I had a 2019 GMC Terrain AWD as a rental last week. It returned 31.5 mpg by the trip computer*. Better than I expected considering most of the trip was spent going from sea level to 4,000 feet once or twice a day. This is the 4th time I've had an Equinox or Terrain as a rental and they have returned low 30's every time.

The Terrain and Equinox are back on my radar.

*The first tank was 32.5 mpg by the trip computer and 31.2 hand calculated but that hand calculation includes an unknown number of miles driven by the previous renter.

The second tank was 29.2 hand calculated vs 29.1 on the trip computer

The trip computer showed an average of 26 mpg over almost 10K miles. I have no idea how someone can get that bad of fuel mileage. I got above 30 driving 5 mph over the speed limit most of the time and Hawaii has cities of any size and no traffic congestion to speak of.
