With 29 MPG combined, the 2020 Subaru Outback 2.5L is acceptably efficient for a mid-size wagon with standard all-wheel drive. People don’t buy this vehicle primarily to save fuel, but for its practicality, off-pavement capability, and all-weather security. Buyers prioritize those attributes, considering fuel economy a necessary compromise.

City and highway performance

The EPA estimates 26 MPG in the city and 33 MPG on the highway. The city figure reflects the efficiency limitations of a naturally aspirated engine together with the weight and driveline drag of a full-time AWD system. Stop-and-go traffic will invariably lower the average. On the open road, however, the Outback’s automatic transmission (AV-S8) allows the engine to cruise at lower RPMs, resulting in a more respectable highway rating. The powertrain is calibrated for consistent, predictable performance, rather than outright fuel-sipping.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2020 Subaru Outback 2.5L at $1,500. This is based on driving 15,000 miles per year, using national average fuel prices. It’s a useful comparison point, but individual expenses depend greatly on driving habits and local fuel costs. Someone who primarily drives short distances in the city will likely exceed this estimate, while someone who undertakes frequent highway trips might undercut it.

Real-world expectations

While the EPA provides a standardized yardstick, real-world MPG often deviates. Many Outback owners report numbers close to the official figures. Factors like tire pressure, roof racks, and driving style can significantly impact fuel consumption. Aggressive acceleration, frequent hard braking, and sustained high speeds will all diminish fuel economy.

Gentle driving, consistent speeds, and proactive maintenance can help achieve numbers closer to the EPA’s estimates. The Outback’s all-wheel drive system, while invaluable in adverse conditions, constantly distributes power, adding to drivetrain friction and reducing ultimate efficiency.

How it compares

The Outback’s 29 MPG combined rating positions it competitively within its niche. The Honda CR-V AWD, a popular compact SUV, achieves around 29 MPG combined. The Toyota RAV4 AWD delivers similar figures, hovering in the low 30s for combined MPG.

The Outback often differs in its body style. As a wagon (though Subaru markets it as an SUV), it trades some cargo volume for a lower roof and a more car-like driving experience. A similarly sized SUV often carries a slight MPG penalty. Those seeking the best fuel efficiency might consider a hybrid variant of the RAV4 or CR-V, boasting significantly higher MPG numbers, but sacrificing some of the Outback’s rugged appeal.

Tips to maximize efficiency

Given the Outback’s AWD system, maintaining proper tire inflation is critical. Underinflated tires increase rolling resistance. Consult the sticker on the driver’s side doorjamb for the recommended tire pressure, and check it regularly.

Avoid unnecessary weight. Carrying extra cargo in the trunk or on the roof rack increases fuel consumption. Remove items when not needed to lighten the load and reduce aerodynamic drag.

Anticipate traffic flow. Smooth acceleration and braking are far more efficient than rapid starts and stops. By looking ahead and anticipating changes in traffic, you can maintain momentum and reduce fuel-wasting maneuvers.

Use cruise control judiciously. On flat highway stretches, cruise control can help maintain a constant speed, improving fuel efficiency. However, in hilly terrain, it may downshift more frequently, negating any potential fuel savings. Adapt cruise control use to the driving conditions.

Consider using a lighter weight oil when possible and safe to do so. If you are getting your oil changed at the dealership ask about their recommended oil. Some manufacturers have seen a boost in MPG ratings during testing by moving to a lighter weight oil, which still provides adequate protection.
