24 MPG combined is what you get for practical all-weather performance in the 2019 Buick Regal TourX AWD 2.0L 4-cyl. This figure won’t set any efficiency records, but it reflects a conscious tradeoff that the TourX buyer willingly accepts: maximizing cargo capacity and year-round security without venturing into the world of traditional SUVs.

City and highway performance

The EPA estimates suggest 21 MPG in the city and 29 MPG on the highway for this configuration of the Regal TourX. The city figure is where most drivers will feel the engine working, especially with the added weight of the all-wheel-drive system. Stop-and-go traffic will drag down fuel economy, while consistent highway cruising allows the turbocharged 2.0L engine to stretch each gallon a bit further. The 8-speed automatic transmission helps keep the engine in its most efficient range at higher speeds, but even on the open road, the TourX’s aerodynamics aren’t as slick as a sedan’s, impacting overall consumption.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2019 Buick Regal TourX AWD 2.0L 4-cyl is $2,400. This calculation is based on driving 15,000 miles per year and using national average fuel prices. Individual spending could vary significantly based on driving habits, local fuel costs, and the proportion of city versus highway miles driven. Drivers who frequently encounter heavy traffic or drive aggressively will likely exceed this estimate, while those with longer commutes at consistent speeds may see a slightly lower figure. The price of premium fuel will also shift that figure.

Real-world expectations

The EPA’s numbers provide a good baseline, but some owners see figures that deviate slightly. Drivers who prioritize smooth acceleration and anticipate traffic flow are more likely to meet or even exceed the EPA’s estimates. If you frequently use the engine’s full power for quick acceleration or haul heavy loads, expect to see fuel economy dip below the advertised numbers.

The all-wheel-drive system, while beneficial for traction, constantly adds a small amount of drag, which impacts overall fuel consumption, and some drivers have noted lower figures on winter blends of gasoline.

How it compares

The Regal TourX occupies a unique niche, straddling the line between wagons and crossovers. A key competitor is the Subaru Outback, a vehicle with a similar mission of all-weather practicality. The Outback, equipped with its standard 2.5L engine, achieves a combined MPG of 29. While it boasts efficiency gains, it is smaller inside than the Buick. A similarly equipped Volvo V60 Cross Country is more luxurious, but delivers a combined MPG of around 25, depending on the model year and engine configuration. Even compact SUVs like the Honda CR-V (around 30 MPG combined with its 1.5L turbo and AWD) offer superior gas mileage, but lack the cargo volume and driving dynamics of the Buick. Considering all Buick fuel economy data, the value of the TourX remains high, especially for buyers seeking a well-equipped wagon with ample space.

Tips to maximize efficiency

Use gentle acceleration whenever possible. The Regal TourX’s turbocharger can be tempting to engage frequently, but controlling the throttle and avoiding sudden bursts of speed will significantly improve fuel economy, especially in city driving. This approach not only saves gas but also reduces wear and tear on the drivetrain.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Regularly check and inflate your tires to the recommended pressure listed on the driver’s side doorjamb. A simple tire gauge is an essential tool for any Regal TourX owner concerned about fuel efficiency.

Minimize unnecessary weight. Hauling around heavy cargo that is not needed will reduce fuel range. Clear out any unnecessary items from the cargo area and passenger compartment to lighten the load. Even small increments of weight reduction can contribute to noticeable improvements in MPG over time for the Buick Regal TourX.

Use cruise control on the highway. Maintaining a consistent speed with cruise control helps optimize fuel consumption by avoiding fluctuations in acceleration. Set your desired speed and let the vehicle manage the throttle, particularly on long highway stretches. This can be especially helpful on hilly roads.

Consider using a fuel additive from time to time. While not a magic bullet, certain fuel additives can help keep fuel injectors clean and improve combustion efficiency. Regularly cleaning the system this way will keep it operating at peak efficiency. Follow the manufacturer’s instructions carefully when using any fuel additive.
