19 MPG combined. That’s the fuel economy for the 2015 Buick Enclave FWD 3.6L V6. It’s a figure that won’t win any awards, but it’s also not a deal-breaker for the Enclave’s target demographic: families who prioritize space, comfort, and a touch of luxury over outright efficiency. These buyers understand they’re making a trade-off, opting for a large three-row SUV that can comfortably haul kids, cargo, and the occasional carpool crew in relative style.

City and highway performance

The EPA estimates the 2015 Buick Enclave FWD at 17 MPG in the city and 24 MPG on the highway. The city figure reflects the Enclave’s weight and the demands of stop-and-go driving, where the 3.6L V6 has to work harder to get the hefty SUV moving. The highway figure is more palatable, indicating the Enclave can achieve decent fuel economy on long road trips where the engine settles into a more efficient cruising speed. The 6-speed automatic transmission is geared to optimize highway efficiency, but it’s ultimately battling the Enclave’s inherent size and aerodynamic profile.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2015 Buick Enclave FWD is $2,300. This calculation is based on driving 15,000 miles per year and using the national average fuel price. It’s a good starting point for budgeting, but keep in mind that your actual fuel costs will vary depending on your driving habits, local fuel prices, and the specific type of fuel you use. While $2,300 might seem high compared to smaller vehicles, it fits within the expected range for a large, three-row SUV that prioritizes passenger and cargo space. You can also review ENCLAVE MPG across all years to compare to other model years of the Enclave.

Real-world expectations

While the EPA estimates provide a standardized benchmark, real-world fuel economy can differ. Enclave owners report achieving figures relatively close to the EPA estimates, particularly on longer highway drives. However, aggressive driving, frequent short trips, and heavy loads will undoubtedly decrease fuel economy. It’s critical to drive with a light foot and maintain consistent speeds to maximize your MPG. Weather conditions such as extreme cold or heat and the use of accessories like air conditioning can also impact fuel efficiency.

How it compares

The 2015 Buick Enclave FWD isn’t a fuel economy leader in its segment, but it’s also not the worst offender. The Acura MDX, for example, with its 3.5L V6 and all-wheel drive, manages around 20 MPG combined. The Infiniti QX60, another popular choice, achieves similar figures, hovering around 21 MPG combined in its front-wheel-drive configuration. The Chevrolet Traverse, mechanically similar to the Enclave, delivers comparable fuel economy, around 17 MPG city and 24 MPG highway, but often comes with a lower price tag. These comparisons are important to the Enclave buyer because they are likely cross-shopping these models based on features, price, and brand reputation. While fuel economy is a consideration, it rarely outweighs the need for space and family-friendly amenities.

Tips to maximize efficiency

Proper tire inflation is key for optimizing fuel economy in the Enclave. Check your tire pressure regularly and inflate to the recommended PSI listed on the driver’s side doorjamb. Underinflated tires increase rolling resistance, which reduces fuel efficiency.

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 idling consumes fuel without any benefit.

Maintain a steady speed on the highway. Using cruise control can help prevent erratic acceleration and deceleration, which waste fuel. Anticipate traffic flow and avoid sudden braking whenever possible.

Regular maintenance is critical for optimal fuel economy in the Enclave. Ensure the engine is properly tuned, the air filter is clean, and the oil is changed according to the manufacturer’s recommendations. A well-maintained engine runs more efficiently.

Consider removing any unnecessary weight from the vehicle. Extra cargo in the trunk or on the roof rack increases the vehicle’s load and reduces fuel economy. Empty out any items you don’t need for your daily commute or trips. If fuel economy is important to you, be sure to review all Buick fuel economy data.
