Starting with 825 miles on the odometer and 40mpg, i quickly learned that speed, hills and towing were the biggest hits to fuel economy on my 2021 HEV's first big trip. I drove from Tucson to Boise, Idaho, to pick up a 850lb teardrop camper i'd chosen to match the Sportage. It does best around 55mph, but highway speeds or mountain climbs bring the numbers down. With the trailer in tow, i still averaged about 35mpg ranging from 25 to 35 depending on terrain. Towing in Smart mode felt smooth and powerful, even on hills, though it did take longer to stop. The auto wipers and headlights worked well most of the time, and overall, the Sportage handled the trip so easily it went almost exactly how i'd imagined.
