Seems consistent with our experience. Q8 etron does the 1000km same or faster than Model X LR Raven which is the same size (see below from the video you showed, same time for 1000km, though Model X was in warmer weather). From experience, Audi estimated range is vey close to what we get, Tesla was always showing unattainable rated range (I have a decade of driving Model S'es, never once managed to get rated range for the full charge duration, not even in the summer).

That said, if you are looking for a mile muncher, an EV which will get you long distanced the fastest, I'd suggest Lucid Air GT or Audi eTron GT,
Bjorn managed 9:35 in the Audi for 1000km in it in relatively cool weather (couldn't find Bjorn 1000hm challenge with Lucid):

For our household, my wife uses the Q8 etron for daily driving. For long trips we use my Taycan CT, which is the same platform as the eTron GT, and per
Bjorn faster (over 1000km) than any Tesla other than M3 LR 82KWh, which is a significantly smaller car, much less luxurious and much, much, much lesser equipped (no torque vectoring, active chassis leveling/control, air suspension, HUD, night vision, 18 way sport seats to hold you in place during spirited drives, etc).
For a long time Tesla had the edge, no surprise competition is catching up, no longer the fastest, no longer the longest range, no longer the fastest road tripping either. What Tesla still has is most practical utilitarian car for the money, and smoothest OTA updates. I still recommend 3/Y as most practical EV for the money. S/X were rather overpriced, especially since they dropped their interior to 3/Y level, but since the price cuts they are somewhat more attractive, offering a larger vehicle with air-suspension and more power than 3/Y.
