18 MPG combined might not impress a Prius owner, but for those considering the 2017 Buick Enclave FWD with its 3.6L V6, it’s an accepted trade-off. Families needing spacious three-row seating, a comfortable ride, and a touch of luxury in a practical package understand this isn’t a fuel-sipping compact. It’s a large, capable vehicle for hauling people and cargo.

City and highway performance

The Enclave’s 15 MPG in the city reflects the challenge of moving over 4,600 pounds through stop-and-go traffic. The 3.6L V6 needs to work to overcome the vehicle’s weight. On the open road, the 22 MPG highway rating is more appealing. This can be achieved during consistent cruising, where the Enclave performs well. The six-speed automatic transmission, while not the most advanced, is tuned for smooth, predictable shifts that prioritize comfort over fuel efficiency. It’s an acceptable compromise for buyers who value a relaxed driving experience.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2017 Buick Enclave FWD at $2,450. This is based on driving 15,000 miles per year and using national average fuel prices. The real-world cost will vary depending on driving habits and local fuel prices. Expect to spend more if you primarily drive in the city or drive aggressively. Those who mostly take long highway trips may see a slightly lower annual fuel bill. Premium fuel is not required, so the estimate is based on regular unleaded gasoline.

Real-world expectations

While the EPA provides a standardized estimate, owner experiences suggest that achieving the stated 18 MPG combined can be a challenge. Many report averaging around 16 MPG in mixed driving conditions. Aggressive acceleration, frequent short trips, and heavy loads will negatively impact fuel economy. However, careful drivers who prioritize smooth acceleration and maintain a steady cruising speed can get closer to the EPA estimates, especially on longer highway journeys. Your mileage may vary. Don’t expect hybrid-like efficiency, but good driving habits can help mitigate the Enclave’s fuel consumption.

How it compares

In the three-row SUV segment, the 2017 Enclave’s fuel economy is in the middle. A 2017 Acura MDX SH-AWD offers a slightly better 21 MPG combined, but costs more and has a sportier feel. The 2017 Honda Pilot, a popular choice, achieves a similar 22 MPG combined in its FWD configuration. Choosing an all-wheel-drive version of the Enclave reduces its fuel economy. Buyers prioritizing fuel efficiency might consider a minivan like the Chrysler Pacifica Hybrid (82 MPGe combined), which is more economical. The Enclave offers a combination of size, comfort, and understated luxury, which outweighs its fuel economy for many.

Tips to maximize efficiency

The Enclave’s V6 responds well to careful driving. Avoid aggressive acceleration and hard braking. Predict traffic and maintain a steady speed, reducing unnecessary fuel consumption and improving your MPG. Regular maintenance, including tire inflation and oil changes, is also important for fuel efficiency.

Ensure tires are properly inflated. Under-inflated tires increase rolling resistance and reduce fuel economy. Check your tire pressure regularly and inflate to the recommended levels found on a sticker inside the driver’s side doorjamb or in your owner’s manual. This can make a big difference.

Reduce unnecessary weight. Carrying heavy cargo adds strain to the engine and reduces fuel economy. Remove non-essential items from the vehicle, especially heavy objects. A lighter vehicle is more efficient. Learn more about all Buick fuel economy data.

Minimize idling. Excessive idling wastes fuel. Turn off the engine if you’re stopped for more than a minute or two. Modern engines restart quickly, so there’s no need to let the engine run unnecessarily. See ENCLAVE MPG across all years.

Consider using cruise control on the highway. Cruise control helps maintain a consistent speed, which can improve fuel economy compared to fluctuating speeds from manual throttle control. This works well on long highway trips where you can maintain a steady pace.
