Fuel Efficiency Across the Subaru Lineup
When it comes to buying a new car, fuel efficiency is definitely a top priority for many people. Subaru has a great lineup that strikes a nice balance between capability and good mileage. Whether you need a compact car for city driving, a versatile SUV for family adventures, or even an all-electric option, Subaru has something that can help you save on gas while still giving you that reliable performance you want on the road.
If you’ve been researching Subaru Legacy MPG, you’ll find that the Legacy remains one of the brand’s most fuel-efficient gas-powered sedans. Although the Legacy was discontinued after the 2025 model year, its impressive EPA-estimated fuel economy continues to make it a popular benchmark among Subaru models. Alongside the Legacy, vehicles like the Crosstrek, Forester, Outback, Impreza, Ascent, and Solterra each offer their own blend of efficiency, performance, and practicality.
Which Subaru Models Offer the Best Fuel Efficiency?
The Subaru lineup includes efficient sedans, capable SUVs, performance models, and an all-electric SUV. Fuel economy varies by vehicle size, engine, and intended purpose, giving drivers plenty of choices based on their lifestyle.
*Based on the latest available EPA estimates.
Among Subaru’s gasoline-powered models, the Subaru Legacy MPG ratings remain among the highest, reaching an EPA-estimated 27 MPG in the city and 35 MPG on the highway. Drivers looking to eliminate fuel consumption entirely can opt for the all-electric Solterra, while those prioritizing performance may prefer the BRZ or WRX.
How Do the Crosstrek, Forester, and Outback Compare?
Subaru’s SUV lineup is known for combining standard Symmetrical All-Wheel Drive with competitive fuel economy.
The 2026 Crosstrek earns up to 26 city and 33 highway MPG, making it an excellent choice for commuters and drivers who want a compact crossover that’s easy to maneuver while remaining fuel efficient.
The 2026 Forester delivers the same EPA estimates of 26 city and 33 highway MPG, but offers additional cargo space and a more spacious cabin for families or drivers who frequently haul gear.
The 2026 Outback offers up to 25 city and 31 highway MPG. While it gives up a small amount of fuel economy compared to the Crosstrek and Forester, it rewards drivers with greater passenger comfort, cargo capacity, and long-distance touring capability.
Which Subaru Sedans and Performance Models Deliver the Best Fuel Economy?
For drivers who prioritize efficiency, Subaru’s sedan lineup continues to stand out.
The 2025 Subaru Legacy MPG ratings remain impressive, reaching up to 27 MPG city and 35 MPG highway. Combined with standard Symmetrical All-Wheel Drive and a spacious interior, the Legacy offered an ideal balance between comfort, confidence, and fuel savings.
The 2026 Subaru Impreza follows closely with an EPA-estimated 27 city and 33 highway MPG, making it a practical choice for everyday commuting and city driving.
Drivers looking for a more engaging driving experience can consider the Subaru BRZ and Subaru WRX. The BRZ delivers 20 city and 27 highway MPG, while the turbocharged WRX achieves 19 city and 26 highway MPG. Although these models prioritize performance over efficiency, they still provide respectable fuel economy within the sports car segment.
How Fuel Efficient Is the Subaru Ascent?
As the largest SUV in Subaru’s lineup, the Ascent naturally consumes more fuel than smaller models, but it remains competitive among three-row SUVs.
The 2026 Subaru Ascent is EPA-estimated at 19 MPG in the city and 26 MPG on the highway. Its spacious interior, seating for up to eight passengers, generous cargo capacity, and standard all-wheel drive make it a practical choice for families who need additional room without moving into a full-size SUV.
Why Consider the Subaru Solterra?
The Subaru Solterra represents a different approach to efficiency by eliminating gasoline altogether.
As Subaru’s all-electric SUV, the Solterra achieves an EPA-estimated 131 city and 109 highway MPGe, making it the most energy-efficient vehicle in the lineup. Along with standard all-wheel drive, instant electric torque, and quiet operation, it offers drivers an environmentally friendly alternative while maintaining the capability expected from a Subaru.
How Can Drivers Maximize Fuel Economy?
Regardless of which Subaru model you drive, everyday habits and routine maintenance can make a noticeable difference in real-world fuel economy.
Simple ways to maximize efficiency include:
- Keep tires properly inflated.
- Stay current with scheduled maintenance.
- Replace engine air filters when recommended.
- Remove unnecessary cargo to reduce vehicle weight.
- Take off roof racks when they aren’t needed.
- Accelerate and brake smoothly.
- Maintain consistent highway speeds whenever possible.
- Avoid excessive idling.
While EPA estimates provide a useful benchmark, real-world fuel economy depends on driving conditions, weather, terrain, and driving style. By combining efficient driving habits with regular maintenance, drivers can help maximize the fuel efficiency of any Subaru model, from the fuel-sipping Subaru Legacy and Impreza to adventure-ready SUVs like the Forester and Outback or the all-electric Solterra.
