London celebrates premiere

10/18 Only early risers could experience the unique spectacle in front of the impressive backdrop of Westminster Abbey on 11 October, when the first 100% all-electric sightseeing bus equipped with the gearless wheel hub drive ZAwheel® from Kupferzell was presented. In the presence of London’s Deputy Mayor for Environment and Energy, Shirley Rodrigues, press representatives and guests, the bus of the future launched its first tour. With this first step towards zero-emission bus travel in the London capital, the responsible politicians have taken courageous measures to drastically reduce air pollution. The ZAwheel® electric wheel hub drive developed by ZIEHL-ABEGG, which guarantees quiet and clean driving through the streets, plays a decisive role in this project. Mayor Shirley Rodrigues congratulated Ronan Bois, also in attendance, who was in charge of sightseeing at RATP Dev, operator and subsidiary of the international RATP group of The Original Tour – Hop-On-Hop-Off-Bus. The bus is built by the Spanish company Unvi, which is regarded as the world’s largest manufacturer of city sightseeing buses. Together with strong European partners, including ZIEHL-ABEGG, this great success was achieved in London. The start of the energy revolution in London has thus been made, even six months before the introduction of the Ultra-Low Emission Zone in central London. Further buses are to be deployed in 2019.
