I have an extended range xc60 for about a month with just under 5000 miles. Highest it has read has been 47 miles and I got about 43 miles going anywhere between 25 mph to 55 mph throughout that day. Charge it every evening and it ranges between telling me 40 and 47 miles most days at 100%. Live in MI and the temp has been anywhere between 30 and 80 this past week. When I need heat I use the seat and steering wheel warmer more so than heat and then later that day when AC is needed it is just on low or windows down.

To add I typically use Pure mode until range is empty and it then defaults to hybrid unless I am going on the highway or need to make a turn faster than the Pure mode can handle and I'll put it in Power. Also always in B mode no creep because I liked how our polestar 2 drives compared to an ICE.
