Citaro a cannot manage heavy loads. But the cherry on the icing
is the bigger order of DDs. Hence, if Citaros are doing the
off-peak direction of a service, should be okay.
The Citaro is as good (or as bad) as the operator's
specifications. Mercedes-Benz/Evobus simply deliver what is
ordered. The base Euro V engine combined with the standard
4-speed automatic gearbox is adequate for low-speed urban duties on
a flat topography but more demanding applications require a
stronger powertrain or driveline and these are most certainly
available as optional extras.
