The 2023 GMC Terrain FWD with its 1.5L turbocharged four-cylinder engine achieves 26 MPG combined, a figure that places it in the middle of the compact SUV segment. This isn’t an exciting number, but it reflects the Terrain’s mission as a comfortable and practical choice for those who prioritize ease of use and a slightly more upscale feel than some of its direct competitors. Terrain buyers are often less concerned with outright fuel efficiency and more interested in a vehicle that offers a comfortable ride, user-friendly tech, and a refined cabin, and 26 MPG satisfies that reasonable need.

City and highway performance

The 2023 Terrain’s EPA ratings break down to 24 MPG in the city and 29 MPG on the highway. The city figure is acceptable for stop-and-go traffic, where the 1.5L engine and nine-speed automatic transmission work well enough together. The engine’s relatively low output means that acceleration can feel strained, especially when fully loaded, but for typical urban driving, it adequately serves its purpose. The highway rating is more commendable. While not class-leading, 29 MPG allows for comfortable long-distance cruising without excessive fuel stops. It’s a rating that reflects the careful calibration of the transmission, which allows the engine to settle into a fuel-efficient RPM range at higher speeds.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 GMC Terrain FWD 1.5L at $1,700. This calculation is based on driving 15,000 miles per year and using national average fuel prices. Keep in mind that this is just an estimate, and your actual fuel costs will vary depending on your driving habits, the type of driving you do (more city vs. highway), and local fuel prices. Aggressive driving, frequent short trips in cold weather, and using premium fuel when it’s not required will all negatively impact your fuel expenses.

Real-world expectations

While the EPA provides a standardized yardstick, real-world fuel economy often deviates. Drivers of the 2023 Terrain should realistically expect to see figures within a few MPG of the EPA estimates, assuming typical driving conditions. Factors like tire pressure, vehicle maintenance, and the weight of cargo can all influence fuel consumption. The Terrain’s relatively small fuel tank capacity will require more frequent visits to the gas station compared to some larger SUVs, even if the MPG figures are similar.

How it compares

The compact SUV segment is fiercely competitive, and fuel economy is often a key consideration for buyers. The Honda CR-V, for example, achieves up to 30 MPG combined in its front-wheel drive variants. Similarly, the Toyota RAV4 offers a 27 MPG combined with its standard gasoline engine. The Mazda CX-5, with its sporty driving dynamics, still manages around 26 MPG combined, matching the Terrain. The Terrain’s 26 MPG makes it about average for its class, and the purchasing decision comes down to other factors like styling, features, and brand preference. A shopper focusing exclusively on saving money at the pump would likely gravitate towards the CR-V or RAV4 hybrids instead. Don’t forget, owners can view TERRAIN MPG across all years to better understand possible fuel economy. Or they can check all Gmc fuel economy data.

Tips to maximize efficiency

Gentle acceleration and smooth braking can have a significant impact on fuel economy. Avoid sudden bursts of speed and anticipate traffic flow to minimize hard braking. The Terrain’s transmission is designed to shift smoothly and efficiently, let it do its job by maintaining a steady throttle input.

Proper tire inflation is important for optimal fuel efficiency. Check your tire pressure regularly and inflate your tires to the recommended pressure listed on the sticker inside the driver’s side door. Under-inflated tires increase rolling resistance, which forces the engine to work harder and consume more fuel.

Avoid unnecessary idling. If you’re stopped for more than a minute, turn off the engine. Modern engines are designed to restart quickly and efficiently, and idling consumes fuel without moving the vehicle. This is especially important in urban environments with frequent stoplights and traffic congestion.

Reduce aerodynamic drag by removing roof racks or cargo carriers when they’re not in use. These accessories can significantly increase wind resistance, especially at highway speeds, which leads to lower fuel economy. Keeping the Terrain’s exterior clean can also subtly improve aerodynamics.

Consider using cruise control on long highway drives. Cruise control helps maintain a consistent speed, which minimizes fluctuations in fuel consumption. The Terrain’s adaptive cruise control system can enhance efficiency by automatically adjusting the vehicle’s speed to maintain a safe following distance.
