The 2019 GMC Terrain FWD 2.0L gets 24 MPG combined, a perfectly acceptable fuel economy rating for what it is. Acceptable, but not stellar. It’s not a hybrid or a compact hatchback; it’s a comfortable, practical, and stylish small SUV aimed at buyers who prioritize features and a refined driving experience over squeezing every last mile from a gallon of fuel. These buyers appreciate the Terrain’s upscale interior, quiet cabin, and user-friendly technology, and they’re willing to trade ultimate thriftiness for those qualities.

City and highway performance

The EPA estimates the 2019 Terrain FWD 2.0L at 22 MPG in the city and 28 MPG on the highway. The city figure reflects the realities of stop-and-go traffic, with the Terrain’s engine working harder to accelerate from a standstill. The 28 MPG highway rating indicates steady-state cruising, where the 9-speed automatic transmission can select an optimal gear for fuel efficiency. These figures represent the front-wheel-drive model; opting for all-wheel drive will typically decrease fuel economy by a few MPG. These numbers are adequate for errand runs and highway road trips.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2019 GMC Terrain FWD 2.0L is $2,400. This figure is based on driving 15,000 miles per year and using the national average fuel price at the time the EPA performed its testing. Your actual fuel costs will vary depending on your driving habits, the type of driving you do, and the prevailing gasoline prices in your area. Stop-and-go driving will raise that number. Frequent long highway trips will reduce it.

Real-world expectations

While the EPA estimates provide a useful benchmark, real-world fuel economy can differ. Many owners report achieving figures close to the EPA’s, but factors such as driving style, terrain, and weather conditions can all have an impact. Aggressive acceleration, frequent high-speed driving, and carrying heavy loads will all reduce fuel economy. Conversely, adopting a smoother driving style, avoiding unnecessary idling, and ensuring proper tire inflation can help you achieve or even exceed the EPA’s estimates. Owners who carefully manage their driving habits can often see results very close to the official EPA numbers. Other factors, such as regular maintenance, can help stretch those gas dollars as well.

How it compares

In the competitive small SUV segment, the 2019 GMC Terrain FWD 2.0L’s fuel economy is broadly comparable to its rivals. For example, the Honda CR-V FWD 1.5L turbo achieves an EPA-estimated 28 MPG combined. The Toyota RAV4 FWD offers up to 30 MPG combined in its non-hybrid form. A comparable Mazda CX-5 with its standard 2.5L naturally aspirated engine delivers around 28 MPG combined in FWD guise. However, these competitors often target a slightly different buyer: those who value ultimate fuel efficiency above all else. Many Terrain buyers are drawn by its interior appointments, technology, and overall comfort, and they accept slightly lower MPG numbers in order to get all desired features.

Tips to maximize efficiency

The Terrain’s 2.0L turbocharged engine can be sensitive to driving style. Avoid aggressive acceleration and hard braking, as these habits can significantly reduce fuel economy. Consistent and gentle acceleration is key to maximizing MPG. A smooth and steady driving style will help the transmission stay in higher gears and keep the engine operating in its most efficient range.

Keep your tires properly inflated. Check your tire pressure regularly and inflate them to the recommended pressure listed on the sticker inside the driver’s side door. Underinflated tires increase rolling resistance, which negatively impacts fuel economy. A simple tire pressure gauge and a few minutes of your time can make a noticeable difference.

Minimize idling. The Terrain burns fuel even when it’s stationary and idling. If you anticipate being stopped for more than a minute, it’s generally more fuel-efficient to turn off the engine. Modern engines are designed to be restarted easily and efficiently, so there’s no need to let the engine run unnecessarily. Also, reduce the amount of weight you carry in the vehicle. Extra weight increases the burden on the engine, which in turn affects the TERRAIN MPG across all years.

Use cruise control on the highway. Cruise control helps maintain a consistent speed, which can improve fuel economy on long drives. Avoid constantly speeding up and slowing down, as this wastes fuel. Let the cruise control system manage the throttle for optimal efficiency.

Ensure your vehicle is properly maintained. Regular maintenance, such as oil changes and air filter replacements, can help your Terrain run more efficiently. A well-maintained engine will deliver better fuel economy than one that’s neglected. Follow the manufacturer’s recommended maintenance schedule to keep your Terrain in top condition.
