25 MPG combined isn’t going to set any records, but it’s a reasonable figure for the 2017 GMC Terrain FWD with the 2.4L four-cylinder engine. This compact SUV isn’t trying to be a fuel-sipping hybrid; it’s designed to offer a comfortable, practical, and stylish alternative to larger, thirstier SUVs. Buyers prioritize interior space, a smooth ride, and GMC’s traditionally upscale image. Fuel economy, while important, isn’t always the top priority.

City and highway performance

The EPA estimates the 2017 GMC Terrain FWD 2.4L at 21 MPG in the city and 31 MPG on the highway. That city figure reflects the Terrain’s weight and the engine’s need to work harder in stop-and-go traffic. The 31 MPG highway rating is more appealing and achievable on long trips, but it’s crucial to maintain a steady speed and avoid aggressive acceleration to see those results. The six-speed automatic transmission does its best to keep the engine in its sweet spot, but ultimately, it’s the driver’s habits that will make the biggest difference in real-world economy. Knowing the TERRAIN MPG across all years can help you make the right choice.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2017 GMC Terrain FWD 2.4L is $1,750. This figure is based on driving 15,000 miles per year and using national average fuel prices. This is just an estimate; your actual fuel costs will vary depending on your driving habits, the type of driving you do (city vs. highway), and the price of gasoline in your area. If you live in a city with high gas prices, you can expect to pay more than $1,750 per year to fuel your Terrain. Conversely, if you drive mostly highway miles and maintain a light foot on the accelerator, you may be able to beat that estimate, but $1,750 is the approximate baseline.

Real-world expectations

While the EPA estimates provide a useful baseline, real-world fuel economy often differs. Terrain drivers should realistically expect to see combined MPG figures somewhere in the low- to mid-20s, perhaps closer to the EPA estimate in warmer months with minimal AC use. Factors like mountainous terrain, frequent short trips, and a heavy foot on the accelerator can easily decrease the average. Conversely, consistent highway driving at or near the speed limit will yield the best results. The Terrain’s trip computer can provide a running average MPG figure, allowing drivers to monitor their fuel consumption and adjust their driving habits accordingly, so keep an eye on it.

How it compares

Compared to competitors, the 2017 GMC Terrain’s fuel economy is fairly average for its class. The Honda CR-V, a perennial favorite, manages a more impressive 28 MPG combined in its FWD models. The Toyota RAV4, another strong contender, achieves 26 MPG combined in its non-hybrid FWD variants. Even the Nissan Rogue, known for its comfort and available third-row seating (on some models), can reach 29 MPG combined with front-wheel drive. The Terrain’s fuel economy isn’t a standout feature, which means buyers who are considering it should do so because of its styling, features, or brand appeal. Potential buyers should also consider looking at all Gmc fuel economy data.

Tips to maximize efficiency

Avoid abrupt acceleration. The 2.4L engine in the Terrain responds well to smooth, gradual inputs. Pushing the accelerator hard to merge or pass will quickly burn through fuel. Anticipate traffic flow and maintain a consistent speed whenever possible. Minimize stop-and-go driving, as it is the biggest fuel economy killer for this vehicle.

Keep your tires properly inflated. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressure regularly and inflate them to the recommended level, which can be found on a sticker inside the driver’s side doorjamb. This is a simple but effective way to improve fuel economy by a small but noticeable margin.

Reduce unnecessary weight. Carrying extra cargo in your Terrain adds weight and reduces fuel economy. Remove any items you don’t need, such as sports equipment or tools. Even small amounts of weight can add up over time, so keeping your vehicle as light as possible will help you save on gas.

Use cruise control on the highway. Cruise control helps maintain a consistent speed, which can improve fuel economy. Use cruise control on long stretches of highway to avoid speeding up and slowing down unnecessarily. Be mindful of terrain, however, as cruise control can sometimes be less efficient on hilly roads.
