It isn’t 4WD, none of the Elroq or Enyaq range ever have been.
The X and vRS have All Wheel Drive (not the same as proper 4×4).
Since version 4.0 and upward firmware versions came out in Dec 2023 that is now only available for traction control at speeds under 20Kph (about 12.4Mph).
I’ve had my 85X out in the snow, I can say it handled a lot better than my previous Seat Ateca which was truly awful, mainly down to the appaling Bridgestone 19″ tyres, I have Bridgestones on the Enyaq (20″) and so far these are a lot better than the previous versions.
Please excuse spelling/typos. Apart from being a clot it turns out I had one on my cerebellum that's now causing various problems!
