The 2020 Subaru Impreza 4-Door 2.0L gets 31 MPG combined, a solid number considering it’s a compact sedan with standard all-wheel drive. It prioritizes all-weather security and a comfortable ride, and good fuel economy is a plus.

City and highway performance

The EPA estimates around-town driving at 28 MPG. Stop-and-go traffic will likely lower that number, but the Impreza’s relatively lightweight construction helps maintain decent fuel economy in the city. The Impreza does better on the open road, achieving 36 MPG on the highway. The automatic transmission (AV-S7), a continuously variable unit, keeps engine speeds relatively low at cruising speeds, contributing to efficient highway performance. These figures are based on ideal driving conditions, so aggressive acceleration or consistently high speeds will negatively affect your mileage.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2020 Subaru Impreza 4-Door 2.0L at $1,400. This is based on driving 15,000 miles per year and assumes the driver pays the national average price for gasoline. Your individual experience will vary depending on your driving habits, the type of roads you drive on, and the price of fuel in your area, but $1,400 provides a useful point of reference.

Real-world expectations

The EPA provides a standardized benchmark, but real-world MPG can differ. Some owners report slightly lower figures, especially in areas with hilly terrain or frequent traffic congestion. If you drive conservatively and maintain your vehicle properly, you might see the EPA’s numbers. Driving style, tire pressure, and even the type of gasoline you use can all play a role. Some owners who prioritize fuel economy have reported exceeding the EPA estimates on long highway trips at consistent speeds.

How it compares

The Impreza’s fuel economy is respectable within its class, but the standard all-wheel drive requires a trade-off. A front-wheel-drive Toyota Corolla, for example, gets an EPA combined rating of 34 MPG in its LE trim. The Honda Civic sedan also offers a combined 33 MPG in its LX trim. Comparing all Subaru fuel economy data reveals that the Impreza’s efficiency is similar to other models. For buyers who want all-weather traction and standard AWD, the Impreza’s slightly lower MPG is often an acceptable compromise. For more details, check out IMPREZA MPG across all years.

Tips to maximize efficiency

Avoid aggressive acceleration. The Impreza 2.0L engine is designed for smooth, steady power delivery, not rapid bursts of speed. Frequently flooring the accelerator will quickly deplete your fuel tank without significantly improving your commute time.

Monitor your tire pressure regularly. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressure at least once a month and keep them inflated to the manufacturer’s recommended specifications.

Minimize unnecessary cargo. Carrying extra weight in your vehicle reduces fuel economy. Remove any unnecessary items from your trunk and back seat to lighten the load and improve your MPG.

Use cruise control on the highway. Maintaining a consistent speed helps optimize fuel consumption. Cruise control can prevent unintentional speed fluctuations, leading to better fuel efficiency on long highway drives.

Consider using a fuel additive designed to clean fuel injectors. Over time, deposits can build up in the fuel injectors, hindering their ability to spray fuel efficiently. A fuel additive can help remove these deposits and restore optimal performance.
