The 2017 Buick Regal with the 2.4L four-cylinder engine gets 23 MPG combined. While fuel efficiency isn’t the main reason to buy this car, it offers a comfortable, well-equipped sedan with a touch of luxury at a reasonable price. It’s an acceptable trade-off for those who value a smooth ride and a quiet cabin over maximizing gas mileage.

City and highway performance

The EPA estimates 19 MPG in the city and 30 MPG on the highway. The highway number is respectable for long-distance driving. The city number shows the engine isn’t as efficient in stop-and-go traffic. The six-speed automatic transmission tries to compensate, but the engine displacement means it works harder when accelerating or in congested areas. This means more frequent trips to the gas station for city drivers. Consider this if your daily commute is mostly in the city.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2017 Buick Regal 2.4L at $1,900. This assumes 15,000 miles per year and the national average fuel price at the time of testing. Your actual fuel costs may differ based on your driving, fuel type, and location, as regional fuel prices vary. However, $1,900 is a useful benchmark for comparing fuel costs to other vehicles in the same class. Check current fuel costs to estimate how they’ll affect your budget.

Real-world expectations

EPA estimates are a standard, but real-world fuel economy often varies. Expect slightly lower numbers than the EPA estimates, especially in mixed driving. Aggressive acceleration, idling, and heavy loads will hurt fuel efficiency. However, consistent highway driving at moderate speeds can meet or exceed the EPA’s 30 MPG highway rating. Monitoring your driving and doing regular maintenance can help you maximize each gallon.

How it compares

The 2017 Buick Regal 2.4L has average fuel economy compared to other cars of that time. For example, the Honda Accord 2.4L got better gas mileage, achieving 27 MPG combined. The Toyota Camry with its 2.5L engine often had better numbers than the Regal too. However, these more efficient options might not have the Regal’s quieter cabin. The Regal’s available 2.0L turbo engine offered more power but used more gas. The 2.4L engine is therefore a logical choice. Be sure to examine all Buick fuel economy data for more information. Those wanting the lowest running costs might consider hybrid vehicles or smaller, more fuel-efficient sedans, but the Regal isn’t in that market. Those interested in other year models of this specific vehicle can review the REGAL MPG across all years.

Tips to maximize efficiency

Gentle acceleration helps maximize fuel economy in the 2017 Buick Regal 2.4L. Avoid sudden speed increases and maintain consistent throttle. This reduces engine strain and fuel use, especially in the city.

Regular maintenance is key. Keep your tires inflated to the correct pressure. Under-inflated tires increase rolling resistance and reduce MPG. Scheduled oil changes, air filter replacements, and spark plug maintenance also help engine performance and fuel economy.

Minimize idling, as the 2.4L engine uses fuel even when stopped. If you’ll be stopped for more than a minute, turn off the engine. Modern cars can handle frequent starts and stops without issues.

Use cruise control on the highway. Cruise control helps maintain a consistent speed, which prevents unneeded acceleration and deceleration. Consistent highway speeds optimize fuel consumption and can help you reach the EPA’s 30 MPG highway estimate.

Consider your cargo, and remove unneeded items from the trunk. Excess weight increases the engine’s workload and reduces fuel efficiency. Only carry what you need to help your Buick get the best MPG.
