Scania doesn't have 12.8m / 13m chassis in its portfolio. But
chassis extension by Gemilang is possible . But scania k310UA are
really bumpy ( sit in the rear upper level )
Volvo B8L hasn't been proven yet on our island yet.
Enviro 500 mmc 12.8m is common in HK streets with quite
successful operations
MAN has quite alot of experience in 3 doors 12.8 /13m buses in
Europe & is the main supplier of the 3 door trial unit so this
give them quite the advantage in tender.
Did you mean KUD? KUA is bendy.
