30 MPG combined is not the main reason someone buys a 2021 Subaru Impreza Sport 5-Door 2.0L. This vehicle is chosen for its standard all-wheel drive, practical hatchback configuration, and reputation for longevity. The fuel economy is simply acceptable, a compromise made for the benefits it provides in regions where snow and inclement weather are common. It’s a reliable workhorse of a compact with a character all its own.

City and highway performance

The EPA estimates of 27 MPG in the city and 35 MPG on the highway give a better indication of the Impreza Sport’s efficiency depending on your driving style. City driving, with its stop-and-go nature, highlights the engine’s responsiveness, while highway cruising showcases its ability to maintain respectable fuel economy at higher speeds. The automatic transmission (AV-S7), a continuously variable unit, is programmed to mimic the feel of a conventional automatic, preventing the droning sensation that sometimes plagues CVTs. This helps make both city and highway driving more engaging for the driver.

Annual fuel cost

The EPA’s annual fuel cost estimate for the 2021 Subaru Impreza Sport 5-Door is $1,450. This figure is based on driving 15,000 miles per year, using fuel prices at the national average. This cost will fluctuate based on current fuel prices and individual driving habits, but provides a reasonable benchmark for potential owners. Keep in mind if your driving is predominantly city or highway, you can adjust the MPG numbers accordingly to arrive at a more accurate estimate for your specific situation.

Real-world expectations

While the EPA provides standardized testing, real-world fuel economy always varies. Factors like traffic conditions, weather, driving style, and even tire pressure can impact the MPG you actually achieve. The Impreza’s all-wheel-drive system, while a major selling point, also adds weight and drivetrain friction to the equation, which can slightly reduce fuel efficiency. Owners who prioritize smooth acceleration and consistent speeds will likely see results closer to the EPA estimates. More aggressive drivers may experience somewhat lower numbers.

How it compares

Compared to other compact hatchbacks with optional all-wheel drive, the Impreza’s fuel economy is competitive. The Mazda3 2.5 S with front-wheel drive achieves 28 MPG combined and 36 MPG highway, but opting for all-wheel drive lowers these figures somewhat. The Toyota Corolla Hatchback achieves 32 MPG combined in FWD form, making it a fuel-sipping option, but all-wheel drive isn’t available. The Honda Civic Hatchback, another popular choice, gets around 31 MPG combined, but also lacks the option of all-wheel drive. The Impreza’s unique offering of standard all-wheel drive makes it a distinct choice for buyers who want that feature without sacrificing too much in fuel economy.

Tips to maximize efficiency

The 2.0L engine in the Impreza responds well to smooth acceleration. Avoid aggressive starts and stops, and try to maintain a consistent speed whenever possible. Anticipate traffic flow and coast when approaching red lights or slowing traffic as much as possible.

Regular maintenance is critical for any car, but especially one with all-wheel drive. Ensure that scheduled maintenance items are completed according to the manufacturer’s recommendations. This includes oil changes, air filter replacements, and tire rotations, which all play a role in optimizing fuel efficiency.

Tire pressure significantly affects rolling resistance. Check your tire pressure regularly and maintain it at the recommended level. The correct tire pressure is typically listed on a sticker inside the driver’s side doorjamb. Properly inflated tires not only improve fuel economy but also contribute to better handling and tire life.

Avoid carrying unnecessary weight in the vehicle. Extra cargo adds load to the engine, reducing fuel efficiency. Remove any items from the trunk that are not essential. Similarly, if you use a roof rack, remove it when not in use, as it increases aerodynamic drag and reduces MPG.
