I'm comparing between my Pajero and CX7. The Pajero's temperature inside gets (driver side, rear aircon of Pajero not turned ON) to a comfortable level at least twice faster than the CX7. Both have the same brand and type of tint (3M). The only difference I can see is the cabin size.

Shouldn't it take the Pajero to cool down a little longer since its aircon needs to cool more volume of air compared to the CX7? Or the Pajero's insulation is just better than the CX7?
