Fuel economy at a glance

These are the EPA's official ratings for the 2025 Subaru Solterra AWD. The numbers come from a standardised laboratory test cycle and are the same figures that appear on the window sticker of every new car. Real-world mileage varies with driving style, weather, fuel quality, and how heavily loaded the car is.

Combined MPG is a 55/45 weighted blend of the city and highway test cycles. The EPA uses it as the single number you can compare across the entire dataset, including hybrids and EVs (which use the equivalent MPGe figure).

How the 2025 Subaru Solterra AWD compares

The 2025 Subaru Solterra AWD returns 104 combined MPG. Cars in the Small Sport Utility Vehicle 4WD class for the same model year average 43.4 MPG, which puts this car ahead of the class average by about 140%.

The most efficient car in the Small Sport Utility Vehicle 4WD class for the 2025 model year is the Tesla Model Y Long Range AWD at 117 MPG. The bar chart below puts the Subaru Solterra AWD alongside the class best and the class average so you can see the full picture.

For broader context, the average new car of the 2025 model year (across all classes) returns 44.3 MPG. Larger vehicles pull the all-cars average down, so do not use that figure on its own to judge a small car or a hybrid. The full list of the most efficient cars of the 2025 model year is on its own page.

Annual fuel cost across driving patterns

The headline annual fuel cost the EPA publishes assumes 15,000 miles of driving per year and a fuel mix of 55% city and 45% highway. The dollar figure is calculated using the EPA's current reference price for electricity, which is $0.15/kilowatt-hour. EPA updates that reference periodically rather than tracking live pump prices, so treat it as a window-sticker estimate rather than today's pump number.

The table below scales the EPA's number to three common driving patterns. The combined MPGe and the reference electricity price stay constant, only the annual mileage changes. Charging at home rather than at a public DC fast charger usually lowers the real cost below the EPA's published figure.

Driving pattern Estimated annual fuel cost
Light driver, 7,500 miles per year $350
Average driver, 15,000 miles per year $700
Heavy driver, 25,000 miles per year $1,167

Year-over-year MPG for the Subaru Solterra AWD

The EPA has rated the Subaru Solterra AWD across 4 model years, from 2023 Subaru Solterra AWD through 2026 Subaru Solterra AWD. The numbers below are the best combined MPG figure the EPA published for each year, which lets you see when the car was at its most efficient and how recent generations stack up.

The 2023 Subaru Solterra AWD returned 104 MPG. The most recent 2026 Subaru Solterra AWD returns 120 MPG. That is an improvement of 16 MPG over 3 model years, the kind of gain that usually comes from smaller engines, hybrid systems, or aerodynamic redesigns.

Specifications

The 2025 Subaru Solterra AWD is a fully electric vehicle. It is powered by 80 and 80 kw ac synchronous. The EPA rates its driving range at 227 miles.

Engine, transmission, and drivetrain together drive most of the variation in fuel economy across trims. A larger engine moves the car with less effort but burns more fuel. A turbo lets a small engine punch above its weight, often without much MPG penalty. All-wheel drive adds traction and weight, and usually costs a couple of MPG compared with two-wheel drive of the same engine.

Common questions about the 2025 Subaru Solterra AWD

Quick answers to the questions people most often search for when looking up the 2025 Subaru Solterra AWD.

  • Is the 2025 Subaru Solterra AWD fuel efficient?
    Yes. The 2025 Subaru Solterra AWD returns 104 combined MPG, which beats the average car in the Small Sport Utility Vehicle 4WD class for the same model year by about 140%.
  • What MPG does the 2025 Subaru Solterra AWD get?
    The EPA rates the 2025 Subaru Solterra AWD at 104 combined MPG, 114 MPG in city driving, and 94 MPG on the highway. Real-world numbers depend on your driving style, the weather, and how loaded the car is.
  • How much does it cost to fuel a 2025 Subaru Solterra AWD per year?
    The EPA estimates an annual fuel cost of $700 for the 2025 Subaru Solterra AWD. That figure assumes 15,000 miles of driving per year, a 55% city and 45% highway split, and the EPA's published average fuel price for the rated fuel grade.
  • Does the 2025 Subaru Solterra AWD use gasoline?
    No. The 2025 Subaru Solterra AWD is fully electric and runs on grid electricity. The MPGe figure on this page converts electricity use into a gasoline-equivalent so you can compare it directly to a regular car.
  • Has the Subaru Solterra AWD become more fuel efficient over time?
    Yes. The first EPA-rated Subaru Solterra AWD, the 2023 Subaru Solterra AWD, returned 104 combined MPG. The most recent 2026 Subaru Solterra AWD returns 120 MPG, an improvement of 16 MPG over the run.
  • How much CO₂ does the 2025 Subaru Solterra AWD emit?
    The 2025 Subaru Solterra AWD produces zero tailpipe emissions because it runs entirely on electricity. The full carbon footprint of charging it depends on how the electricity on your local grid is generated, which varies a lot from one state to another.
  • What is the difference between the city and highway MPG of the 2025 Subaru Solterra AWD?
    City driving returns 114 MPG and highway driving returns 94 MPG. A flat (or city-better) split is the signature of a hybrid or electric drivetrain, where regenerative braking recovers energy that would otherwise be lost in stop-start city traffic.
  • What motor does the 2025 Subaru Solterra AWD use?
    The 2025 Subaru Solterra AWD uses 80 and 80 kW AC Synchronous. Electric motors do not have a displacement or cylinder count the way a combustion engine does, so EPA reporting focuses on the motor type and battery system instead.
  • What transmission and drivetrain does the 2025 Subaru Solterra AWD have?
    The 2025 Subaru Solterra AWD comes with a automatic (a1) transmission and all-wheel drive. All-wheel-drive variants typically read 1 to 3 MPG lower than the front-wheel-drive equivalent of the same engine, since the extra hardware adds weight and parasitic loss.
  • How does the 2025 Subaru Solterra AWD compare to the best car in its class?
    The most efficient car in the Small Sport Utility Vehicle 4WD class for the 2025 model year is the Tesla Model Y Long Range AWD at 117 combined MPG. The Subaru Solterra AWD returns 104 MPG, a gap of 13 MPG. If you are comparing on fuel economy alone, the class leader is worth a look.
