the difference in unladen weights could be down to the
difference in weight for the individual metal components and
related components used to build up the chassis. They typically
differ from bus-to-bus, but seems like in this case, those that
have the similar unladen weights would hint that they're built
around the same time in MB's factory using the same components from
a shipment.
typically it's normal to see up to +/- 50kg for chassis unladen
weights from what I observed from buses registered here, especially
the buses from 1990s. There's some VO3xs that have unladen weights
that differ up to 70kg.
But the difference in VIN numbers for the Citaros is a different
thing in itself.
thanks for the clarification.
another reason why there is weight variation (in the range of +
or -50kg) for newer buses may lie in the amount of diesel and/or
adblue in the vehicles when they are weighed and registered. as
mentioned, a 50kg diference is not significant enough to disclaim
major mechanical or even electrical differences across vehicles of
the same model.
to also make an extra note, mechanical components built to spec
should not have too much variation in weight, and id think weigh
the same. i can agree that the weight variation may be due to
components from the same batch used in the same buses, although im
indulging in the idea that a 50kg in mechanical component weight
may be a tad much :P
there are 3 versions of the VIN in use worldwide (ISO, EC, JIS)
and all 3 versions are
internationally accepted. the change in the Citaro VIN is
more likely to suggest a different production batch (within Evobus) that may still
be part of the same
Purchase Order placed by SBST.
