I do the same as x43x, 70 degrees and sunny outside I ensure the hvac is on, recirc is off, the temps turned down and the AC off. Opening a back window give more air flow, but is noisy. The air flow outflow vents are out of a rubber covered vent in the drivers side, back corner of the car. You can see it if the rear bumper cover is off. This also brings up a surprise that occurred after I got my I-Pace home. Every 2 bit electric car for sale in the US since 2011 had electric seat heaters as standard equipment. My Ford Focus Electric had them and on most days, they were all you needed to keep your self warm. They used <1 kilowatt. I was shocked to see that seat heaters were an extra cost item on the I-Pace. So I made sure I got an I-Pace with the expensive seat heaters. I had a nasty surprise reading the owners manual, when I got the car home. The seat heaters are not electric wires in the seats, they are heated by the heat from the heater water tank and the manual says they are very inefficient. It appears that the Jag engineers never looked at or drove any other electric cars before designing their seat heaters.
