26 MPG combined is a respectable figure for the 2021 Subaru Outback AWD 2.4L, although it’s not going to win any hypermiling contests. This number reflects a balance between the demands of all-wheel drive, a strong engine, and the Outback’s goal: providing sure-footed, all-weather transport for active individuals and families who prioritize capability and reliability over outright fuel efficiency. This isn’t a vehicle primarily purchased for its low running costs; it’s bought for what it enables: access to remote trails, confident handling in snow, and the security of knowing it’ll likely start on the coldest mornings. Fuel economy is a consideration, but rarely the defining factor.

City and highway performance

The EPA estimates the 2021 Subaru Outback 2.4L at 23 MPG in the city and 30 MPG on the highway. The city figure is respectable, given the inherently less-efficient stop-and-go nature of urban driving, where the Outback’s all-wheel-drive system is constantly engaged, adding weight and friction. The 30 MPG highway rating is where the Outback performs well, indicating that on long cruises, its engine and transmission can operate more efficiently, allowing for comfortable and relatively economical journeys. Owners should understand that aggressive acceleration and high speeds will significantly reduce these numbers, while a gentle, steady hand on the throttle will help achieve results closer to the EPA estimates.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2021 Subaru Outback AWD 2.4L to be $1,700. This figure is based on driving 15,000 miles per year, using fuel prices based on national averages. Keep in mind that this number is just an estimate and your actual fuel costs will vary depending on your driving habits, the type of fuel you use, and prevailing fuel prices in your area. If you consistently drive more aggressively than average, or if fuel prices are significantly higher in your region, you can expect your annual fuel costs to be higher than $1,700.

Real-world expectations

Experienced Outback owners know that achieving the EPA’s ratings requires conscious effort. Most drivers will see figures slightly below the official numbers in everyday driving. Variables like tire pressure, roof racks (a common Outback accessory), and cargo weight all impact fuel consumption. and the Outback’s all-wheel-drive system, while invaluable in inclement weather, adds a layer of loss that affects overall efficiency. Therefore, a realistic expectation for combined MPG sits in the low-to-mid 20s for most owners, especially those living in hilly areas or regularly carrying passengers and gear.

How it compares

Compared to its rivals, the 2021 Subaru Outback 2.4L sits mid-pack in terms of fuel economy. The Toyota RAV4 AWD, for instance, achieves 28 MPG combined, making it a slightly more efficient choice. The Honda CR-V AWD gets 29 MPG combined. However, these vehicles don’t offer the same level of standard all-wheel-drive capability and rugged character as the Outback. The Nissan Rogue AWD nets 27 MPG combined, a marginal improvement over the Subaru. For those prioritizing cargo capacity and adventurous spirit above all else, the Outback’s trade-off in fuel economy will often be considered acceptable. You can look at all Subaru fuel economy data.

Tips to maximize efficiency

Gentle acceleration is key to achieving optimal fuel economy in the Outback. Avoid aggressive starts and hard braking. The Outback’s automatic transmission is designed to shift smoothly and efficiently, but only if driven with moderation. Use a light foot on the accelerator to allow the transmission to upshift early, keeping the engine in its most efficient operating range.

Tire pressure is important for fuel efficiency. Regularly check your tire pressure and ensure that your tires are inflated to the recommended pressure specified on the driver’s side doorjamb. Underinflated tires increase rolling resistance, which reduces fuel economy, while also causing premature tire wear. A simple tire pressure gauge can be a valuable tool.

Reduce unnecessary weight. The heavier the load, the more fuel the Outback needs to burn. Remove any unnecessary items from the vehicle, especially from the cargo area. Roof racks can also negatively impact fuel economy due to increased aerodynamic drag. If you are not using the roof rack, consider removing it to improve fuel efficiency.

Plan your trips strategically. Combine errands into a single trip to minimize cold starts. Cold starts consume significantly more fuel than warm starts. Route planning can also help avoid congested areas and reduce the amount of stop-and-go driving, which will improve fuel economy.
