30 MPG combined isn’t a fuel sipper, but it is for the 2015 Subaru Impreza Sport AWD 2.0L. This vehicle is bought as much for its all-weather capability as its practicality, a compact hatch that shrugs off snowstorms and gravel roads with equal aplomb. This Impreza isn’t chasing Prius-level efficiency; it’s chasing adventure, and a combined 30 MPG is the price of entry.

City and highway performance

The EPA estimates 27 MPG in the city and 35 MPG on the highway for this specific Impreza configuration. Those numbers reflect the realities of its 2.0-liter four-cylinder engine and continuously variable transmission (CVT). The city MPG acknowledges the inherent inefficiencies of stop-and-go driving, particularly with a full-time all-wheel-drive system adding mechanical drag. The 35 MPG highway rating shows the CVT’s ability to keep the engine at its most efficient RPM at cruising speed. But, don’t expect stellar acceleration when merging onto the interstate; this Impreza prioritizes fuel efficiency over outright speed.

Annual fuel cost

The EPA estimates an annual fuel cost of $1,450 for the 2015 Subaru Impreza Sport AWD 2.0L. This figure is based on driving 15,000 miles per year and using national average fuel prices when the data was compiled. Your actual fuel costs will vary depending on your individual driving habits, the type of driving you do (city versus highway), and changes in fuel prices in your area. Still, the $1,450 estimate provides a useful benchmark for comparing the Impreza’s fuel costs against other vehicles in its class. For those covering fewer than 15,000 miles annually, the cost will be proportionally lower.

Real-world expectations

EPA estimates are a good starting point, but real-world fuel economy often differs. Impreza owners frequently report seeing figures close to the EPA’s numbers, particularly on longer highway trips. However, aggressive driving, frequent short trips in cold weather, and carrying extra weight can all negatively impact fuel economy. Factor in the all-wheel-drive system constantly distributing power, and you’ll understand why some owners experience slightly lower numbers than the EPA rating. The 2015 Impreza Sport AWD delivers reasonable fuel economy for what it is.

How it compares

Compared to its competitors, the 2015 Subaru Impreza Sport AWD lands in the middle of the pack. A similarly equipped Mazda3 hatchback with a 2.0-liter engine achieves around 33 MPG combined, a slight but noticeable edge. The Toyota Corolla LE Eco, designed specifically for fuel efficiency, reaches closer to 35 MPG combined. However, neither of these vehicles offers standard all-wheel drive. If you opt for AWD on a Nissan Rogue Sport, a similarly sized SUV, fuel economy drops to around 27 MPG combined. The Impreza delivers better MPG than competing vehicles equipped with ALL-WHEEL DRIVE.

Tips to maximize efficiency

Gentle acceleration is key to squeezing the most miles out of every gallon. The Impreza’s CVT responds best to a light foot on the accelerator. Avoid aggressive starts and stops, instead opting for smooth, gradual acceleration whenever possible. Anticipate traffic flow to minimize braking and maintain a steady speed.

Keep your tires properly inflated. Low tire pressure increases rolling resistance, which forces the engine to work harder and consume more fuel. Check your tire pressures regularly, at least once a month, and inflate them to the recommended levels, found on the sticker inside the driver’s side door jamb.

Minimize unnecessary weight in the vehicle. The heavier the car, the more fuel it burns. Remove any unnecessary items from the trunk and passenger compartment. Carrying around extra weight significantly reduces fuel efficiency, especially around town. Remember, IMPREZA MPG across all years is also impacted by weight, so keeping the car’s loading at a minimum is a good practice overall.

Take advantage of the cruise control on the highway. Using cruise control helps maintain a constant speed, which reduces unnecessary acceleration and deceleration. This leads to more consistent and efficient fuel consumption. However, avoid using cruise control in hilly terrain, where it can sometimes lead to inefficient gear changes.

Consider using the air conditioning sparingly. The air conditioner puts an extra load on the engine, which reduces fuel efficiency. When possible, try opening the windows for ventilation or using the fan without the air conditioning. And make sure all windows and the sunroof are properly sealed when using the A/C because that will impact performance.
