The 2017 Subaru WRX 2.0L with the automatic transmission gets 21 MPG combined, a figure that doesn’t deter its target audience. It’s not a car bought for its fuel-sipping abilities; it’s a performance machine designed to deliver thrills, and the MPG is accepted by those who prioritize spirited driving and all-weather capability over Prius-like efficiency. This WRX attracts driving enthusiasts who want practicality and daily-driver usability, but don’t want to compromise on responsiveness and a raw, connected driving experience. They understand the compromise isn’t perfect, and 21 MPG underscores that.

City and highway performance

Looking at the EPA figures reveals the 2017 WRX’s specific strengths and weaknesses depending on the environment. In the city, expect around 18 MPG. Stop-and-go traffic and the constant need to accelerate from a standstill impact fuel consumption, due to the engine’s eagerness to spool up the turbocharger. The WRX does better on the highway, achieving around 24 MPG. Maintaining a steady speed allows the engine to operate more efficiently, although even on the open road, an enthusiastic driver will find it difficult to resist the urge to dip into the turbo’s powerband, impacting economy. These numbers are highly dependent on driving style, of course, and aggressive acceleration will decrease those MPG figures significantly.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,750 for the 2017 Subaru WRX 2.0L with the automatic transmission. This calculation is based on driving 15,000 miles per year, using the EPA’s combined MPG figure, and assuming national average fuel prices. It’s a useful benchmark, but your actual fuel expenses will change based on your driving habits, the type of fuel you purchase, and the prevailing gas prices in your area. This figure assumes only regular fuel, and a WRX driven hard may benefit from, or require, premium fuel. The $2,750 figure should be considered a minimum, not a reliable expectation.

Real-world expectations

While the EPA provides a standardized measure of fuel economy, real-world results often vary. Expect the average 2017 WRX driver to see numbers slightly lower, especially if they frequently engage the car’s performance capabilities. A lighter foot and adherence to speed limits will improve your MPG, but the WRX is difficult to drive economically for extended periods. Its responsive engine and sharp handling encourage a more spirited driving style. Older WRX examples, especially those that have been modified or poorly maintained, might see even lower fuel economy than the EPA estimates. Review WRX MPG across all years to understand how fuel economy may change.

How it compares

Compared to other performance-oriented vehicles in its class, the fuel economy of the 2017 WRX is a mixed bag. The Volkswagen GTI, for example, often achieves better real-world MPG, with some owners reporting combined figures in the high 20s with the automatic transmission. The Honda Civic Si offers similarly better economy in most situations. However, neither of those vehicles offers the WRX’s standard all-wheel drive, important for many buyers in regions with challenging weather conditions. A Mitsubishi Lancer Evolution (pre-2016) is a closer performance and AWD competitor, but typically falls short of the WRX’s MPG figures. These comparisons are for the enthusiast considering daily usability. To explore all Subaru fuel economy data, review our other pages.

Tips to maximize efficiency

Resist the urge to floor the accelerator at every green light. The 2.0L turbo engine delivers plenty of power, but each hard acceleration increases fuel consumption. Smooth, gradual acceleration will save gas and extend the life of your tires.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressure regularly and inflate them to the recommended levels listed on the doorjamb sticker, being sure to check when tires are cold.

Shorter trips will also lower MPG. The engine is most efficient when warmed up, so frequent short trips prevent the engine from reaching optimal operating temperature and therefore increase fuel use. Combine errands into single trips to minimize cold starts.

Minimize idling. If you anticipate waiting for more than a minute or two, shut off the engine. Excessive idling consumes fuel without covering any distance. Modern engines are designed to restart quickly and efficiently, so it’s more economical to turn the engine off than to let it idle unnecessarily.
