28 MPG combined isn’t going to win any hypermiling contests, but it’s a respectable figure for the 2018 Buick Encore AWD with its 1.4L turbocharged engine. This isn’t a vehicle bought for class-leading efficiency; it’s a gateway into the Buick brand, offering a slightly elevated driving position, a touch of luxury, and available all-wheel drive in a small, city-friendly package. Buyers prioritize a comfortable ride, quiet cabin, and ease of parking over fuel savings. They’re often downsizing from larger vehicles or seeking a more manageable option for urban environments.

City and highway performance

The EPA estimates the 2018 Buick Encore AWD at 26 MPG in the city and 31 MPG on the highway. This difference, while modest, reflects the nature of the small-displacement, turbocharged engine. In urban driving, the turbocharger is frequently engaged, providing acceleration but also consuming more fuel. On the highway, where the engine can cruise at lower RPMs with less turbo boost, efficiency improves. The Encore’s six-speed automatic transmission is well-matched to the engine’s powerband, contributing to operation and reasonable fuel consumption in both environments.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2018 Buick Encore AWD at $1,550. This figure is based on driving 15,000 miles per year and using national average fuel prices. Your actual fuel costs may vary depending on your driving habits, the type of fuel you use, and prevailing gas prices in your area. Aggressive driving, extended idling, and consistently using premium fuel (though not required) will all increase your fuel expenses. While the EPA provides a standardized benchmark, your personal driving style ultimately determines your real-world fuel budget.

Real-world expectations

The EPA provides a useful benchmark, but owners often report slightly different MPG figures in real-world driving. Weather conditions, tire pressure, and the weight of cargo carried in the vehicle all play a role. Someone consistently driving in stop-and-go traffic will likely see lower figures than those primarily doing highway driving. Consider the EPA estimate a reliable guideline, but understand that individual results can vary based on your specific circumstances with the ENCORE MPG across all years.

How it compares

Compared to other subcompact SUVs with available all-wheel drive, the 2018 Buick Encore’s fuel economy is competitive, but not class-leading. The Mazda CX-3 AWD, for example, achieves 29 MPG combined, offering better fuel economy with a more engaging driving experience. The Honda HR-V AWD manages 28 MPG combined, matching the Encore but with a more spacious interior. The Jeep Renegade 4×4, known for its off-road capability, delivers around 24 MPG combined, sacrificing fuel economy for more rugged performance. These comparisons are critical for buyers who prioritize fuel efficiency, but for Encore buyers, the Buick’s perceived luxury and refinement often outweigh marginal differences in MPG.

Tips to maximize efficiency

Gentle acceleration is key with the Encore’s small turbocharged engine. Avoid hard starts and sudden bursts of speed, as these actions force the turbocharger to work harder and consume more fuel. Smooth, steady acceleration allows the engine to operate more efficiently.

Regularly check your tire pressure and maintain the recommended inflation levels. Underinflated tires create more rolling resistance, which reduces fuel economy. Properly inflated tires also improve handling and extend tire life. Consult the sticker on your driver’s side doorjamb for the correct tire pressure.

Minimize idling time, especially in cold weather. Modern engines warm up quickly, so prolonged idling is unnecessary and wasteful. If you anticipate being stopped for more than a minute, turn off the engine. This simple habit can significantly improve your city MPG.

Reduce unnecessary weight in the vehicle. Extra cargo adds to the load the engine has to carry, decreasing fuel efficiency. Remove any items you don’t need, such as sports equipment or tools. A lighter vehicle requires less energy to move.

Use cruise control on the highway to maintain a consistent speed and avoid unnecessary acceleration and deceleration. This also helps prevent accidentally accelerating to high speeds. Constant speed translates directly to better fuel economy, especially on long trips. Consider checking all Buick fuel economy data for more tips.
