Mercedes-Benz is in the final phase of development
of its first all-electric Citaro bus, which will enter series production later
this year. The all-electric Mercedes-Benz Citaro takes electric mobility using
city buses to a new level altogether. The 12-metre variant will celebrate its
world premiere in September at the IAA Commercial Vehicles, with the start of
series production coming before the end of the year. The new Citaro offers an
impressive and hitherto unknown standard of energy efficiency, courtesy of its
innovative thermal management system.
The intelligent modular concept for its battery and
charging technology is a similarly compelling proposition. The electric Citaro
is also more than simply a city bus: Mercedes-Benz takes a holistic view of electric
mobility, embedding the Citaro firmly within its overall eMobility system. This
comprises services that range from individual and very practically oriented
advice ahead of any purchase and recommendations relating to charging
infrastructure through to taking on servicing work at the customer’s own
workshop.
The Citaro and the large-capacity CapaCity bus, as
well as the Citaro hybrid and the Citaro NGT, provide practical evidence,
thousands of time every day, of the highly sophisticated level of development
of drive systems with combustion engines. They are characterised by both their
efficiency of operation and their low emissions. The all-electric Citaro is now
taking the next step from low-emission bus to locally emission-free bus. In
doing so, it adds to the range a variant that sets new standards in terms of
electric mobility.
The drive system of the new all-electric Citaro is
based on the tried and tested ZF AVE 130 electric portal axle with electric
motors at the wheel hubs, as previously deployed in other variants of the
Citaro. Their peak output of the motors is 2 x 125 kW, while torque is 2 x 485
Nm. It is an inherent feature of such motors that this is fully available right
from the start, so ensuring appropriate dynamic performance even with a full
complement of passengers.The German manufacturer promises to show the
production version in September, as first customers are already awaiting
deliveries.
With the maximum complement of ten battery modules,
the all-electric Citaro with standard equipment weighs around 13.7 tonnes. In
conjunction with a permissible gross vehicle weight of 19.5 tonnes, this
corresponds to a payload of 5.8 tonnes or around 80 passengers – even in the
rush hour, as is commonly necessary.
With a strengthened offer from Volvo and new players
entering market like Scania, Mercedes-Benz joins the party just before it’s too
late. What is more, by the time of the series-production start-up, the
all-electric Citaro will already have been through a comprehensive programme of
testing. This bus has to pass all the same tests as any other bus that bears
the three-pointed star, for the Citaro with all-electric drive system will
offer the same high level of availability and the proverbial reliability of its
stablemates with combustion engine.
