If you are shopping for a new SUV, gas mileage is probably on your mind. Fuel costs, commute length, weekend driving, and family travel can all affect which SUV makes the most sense.
The good news is that Buick’s current SUV lineup gives you several efficient options. Whether you want a compact crossover for daily driving or a three-row SUV for family space, there is likely a fuel-efficient Buick SUV that fits your routine.
For shoppers around Frankenmuth, Saginaw, Birch Run, Bay City, and Mid-Michigan, comparing Buick SUVs with the best gas mileage is a smart first step before scheduling a test drive.
Buick SUV MPG Comparison
Here is a simple look at current Buick SUV fuel economy estimates.
| Buick SUV | EPA-Estimated MPG | Seats | Best Fit |
|---|---|---|---|
| Buick Envista | 28 city / 32 highway | Up to 5 | Drivers who want the most efficient Buick SUV option |
| Buick Encore GX | Up to 30 city / 31 highway with FWD | Up to 5 | Shoppers who want small SUV flexibility and strong fuel economy |
| Buick Envision | 22 city / 28 highway | Up to 5 | Drivers who want more space and a more premium compact SUV feel |
| Buick Enclave | 20 city / 25 highway with FWD | Up to 7 | Families who need three-row seating and more passenger room |
Fuel economy can vary by drivetrain, trim, options, traffic, weather, and driving habits. Still, this table gives you a helpful starting point when comparing the Buick SUV lineup.
Buick Envista: The Most Efficient Buick SUV
If fuel economy is your top priority, the Buick Envista should be near the top of your list. The 2026 Envista offers an EPA-estimated 28 MPG city and 32 MPG highway.
That makes Envista a strong choice for commuters, first-time Buick shoppers, and drivers who want SUV style without moving into a larger vehicle. It has a sleek profile, comfortable seating for up to five, and the kind of efficiency that can help reduce fuel stops during everyday driving.

Buick Encore GX: Small SUV Efficiency With Extra Flexibility
The Buick Encore GX is another strong option for shoppers who care about fuel economy. Depending on configuration, the 2026 Encore GX offers up to an EPA-estimated 30 MPG city and 31 MPG highway with front-wheel drive. Available all-wheel drive models are rated at 26 MPG city and 28 MPG highway.
That makes the Encore GX a practical fit if you want a small SUV that is easy to drive, comfortable for daily use, and flexible enough for errands, commuting, and weekend plans.
It is also worth comparing if you want available all-wheel drive for added confidence during Michigan weather, but still want to keep fuel economy in mind.

Buick Envision: More Space While Staying Efficient
The Buick Envision gives shoppers more room and a more upscale compact SUV feel while still keeping fuel economy reasonable. The 2026 Envision is rated at an EPA-estimated 22 MPG city and 28 MPG highway.
It does not match the Envista or Encore GX in pure MPG, but that is not really the point. Envision is a good fit if you want more interior space, a quiet cabin, refined styling, and useful technology while staying in a manageable SUV size.
For drivers who want a comfortable SUV for daily driving around Frankenmuth and longer trips across Michigan, Envision can be a strong middle option.

Buick Enclave: Three-Row Space With Practical MPG
The Buick Enclave is the largest SUV in the Buick lineup. It seats up to seven passengers, which makes it a better fit for families, carpooling, road trips, and drivers who need more passenger and cargo flexibility.
The 2026 Enclave with front-wheel drive is rated at an EPA-estimated 20 MPG city and 25 MPG highway. For a three-row SUV, that gives shoppers a practical balance of space and efficiency.
If you need the extra row, the Enclave may make more sense than choosing a smaller SUV just for MPG. Fuel economy matters, but so does having enough room for your family, luggage, sports gear, and daily life.

Which Fuel-Efficient Buick SUV Fits You?
The right Buick SUV depends on more than the MPG number. Think about how many people you carry, how much cargo space you need, whether you want available AWD, and how much time you spend on the highway.
| If You Want… | Start With… |
| The most efficient Buick SUV | Buick Envista |
| A small SUV with strong MPG and available AWD | Buick Encore GX |
| More space in a compact SUV | Buick Envision |
| Three-row seating for family needs | Buick Enclave |
| A balance of MPG, comfort, and everyday usability | Envista or Encore GX |
| More passenger room and road-trip comfort | Envision or Enclave |
If you drive mostly around town, the Envista or Encore GX may be easier to live with day to day. If you need more space for family travel, Envision or Enclave may be the better fit.
Gas Mileage Is Only Part of the Decision
Fuel economy is important, but it should not be the only factor you compare. A smaller SUV may save more at the pump, but a larger SUV may be the better choice if you need more seats, more cargo room, or more comfort for longer drives.
It also helps to think about your normal week. Do you drive mostly to work and back? Do you take long highway trips? Do you need room for kids, pets, luggage, or sports equipment? Do you want available all-wheel drive for Michigan weather?
Once you answer those questions, it becomes easier to choose the right fuel-efficient Buick SUV.
