29 highway is good for a vehicle of this size
2010 4dr SUV 182-horsepower 2.4L I4

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-horsepower 2.4L I4

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

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

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.
 

GMC Terrain Gas Mileage (MPG)

Unlike other fuel economy surveys, TrueDelta's Real-World Gas Mileage Survey includes questions about how and where a car was driven. So you can get an idea of the GMC Terrain's real-world MPG based on how and where you drive a car.
