26 MPG combined isn’t going to win any fuel-sipping awards, but it’s a figure the 2021 Buick Encore AWD 1.4L 4-cyl delivers consistently, appealing to a specific buyer. This isn’t a performance SUV, it’s a comfortably sized, slightly elevated, and easily maneuverable vehicle geared toward urban dwellers and empty-nesters who prioritize ease of use and a touch of premium feel over outright efficiency. These buyers accept the fuel economy because it comes packaged with qualities they value more, like the available all-wheel drive and the quiet, comfortable ride Buick is known for. To understand the Encore’s fuel economy, you have to understand its mission.

City and highway performance

The EPA estimates for the 2021 Buick Encore AWD are segmented as 24 MPG in the city and 29 MPG on the highway. The lower city figure reflects the realities of stop-and-go traffic, where the small 1.4L turbocharged engine has to work harder to repeatedly accelerate the Encore’s mass. That said, 24 MPG in city driving is serviceable and a key element of the Encore’s value for city residents. The 29 MPG highway number is more respectable, showing that the Encore settles into a relatively efficient cruise once it achieves speed. It allows for reasonably economical longer trips, even if it’s not class-leading.

Annual fuel cost

The EPA calculates the estimated annual fuel cost for the 2021 Buick Encore AWD at exactly $1,700. This figure is based on driving 15,000 miles per year, using a blend of city and highway driving, and factoring in national average fuel prices. Keep in mind that this is just an estimate, your actual fuel costs will vary depending on your driving habits, the type of roads you typically drive on, and the price of gasoline in your area. Aggressive driving, for example, will push that $1,700 figure higher, while primarily highway driving might lower it slightly.

Real-world expectations

While EPA ratings provide a standardized benchmark, real-world fuel economy can often deviate. Encore drivers report figures that are close to the EPA estimates, but slight variations are almost always expected. Those who primarily drive in congested urban environments may see numbers slightly lower than the 24 MPG city rating. Meanwhile, drivers who routinely undertake long highway stretches might experience figures closer to or even slightly above the 29 MPG highway rating. Consistent driving habits and regular maintenance play an important role in achieving the best possible fuel economy.

How it compares

The Buick Encore competes in a crowded subcompact SUV segment where fuel economy is a key battleground. The front-wheel-drive version of the Encore improves slightly on the AWD model’s numbers. Compared to the closely related Chevrolet Trax, which offers similar performance and fuel economy, the Encore differentiates itself with a more premium interior and improved sound deadening. Other competitors, such as the Honda HR-V (around 28 MPG combined), offer marginally better combined fuel economy, but lack the Encore’s near-luxury aspirations. The Mazda CX-3 (around 29 MPG combined for front wheel drive models) is more fun to drive, but some find its smaller cargo area restrictive. Ultimately, the Encore’s 26 MPG combined figure represents a trade-off that its target buyers are willing to make for its specific blend of size, features, and comfort.

Tips to maximize efficiency

Gentle acceleration is key in the Encore. The 1.4L turbo engine responds well to a light foot, and avoiding aggressive starts will noticeably improve fuel consumption, especially in city driving. Think smooth and steady, rather than quick bursts of speed.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, forcing the engine to work harder and burn more fuel. Check your tire pressure regularly and inflate them to the recommended pressure listed on the sticker inside the driver’s side doorjamb. This is a simple step that can provide a measurable improvement in fuel economy.

Minimize idling. Letting the engine idle for extended periods, especially in cold weather, wastes fuel. If you’re going to be stopped for more than a minute or two, it’s generally more efficient to turn off the engine. The Encore restarts quickly and easily, so there’s little downside.

Reduce unnecessary weight. Carrying around excess gear in the trunk or backseat adds weight to the vehicle, which in turn reduces fuel economy. Take a few minutes to declutter your Encore and remove any items you don’t need. Even small weight reductions can add up over time.

Consider your drive mode (if equipped). Some Encore trims offer selectable drive modes. Experiment to see if a specific “eco” mode helps you manage your fuel expenditure without excessively impacting performance. Remember to also check all Buick fuel economy data and ENCORE MPG across all years.
