29 MPG combined makes the 2025 Subaru Impreza 2.5L 4-cyl an efficient and practical choice for buyers prioritizing all-weather capability and Subaru’s strong reliability in a compact package. This isn’t a vehicle chasing headline-grabbing performance or groundbreaking luxury, it’s a focused machine designed to deliver dependable, economical transportation with a strong emphasis on safety and everyday usability, all while maintaining a respectable fuel footprint.

City and highway performance

The EPA rates the 2025 Impreza 2.5L at 26 MPG in the city and 33 MPG on the highway. These numbers align with the vehicle’s character and mission. In urban environments, the 2.5-liter Boxer engine, paired with Subaru’s Lineartronic CVT (dubbed AV-S8), provides smooth, accessible power with admirable restraint. Stop-and-go traffic, common in city driving, doesn’t unduly punish the Impreza’s fuel economy, thanks to the CVT’s efficient operation and the engine’s torque delivery. You won’t find yourself constantly dipping deep into the throttle to keep up, which is critical for city efficiency.

On the open road, the 33 MPG highway figure is equally impressive for a standard all-wheel-drive vehicle. Subaru’s symmetrical all-wheel drive, a non-negotiable feature for most Impreza buyers, typically carries a slight fuel economy penalty compared to front-wheel-drive competitors. Yet, the Impreza manages to punch above its weight class, delivering highway cruising that won’t have you constantly scanning for the next fuel station. The CVT’s ability to keep the engine in its most efficient RPM range at highway speeds is a significant factor here, allowing for relaxed and economical long-distance travel. This combination of city and highway efficiency is exactly what the Impreza buyer expects: a vehicle that performs admirably in diverse driving conditions without becoming a drain on their wallet.

Annual fuel cost

The EPA estimates an annual fuel cost of $1,500 for the 2025 Subaru Impreza 2.5L 4-cyl. This figure is based on driving 15,000 miles per year, with an approximate 55% city and 45% highway driving split, using national average fuel prices. It’s a pragmatic projection that provides real-world context for potential owners. For a vehicle with standard all-wheel drive, excellent safety ratings, and the inherent durability Subaru is known for, this annual fuel expenditure delivers good value. Buyers of the Impreza aren’t typically looking for the absolute cheapest car to run, but they are astute enough to recognize that reliability and capability often come with a slightly higher initial cost and a desire for predictable, reasonable running costs. The $1,500 annual fuel cost fits perfectly within their expectation of a practical, no-nonsense daily driver that won’t surprise them with exorbitant operating expenses.

Real-world expectations

In real-world driving conditions, the 2025 Impreza 2.5L generally meets or even slightly exceeds its EPA estimates for many drivers. Subaru’s Boxer engines, particularly when paired with the Lineartronic CVT, have a well-earned reputation for consistent fuel efficiency. Drivers who maintain a steady foot, anticipate traffic, and take advantage of the CVT’s smooth power delivery will likely see numbers very close to the 29 MPG combined. Those with a heavy right foot, frequent short trips, or consistently battling severe winter conditions (where AWD is constantly engaged) might see a slight dip. However, the inherent efficiency of the powertrain means that even under less-than-ideal circumstances, the Impreza remains competitive. This isn’t a vehicle that suffers from a massive gap between its EPA sticker and actual performance, it delivers reliably.

The buyer for the Impreza is typically an individual or a small family living in areas with varied weather, valuing safety, residual value, and the confidence that all-wheel drive provides. They understand that while a dedicated FWD economy car might shave a few MPGs, the trade-off in all-weather capability and Subaru’s reliable build quality isn’t worth it. For them, 29 MPG combined is an excellent return on investment for a vehicle that truly inspires confidence in any condition. They accept this fuel economy not as a compromise, but as a balanced outcome for a vehicle that excels in its specific mission, a clear differentiator from other compact cars that might offer slightly better pure MPG but lack the Impreza’s inherent attributes.

How it compares

When placed against its competitive set, the 2025 Subaru Impreza 2.5L’s 29 MPG combined is a strong showing, especially considering its standard all-wheel drive. A direct front-wheel-drive competitor like the Honda Civic Sedan with the 2.0L engine achieves an impressive 33 MPG combined, while the turbocharged 1.5T hits 36 MPG combined (EX/Touring trims). The Toyota Corolla LE FWD, equipped with its 2.0L Dynamic Force engine, also stands out with 35 MPG combined. These front-wheel-drive vehicles undeniably hold an advantage in pure MPG. However, the crucial distinction lies in the Impreza’s standard symmetrical all-wheel drive, a feature either unavailable or optional and costly on these competitors.

For a more direct comparison amongst AWD-equipped compacts, the Mazda3 2.5 S Carbon Edition AWD comes in at 30 MPG combined, a very close competitor, but often at a higher price point for similar trim levels. When you consider the cost of adding all-wheel drive to something like a Toyota Corolla or Honda Civic (which often means stepping up to a more expensive, larger vehicle or an entirely different class), the Impreza’s value with standard AWD and 29 MPG becomes evident. Buyers are not cross-shopping the Impreza against the most efficient FWD compacts strictly on MPG, they are weighing the total package: AWD capability, safety, reliability, and then the fuel economy. The Impreza delivers an admirable balance, offering excellent day-to-day efficiency without sacrificing the all-weather confidence its buyers demand.

Tips to maximize efficiency

Maintaining proper tire pressure is one of the easiest and most impactful ways to ensure your Impreza delivers optimal fuel economy. Check your tire pressure regularly, at least once a month, and ensure they are inflated to the manufacturer’s recommended specifications found on the driver’s side door jamb placard. Underinflated tires increase rolling resistance, forcing the engine to work harder and consuming more fuel.

Adopt smooth driving habits, focusing on gradual acceleration and deceleration. The Impreza’s Lineartronic CVT is designed for efficiency, and it rewards drivers who avoid sudden bursts of speed or aggressive braking. Anticipate traffic and coast to stops when safe, allowing the transmission to keep the engine in its most efficient operating range.

Perform regular maintenance according to Subaru’s recommended schedule. Keeping the engine oil clean, air filters clear, and spark plugs in good condition ensures your 2.5L Boxer engine runs as efficiently as possible. A well-maintained engine burns fuel more completely and effectively, directly translating to better MPG and longevity for your vehicle.

Reduce unnecessary weight in the vehicle. While the Impreza isn’t a heavy vehicle to begin with, carrying weighty items or leaving roof racks on when not in use can incrementally diminish fuel economy. Every extra pound the engine has to move requires more energy, so a lighter load means more miles per gallon.

Use the Impreza’s Cruise Control feature on highway drives when traffic conditions allow. Maintaining a consistent speed minimizes unnecessary acceleration and deceleration, which are significant fuel consumer. This helps the CVT optimize gearing for sustained efficiency over longer distances. For more information on Subaru vehicles and their fuel efficiency, consider checking all Subaru fuel economy data.
