Foton View 15 seat passenger van vs. Foton view Ambulance that is.



From the outside they are different in:
*Front fascia
*Different body graphics/sticker design
Inside:
*More modern dashboard on the passenger van
*Lockable center console on passenger van
*Rear a/c up to last row on passenger van (ambulance model only has them on the b-pillar like the old Nissan Urvan)

QUESTION: I know they share the same name but what are the other differences between the two models?
*Are the engines the same? From what engines are the Foton engines 'copied' from?
*Are the wheelbases different? The height is obviously different (ambulance has standing room)
*Do the units come with a tachometer?
*How is the durability/reliability of this model?

Thank you.
