Does anyone have insight into how the rear AC unit is setup in the R53? Curious if it impacts MPG when in use. For example, if the front unit is running, does MPG dip even further with the rear unit ON too or is it all the same system?

It could cause the a/c compressor to cycle more given it's got to send refrigerant to the rear evaporator coil.

The compressor cycles with any of the HVAC settings anyway, so any fuel economy impact is going to be minimal.
