31 MPG combined is a reasonable figure for the 2020 Subaru Impreza 5-Door 2.0L. It’s not going to win any hypermiling contests, but it’s a respectable return for a compact hatchback that comes standard with all-wheel drive. This is the core of the Impreza’s appeal: affordable practicality and year-round surefootedness. It’s a car for people who prioritize capability over outright fuel efficiency, but still need a budget-friendly daily driver.

City and highway performance

The EPA estimates for the 2020 Impreza 5-Door are 28 MPG in the city and 36 MPG on the highway. The city figure demonstrates the inherent disadvantage of Subaru’s symmetrical all-wheel drive; it requires more energy to turn all four wheels than a comparable front-wheel drive car. The highway number, however, is more competitive. The automatic transmission (Subaru calls it AV-S7) does a decent job of keeping the engine in its sweet spot at cruising speeds, and the relatively light weight of the Impreza helps to minimize wind resistance. Drivers who frequently undertake longer commutes should find the highway figure to be a pleasant surprise, offsetting some of the city fuel consumption.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2020 Subaru Impreza 5-Door 2.0L is $1,400. This figure is calculated based on driving 15,000 miles per year, using a national average fuel price. Individual fuel costs may vary depending on driving habits, local fuel prices, and the type of fuel used. However, $1,400 provides a useful benchmark for comparing the Impreza to other vehicles. While not the absolute lowest fuel cost in its class, it remains a competitive figure considering the standard all-wheel drive.

Real-world expectations

While EPA estimates provide a good starting point, real-world fuel economy can vary significantly. Aggressive driving, frequent short trips, and carrying heavy loads will all negatively impact fuel consumption. Smooth acceleration, consistent speeds, and proper tire inflation can help to maximize MPG. Owners report achieving figures close to the EPA estimates, particularly on longer journeys. However, city dwellers with stop-and-go commutes should expect to see numbers closer to the 28 MPG mark. Monitoring fuel consumption over time and adjusting driving habits accordingly can help Impreza owners optimize their fuel efficiency.

How it compares

The Impreza’s closest competitors include the Mazda3, Honda Civic Hatchback, and Toyota Corolla Hatchback. The Mazda3, particularly with the Skyactiv-G 2.5L engine, offers a sportier driving experience but achieves around 28 MPG combined with all-wheel drive. A front-wheel-drive Mazda3 can get up to 36 MPG combined. The Honda Civic Hatchback with the 1.5L turbo engine achieves approximately 35 MPG combined, making it a more fuel-efficient choice, but it lacks the all-weather capability of the Impreza. The Toyota Corolla Hatchback, rated at 35 MPG combined, is similarly efficient. For those prioritizing fuel economy, the Corolla and Civic are tempting, but they don’t offer the standard all-wheel drive system that is a major draw for Impreza buyers. The fact that Subaru still offers a manual transmission in the Impreza makes it a choice for drivers who value engagement, but the fuel economy suffers slightly compared to the automatic.

Tips to maximize efficiency

The 2.0L engine in the Impreza responds well to smooth and deliberate acceleration. Avoid sudden bursts of speed, especially from a standstill, as this burns fuel unnecessarily. Instead, gently ease onto the throttle and allow the engine to build momentum gradually. Consistent and predictable driving is beneficial to the longevity of the engine and the fuel economy overall.

Regular maintenance is key to maintaining optimal fuel economy. Ensure that the engine is properly tuned, the air filter is clean, and the tires are inflated to the recommended pressure. A well-maintained engine runs more efficiently, and properly inflated tires reduce rolling resistance. Review all Subaru fuel economy data to compare past maintenance data.

The Impreza’s all-wheel drive system provides enhanced traction and stability, but it also adds weight and complexity, which can impact fuel economy. During periods of dry weather and good road conditions, consider using a more fuel-efficient driving mode if your model is equipped with one. If not, simply be mindful of your driving habits and avoid unnecessary aggressive maneuvers that engage the all-wheel drive system more frequently.

Minimize the use of accessories that draw power from the engine, such as air conditioning and defrosters. These systems place an extra load on the engine, which can reduce fuel economy, particularly during city driving. When possible, opt for natural ventilation or use recirculated air to reduce the strain on the air conditioning system.
