22 MPG combined isn’t going to win any awards for lower fuel costs, but for the 2015 Buick Regal AWD 2.0L, it paints a picture of priorities. This isn’t a Prius competitor; it’s a comfortable, slightly sporty sedan offering the added security of all-wheel drive. The buyer for this Regal appreciates a touch of luxury, a quiet ride, and the confidence to tackle snowy or wet conditions. Fuel economy is a consideration, but it’s not the dominating factor.

City and highway performance

The EPA estimates of 19 MPG in the city and 27 MPG on the highway accurately reflect the Regal’s driving dynamics. The city figure suffers because of the weight of the all-wheel-drive system and the demands placed on the 2.0L turbocharged four-cylinder engine when accelerating from a standstill. On the open road, however, the Regal’s six-speed automatic transmission settles into a more efficient gear, allowing the engine to cruise comfortably. The highway MPG is respectable, even if it falls short of class-leading numbers. Remember that these figures are achievable when driven conservatively; more aggressive driving will certainly see fuel consumption rise.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2015 Buick Regal AWD 2.0L at $2,000. This figure is calculated using a national average fuel price and assuming 15,000 miles of driving per year. It’s a useful benchmark for comparing running costs between different vehicles, but individual expenses will vary based on your specific driving habits and local fuel prices. If you predominantly drive short distances in the city or have a lead foot, expect your annual fuel bill to exceed this estimate.

If you primarily use the Regal for highway commuting and practice efficient driving techniques, you might spend less. Always check current gas prices where you live to estimate your individual annual costs.

Real-world expectations

While the EPA figures provide a useful comparison tool, real-world fuel economy often differs, and the 2015 Buick Regal AWD 2.0L is no exception. Expect to see figures slightly below the EPA estimates, especially in mixed driving conditions. Factors such as traffic congestion, weather conditions, and driving style can all negatively impact fuel consumption. Owners who prioritize fuel efficiency report achieving numbers closer to the EPA’s estimates, but those who enjoy the Regal’s turbocharged power tend to see lower MPG figures. Always check owner forums dedicated to the REGAL MPG across all years for a better understanding of real-world fuel efficiency.

How it compares

The 2015 Buick Regal AWD 2.0L competes in a crowded segment of mid-size sedans, many of which offer better fuel economy. For example, the similarly equipped 2015 Acura TLX SH-AWD with a 2.4L engine achieves a combined 25 MPG. Even the larger, more powerful 2015 Nissan Maxima manages around 25 MPG combined. However, the Buick Regal offers the turbocharged performance and available all-wheel drive that some buyers prioritize over outright fuel efficiency. If fuel economy is your top priority, the Ford Fusion Hybrid delivers significantly better mileage, but it lacks the luxury aspirations and AWD capability of the Regal. All Buick fuel economy data is available for comparison.

Tips to maximize efficiency

Gentle acceleration is key to saving fuel in the Regal. The 2.0L turbo engine delivers plenty of power when you need it, but avoid aggressive starts and hard acceleration, especially in city driving. Using a light foot on the accelerator will minimize fuel consumption and is important if you find yourself doing a lot of stop-and-go driving.

Monitor your tire pressure regularly. Underinflated tires increase rolling resistance, which forces the engine to work harder, reducing fuel economy. Check the tire pressure specification decal, usually located on the driver’s side doorjamb, and maintain the recommended pressure. Doing so will also improve tire life and handling.

Minimize idling time. Leaving the engine running while stationary consumes fuel without covering any distance. If you’re waiting for more than a minute, turn off the engine. Modern vehicles are designed to restart quickly and efficiently, and extended idling wastes precious fuel.

Reduce unnecessary weight. Carrying extra weight in the vehicle increases fuel consumption, so remove any unnecessary items from the trunk and passenger compartment. Extra weight forces the engine to work harder, which can also negatively impact MPG.

Consider using cruise control on the highway. Maintaining a consistent speed minimizes speed fluctuations, which wastes fuel. Cruise control helps keep the vehicle at a steady pace, improving fuel efficiency on long drives. It’s particularly effective on relatively flat stretches of highway.
