31 MPG combined might not sound groundbreaking, but consider the 2017 Subaru Impreza 5-Door 2.0L 4-cyl. This isn’t a hybrid, a downsized turbo, or an econobox. It’s a practical, all-wheel-drive hatchback, and that fuel economy figure is a significant part of its appeal for those who value capability and year-round confidence without spending a lot on gas.

City and highway performance

The EPA estimates the 2017 Impreza 5-Door at 28 MPG in the city and 37 MPG on the highway. These numbers reflect the realities of its 2.0L four-cylinder engine paired with the automatic (AV-S7) continuously variable transmission (CVT). The city figure demonstrates respectable stop-and-go efficiency, aided by the CVT’s ability to keep the engine in its most efficient range. On the highway, the Impreza shines, achieving a genuinely commendable MPG rating that makes it a practical choice for commuters and road-trippers alike. Remember, these numbers are achieved with all-wheel drive constantly engaged, a feature that directly impacts fuel consumption.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2017 Subaru Impreza 5-Door 2.0L 4-cyl at $1,400. This figure is based on driving 15,000 miles per year and using national average fuel prices. It’s a benchmark designed to provide a standard for comparison against other vehicles. For Impreza buyers, especially those who live in areas with inclement weather requiring all-wheel drive, this relatively low annual fuel cost is a key consideration. It’s a balance between practicality, safety, and affordability.

Real-world expectations

While the EPA numbers are a useful guide, real-world fuel economy always varies depending on driving habits, road conditions, and maintenance. Impreza owners who spend most of their time in stop-and-go city traffic may see figures closer to the EPA’s 28 MPG city rating, or even slightly lower. Drivers who primarily travel on the highway, maintain a steady speed, and practice efficient driving techniques could realistically achieve or even exceed the 37 MPG highway figure. Regular maintenance, including tire inflation and oil changes, also plays a vital role in maintaining optimal fuel efficiency. Aggressive driving, frequent hard acceleration, and carrying excessive weight in the vehicle will all negatively impact fuel economy.

How it compares

The 2017 Impreza’s fuel economy is competitive within its segment, especially considering its standard all-wheel drive. The Honda Civic Hatchback, in its front-wheel-drive configuration, offers an EPA-estimated 34 MPG combined with its CVT, giving it a slight edge. Likewise, a Toyota Corolla Hatchback (formerly known as the Scion iM) can achieve around 32 MPG combined. But those vehicles lack the Impreza’s all-weather capability. The Mazda3 hatchback, known for its sporty driving dynamics, achieves around 31 MPG combined, similar to the Impreza. These comparisons are crucial for buyers who prioritize fuel efficiency alongside other factors like performance and practicality. For those considering other Subaru models, all Subaru fuel economy data is readily available.

Tips to maximize efficiency

Use the Impreza’s Eco mode, if equipped. This system adjusts throttle response and transmission mapping to prioritize fuel efficiency, particularly in city driving. The difference may be subtle, but over time, those small gains can add up. Eco mode is especially effective when cruising at consistent speeds.

Pay close attention to tire pressure. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressure regularly and inflate them to the pressure recommended on the door jamb sticker. Properly inflated tires also improve handling and tire life.

Avoid unnecessary idling. Modern engines are designed to restart quickly and efficiently, so there’s little benefit to idling for extended periods. If you’re stopped for more than a minute or two, turn off the engine. This simple habit can significantly reduce fuel consumption, especially in urban environments.

Use cruise control carefully on the highway. While cruise control can help maintain a steady speed and improve fuel economy on flat, open roads, it can decrease efficiency in hilly terrain. The system may downshift to maintain speed, burning more fuel than if you were to modulate the throttle yourself. Anticipate hills and adjust your speed accordingly.

Consider the weight inside the car. Hauling around unnecessary items in your trunk or backseat adds extra weight, which negatively impacts fuel economy. Remove any items you don’t need to carry regularly. Every extra 100 pounds reduces MPG.
