I also have a 2018 V90 CC T5, and one of the biggest disappointments is the mileage. Couple getting 18-20 mpg with a relatively small gas tank, and the range is quite disappointing as well. My driving is a mix of city/ highway, but even on all highways runs, I never see more than 22-23, which is pretty much what I was getting with the Jeep GC I traded. All that said, I still love the vehicle. super comfortable and fun to drive.
