24 MPG combined isn’t going to win any hypermiling awards, but for the 2019 Buick Regal AWD with its 2.0L turbocharged engine, it’s a reasonable compromise between performance, all-weather traction, and fuel efficiency. This isn’t a Prius competitor; it’s a comfortable, stylish sedan or wagon that offers a touch of luxury and sure-footedness, especially appealing to buyers in colder climates. Its fuel economy is considered acceptable by its target audience because it delivers the driving refinement and features they prioritize.

City and highway performance

The EPA estimates the 2019 Buick Regal AWD will achieve 21 MPG in the city and 29 MPG on the highway. The lower city figure reflects the reality of stop-and-go traffic, where the 2.0L engine works harder to accelerate the car’s weight from a standstill. The AWD system, while providing added grip, also adds weight and drivetrain friction that contribute to decreased fuel economy compared to front-wheel-drive models. On the open road, the 8-speed automatic transmission helps the Regal maintain a more efficient speed and optimized RPM, leading to the higher highway rating. The 29 MPG highway figure is achievable with steady cruising and minimal aggressive acceleration.

Annual fuel cost

According to the EPA, the annual fuel cost for the 2019 Buick Regal AWD is estimated at $2,400. This figure is calculated based on driving 15,000 miles per year, assuming a national average fuel price. This number offers a standardized way to compare the Regal’s running costs against other vehicles, but individual experiences may vary significantly depending on local fuel prices, driving habits, and the type of driving done each year.

Real-world expectations

While the EPA provides a useful benchmark, real-world fuel economy often differs. Aggressive driving, frequent short trips, and prolonged idling will all negatively impact MPG. Conversely, careful driving habits like smooth acceleration, maintaining a steady speed, and minimizing unnecessary braking can help owners approach or even exceed the EPA estimates in some situations. Drivers who frequently use the Regal for long highway commutes might find that their average MPG is closer to the 29 MPG highway rating, while those who primarily drive in congested urban areas may see figures closer to or even below the 21 MPG city rating.

How it compares

The Regal’s fuel economy places it in a specific competitive set. For example, the Acura TLX with SH-AWD and its 2.4L engine achieves a similar 24 MPG combined. The Subaru Legacy 2.5i, with its standard all-wheel-drive system, boasts a slightly higher 27 MPG combined. This difference of just a few MPG can be a consideration for budget-conscious buyers. Also, you may wish to review all Buick fuel economy data directly on FuelEconomyHub.com. These fuel economy comparisons matter because Regal buyers are often cross-shopping other mid-size sedans and wagons with available AWD, seeking the best balance of fuel efficiency, features, and driving characteristics.

Tips to maximize efficiency

Minimize short trips. The 2.0L turbo engine is less fuel-efficient when cold. Combining multiple errands into a single trip allows the engine to reach its optimal operating temperature, improving fuel economy. This is especially true in colder weather where the engine takes longer to heat up.

Check tire pressure regularly. Underinflated tires increase rolling resistance, reducing fuel economy. Ensure your tires are inflated to the manufacturer’s recommended pressure, which can be found on a sticker inside the driver’s side doorjamb. Properly inflated tires also improve handling and extend tire life.

Avoid aggressive acceleration and braking. The Regal’s turbocharged engine delivers plenty of power, but using it excessively consumes more fuel. Anticipate traffic flow and maintain a steady speed. Smooth and gradual acceleration can significantly improve fuel efficiency. Also, be sure to check the REGAL MPG across all years to see historical trends.

Reduce unnecessary weight. Carrying extra weight in the car increases fuel consumption. Remove any items you don’t need from the trunk and back seat. Even small amounts of added weight can impact fuel economy, especially during city driving.
