31 MPG combined isn’t going to set any records, but for the 2015 Subaru Impreza AWD 2.0L with its automatic transmission, it’s a key part of its appeal. This isn’t a hypermiling hatchback; it’s a compact car that delivers confident all-wheel drive in all kinds of weather. Its buyers prioritize that capability and longevity over segment-leading fuel efficiency, finding 31 MPG a reasonable compromise.

City and highway performance

The EPA estimates of 28 MPG in the city and 36 MPG on the highway accurately reflect how the Impreza drives. The naturally aspirated 2.0L engine offers adequate power, but requires more effort in urban environments, impacting mileage. On the open road, the continuously variable transmission (CVT), marketed as AV-S6 by Subaru, keeps the engine in its most efficient range once cruising speed is reached, helping achieve the respectable highway figure. These numbers show the Impreza AWD’s balance, serving city dwellers and highway commuters even when the weather is bad.

Annual fuel cost

The EPA calculates that the annual fuel cost for the 2015 Subaru Impreza AWD 2.0L is $1,400. This figure is based on driving 15,000 miles per year and assumes fuel prices reflect national averages at the time of calculation. Individual fuel costs will vary depending on driving habits, local fuel prices, and the type of fuel used. However, $1,400 provides a standardized baseline for comparison with other vehicles and helps potential buyers understand the ongoing running expenses of owning an Impreza. Owners can IMPREZA MPG across all years to see how it ranks as it ages.

Real-world expectations

While the EPA provides consistent benchmarks, real-world fuel economy often differs. Impreza owners frequently report figures within a few MPG of the official ratings, but aggressive driving, frequent short trips, and the use of accessories like roof racks can decrease fuel efficiency. You can achieve or even exceed the EPA estimates with careful driving habits, regular maintenance, and careful tire inflation. The AWD system, while beneficial for traction, adds weight and complexity, which slightly reduces fuel economy compared to similar front-wheel-drive vehicles. Drivers can actively manage fuel consumption if they are aware of these factors.

How it compares

The 2015 Impreza is competitive compared to other compact cars with all-wheel drive. The Mazda3, for example, offers a more engaging driving experience, achieving around 33 MPG combined in its front-wheel-drive configuration. However, opting for all-wheel drive drops its MPG closer to the Impreza. Similarly, the Toyota Corolla, primarily a front-wheel-drive vehicle, can achieve around 35 MPG combined but sacrifices all-weather capability. The Impreza is a good choice for buyers who want all-wheel drive AND decent fuel economy. Those considering other Subaru models can review all Subaru fuel economy data to assess what is most important to them in a vehicle.

Tips to maximize efficiency

Gentle acceleration and smooth braking are key to maximizing fuel economy in any vehicle, but are especially important in the Impreza with its CVT. Avoid harsh acceleration from a stop, which forces the engine to rev higher and consume more fuel. Anticipating traffic conditions and allowing the car to coast when possible will minimize unnecessary fuel consumption.

Proper tire inflation plays a significant role in fuel efficiency. Check your tire pressure regularly and maintain the recommended pressure as listed on the driver’s side doorjamb. Underinflated tires create more rolling resistance, increasing fuel consumption. This is even more important for AWD vehicles, as differences in tire pressure between axles can impact system performance.

Minimize the use of accessories that drain the battery, such as air conditioning, especially during short trips. The alternator must work harder to recharge the battery, which in turn increases fuel consumption. Use natural ventilation whenever possible. Depending on your climate, this may be more practical in some conditions versus others.

Regular maintenance is critical for optimal fuel economy. Keeping the engine properly tuned, replacing air filters, and using the recommended grade of oil can all help improve MPG. Consult your owner’s manual for recommended maintenance schedules and stick to them. Regularly servicing your car will help keep everything running as smoothly and efficiently as possible.

Reduce unnecessary weight in the vehicle. Carrying extra cargo adds to the overall weight, requiring more energy to accelerate and maintain speed. Removing items you don’t need will lighten the load and contribute to better fuel efficiency. When carrying large amounts of cargo, keep the weight rating of your tires in mind.
