2016 GMC Terrain Real Gas Mileage: Cons
Year	Body/Powertrain	Comment
2015	4dr SUV 301-horsepower 3.6L V6 6-speed shiftable automatic AWD	Fuel economy, for a vehicle over 4,000lbs, and a 300hp V6 engine, is going to be low. But at between 15-18mpg, for suburban driving, it seems a bit low. I wanted to the V6 so it would not struggle, and I did that knowing the MPG's were not great, but I hoped it would be better on the highway. What I found most disappointing, was that with the V6, you don't get an "economy" switch. The 4 cylinder version does, but not the V6. Why does this matter? Because with a V6, with much more power than a 4 cylinder, using economy mode would not feel bad. On the Terrain, with the 4 cylinder you are starting with less, so taking away from less isn't alwyas good. But taking away from the V6, would not be as impacting. see full GMC Terrain review
