TrueDelta Reviews the Real Gas Mileage of the GMC Terrain

GMC Terrain Real Gas Mileage: Cons
YearComment
2010 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

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

Fuel economy was a big factor in purchase decision. Real world mileage not really close to 32 epa rating, but still pretty decent for a big, comfy station wagon-esque vehicle. see full GMC Terrain review

Main reason for purchasing was we wanted a vehicle that was AWD, could tow small loads and would get reasonable fule mileage. see full GMC Terrain review

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

Vehicle doesn't come close to 32 mpg highway spec. Average is 26-27 mpg. Big disappointment given the marketing of the vehicle. see full GMC Terrain review

First trip fuel mileage 618 km on 65 liters of fuel. Terrian has 30000 KM on it. Trip was driven at 100 KM very little idle time. see full GMC Terrain review
