32 MPG combined is a respectable figure for the 2023 Subaru Impreza 4-Door 2.0L. It’s not going to win any hypermiling competitions, but it’s a meaningful number for the practical, value-oriented folks who buy this car and need reliable all-weather transportation. These buyers prioritize affordability, longevity, and sure-footedness over outright fuel efficiency, and the Impreza delivers on all fronts, with reasonable fuel costs being part of the package.

City and highway performance

The EPA estimates of 28 MPG in the city and 36 MPG on the highway provide a more granular view of the Impreza’s fuel consumption. The city MPG reflects the extra effort required to repeatedly accelerate the 2.0L engine from a stop, a common scenario for urban commuters. The highway number highlights the efficiency of the continuously variable transmission (CVT) at steady speeds. The CVT, branded AV-S7 by Subaru, allows the engine to operate at its most efficient RPM range, maximizing fuel economy during long highway drives. Keep in mind that these numbers are achieved in ideal conditions; aggressive driving or heavy loads will naturally reduce them.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 Subaru Impreza 4-Door 2.0L at $1,350. This calculation is based on driving 15,000 miles per year and using national average fuel prices. While this provides a useful benchmark, your actual fuel costs will vary depending on your driving habits, the type of roads you frequent, and the prevailing fuel prices in your area. For example, someone who drives predominantly on the highway will likely see a lower annual fuel cost than someone who mainly drives in stop-and-go city traffic. However, $1,350 represents a solid, predictable figure that reflects the overall efficiency of the Impreza.

Real-world expectations

EPA estimates are a useful guide, but real-world MPG often varies. Expect anywhere from 28-38 MPG in mixed driving conditions, depending on your driving style and environment. Hard acceleration, frequent braking, and carrying heavy loads will all negatively impact fuel economy. Driving conservatively, anticipating traffic, and maintaining proper tire inflation can help you achieve or even exceed the EPA estimates. The Impreza’s all-wheel drive system adds some weight and drivetrain losses, which inevitably affect fuel consumption, especially during spirited driving, while it provides enhanced traction.

How it compares

The Impreza’s fuel economy positions it competitively within its class. The front-wheel drive Toyota Corolla LE, for example, boasts 35 MPG combined, making it a slightly more efficient choice for those who don’t need all-wheel drive. On the other hand, the Mazda3 with its standard engine achieves around 31 MPG combined, a touch below the Impreza. The Nissan Sentra SV gets around 33 MPG combined. The key differentiator for the Impreza buyer is the added security and capability of standard all-wheel drive, a feature often absent or optional on competitors. For those needing all-weather traction without the bulk of an SUV, the Impreza represents a compromise between fuel efficiency and year-round practicality.

Tips to maximize efficiency

Avoid aggressive acceleration and braking. The Impreza’s 2.0L engine responds well to smooth, deliberate inputs. Instead of flooring the accelerator, gradually increase your speed, and anticipate traffic flow to minimize hard braking. This will improve your fuel economy and extend the life of your brakes.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressure regularly, ideally every two weeks, and inflate them to the recommended pressure listed on the driver’s side door jamb. Even a few PSI can make a noticeable difference.

Reduce aerodynamic drag. Remove any unnecessary items from the roof rack, as these create drag and reduce fuel economy, especially at highway speeds. Consider removing the roof rack entirely if you don’t use it frequently. Avoid driving with the windows down at highway speeds, as this also increases drag.

Plan your trips strategically. Combine multiple errands into a single trip to minimize cold starts. The engine is most inefficient when it’s cold, so reducing the number of cold starts will save fuel. Consider using route planning apps to avoid traffic congestion, which can significantly reduce fuel economy.

Use cruise control wisely. On long, flat stretches of highway, cruise control can help maintain a consistent speed, optimizing fuel efficiency. Avoid using cruise control in hilly terrain, as it can cause the transmission to constantly shift gears, negating its efficiency benefits. In such cases, manually modulating the throttle may be more efficient.
