17 MPG combined isn’t going to win the 2016 Buick Enclave AWD any fuel efficiency awards, but for families who need its generous passenger and cargo space, it’s an accepted compromise. The Enclave is a large, comfortable, and well-equipped crossover designed for hauling kids, cargo, and occasionally towing a small camper or boat. Fuel economy isn’t the top priority for buyers in this segment, but understanding the Enclave’s consumption is still critical to budgeting for ownership.

City and highway performance

The EPA estimates the 2016 Buick Enclave AWD at 15 MPG in the city and 22 MPG on the highway. That 7 MPG difference shows where this vehicle struggles most: stop-and-go traffic. The Enclave’s weight, along with the energy required to repeatedly accelerate from a standstill, takes a toll. On the open road, the 3.6L V6 settles into a more efficient cruising speed, explaining the higher highway figure. Still, 22 MPG is hardly groundbreaking, and it reflects the aerodynamic compromises inherent in a large, boxy SUV designed for maximum interior volume. The six-speed automatic transmission, while smooth, lacks the fuel-saving gear ratios of more modern eight, nine, or ten-speed units.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,600 for the 2016 Buick Enclave AWD. This figure is based on driving 15,000 miles per year, split roughly 55% city and 45% highway, and using national average fuel prices. Remember that your actual fuel costs may vary significantly depending on your driving habits and local fuel prices. For example, those with heavy city commutes or who frequently tow will likely exceed this estimate.

Drivers who primarily use the Enclave for long highway trips might see a slightly lower annual fuel bill. It’s a helpful starting point, but not a definitive predictor of your personal fuel expenses.

Real-world expectations

While the EPA estimates offer a standardized benchmark, real-world fuel economy often differs. Enclave drivers often report figures slightly below the EPA numbers, especially in combined driving. Expect to average somewhere between 15 and 19 MPG in mixed driving conditions. However, aggressive driving, frequent short trips, and cold weather can further reduce fuel economy. Careful driving habits and primarily highway miles can yield results closer to the EPA’s 22 MPG highway estimate. Checking online forums dedicated to the Enclave can give you a range of real-world fuel economy experiences from other owners. Always consult ENCLAVE MPG across all years.

How it compares

The 2016 Buick Enclave’s fuel economy places it squarely in the middle of its competitive set. A 2016 Acura MDX SH-AWD, for example, manages 19 MPG combined, a noticeable improvement. A 2016 Ford Explorer with the 3.5L V6 and available 4WD is rated at 19 MPG combined. Even the Infiniti QX60, often praised for its luxury and smoothness, achieves around 21 MPG combined. These seemingly small differences can add up to hundreds of dollars in fuel savings over the course of a year. For consumers prioritizing fuel efficiency, these alternatives might be a better choice, especially given the increasingly strict emissions regulations and rising fuel costs. It is important to see all Buick fuel economy data before making a purchase decision. Some models may vary substantially.

Tips to maximize efficiency

Given the Enclave’s size and weight, gradual acceleration is crucial. Avoid stomping on the gas pedal, as this forces the engine to work harder and consume more fuel. Instead, accelerate smoothly and steadily to maintain optimal fuel efficiency.

Proper tire inflation is another simple yet often overlooked factor. Underinflated tires increase rolling resistance, which decreases fuel economy. Check your tire pressure regularly and inflate them to the recommended pressure listed on the driver’s side door jamb.

Minimize idling time. Modern engines consume fuel even when stationary. If you anticipate being stopped for more than a minute, turn off the engine. Restarting the engine consumes far less fuel than remaining idle. This applies particularly in situations like waiting in school pick-up lines or drive-throughs.

Reduce unnecessary weight. The Enclave is already a heavy vehicle, so avoid carrying unnecessary items in the cargo area or roof rack. Extra weight increases the engine’s workload and lowers fuel economy. Clean out the vehicle regularly to remove any items you don’t need.

Consider the benefits of cruise control, especially on highway drives. Maintaining a consistent speed helps the engine operate at its most efficient, maximizing fuel economy. Avoid sudden acceleration or braking while using cruise control, and be prepared to disengage it in heavy traffic or inclement weather.
