29 MPG combined is perfectly acceptable for the 2024 Subaru Impreza 2.5L, and it’s a number most buyers in this segment readily accept. This isn’t a hybrid chasing ultimate efficiency; it’s a reliable, strong hatchback that prioritizes all-weather capability and long-term durability. While there are more fuel-sipping compacts out there, few offer the Impreza’s standard all-wheel drive, a feature that remains a core selling point for those living in snowy or otherwise challenging climates. It’s a trade-off many are happy to make.

City and highway performance

The Impreza’s 2.5L engine, paired with its automatic transmission, reveals its split personality across different driving environments. The city rating of 26 MPG reflects the reality of stop-and-go traffic, where the all-wheel-drive system and the engine’s power demands inevitably take their toll. The engine isn’t straining, but efficiency isn’t its forte in this kind of driving. Out on the open road, however, the Impreza fares better. The 33 MPG highway figure is respectable, demonstrating that when cruising at a consistent speed, the engine can achieve better economy. Drivers who frequently commute long distances will appreciate this highway efficiency, which helps offset the lower city number. The automatic transmission chooses gears wisely enough once you’re up to speed, ensuring the engine isn’t working harder than it needs to.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2024 Subaru Impreza 2.5L at $1,500. This figure is based on driving 15,000 miles per year, with a mix of city and highway driving, and using the national average fuel price for regular unleaded gasoline. While individual fuel costs may vary depending on driving habits and local gas prices, this $1,500 estimation provides a solid baseline for budgeting. This number should be an important consideration for buyers who plan to put significant mileage on their Impreza.

Real-world expectations

While the EPA provides a standardized testing procedure, real-world fuel economy can fluctuate. Expect variations based on driving style, terrain, and weather conditions. Aggressive acceleration, frequent hard braking, and prolonged idling will all negatively impact fuel efficiency. Driving in hilly areas or in extreme cold also typically leads to lower MPG. However, drivers who adopt a gentler driving style and prioritize smooth acceleration can often come close to, or even exceed, the EPA estimates. Tire pressure maintenance is also important.

How it compares

The Subaru Impreza 2.5L competes in a crowded segment, and its fuel economy sits squarely in the middle of the pack. The Toyota Corolla Hatchback boasts a combined EPA rating of 35 MPG, making it a significantly more efficient choice. The Honda Civic Hatchback achieves 33 MPG combined, also surpassing the Impreza. However, neither of these options offers standard all-wheel drive, a feature that sets the Impreza apart, and is often worth the fuel economy penalty for dedicated Subaru owners. Even within the Subaru family, other options exist. Browsing all Subaru fuel economy data will reveal that the smaller Subaru Crosstrek offers slightly better MPG, but at the expense of overall cargo space. The Mazda3 offers similar fuel economy numbers to the Impreza, but with a more upscale interior and a sportier driving experience. The Impreza buyer isn’t necessarily seeking the absolute best MPG; rather, they prioritize the combination of all-wheel drive, practicality, and Subaru’s reputation for reliability, and they are willing to accept the fuel economy hit.

Tips to maximize efficiency

The most impactful thing you can do to save fuel in your Impreza is to adopt a smooth, gradual accelerating. Subaru’s all-wheel drive system loves to deliver power to the wheels and sip on gasoline. Avoid sudden bursts of speed, and instead ease into acceleration. Let the automatic transmission shift smoothly using less peak power.

Proper tire inflation is critical. Check your Impreza’s tire pressure regularly and inflate them to the recommended PSI, which can be found on a sticker inside the driver’s side doorjamb. Underinflated tires increase rolling resistance, which directly translates to reduced fuel economy. Staying on top of tire maintenance is a simple way to improve your MPG.

Reduce unnecessary weight inside the Impreza. Excess cargo adds to the vehicle’s overall weight, forcing the engine to work harder to maintain speed. Remove any unnecessary items from the trunk and rear seats to improve fuel efficiency. A lighter car is always a more efficient car.

Plan your routes strategically. Anticipate traffic flow and avoid congested areas whenever possible. Stop-and-go traffic significantly reduces fuel economy, so choosing routes with fewer stops and a more consistent speed can make a noticeable difference. A little pre-planning can pay off at the pump, especially in congested urban areas.
