2023-09 SUSTAINABLE BUS
A new issue of Sustainable Bus is out today. In this upcoming edition, we’ve curated a diverse and comprehensive range of topics that spotlight the latest developments in the world of sustainable mobility. From cutting-edge technological advancements to market insights and industry transformations, this issue promises to be a captivating exploration of the future of public transportation. What you could fine inside? Well, a market insight will offer you a detailed look at the European e-bus market, providing you with a comprehensive understanding of the mid-2023 results. The leading e-bus market in Europe is still UK: therefore, we focused our attention on that specific market with a report that sums up strategies, focus, goals of the most prominent industry players. A technology spotlight on the delicate topic of batteries, authored by Claudius Jehle, look at battery management and strategies to ensure the smooth and cost-effective operation of electric buses (with a focus on a case study from BVG). Among the pillars of our upcoming issue you’ll find a detailed journey around the European industrial bus&coach landscape. Goal? Providing our readers insights into the changing dynamics among key OEMs in the region. We’ll be then taking you behind the scenes at the Yutong factory in Zhengzhou, that we had the pleasure of visiting in June. Let’s then delve into Iveco Bus’s growing efforts in the zero-emission bus field. Finally, last but not least, a nearly-20-pages comparison between seven 12-meter battery-electric buses, gathered together in Bonn also this year by the German magazine Omnibusspiegel. You’ll find both established players and newcomers side by side: Ebusco 3.0, Hess lighTram 12m, Ikarus 120e, Iveco E-Way, Mercedes eCitaro with new batteries, Otokar e-Kent C, Quantron Cizaris 12 Ev.

COMPARISON<br />
tunity to see recently launched models<br />
(e.g. Ebusco 3.0, which was offered to<br />
the press outside a trade fair pavilion for<br />
the first time) or models waiting for their<br />
first significant orders (this is the case of<br />
Otokar and Quantron). Hess and Ikarus<br />
complete the list. These two manufacturers<br />
have an eminently local penetration:<br />
Swiss for the first, Eastern European<br />
(with an eye on central Europe) for the<br />
second.<br />
In mid-April, we once again flew to Bonn,<br />
Germany, where the Omnibusspiegel<br />
magazine has been organizing the Ebus<br />
Test for years. A journalistic initiative<br />
that aims to bring together a large representation<br />
of electric buses available on<br />
the market, committing them to a week<br />
of tests and assessments.<br />
The vehicles are subjected to rigorous<br />
technical analyzes and assessments of<br />
their behaviour, both in static conditions<br />
at the depot and in service simulations<br />
on a specially created street circuit. This<br />
initiative is made possible thanks to the<br />
support of Bonn SWB’s municipal public<br />
transport company, which makes<br />
the depot (and the charging infrastructures)<br />
available.<br />
Had Solaris and VDL also been present,<br />
as they often participated in past editions,<br />
we would have had in front of us<br />
the representatives of almost 40 percent<br />
of European electric bus registrations<br />
2022. The e-bus market is extremely<br />
fragmented and difficult to embrace<br />
from an overall perspective. A simple<br />
comparison: looking at the overall European<br />
bus&coach market over 8 tonnes,<br />
five manufacturers account for 70 percent<br />
of all registered vehicles. To reach<br />
the same percentage in the e-bus arena,<br />
eight manufacturers are needed.<br />
