21 MPG combined isn’t a selling point for the 2016 Subaru WRX. It’s the price of admission. People don’t buy this car for its low fuel consumption. They buy it for its rally-bred DNA, its turbocharged punch, and its tenacious all-wheel drive. Fuel economy is, realistically, an afterthought for the typical WRX buyer. They prioritize performance and practicality (four doors, usable trunk) over using less gas, and they accept the consequences.

City and highway performance

The EPA estimates for the 2016 WRX 2.0L 4-cyl with the automatic (AV-S8) transmission reveal the realities of driving a performance-oriented car. 18 MPG in the city reflects the constant stop-and-go driving, the temptations to dip into the turbo’s power, and the inherent inefficiencies of an engine designed for boost. The 24 MPG highway rating is more palatable, but even that figure is hardly class-leading. Achieving even these numbers requires a disciplined right foot. Frequent bursts of acceleration or sustained high-speed cruising will quickly reduce fuel economy.

Annual fuel cost

The EPA calculates the annual fuel cost for the 2016 Subaru WRX 2.0L at $2,750. This figure is based on driving 15,000 miles per year, assuming a national average fuel price. Actual fuel costs will vary based on individual driving habits, local fuel prices, and the type of fuel used. The WRX requires premium fuel, which typically carries a higher price per gallon, directly impacting the annual cost. Because driving style significantly affects fuel economy in a turbocharged car, many WRX owners will likely exceed this $2,750 estimate.

Real-world expectations

Owners posting on forums and fuel economy tracking sites often report figures that hover around the EPA estimates, but rarely exceed them. Expect 17-20 MPG in typical city driving and around 22-25 MPG on the highway. Aggressive driving can easily drop these figures into the low teens. Conversely, religiously adhering to efficient driving techniques *might* squeeze out slightly better numbers, but the WRX encourages spirited driving, making hypermiling a constant battle against the car’s nature.

How it compares

Compared to other performance-oriented vehicles, the 2016 WRX’s fuel economy is neither exceptional nor abysmal. For instance, a 2016 Volkswagen GTI, equipped with its 2.0L turbo and DSG automatic, achieves around 25 MPG combined, significantly better than the WRX. A Honda Civic Si from the same year, with its naturally aspirated engine and manual transmission, can easily achieve 30 MPG on the highway. On the other end of the spectrum, a V8-powered Ford Mustang GT sits closer to 19 MPG combined. The comparison highlights the compromise the WRX buyer makes. They sacrifice some fuel efficiency for the benefits of standard all-wheel drive and the unique driving experience the WRX provides.

Tips to maximize efficiency

The easiest way to improve fuel economy in a WRX is to resist the urge to constantly accelerate hard. Gentle throttle inputs, smoother braking, and anticipating traffic flow will all contribute to better mileage. The turbocharged engine is particularly sensitive to throttle inputs, so avoid sudden bursts of acceleration whenever possible.

Ensure your tires are properly inflated. Under-inflated tires increase rolling resistance, which directly impacts fuel economy. Check the tire pressure regularly and inflate them to the recommended pressure listed on the driver’s side door jamb. This simple step can make a noticeable difference.

Minimize idling. Modern engines warm up relatively quickly, so there’s no need to let the car idle for extended periods, especially in warmer weather. If you’re stopped for more than a minute or two, consider turning off the engine. Idling consumes fuel without covering any distance.

Consider remapping the ECU (engine control unit). While this might seem counterintuitive for fuel economy, a professional tuner can optimize the engine’s performance for efficiency. A custom tune can fine-tune the air-fuel ratio and ignition timing to deliver more power with less fuel consumption, although this comes with its own set of considerations regarding warranty and long-term engine health.
