The 2019 Buick Enclave FWD models equipped with the 3.6L V6 get 21 MPG combined. This number won’t set any efficiency records, but it’s a compromise many buyers are willing to make for the Enclave’s strengths: a spacious third row, comfortable ride, and a touch of near-luxury appeal at a price below many European competitors. This isn’t for hypermilers, but for families who prioritize a smooth, drama-free driving experience and practical seating for seven or eight.

City and highway performance

The EPA estimates the 2019 Buick Enclave FWD achieves 18 MPG in the city and 26 MPG on the highway. The city figure reflects the demands of stop-and-go traffic, where the Enclave’s weight and engine displacement become more pronounced. The highway number is more respectable.

At a steady cruising speed, the nine-speed automatic transmission helps the Enclave settle into a relatively efficient gear, allowing it to cover long distances without emptying the fuel tank too quickly. Loading up the Enclave with passengers and cargo will reduce these figures, and so will aggressive driving habits.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2019 Buick Enclave FWD to be $2,100. This calculation is based on driving 15,000 miles per year and national average fuel prices. Your actual costs may vary depending on your driving habits and local fuel prices, but this figure provides a benchmark for comparing the Enclave’s fuel expenses to those of other vehicles. This is a factor for families on a budget, but one balanced against the vehicle’s size and functionality.

Real-world expectations

While the EPA provides standardized fuel economy estimates, real-world MPG often differs. Drivers who frequently encounter heavy traffic, steep hills, or who drive aggressively are likely to see lower numbers. Those who primarily drive on the highway and maintain a gentle pace may find they can match or even slightly exceed the EPA’s estimates.

The Enclave’s trip computer can provide real-time and average fuel economy data, which can be helpful in monitoring your driving habits and making adjustments to improve efficiency.

How it compares

Within the three-row SUV segment, the 2019 Buick Enclave FWD is in the middle for fuel economy. The Honda Pilot boasts an EPA-estimated 20 MPG city and 27 MPG highway for its front-wheel-drive models, making it a slightly more efficient choice. The Chevrolet Traverse, which shares a platform with the Enclave, achieves similar EPA estimates. However, moving up to competitors like the Acura MDX with its available SH-AWD system, you’ll typically find fuel economy closer to 19 MPG combined.

A Lincoln Aviator, particularly with its plug-in hybrid powertrain, offers vastly different fuel economy potential, trading expense for efficiency. For those seeking improved fuel economy, exploring options like the Toyota Highlander Hybrid (36 MPG combined) becomes necessary. Each of these choices involves tradeoffs in terms of price, features, and overall driving experience.

Tips to maximize efficiency

The Enclave’s 3.6L V6 is responsive, but it also thrives on smooth, consistent throttle inputs. Avoiding sudden acceleration and hard braking will help the engine and transmission operate more efficiently, particularly in city driving. Anticipating traffic flow and maintaining a steady speed can significantly improve fuel economy.

Proper tire inflation is important for maximizing fuel efficiency. Check your tires regularly and inflate them to the pressure recommended on the doorjamb sticker. Underinflated tires create more rolling resistance, which forces the engine to work harder and consume more fuel.

Excess weight reduces fuel economy. Remove any unnecessary items from the Enclave’s cargo area and passenger compartment. Carrying around extra gear adds to the vehicle’s overall weight and impacts its efficiency.

When possible, use cruise control on the highway. This feature helps maintain a consistent speed, minimizing fluctuations in throttle input and improving fuel economy. Be mindful of traffic conditions and adjust your speed accordingly.

Consider using the Enclave’s “Tour” driving mode when appropriate. This mode optimizes the vehicle’s settings for fuel efficiency by adjusting throttle response and shift points. It’s a useful tool for maximizing MPG on long highway trips. For a deeper dive, take a look at ENCLAVE MPG across all years, or review all Buick fuel economy data
