26 MPG combined isn’t going to set any records, but it represents a reasonable compromise for buyers prioritizing space, all-weather traction, and a touch of rugged styling in a compact SUV. The 2019 GMC Terrain AWD with the 1.5L turbo engine targets a specific type of buyer: someone who wants more than just basic transportation but isn’t willing to sacrifice practicality for pure fuel efficiency.

City and highway performance

The EPA estimates for the 2019 GMC Terrain AWD 1.5L are 24 MPG in the city and 28 MPG on the highway. The city figure reflects the realities of stop-and-go driving where the small-displacement turbo engine works harder, using its power reserves more often. The 28 MPG highway number is more attainable on longer trips where the nine-speed automatic transmission can settle into its higher gears, allowing the engine to cruise relatively effortlessly. These numbers showcase the typical tradeoff: slightly lower city MPG due to the weight and all-wheel-drive system, offset by respectable highway efficiency. The 1.5L engine, while adequate, needs to work a bit to move the Terrain’s mass, especially when fully loaded with passengers or cargo.

Annual fuel cost

The EPA estimates an annual fuel cost of $1,700 for the 2019 GMC Terrain AWD 1.5L. This figure is based on driving 15,000 miles per year, with a certain percentage of those miles driven in the city and the rest on the highway, and using a national average fuel price.

The actual cost may be higher or lower depending on individual driving habits, local fuel prices, and the specific mix of city versus highway driving. Someone who primarily drives in heavy city traffic will likely exceed the $1,700 estimate, while someone who mostly commutes on the highway would probably spend less. Understanding the assumptions behind this figure will help you better calculate your own expected fuel expenses. But $1,700 is what the EPA’s standardized testing yielded.

Real-world expectations

While the EPA figures provide a baseline, real-world fuel economy often varies. Expect to see numbers within a few MPG of the official estimates, but don’t be surprised by fluctuations depending on driving style, terrain, and weather conditions. Aggressive acceleration and frequent hard braking will negatively impact your fuel consumption. Similarly, driving in hilly areas or during cold winters, which require more engine power, can reduce MPG. Owners who prioritize fuel efficiency and drive conservatively will likely see figures closer to the EPA estimates. If you are regularly pushing the Terrain to its dynamic limits, expect fuel economy to suffer, such as when using the available towing capacity regularly or navigating steep inclines.

How it compares

In the competitive compact SUV segment, the 2019 GMC Terrain AWD 1.5L’s fuel economy places it roughly in the middle of the pack. The Honda CR-V AWD with its 1.5L turbo manages a slightly better 29 MPG combined. The Toyota RAV4 AWD, particularly the hybrid version, achieves significantly higher numbers, with the hybrid delivering over 40 MPG combined.

On the other hand, some competitors, like the Jeep Compass 4×4 with its 2.4L engine, offer comparable or slightly lower fuel economy, around 25 MPG combined. The efficiency of other AWD models can be checked on all Gmc fuel economy data. Buyers need to understand the level of practicality these vehicles allow, that often justifies the slight MPG trade-off. These figures are critical for buyers who need AWD or are drawn to the Terrain’s particular styling and features, but who still want to keep an eye on running costs. Buyers who need to compare TERRAIN MPG across all years can find additional information to contextualize their purchase decision.

Tips to maximize efficiency

Given the Terrain’s small-displacement turbo engine, smooth and gradual acceleration is key to maximizing fuel economy. Avoid aggressive starts and heavy throttle inputs, especially in city driving. Let the turbocharger spool up gradually rather than demanding instant power bursts, because the engine will use more fuel pumping air to deliver that extra boost.

Regular maintenance, including timely oil changes and air filter replacements, ensures the engine runs efficiently. Dirty oil or a clogged air filter can increase engine friction and reduce performance, leading to lower fuel economy. Stick to the manufacturer’s recommended maintenance schedule to keep the engine in top condition.

Tire pressure plays an important role in fuel efficiency. Underinflated tires increase rolling resistance, forcing the engine to work harder. Check your tire pressure regularly and maintain it at the recommended level, which can be found on the door jamb sticker. Correct tire pressure not only improves fuel economy but also extends tire life.

Minimize unnecessary weight in the vehicle. Extra cargo adds to the Terrain’s overall weight, which reduces fuel efficiency. Remove any items you don’t need, especially heavy objects in the trunk or cargo area. A lighter vehicle requires less engine power to accelerate and maintain speed. Removing roof racks when unneeded also helps reduce aerodynamic drag.
