberwörder, Head of Daimler Buses:

"The first major order for our fully electrically powered, emission-free Citaro has been received even before the official premiere, demonstrating the confidence transport operators have in our concept for electromobility in urban public transport. With the Citaro, we are bringing a major component on the way to locally emission-free bus traffic to market."
