28 MPG combined is an acceptable compromise for the 2024 Subaru Outback AWD 2.5L 4-cyl. It’s not the best in its class, nor will it win any hypermiling contests. However, it is a perfectly acceptable number for a vehicle that prioritizes all-weather capability, cargo space, and a strong image over outright fuel efficiency. Outback buyers aren’t chasing the lowest running costs; they’re seeking adventure and reliability and are willing to trade a few MPGs for those attributes.

City and highway performance

The EPA estimates for the 2024 Outback 2.5L place city driving at 26 MPG and highway cruising at 32 MPG. These numbers reflect the Outback’s naturally aspirated 2.5-liter four-cylinder engine, which prioritizes smooth and predictable power delivery over fast acceleration. The automatic transmission (AV-S8) is well-tuned to the engine’s characteristics, helping to keep it in the optimal rev range for both efficiency and responsiveness. Expect stop-and-go traffic to bring the MPG closer to the EPA estimate in city environments. Highway runs should meet or exceed 32 MPG if driven carefully.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2024 Subaru Outback 2.5L at $1,550. This figure is based on driving 15,000 miles per year and using national average fuel prices. This is an estimate, and actual fuel costs will vary depending on driving habits, the type of driving (more city or highway), and location (fuel prices fluctuate regionally). The $1,550 figure offers a good baseline for budgeting transportation expenses. You can compare this number against all Subaru fuel economy data and those of competitor vehicles to assess relative running costs.

Real-world expectations

While the EPA provides standardized numbers, Outback owners often report that real-world MPG is around the low-to-mid 20s in mixed driving conditions. Aggressive driving styles, frequent hauling of cargo, and the added drag of roof racks and other accessories contribute to this difference, and the Outback’s exceptional AWD system uses some fuel compared to front-wheel drive alternatives. The Outback is built for adventure, and owners often use it in ways that exceed the EPA’s testing parameters. Adjust driving style and be mindful of extra weight if maximizing fuel economy is the top priority.

How it compares

The Outback competes in a crowded segment. The Toyota RAV4, for example, achieves a combined EPA rating of 30 MPG in its standard front-wheel-drive configuration, climbing to 40MPG for the hybrid version. The Honda CR-V fares similarly, with a 28 MPG combined rating for its standard gasoline engine and an even more impressive 40 MPG for the hybrid. The standard RAV4 achieves 30 MPG due in part to its FWD drivetrain. The Outback’s standard AWD system adds weight and complexity that contributes to an MPG dip. All of these alternatives offer comparable utility and practicality at a lower running cost, but they lack the Outback’s adventurous spirit and standard full-time all-wheel drive. Someone considering an Outback prioritizes AWD traction and a comfortable ride, not the absolute best mpg. It is important to compare OUTBACK MPG across all years to understand the fuel economy trends for this model.

Tips to maximize efficiency

Anticipate traffic flow to minimize hard acceleration and braking. The Outback’s automatic transmission will smoothly shift at optimal points, saving fuel as long as you drive in a progressive, predictable manner.

Regularly check and maintain proper tire pressure. Underinflated tires increase rolling resistance, which can significantly reduce fuel economy. Consult the sticker on the driver’s side doorjamb for the recommended tire pressure.

Avoid carrying unnecessary weight in the vehicle. The heavier the load, the more fuel it takes to move it. Remove roof racks or cargo carriers when not in use to reduce aerodynamic drag.

Consider using cruise control on highway drives. Maintaining a consistent speed can improve fuel economy, especially on long journeys. Be mindful of varying road conditions and traffic flow and avoid using cruise control in situations where it may be unsafe.

Ensure that the engine is properly maintained. Regular oil changes, air filter replacements, and tune-ups can help to optimize engine performance and fuel efficiency. Follow the manufacturer’s recommended maintenance schedule.
