Echoing SeattleCat re. HeatPump -- its an integrated mechanics on the overall design. Nothing for Drivers to engage with -- "assuming" it's working, it's supposed to recycle the heating/cooling portion back into the system resulting in "saved energy" - what does that equate to ? Perhaps a few extra miles.P8 owner for one month. Life long Volvo owner (50 years)! Awesome addition to my Volvo experience. However..... 1) being told that VOC, Google automotive, Sirius XM, and Apple Car Play are waiting software updates that may be not until late summer or the fall is unacceptable. IT IS SOFTWARE! How can that require months to resolve and distribute? 2) our delivery options were fixed at the time of order, being told that other than the color and tire size all vehicles distributed in the US (Northeast) would have a heat pump, HK audio, heated front/rear seats, etc. No complaint there, all great to have. However there is no instruction on the heat pump operation in the owner's manual or provided by the dealer at delivery. How does it work in hot weather vs. cold weather, is there any action needed in its use or non-use??? I look forward to the software updates and bug (of which there are many) resolutions! Other than that, the P8 is our retirement adventure to enjoy.
