I’m frequently of when Albuquerque tried to switch to electric busses several years ago now.
The city ordered a bunch from BYD. The first testing units failed miserably. They wouldn’t last a whole shift, doors wouldn’t open, or open when they shouldn’t (while moving), there were a number of problems. After a month or so of testing and trying to work with BYD, they gave up on the order and went with some kind of ethanol busses instead.
That was a bunch of years ago now. I wonder if they’re any better.
Buses probably have its chassis and body built separately.
For example the BYD K9 in Singapore has a chassis from BYD while the bodywork is from Gemilang.
AFAIK most city public transport buses are built the same way as the public transport operator requires a specific configuration of seats, doors, etc to meet regulations.
