26 MPG combined for the 2025 Subaru Forester Wilderness AWD 2.5L 4-cyl directly reflects its mission: to provide genuine off-road capability and all-weather confidence without demanding punitive trips to the pump. This isn’t a pavement princess; it’s a rugged adventurer, and its fuel efficiency needs to be assessed through that very particular lens. Subaru engineers prioritized sure-footedness and durability, which naturally adds weight and introduces components like a reliable all-wheel-drive system and higher ground clearance. These factors inherently work against outright fuel numbers. Yet, at 26 MPG, it remains a reasonable option for the buyer who values exploration over outright economy, balancing its go-anywhere spirit with everyday livability.

City and highway performance

The EPA figures show the 2025 Forester Wilderness gets 25 MPG in city driving and 28 MPG on the highway. The city number, at 25 MPG, is particularly noteworthy for a vehicle with off-road enhancements. Features like a larger intake, specific gearing revisions, and the additional weight of underbody protection and a lifted suspension often penalize city fuel economy more severely. However, Subaru’s finely tuned 2.5L Boxer engine, paired with the automatic (AV-S8) continuously variable transmission, manages to maintain respectable efficiency even in stop-and-go conditions. The transmission, in particular, plays a critical role, mimicking an 8-speed automatic to optimize power delivery and efficiency. On the highway, the 28 MPG figure is solid, reflecting the flat-four engine’s ability to cruise efficiently at steady speeds. While not class-leading when compared to some front-wheel-drive crossovers, it’s highly competitive among vehicles with standard, full-time all-wheel drive, especially those engineered for true off-pavement performance. This balance ensures that the Forester Wilderness is not only capable of reaching remote destinations but also affordable to drive there and back.

Annual fuel cost

The EPA estimates an annual fuel cost of $1,700 for the 2025 Subaru Forester Wilderness AWD 2.5L 4-cyl. This figure is calculated based on an assumed 15,000 miles driven per year, split between city and highway driving, using national average fuel prices. For a vehicle designed for adventure, this $1,700 annual outlay is a significant factor in the total cost of ownership, translating to roughly $141 per month. Buyers who choose the Forester Wilderness are acutely aware of its utility and reliable capabilities. They accept this annual fuel cost as a reasonable expense for the peace of mind offered by its symmetrical all-wheel drive, elevated ground clearance, and X-MODE traction management system. This is about accessing trailheads, navigating snowy passes, or hauling gear for weekend excursions, all while maintaining a predictable and manageable fuel budget. The $1,700 annual cost underlines Subaru’s commitment to delivering a highly capable vehicle that remains affordable to operate for its target audience.

Real-world expectations

In the real world, owners of the 2025 Forester Wilderness can generally expect to see fuel economy figures that align closely with the EPA’s 26 MPG combined, provided they drive within reasonable parameters. Subaru powertrains, particularly the 2.5L Boxer, are known for their consistent real-world performance relative to EPA estimates. However, the “Wilderness” aspect of this vehicle inevitably invites conditions that can impact fuel efficiency. Frequent use of its X-MODE, sustained off-road driving at lower speeds, or aggressive acceleration and braking on challenging terrain will naturally lead to figures below the 26 MPG average. The vehicle’s all-terrain tires, while excellent for grip, also introduce more rolling resistance than standard street tires, subtly affecting fuel economy. Carrying heavy cargo, mounting a roof rack with gear, or experiencing strong headwinds on the highway will also contribute to a slight decrease in efficiency. Conversely, careful, conservative highway driving with minimal elevation changes might even see drivers nudge closer to, or occasionally exceed, the 28 MPG highway rating. The buyer understands that the Forester Wilderness is a tool for a specific job, and its fuel economy will fluctuate based on how enthusiastically that tool is employed.

How it compares

When placed alongside its direct competitors, the 2025 Subaru Forester Wilderness has a 26 MPG combined rating. The Toyota RAV4 TRD Off-Road, another popular choice for adventure seekers, with its 2.5L 4-cylinder engine and AWD, also achieves 28 MPG combined. While slightly higher, the RAV4 TRD Off-Road doesn’t quite match the ground clearance or the specific off-road tuning of the Forester Wilderness. The Honda CR-V Sport Touring Hybrid AWD, by virtue of its hybrid powertrain, delivers a far superior 37 MPG combined. However, the CR-V Hybrid, while capable, doesn’t offer the same level of ruggedness, underbody protection, or approach/departure angles as the Forester Wilderness. Its focus is more on refined on-road manners with occasional mild off-road capability. For those seeking even more ruggedness, the unibody Jeep Cherokee Trailhawk, with its 2.0L turbo or 3.2L V6, offers significantly lower fuel economy, often in the low 20s MPG combined, emphasizing its more hardcore off-road focus at the expense of everyday efficiency. The FORESTER MPG across all years has consistently maintained a practical balance, and the Wilderness trim continues this tradition by offering genuine trail capability without resorting to the dismal fuel numbers often associated with dedicated off-roaders. The buyer who opts for a Forester Wilderness is specifically choosing a vehicle that splits the difference effectively: reliable enough for true adventure, yet efficient enough for daily life, outperforming most directly comparable, trail-ready non-hybrid SUVs, and for more on all Subaru fuel economy data, our full database provides specific insights.

Tips to maximize efficiency

To optimize fuel economy in the 2025 Forester Wilderness, drivers should maintain consistent throttle input, especially on the highway. The CVT is engineered to find the most efficient gear ratio, and abrupt acceleration or deceleration forces it to constantly adjust, which burns more fuel. Gentle, progressive inputs will allow the transmission to settle into its most economical operating range.

Regular maintenance is critical for this vehicle’s longevity and efficiency. Keep the tires properly inflated to the manufacturer’s recommended pressure, as underinflated tires significantly increase rolling resistance. Adhere to the recommended service intervals for oil changes and air filter replacements, ensuring the 2.5L Boxer engine can breathe and perform optimally.

Be mindful of extra weight and aerodynamic drag. While roof rails are perfect for adventure gear, remove roof racks, cargo boxes, or unused bike carriers when not needed. These accessories can create significant wind resistance, especially at highway speeds, noticeably reducing fuel efficiency.

Use the vehicle’s X-MODE only when necessary for challenging terrain. While invaluable for off-roading, X-MODE adjusts throttle response and transmission mapping to maximize traction and control, not fuel economy. On paved roads or light gravel, keep it disengaged to maintain standard, more efficient driving dynamics.

Plan your routes to avoid unnecessary idling and stop-and-go traffic. Extended idling consumes fuel without covering any distance, and constant braking and accelerating in heavy traffic are detrimental to overall efficiency. Use navigation apps to find the least congested paths whenever possible.
