I mean CDGEs and newer those buses. For the WEGs, it's mainly the
loud radiators that cause them to be noisy, not really the engine
unlike for the E500s where the engine is mainly the cause.
If thats the case how many bloody varients of DDs are there to
begin with? This makes it a non-issue since at worst the ADL is
only beaten by 2 variants of buses. Not as loud as you would think
after all is it!
Regarding noise. B9s are really not that much quieter even if we
take away the radiator problem. Sure I admit that ADLs are
generally loud at a stop, but when its moving both are just equally
loud. Just go try it for yourself! The ADLs just SEEM to be louder
since it has a lower pitched noise.
