I bought the AWD, the price was about the same so why not. The rear only has 7hp but 40Nm if I remember correct. I was skeptic but again not that much of I price difference so I went for it. According to the manual the rear electric motor can help you if you get in to a skid. I have not got stuck or had a bad skid or something like that, I cant tell though if that is because of the AWD. I use to tow my snowmobile with a GS300 from 2000, all my cars has winter tires but all have had stud less tires. The UX has Continental viking contact 7. The UX has this winter towed my snowmobile on the same road and same conditions as my GS did. The road to where I snowmobile is really bad, it twist goes up/down constantly and no salt. I feel that the UX feels much safer to drive on snow/ice then the GS300 but I dont know if that is because the GS is very old with many miles or because of the UX AWD. Hope this helps.
Yes, towbar is allowed on the UX here in Sweden, factory option but no big heavy trailers...
