A combined 28 MPG won’t break any records, but in the 2020 Buick Encore GX AWD with its 1.3L three-cylinder engine, it’s a reasonable compromise. This isn’t a fuel-sipping hybrid. It’s a slightly upsized compact SUV designed for urban dwellers and empty-nesters who prioritize extra cargo space, available all-wheel drive, and near-luxury features over outright efficiency. Its buyers aren’t hypermilers, but they also aren’t willing to sacrifice practicality to save a few dollars at the pump.

City and highway performance

The 2020 Buick Encore GX AWD delivers an EPA-estimated 26 MPG in the city and 29 MPG on the highway. The small difference between city and highway figures suggests the 9-speed automatic transmission manages the engine’s output well in both environments. In urban settings, the turbocharger provides adequate low-end torque, helping to maintain momentum without excessive throttle input. On the highway, the numerous gears allow the engine to cruise at lower RPMs, improving fuel economy during longer journeys. Its character on the open road is relaxed, never rushed, perfectly matching its mission as a comfortable, stylish hauler.

Annual fuel cost

According to the EPA, the annual fuel cost for the 2020 Buick Encore GX AWD is $1,550. This figure is based on driving 15,000 miles per year and using national average fuel prices. Changes to typical mileage habits or location will affect the annual expenditure. If you drive significantly fewer miles or live in an area with lower fuel costs, your annual expense will be lower. High mileage drivers or those living where fuel is more expensive should expect to pay more. This benchmark offers a starting point for assessing the overall operating expenses of owning this particular vehicle.

Real-world expectations

The EPA estimates provide a standardized benchmark, but real-world fuel economy often varies based on driving habits, traffic conditions, terrain, weather, and vehicle maintenance. In the case of the 2020 Buick Encore GX AWD, expect that number of 28 MPG to change. Aggressive acceleration, frequent stop-and-go traffic and sustained high-speed driving will likely decrease fuel economy. Smooth acceleration, consistent speeds, and proactive maintenance (such as proper tire inflation) can help drivers approach or even slightly exceed the EPA estimates. Using all-wheel drive, particularly in dry conditions when it’s not needed, will negatively impact fuel economy.

How it compares

The 2020 Buick Encore GX AWD competes in a crowded segment of small SUVs. The Mazda CX-30 with its standard 2.5L engine and available AWD achieves around 25 MPG combined, making the Buick slightly more efficient on paper. A comparable Chevrolet Trailblazer AWD, which shares a platform with the Encore GX, also offers similar fuel economy in real-world testing, but some drivers prefer the Buick’s slightly more upscale interior. The Honda HR-V, while not offering the same level of premium features, delivers around 28 MPG combined with AWD. For the Encore GX buyer, the slight disadvantage in fuel economy versus the HR-V is often justified by the Buick’s better ride quality and more refined cabin.

Tips to maximize efficiency

Minimize idling. The Encore GX’s small engine loses efficiency quickly when idling. If you anticipate being stopped for more than a minute, engage the auto stop/start system (if equipped and desired), or simply turn off the engine. The restart is quick and smooth, and it can save a noticeable amount of fuel over time, especially in stop-and-go city driving.

Maintain optimal tire pressure. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressures regularly (ideally every two weeks) and inflate them to the recommended level indicated on the door jamb sticker.

Use cruise control wisely. On long highway drives, cruise control can help maintain a consistent speed and improve fuel economy. However, avoid using cruise control in hilly areas, as the transmission may downshift frequently to maintain speed, negating any potential fuel savings. In those situations, modulating the throttle yourself is usually more efficient.

Avoid unnecessary cargo. The Encore GX offers a decent amount of cargo space, but carrying excessive weight will decrease fuel economy. Remove any unnecessary items from the vehicle, especially heavy objects in the trunk or cargo area. A lighter vehicle requires less energy to accelerate and maintain speed.

Consider front-wheel drive if you don’t need AWD. If all-wheel drive is not a necessity, either for weather or typical road conditions, opting for a front-wheel-drive model of the Encore GX will yield better fuel economy. The added weight and drivetrain losses associated with AWD invariably reduce efficiency, even when it’s not actively engaged.
