TrueDelta Reviews the Real Gas Mileage of the 2012 GMC Terrain

2012 GMC Terrain Real Gas Mileage: Cons
YearComment
2011 On a positive note, the larger V6 earns the same EPA fuel economy ratings as the old one. On a less positive note, it also earns the same fuel economy ratings as the much larger, 4,850-pound Acadia: 16 city, 23 highway. In suburban driving the trip computer reported high teens to low twenties, a few mpg below lighter, more compact competitors. The four-cylinder gets 22/32 with FWD, 20/29 with AWD, but many owners have failed to approach these numbers in the real world. see full GMC Terrain review

2012 GMC Terrain Real Gas Mileage: Pros

2012 4dr SUV 182-horsepower 2.4L I4
6-speed shiftable automatic AWD
Although I have never seen this truck get the estimated fuel economy it boasts about in advertising, considering the shear mass of it and it's breadbox front end, with the I4 the fuel economy is very good considering it is a heavy little beast with AWD. I can average 700 kms. out of a tank of fuel no problem and on longer jaunts have seen it break 800 kms. If you are one of those people who complain about fuel consumption in this truck- you should have bought a Prius... because for what it is, it is exceptional on fuel. Try a different brand of fuel for a while, some brands have more additives and burn quicker. see full GMC Terrain review
