The 2022 Buick Enclave AWD models equipped with the 3.6L V6 get a combined 20 MPG. While it won’t win any efficiency awards, this isn’t unexpected for a large, comfortable, and capable family SUV with all-wheel drive. The Enclave isn’t for those obsessed with squeezing every last drop of fuel. It caters to buyers prioritizing space, a smooth ride, and a touch of understated luxury, even if that necessitates accepting middling fuel consumption.

City and highway performance

The EPA estimates the 2022 Buick Enclave AWD achieves 17 MPG in the city and 25 MPG on the highway. The city figure reflects stop-and-go driving, where the Enclave’s weight and larger engine affect fuel economy. The highway number is more respectable, aided by the 9-speed automatic transmission which keeps the engine running at lower RPMs during steady-state cruising. These figures are averages; your actual mileage will vary depending on driving style, traffic, and weather conditions.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2022 Buick Enclave AWD at $2,200. This calculation is based on driving 15,000 miles per year and assumes national average fuel prices. With fluctuating gas prices, that figure offers a benchmark, but keep current fuel costs in mind when budgeting. Expect to spend more if you consistently drive more than 15,000 miles a year or live in an area with higher fuel prices.

Real-world expectations

While the EPA estimates provide a standardized baseline, real-world fuel economy often differs. Enclave owners report a range of MPG figures. Some drivers who frequently engage in short trips, heavy acceleration, or towing can expect to see numbers closer to the city estimate, or even slightly below. Others who primarily drive on the highway with a light foot can often match or even exceed the EPA’s 25 MPG highway rating. The 20 MPG combined figure is reasonably achievable for most drivers who understand the vehicle’s limitations.

How it compares

The Buick Enclave’s fuel economy places it in the middle of its competitive set. The Acura MDX SH-AWD, with its 3.5L V6, is similar to the Enclave’s 20 MPG combined. The Infiniti QX60, sporting a similar engine configuration, also gets about that number. A Volvo XC90 B6 AWD, even with its smaller turbocharged and supercharged 2.0L engine, achieves a marginally better 22 MPG combined. The difference is minimal, and the other vehicles sometimes require premium fuel which offsets some or even all of that economy bump. Buyers cross-shopping these vehicles are likely factoring in other aspects beyond fuel economy, such as interior design, technology, and brand prestige, as detailed in ENCLAVE MPG across all years.

Tips to maximize efficiency

While the Enclave isn’t inherently fuel-efficient, there are several ways to improve its gas mileage in your day-to-day use. One simple strategy is to drive smoothly. Avoid aggressive acceleration and hard braking, as these actions consume more fuel. Anticipate traffic flow and maintain a consistent speed whenever feasible. The Enclave isn’t a sports car, and it rewards a relaxed driving style with better fuel economy.

Keep your tires properly inflated. Underinflated tires increase rolling resistance, forcing the engine to work harder and burn more fuel. Check your tire pressure regularly and inflate them to the recommended levels found on the sticker inside the driver’s side doorjamb. This small adjustment can make a noticeable difference in the long run. Tire pressure also affects handling and tire wear, so it’s a win-win situation.

Reduce excess weight. Carrying unnecessary items in the vehicle adds weight, which in turn reduces fuel economy. Remove any items from the trunk or cargo area that you don’t need on a regular basis. While the Enclave is designed to haul cargo, being mindful of what you’re carrying directly impacts overall fuel consumption.

Consider using cruise control on the highway. Cruise control helps maintain a constant speed, minimizing unnecessary acceleration and deceleration. This can lead to improved fuel economy, especially on long trips. However, use it carefully in hilly terrain, as the system may downshift aggressively to maintain speed and negate some of the fuel-saving benefits. Buick also provides all Buick fuel economy data, allowing you to examine the choices available across their lineup.
