21 MPG combined is what you can expect from the 2025 Buick Enclave AWD 2.5L 4-cyl. This vehicle prioritizes moving a family and their cargo with Buick comfort and refinement over achieving the absolute best fuel economy. Owners are likely prioritizing space, safety, and a touch of near-luxury and accepting the Enclave’s fuel consumption as a trade-off for its capabilities.

City and highway performance

The EPA estimates give a clear picture of the Enclave’s fuel economy. Expect around 19 MPG in the city. This reflects urban driving’s stop-and-go nature, where the 2.5L engine works harder to accelerate. The 8-speed automatic transmission tries to be efficient, but physics creates limitations. The Enclave performs better on the open highway, achieving 24 MPG. At steady cruising speeds, the engine operates more efficiently, and the transmission can settle into its higher gears. This split in MPG ratings reflects the driving patterns of Enclave owners: weekend road trips balanced by weekday errands.

Annual fuel cost

The EPA calculates the annual fuel cost for the 2025 Buick Enclave AWD 2.5L 4-cyl to be $2,100. This is based on driving 15,000 miles per year with a mix of city and highway driving, and using the national average fuel price. This is a useful benchmark, but individual expenses will vary depending on local fuel costs and driving habits. If you drive fewer miles annually, or live in an area with lower gas prices, your fuel expenditure will be lower. Drivers who accelerate quickly or those who frequent higher-priced gas stations may exceed this estimate.

Real-world expectations

EPA estimates are a guide, but your real-world experience with the 2025 Buick Enclave’s fuel economy will likely differ. Factors such as driving style, road conditions, weather, and tire pressure can impact fuel consumption. Aggressive acceleration, frequent braking, and exceeding the speed limit will decrease MPG. A smoother driving style and adhering to speed limits will improve fuel economy. Cold weather can also negatively impact MPG because engines require more fuel to reach operating temperature. Expect your mileage to change throughout the year.

How it compares

The Buick Enclave’s mileage is competitive against other three-row SUVs, but context matters. The Acura MDX SH-AWD manages 19 MPG city, 26 MPG highway representing an advantage on the highway. Some buyers might prefer the Enclave’s interiors. The Volvo XC90 B5 AWD claims 22 MPG combined, and the BMW X5 xDrive40i achieves 23 MPG combined providing better economy. The Kia Telluride, a non-luxury option, offers an EPA-estimated 20 MPG city and 26 MPG highway in AWD guise. The Enclave buyer must weigh these fuel efficiency trade-offs against interior space, luxury, and brand preferences. Remember to compare ENCLAVE MPG across all years to see how this model has evolved.

Tips to maximize efficiency

Monitor your tire pressure regularly. Underinflated tires increase rolling resistance, causing the engine to work harder and burn more fuel. Check the sticker on the driver’s side doorjamb for the recommended tire pressure.

Avoid excessive idling. If you anticipate waiting for more than a minute, turn off the engine. Modern engines restart quickly and efficiently, making it more fuel-efficient to switch off the engine than to idle for extended periods.

Use cruise control on the highway. Maintaining a consistent speed minimizes acceleration and braking, which can improve fuel economy, especially on long drives.

Minimize the use of accessories. Running the air conditioner and using power-draining features like heated seats and rear defrosters can increase fuel consumption. Use them when necessary, but be aware these systems are more efficient in modern vehicles.

Keep up with scheduled maintenance. Regular oil changes, air filter replacements, and tune-ups ensure the engine runs well, which contributes to better fuel economy. Refer to the owner’s manual for the recommended maintenance schedule for your 2025 Buick Enclave AWD 2.5L 4-cyl.
