Fuel Economy in the Buick SUV Lineup
Envista: Efficient Highway Cruiser
Envista pairs a 28/32 MPG estimate with five-passenger seating and a low, coupe-inspired profile. It is front-wheel drive, so shoppers who require AWD should compare another model.
Encore GX: Engine and Drivetrain Choices
Encore GX offers the lineup’s broadest efficiency comparison: two engine possibilities in FWD form and available AWD with the 1.3-liter engine.
Envision: Premium Two-Row Balance
Envision’s 22/28 MPG estimate accompanies a more powerful 2.0-liter turbo engine, AWD and greater maximum cargo room than Buick’s smaller two-row SUVs.
Enclave: Three-Row Capability
Enclave’s FWD estimate reaches 20/27 MPG while providing seven-passenger seating, a 328-horsepower turbo engine and available trailering capability.
How FWD and AWD Affect Buick MPG
Front-Wheel Drive
FWD commonly produces the stronger published fuel-economy result because the vehicle carries less drivetrain hardware. Envista is FWD, while Encore GX and Enclave offer FWD configurations.
All-Wheel Drive
AWD can provide additional traction when conditions require it, but its extra hardware can reduce the published MPG figure. Tires and driver decisions still matter in winter weather.
Estimate Annual Fuel Cost with Your Own Numbers
A small MPG difference matters more to a high-mileage driver. Use this simple calculation instead of relying on a generic fuel-price assumption.
Annual miles ÷ expected MPG × local fuel price = estimated annual fuel cost
Use a realistic combined MPG based on your city/highway mix, then repeat the calculation for each vehicle you are comparing.
Choose Efficiency Without Ignoring Your Needs
| Priority | Start with | Reason to compare it |
|---|---|---|
| Highest highway estimate | Envista | 32 MPG highway in its published FWD rating |
| Highest city estimate shown | Encore GX 1.2L FWD | 30 MPG city; confirm configuration availability |
| Small Buick with available AWD | Encore GX | Lets shoppers compare FWD efficiency with AWD traction |
| More power and two-row premium space | Envision | Balances 2.0-liter turbo performance, AWD and cargo flexibility |
| Seven seats or maximum cargo room | Enclave | Adds the passenger and capability benefits of a larger three-row SUV |
