    Just took delivery of a 6-seater 2 weeks ago, it has front and rear AC.

    I have both a five (2016) and six seater (2018) X and the six seater is considerably cooler in the rear.

    That's just rubbish, I often sit in the back of our 6 seater with my daughter when charging/stopped for a break on a road trip.

    The difference in temp/cabin feel in the back with the rear aircon/fan on/off is massive in both winter and summer. Operation of the rear fans is 100% independent of the front, you have the rear on full blast and the front fans off at the same time.

    So I did some searching on the Parts Catalog because I was curious and didn't really want to rip apart my Model X.

    Looks like there is only one A/C compressor no matter if you have rear A/C or not. There is, however, a different part number for the compressor. It looks like the compressor is larger if you have rear A/C judging by EBay pictures.

    We can also see there is indeed a front (left side) and rear (right side) assembly with independant fans and heaters.

    And here we can see the HVAC lines. I can't find the rear evaporator, but seeing as we're running R134A high and low pressure lines to the back (Rocker to Rear HVAC is the name of that part 7) there's certainly an evaporator back there somewhere that we're using to cool.

    So yeah long story short, 6 and 7 seater Model X do indeed have a mostly separate front and rear A/C system with the only real shared part being the compressor. The compressor appears to be larger (or at very least different) for models with rear A/C.

    I'm not sure what the difference between the -00- and -99- parts are however.

    Some of the explanations I see posted are like saying there are no dual motor cars because there is only one battery.

    Front and rear HVAC work the same. One central compressor with dual air handlers. Each air handler has independent control, an evaporator coil, fan, ducting and heat elements.

    So back to my current question.

    Do current production five seat, flat fold, Model X cars now ship with the front and rear AC system?

    The order page no longer has a footnote on the six and seven seat configuration indicating a dual system is included with that seating arrangement.

    i have a december 2017 X 5 seater. today it was 98F sunny so i tested the rear AC while supercharging for an hour.

    it was perfectly acceptable and even got a little chilly when i pushed it down to 65F while sitting in the rear seats. the airflow from the center armrest console is much stronger than the side vents on the door frames but they do still put out some air. easier to feel above fan setting 6. the rear cargo hatch was still much warmer even with the microdot sunshade installed as there are no working vents back there and constant sunlight heat from the glass hatch. i would guess 85F.

    make sure the vent slots are in the open position. during daytime it is easy to see but at night you can't and people can mistakenly close them trying to angle them since the 1 control does the angle as well as complete closure.

    So is there now a C pillar vent for the raven 5 seaters? This should be an easy thing to determine. I would rather not have to pay for an unneeded 3rd row just to get adequate AC coverage.

    Answering my own question:
    I checked out the 5 seater raven in person today, and the answer is no, there are still no vents for the 3rd row.
    This is a bit of a deal breaker for my dog with long trips.

    Thank you for getting back to us on this. I imagine this will change a lot of minds about the 5 seater and the cooling!
