Took SMB1584K on 187 Today Evening. BC was really flooring the
accelerator at every move off. I would say A22 fitted with Voith
gearbox can pick up speed faster and maybe better for flooring. It
sounds quite abit like the O405G 12XX series
The drivers have to kick down almost every time they move off
because the accleration is simply not as good as ZF. I would expect
the fuel consumption of the Voiths to be higher as such.
If you have taken a ZF being floored, you would know how much
faster it goes, but most of the time drivers don't need to do so as
the bus is able to give a reasonable accleration for them.
