The 2027 GMC Terrain AWD fits buyers who want a compact SUV body and all-wheel drive without moving to an electric powertrain. Its gasoline engine and automatic transmission keep the setup familiar.

Its defining EPA figure is 25 MPG combined. That single number gives a practical starting point for mixed city and highway driving.
25 MPG combined
The Terrain AWD is rated at 24 MPG in the city and 28 MPG on the highway. City trips use the lower figure; steady highway travel is represented by the higher one.
Tailpipe emissions are listed at 356 grams of CO2 per mile.

Use 25 MPG for side-by-side shopping

For drivers who want AWD in a small SUV
This Terrain suits a buyer looking for a gasoline-powered small SUV with all-wheel drive and an automatic transmission. Its split city and highway ratings help set expectations for everyday routes.
Mileage versus all-wheel drive
The 24 MPG city rating is lower than the 28 MPG highway rating, so frequent stop-and-go driving will not match the highway figure. The vehicle also carries a 356-gram-per-mile tailpipe CO2 figure.
You get all-wheel drive in a small SUV, but fuel use remains a central running cost at the listed $2,700 per year.
A straightforward AWD SUV choice
Choose the 2027 GMC Terrain AWD if all-wheel drive and small-SUV format matter more than minimizing gasoline spending. Its 25 MPG combined rating gives a clear baseline, while the $2,700 annual fuel estimate makes the ongoing cost easy to budget. Drivers whose miles are mostly highway may see results closer to 28 MPG; mostly urban use points toward 24 MPG.
