Gmc has grossly overestimated the mpg on terrains. They get no where near the miles that they advertised.
The sole reason we bought a 4 cylinder terrain was for the advertised MPG . We feel cheated and will never buy a GMC again.

I have had the Terrain for almost 3 months and I never even come close to getting the MPG that GMC claims the Terrain gets. The best I have ever gotten was 23.2 and that was on a road trip with all highway miles. I used to have a hybrid escape until my husband totalled it so I know how to drive a car to maximize gas mileage. I looked for areplacement for months for a SUV or crossover with good gas mileage. I finally decided on the 2012 4cyl FWD GMC Terrain because it claimed to get 32 MPG on the highway. I typically average about 18-20 MPG. I would have NEVER purchased this car if I had known that I would never come close to the estimated MPG. I will never buy a GMC again...they are dishonest. Sign me up for the class action!
