So, if you're commuting, running errands around Poughkeepsie, NY, or heading out on longer trips, understanding how each model stacks up can help you make a smarter decision before you make a decision.
The Buick SUV Lineup at a Glance
Buick currently offers four SUV models in the U.S.: the Envista, Encore GX, Envision, and Enclave. Each is available in Preferred, Sport Touring, and Avenir trims, giving you flexibility when it comes to choosing style and features. The smaller models naturally have an edge in gas milage, but every model has its strengths.
Buick Envista: The Most Fuel-Efficient Option
If gas milage is your No. 1 priority, you want the 2026 Buick Envista.
It gets an EPA estimate of 28 MPG in the city and 32 MPG on the highway. That's impressive for a crossover SUV.
It seats up to 5 and is good for drivers who spend a lot of time in stop-and-go traffic or on the highway. The Envista also comes in Sport Touring and Avenir trims if you want a more stylish or sportier look.
Buick Encore GX: A Close Second
The 2026 Encore GX is another Buick SUV with outstanding gas milage. With front-wheel drive, it gets an EPA estimate of 29 MPG city and 31 MPG highway, very similar to the Envista in average MPG.
The Encore GX offers a bit more interior space than the Envista and is available across the same trim lineup.
Buick Envision and Enclave: Larger and Capable
If you need more space, consider the 2026 Buick Envision and Enclave are worth a look - though they prioritize capacity over fuel economy. The Envision has an EPA estimated gas milage of 22 MPG city and 28 MPG highway, while the Enclave comes in at 20 MPG city and 25 MPG highway with front-wheel drive.
If you need to seat up to 7 passengers, the Enclave is the best SUV for gas mileage among three-row options in the lineup, but the smaller models will save you more at the pump over time.
Which One Is Right for You?
The best answer depends on how you drive and what you need from your vehicle. If maximum fuel efficiency is the goal, the Envista is the choice. If you want a balance between city efficiency and small-SUV practicality, the Encore GX is the best bet. For more space without completely giving up efficiency, the Envision hits a solid middle ground.
