Recently back from our first long road trip in the Expedition (2026 KR XL), and continue to be impressed with this vehicle.
We drove from the Carolinas to the NE tip of Maine, with stops in Baltimore, Salem, Portland, Mt Desert Island, Newport, and NYC along the way. Primarily interstate between Carolinas and Massachusetts (both ways) and primarily small highways/back roads while in MA, NH, and ME (plus city driving).
The vehicle fuel consumption/mpg monitor proved remarkably accurate (much moreso than in previous vehicles I've owned or still own). Trip meters calculated 20.4mpg over 2,700 miles, and both the total and interim trip meters run for each fill-up were within 1-2 tenths of an mpg with calculated mpg (I use an app to track fuel and other vehicle expenses over time). Interstate speed were between 70 and 80 mph, calculated speed for the entire trip was a little over 40mph - so a fair amount of time in traffic/at lower speeds or stops going through towns and villages (as well as heavy traffic in and around NYC). Regular gas the whole way, and plenty of power/acceleration when needed even without the higher output engine option. Overall, I'm pleased (even a little surprised) with this fuel mileage - with the big XL fuel tank this means I could get close to 600 miles on a tank... more than enough for me.
Comfort was fantastic, both for me and my passenger (and pup in her kennel in the rear). I only did 1 "long haul" 9 hour stretch this trip, but was never uncomfortable nor restless, and not too tired at the end of it. Most days were 4-6 hours in the vehicle, which was a breeze. I also think the exceptional noise control in these vehicles, between the double-laminated glass, CCD, and noise cancellation, contributes tremendously to comfort and lack of fatigue.
The square wheel is exceptionally comfortable for interstate cruising. I made use of BlueCruise a few times (primarily to eat a burger on the road - my other half hates when I drive with me knees) and have to say I was extremely impressed... though I prefer driving myself and only used it when I had a particular need for it. The adaptive cruise works well when set to the shortest gap.
I didn't have any opportunities for true off-road testing, but had plenty of tight spaces to navigate (parking and otherwise) and found the Expedition very easy to handle in such places. Even NYC wasn't awful (actually, a big vehicle may be helpful as the idiots can see you and actually pay attention to you). Again, the square wheel was quickly forgotten as a concern.
For traveling with a dog, the split rear tailgate is truly ideal - it provides just enough clear space to feed the dog or just to sit with dog while taking a break or enjoying scenery - and means you don't have to move any of the stuff you have packed.
I was disappointed that the cargo area only offers 2 tie-downs - I like to have my kennel secured for my pups safety. The work-around I found, since I had the 3rd row folded down, was to secure the forward end with a small strap attached to the non-removeable 3rd row headrest (in its down position).
I still think 18" wheels would be better, and will likely put some on when tires need replacing, but otherwise extremely happy with this vehicle.
