The 2024 Subaru Outback’s 25 MPG combined rating shows that owners accept that all-weather confidence and cargo capacity are more important than efficiency. This isn’t a vehicle for those wanting the best MPG. It’s for people who value capability, and accept middling fuel economy as part of the deal.

City and highway performance

The EPA estimates the 2024 Outback AWD 2.4L achieves 22 MPG in city driving and 29 MPG on the highway. The city figure reflects the penalty paid for the Outback’s standard all-wheel-drive system and the engine’s power when accelerating. The highway number is better, but still lags many front-wheel-drive competitors. The automatic transmission (AV-S8) helps on the highway by keeping the engine speed relatively low, but the Outback’s aerodynamic profile is more SUV than sleek wagon.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2024 Subaru Outback 2.4L is $1,750. This figure is based on driving 15,000 miles per year using national average fuel prices. Actual costs will vary depending on driving habits, local fuel prices, and city versus highway driving. However, this gives you a baseline for comparing the Outback’s running costs against other vehicles.

Real-world expectations

While the EPA figures are a good starting point, real-world MPG often differs. Outback owners report that achieving the 29 MPG highway figure requires conscious effort and maintaining speeds close to the limit. Aggressive acceleration, frequent short trips, and carrying heavy loads negatively impact fuel economy. However, careful drivers should be able to closely match the EPA’s combined figure in daily driving.

How it compares

Compared to other vehicles, the Outback’s fuel economy is in the middle. The Toyota RAV4 AWD achieves around 30 MPG combined, while the Honda CR-V AWD manages about 29 MPG. But both of these models lack the Outback’s standard all-wheel drive system across all trims. Even its own stablemate, the Subaru Forester, gets slightly better mileage at 29 MPG combined, mostly because of its smaller size and less powerful engine. People who don’t need the Outback’s ground clearance or spacious cargo area might find the Forester a more efficient choice. For Subaru fuel economy data, see all Subaru fuel economy data.

The related Outback Wilderness model, which has more off-road capability, has lower fuel economy at 23 MPG combined. The Jeep Grand Cherokee, another popular SUV with available four-wheel drive (though not standard AWD like the Outback), gets 22 MPG combined for its V6 engine. Buyers considering these options accept lower fuel numbers. If you’re trying to decide between model years, check the OUTBACK MPG across all years to verify your savings.

Tips to maximize efficiency

Gentle acceleration is key to maximizing fuel economy in the Outback. The 2.4L engine responds well to a light foot. Avoid flooring the accelerator unless needed and allow the automatic transmission to shift smoothly.

Tire pressure is important. Make sure your tires are inflated to the recommended pressure listed on the door jamb sticker. Underinflated tires increase rolling resistance, which reduces fuel economy. Check your tire pressure regularly, especially when the temperature changes. The tires equipped on your Outback from the factory may offer better rolling resistance than replacements, so consider using the same type and brand of tire when replacing them.

Reduce unnecessary weight. Carrying excessive cargo in the Outback adds to the load on the engine and reduces fuel economy. Remove unnecessary items from the trunk and backseat to minimize weight.

Plan your trips intelligently. Combine multiple errands into a single trip to minimize cold starts. A cold engine consumes more fuel than a warm one. Planning your route to avoid stop-and-go traffic can also improve fuel economy.

Avoid using accessories like air conditioning unless you need it. The AC compressor places a load on the engine, reducing fuel economy. Open the windows when possible, or use the ventilation system without engaging the AC.
