24 MPG combined in the 2025 Buick Envision AWD with its 2.0L 4-cylinder engine isn’t going to win any fuel efficiency awards, but it represents a reasonable compromise for buyers seeking a comfortable, stylish, and well-equipped compact SUV with all-wheel drive.

City and highway performance

The EPA estimates the 2025 Buick Envision AWD will achieve 22 MPG in the city and 28 MPG on the highway. The city figure reflects the realities of stop-and-go driving, where the Envision’s weight and the inherent inefficiencies of internal combustion engines affect mileage. The highway figure, however, is more respectable.

The nine-speed automatic transmission helps keep the engine in its optimal rev range at cruising speeds, contributing to better gas mileage. For those who prioritize longer trips and highway commutes, the Envision’s highway rating is arguably its strongest selling point from an MPG perspective. Remember that these are EPA estimates. Your actual fuel economy will vary depending on your driving habits, terrain, and weather conditions.

Annual fuel cost

The EPA estimates that the annual fuel cost for the 2025 Buick Envision AWD is $1,800. This calculation is based on driving 15,000 miles per year and using the EPA’s projected national average fuel prices. This number serves as a useful benchmark for comparing the Envision’s running costs against other vehicles in its class and can help buyers factor fuel costs into their overall budget.

Of course, the actual amount you spend on fuel will fluctuate based on prevailing gas prices in your area and your individual driving patterns.

Real-world expectations

While the EPA provides standardized testing results, real-world fuel economy often differs. Aggressive acceleration, frequent braking, and consistently exceeding speed limits will undoubtedly reduce your MPG. On the other hand, smooth driving, anticipating traffic flow, and adhering to posted speed limits can help you approach or even exceed the EPA estimates.

The Envision’s all-wheel-drive system, while beneficial for traction in adverse conditions, also adds weight and complexity, which can slightly decrease fuel efficiency compared to front-wheel-drive models. Regular maintenance, including proper tire inflation and timely oil changes, also plays an important role in maintaining optimal fuel economy.

How it compares

Within the competitive landscape of compact SUVs, the Envision’s fuel economy holds its own, but it’s not a class leader. The Acura RDX SH-AWD, for example, comes in at 21 MPG city / 27 MPG highway / 23 MPG combined.

The Infiniti QX50 AWD fares similarly, with an EPA estimated 22 MPG city / 28 MPG highway / 25 MPG combined. The Lexus NX 350 AWD achieves numbers close to the Envision, at 22 MPG city / 29 MPG highway / 25 MPG combined. These small variations can be important for buyers prioritizing every possible MPG.

The Toyota RAV4 Hybrid absolutely trounces the Envision in real-world MPG, but it comes with a different driving personality, and some buyers simply prefer the Buick’s more conventional luxury experience. Potential buyers should consider all Buick fuel economy data before making a decision.

Tips to maximize efficiency

Take advantage of the Envision’s drive mode selector. Choose the “Tour” mode for everyday driving. This mode optimizes fuel efficiency by adjusting throttle response and transmission shift points. “Sport” mode may be fun, but it also drinks more fuel.

Ensure your tires are properly inflated to the recommended pressure listed on the sticker inside the driver’s side door. Underinflated tires increase rolling resistance, which negatively affects fuel economy. Check your tire pressure regularly, especially during temperature changes.

Avoid unnecessary idling. If you’re stopped for more than a minute, turn off the engine. Modern engines are designed to restart quickly and efficiently, and restarting consumes less fuel than idling for extended periods. This is particularly relevant in city driving.

Minimize your use of accessories like air conditioning and heated seats. These features put an extra load on the engine, increasing fuel consumption. When possible, use the fan or open a window instead of blasting the AC. For ENVISION MPG across all years, be sure to review past models’ specs.

Practice smooth driving techniques. Avoid sudden acceleration and hard braking. Anticipate traffic flow and maintain a consistent speed. The Envision’s turbocharged engine rewards a gentle touch on the accelerator.
