Hot air
According to SA, & it seems reasonable upon inspection under hood,
all vent air also comes thru the air intake in frt of the radiator, thru the engine, then into the cabin. So warm engine/ hot day = warm vented air.
i'm amazed they didn't engineer ambient temperature fresh air venting !
It means we've to turn A/C on in hot climate!
What kind of Efficiency Dynamics is that!?
