Among SUV drivers in the US the biggest segment is compact SUVs (think Toyota RAV4 or Honda CR-V). Then midsize (like Toyota Highlander or Hyundai Palisade), subcompact (Mazda CX-30, Hyundai Kona), then full sized (Chevy Tahoe, Ford Expedition).
RAV4 non-hybrid is around 35 mpg highway. CR-V 34 mpg highway.
In midsize, Highlander is 29 mpg highway, and Palisade is 25 mpg highway.
In subcompact CX-30 is 30-33 mpg highway depending on options. Kona is 29-34 mpg highway depending on options.
The full size category, which does get down to around 20 mpg, is only around 3-4% of SUVs in the US. Tahoe is 20 mpg highway. Expedition gets 23 mpg highway.

....35mpg at 60mph and little traffic, maybe. I can't speak for that specific model, but most vehicles I've driven do significantly worse than advertised.
My Subaru Legacy advertised 27 City, 35 Highway, 30 Combined. In practice I average 25-26 while commuting and on extended highways drives more like 29, still on stock tires.
Great, but it's still 9.5 hours of time on the wheel. Train/plane eliminates that. So even if it is 1/3 cheaper in fuel, it's something that needs to be considered.
