Efficiency isn't going to help if you don't have the range to get where you are going. Then the grippier tires the UX might need will likely reduce its efficiency. Now, 150+ miles is plenty for daily use, but it likely means many will need to install a Level 2 EVSE. I would with my 60 mile round trip commute. While over 200 miles can put off getting the faster EVSE, even if Level 1 doesn't fully replenish a days use overnight. Not familiar with working in pounds, but the price difference seems fair. You are getting AWD, better performance, and longer range with the Volvo's higher price. It starts at $55,300 with 208 mile EPA range in the US. I might find the seats alone worth the extra cost.
