23 MPG combined might not set any records, but consider the 2017 GMC Terrain AWD with the 2.4L four-cylinder for what it is: a comfortable, practical, and surprisingly capable small SUV designed for those who prioritize a smooth ride and confident all-weather traction over outright fuel efficiency. This isn’t a Prius competitor; it’s a workhorse designed to haul kids, groceries, and weekend gear with minimal fuss.

City and highway performance

The EPA estimates tell a straightforward story. The 2017 Terrain AWD with the 2.4L engine gets 20 MPG in the city and 28 MPG on the highway. The city figure reflects the engine’s need to work a bit harder in stop-and-go traffic, especially with the added weight and drag of the all-wheel-drive system. However, the highway number is close to 30 MPG, indicating that the six-speed automatic transmission does a decent job of keeping the engine at its best for cruising. This split performance is ideal for suburban dwellers who primarily use the Terrain for errands and school runs but also appreciate its ability to handle longer road trips with reasonable efficiency.

Annual fuel cost

The EPA estimates that the annual fuel cost for the 2017 GMC Terrain AWD 2.4L is $1,900. This figure is calculated based on driving 15,000 miles per year, with a mix of city and highway driving, using the national average fuel price when the EPA testing was conducted. Keep in mind that actual fuel costs will vary depending on individual driving habits and local fuel prices.

How much time is spent in either city or highway environments also affects cost. Drivers who spend more time in stop-and-go traffic or live in areas with higher fuel costs can expect to pay more than the EPA estimate. On the other hand, those who primarily drive on the highway may see a slightly lower annual fuel bill. Always check for local rebates and fuel card options to maximize your potential savings.

Real-world expectations

While the EPA figures provide a good baseline, real-world fuel economy can often differ. Many owners report achieving figures close to the EPA estimates, especially on longer trips. However, aggressive driving, frequent short trips with cold engine starts, and using the all-wheel-drive system in dry conditions will all negatively impact fuel consumption. Those who frequently load the Terrain with passengers and cargo should also expect a dip in MPG.

Conscientious driving habits and proper maintenance are key to achieving the best possible fuel economy.

How it compares

Compared to its competitors, the 2017 GMC Terrain AWD 2.4L occupies a middle ground in terms of fuel efficiency. The Honda CR-V AWD, for example, achieves an EPA-estimated 27 MPG combined with its 1.5L turbocharged engine, offering a noticeable advantage in fuel savings. The Toyota RAV4 AWD typically achieves around 25 MPG combined. Some competing models, like the Jeep Cherokee with its V6 engine, often fall below the Terrain’s numbers. Buyers in this segment are often weighing fuel efficiency against other factors like passenger space, cargo capacity, and available features; the Terrain tries to strike a balance.

Tips to maximize efficiency

Avoid aggressive acceleration and braking. The Terrain’s 2.4L engine is responsive enough for everyday driving, but it doesn’t reward a heavy foot. Smooth, gradual acceleration and anticipating traffic flow can significantly reduce fuel consumption. The Terrain isn’t designed for hot-rod starts, so be gentle and let the engine do its work.

Ensure proper tire inflation. Underinflated tires increase rolling resistance and reduce fuel economy. Check your tire pressure regularly, ideally every few weeks, and inflate them to the recommended levels specified on the driver’s side doorjamb. Even a slight drop in pressure can noticeably impact MPG, so keeping them properly inflated is a simple and effective way to save fuel. Proper tire maintenance helps maintain the tire’s lifespan as well.

Minimize unnecessary weight. Carrying extra cargo adds strain to the engine and reduces fuel efficiency. Remove any items you don’t need, such as sports equipment or tools. The lighter the vehicle, the easier it is for the engine to propel it, resulting in better fuel economy across all driving conditions. Empty the trunk routinely to ensure it only holds essential items.

Use cruise control on the highway. Cruise control helps maintain a consistent speed, which can improve fuel economy on long highway drives. By avoiding fluctuations in speed, you minimize unnecessary acceleration and braking, allowing the engine to operate more efficiently. The consistent throttle input from cruise control optimizes fuel consumption, especially on relatively flat terrain.

Consider disabling all-wheel drive in suitable conditions. The 2017 Terrain’s AWD system, while beneficial in snow and ice, adds weight and drivetrain friction that reduces fuel economy. If your Terrain has the ability to disable AWD manually, use it on dry pavement to eliminate the unnecessary fuel penalty. All Gmc fuel economy data is available for analysis, detailing how various drive configurations can impact your fuel consumption.

The 2017 GMC Terrain AWD 2.4L appeals to those who value a comfortable and confident driving experience over great fuel economy. While not the most fuel-efficient option in its class, it provides a good combination of practicality and all-weather capability. Consider browsing TERRAIN MPG across all years for any used options.
