Welcome Bro
Well, you are right - imo its certainly not an apple to apple comparison, I happen to think that for Proton including Japanese makes - they have better air conditioning prowess ! Relative to my all my previous vehicles all Japs - their air conditioning is great - quick to cool and quite silent. My F30, aiyo, takes relatively longer to cool - and when full blast - bunyi macam ade tornado !
Besides, MPV & sedan aircon outflow rates different i think - more evenly distributed between front and rear sections for MPV.
