The 2019 GMC Terrain FWD with its 1.6L diesel engine gets 32 MPG combined, making it one of the most fuel-efficient compact SUVs. This isn’t about raw power or off-road prowess. It provides a comfortable, stylish, and economical ride for those who want good gas mileage and lower running costs. Buyers are typically commuters, small families, or empty-nesters who want more space without spending too much on fuel.

City and highway performance

The Terrain’s EPA estimates show 28 MPG in the city and 39 MPG on the highway. The city MPG reflects the engine’s stop-and-go performance, managed by its six-speed automatic transmission. The highway figure stands out. This 39 MPG makes the Terrain a good choice for those driving long distances on road trips or commutes. The diesel engine’s efficiency shines on the open road, using less fuel to maintain cruising speeds. It’s a big improvement over gas-powered competitors in similar conditions.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2019 GMC Terrain FWD 1.6L at $1,750. This is based on driving 15,000 miles per year and using national average fuel prices. Your actual fuel costs will vary based on your driving habits and local fuel prices. Driving hard and taking frequent short trips will lower fuel economy, increasing costs. Smooth acceleration and consistent highway speeds will help you get closer to, or even better, the EPA estimate.

Real-world expectations

The EPA provides a benchmark, but real-world MPG can differ. Terrain drivers often report highway numbers that match or beat the EPA’s 39 MPG rating, especially on flat roads and with careful driving. The city MPG can be harder to achieve, particularly in busy areas. However, most owners find the combined MPG to be a realistic result of the vehicle’s overall efficiency, saving money compared to other compact SUVs with less efficient gas engines.

How it compares

The 2019 GMC Terrain 1.6L diesel’s fuel economy is excellent for a compact SUV. The Honda CR-V gets about 28 MPG combined in its standard gasoline form. The Toyota RAV4 gets similar numbers. Even hybrid versions of the RAV4 get around 40 MPG combined, slightly better than the Terrain’s highway figure, but cost more. The Mazda CX-5 typically returns around 25 MPG combined with its standard engine. For buyers who want great gas mileage without buying a hybrid or electric vehicle, the Terrain’s diesel engine offered a budget-friendly option, as can be seen by exploring all Gmc fuel economy data.

Tips to maximize efficiency

The diesel engine in the 2019 Terrain responds well to smooth, gradual acceleration. Avoid quick starts and hard braking, as these use more fuel and strain the engine. Watching traffic and keeping a consistent speed helps the engine run best, especially on the highway.

Correct tire inflation is important for good fuel economy. Underinflated tires create more resistance, which makes the engine work harder and use more fuel. Check your tire pressure and inflate them to the manufacturer’s level found on the doorjamb.

Reduce extra weight inside the vehicle. Extra cargo puts strain on the engine, reducing fuel economy. Remove items you don’t need to carry, especially heavy objects, to improve efficiency across TERRAIN MPG across all years.

Use cruise control on the highway. Keeping a constant speed with cruise control helps the engine run better, saving fuel on long drives. Avoid using cruise control in hilly areas, as the vehicle may downshift often, wasting fuel.

Regular maintenance is key to good fuel economy. Keep the engine tuned and change the air filter. A clean air filter helps the engine breathe, improving fuel efficiency. Routine maintenance keeps your Terrain running at its best.
