Just as a frame of reference, I picked up my 2023 TRX yesterday and drove about 170 miles back to the office - I got 13.6 mpg at 75 mph with cruise control on. From the office to home I got 13.8 mpg - but was definitely taking it easy. Oddly enough, on the way in today, I only got 12.2 mpg. It's raining today and about 15 degrees colder than yday - but odd given that it's the same trip. If anyone is wondering, my trip to/from work should be pretty ideal. It's about 9 miles with speed limits of 45-55 mph with very few lights and the other 11 miles of interstate with 65 mph speed limit. I usually drive about 10 over.
I thought this might be a helpful data point for anyone who was curious.
