The 2023 Subaru Outback AWD with the 2.5L 4-cylinder engine achieves 28 MPG combined, a figure that reflects the core mission of this wagon: providing all-weather capability and ample cargo space without sacrificing respectable fuel efficiency. Given the Outback’s standard all-wheel drive and rugged design, this MPG is an important consideration for buyers who want practicality and adventure readiness.

City and highway performance

The EPA estimates the 2023 Subaru Outback 2.5L will achieve 26 MPG in the city and 32 MPG on the highway. The city rating is influenced by the vehicle’s weight and the all-wheel-drive system, which inherently requires more energy to operate compared to a front-wheel-drive setup. The highway rating benefits from the Outback’s aerodynamic profile (for a wagon) and the efficient tuning of the continuously variable transmission (CVT). Those seeking even better highway numbers should consider the turbocharged 2.4L engine, which strangely manages the same figure in real-world use.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 Subaru Outback 2.5L to be $1,550. This figure is based on driving 15,000 miles per year and using national average fuel prices. The calculation provides a standardized benchmark for comparing fuel costs across different vehicles. However, your actual fuel costs will vary depending on your driving habits, local fuel prices, and the type of driving you do. If you primarily drive in the city or frequently engage the Outback’s off-road capabilities, you can expect to spend more than the EPA estimate of $1,550.

Real-world expectations

While the EPA provides a useful standard, real-world fuel economy can vary significantly. Outback owners often report figures close to the EPA estimates, but there are things to consider. Aggressive driving, frequent short trips in cold weather, and hauling cargo will all reduce fuel efficiency. Conversely, gentle acceleration, consistent highway speeds, and proper tire inflation can help achieve or even exceed the EPA numbers. The Outback’s CVT transmission is programmed to prioritize fuel efficiency, but spirited driving will undoubtedly impact your mileage. The type of terrain you typically drive on will impact real-world results as well.

How it compares

The Subaru Outback 2.5L competes with a range of crossover SUVs and wagons. The Toyota RAV4, a popular compact SUV, achieves an EPA-estimated 30 MPG combined in its non-hybrid form, making it slightly more fuel-efficient than the Outback. However, the RAV4 lacks the Outback’s standard all-wheel drive and its ground clearance. The Honda CR-V, another strong contender, posts a combined MPG of 30 MPG as well. The CR-V offers a similar level of practicality and interior space, but Subaru buyers often prioritize the reliable appeal and standard AWD of the Outback. Those considering the Outback should also look at Subaru’s own Forester, which is more compact and delivers 29 MPG combined.

Tips to maximize efficiency

Monitor your tire pressure regularly. Underinflated tires increase rolling resistance, which reduces fuel economy. The proper tire pressure is listed on a sticker inside the driver’s side doorjamb. Keeping your tires properly inflated is one of the simplest ways to improve gas mileage in the Outback.

Avoid aggressive acceleration and braking. The Outback’s CVT transmission is designed to optimize fuel efficiency, but it can’t compensate for lead-footed driving. Gentle acceleration and anticipating stops will help you conserve fuel.

Minimize idling. Modern engines do not need to warm up for extended periods. Excessive idling wastes fuel and contributes to emissions. If you’re stopped for more than a minute, turn off the engine.

Reduce cargo weight. Carrying unnecessary weight in the Outback will decrease fuel economy. Remove any items you don’t need from the cargo area and passenger compartment. Pay close attention to roof racks and cargo boxes as well, especially when not in use.

Consider using cruise control on the highway. Maintaining a consistent speed can improve fuel efficiency, especially on relatively flat stretches of road. This allows the CVT to function optimally at its most efficient ratio.
