What Our Members Are Saying about the Real GMC Terrain MPG

GMC Terrain Fuel Economy: Pros
Year Body/Powertrain Comment
2012 4dr SUV 182-hp 2.4L I4 6-sp 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.
2011 4dr SUV 182-hp 2.4L I4 6-sp shiftable automatic FWD Compared to our current vehicle, we estimated approx. $75/month in fuel savings.
2010 4dr SUV 182-hp 2.4L I4 6-sp shiftable automatic FWD awesome, average is 7.5 liters/100 kms
2010 4dr SUV 182-hp 2.4L I4 6-sp shiftable automatic FWD 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.
2010 4dr SUV 182-hp 2.4L I4 6-sp shiftable automatic AWD 29 highway is good for a vehicle of this size
2010 4dr SUV 182-hp 2.4L I4 6-sp shiftable automatic AWD Main reason for purchasing was we wanted a vehicle that was AWD, could tow small loads and would get reasonable fule mileage.
GMC Terrain Fuel Economy: Cons
Year Body/Powertrain Comment
2011 4dr SUV 301-hp 3.6L V6 6-sp shiftable automatic AWD We are getting about 14 miles to the gallon. Worst 3.0 litter i have ever owned
2011 4dr SUV 182-hp 2.4L I4 6-sp shiftable automatic AWD doesnt get near what they say it will get. worse then the last 2.4 I-4 engine I had.(2006 HHR)
2011 4dr SUV 182-hp 2.4L I4 6-sp shiftable automatic FWD You get 32 mph/gal ONLY if you set the cruze and stay at or below 55mph.
2010 4dr SUV 301-hp 3.6L V6 6-sp shiftable automatic FWD Have less than 500 miles on vehicle and just got 24 mpg on highway with cruise set at 68.
2010 4dr SUV 182-hp 2.4L I4 6-sp shiftable automatic AWD 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.
2010 4dr SUV 182-hp 2.4L I4 6-sp shiftable automatic FWD Vehicle doesn't come close to 32 mpg highway spec. Average is 26-27 mpg. Big disappointment given the marketing of the vehicle.
