We finally got enough snow here where I was able test out the Solterra on snow tires (Blizzaks). It still did swerve and slide around a tight corner, but the ABS did an admirable job of keeping the skidding reasonable, and I was able to regain control within a couple of seconds. Anecdotally, it did seem more stable than either our former Crosstrek or Forester, probably due to its weight… though this is hardly a scientific test.
As far as AWD goes, we take it offroading all the time (but not like dune crawling or rock hopping, just what we in the US call forest service roads… mostly dirt, gravel, and sometimes mud). It handles really quite well in those environments, like any other Subaru I’ve been in, just with much improved acceleration (low-end torque). The BEV-ness of it actually makes navigating ditches and potholes and such a lot easier; it’s so much easier to get back to speed immediately after slowing down for a bigger dip, and the regen limits brake wear from all the starts-and-stops of such driving.
I haven’t and probably won’t take it into deep snow, mostly because recovery would be a huge PITA. Besides, any generic car with good tires and studs or chains (and of course driver skill) would do better than AWD in the snow & ice anyway.
The Subaru BEVs are still some of the cheapest non-Tesla AWD BEVs out there, both current and upcoming models (even compared to their Toyota sister cars, for some reason, at least in the US). My '25 Solterra was about $36k USD for the second-highest trim (Limited).
But that said, you saw my complaints about the app and cabin features in the other thread, I hope. They’re minor-ish, but good to know.
