My wife and I just made a roughly 1,100 mile trip from Massachusetts down to DC then back with a couple of stops in Pennsylvania. Mostly highway but some great PA back roads as well. I purchased a Modern Spare before the trip as an offering to the tire gods and set off with a straight 9.5 hour run on the first day. I normally use only Pure and Polestar modes but for this trip I used Hybrid mode with battery hold for all of the highway driving. That gave me 32 to 33 MPG excluding any of the pure battery miles (essentially running it as a mild hybrid) and it performed beautifully. I set the dampers on comfort (12F:15R) and the ride quality and handling was also outstanding. We’ve made this trip several times in our XC40 R Design and there’s no comparison. 9 hours straight in these seats was a non-issue.
I also fully committed to using one pedal driving throughout the entire trip and I’m totally sold now that I’m used to it. Man, I love this thing.
