19 MPG combined. It’s a data point that elicits winces from Prius drivers and shrugs from those behind the wheel of a lifted pickup. But for the owner of a 2016 Subaru WRX with the 2.5L engine and six-speed manual, it’s simply the price of admission. The car isn’t bought for maximizing gasoline. It’s bought for visceral thrills, for rallying fantasies realized on backroads, and for all-weather performance that few vehicles can match. The fuel economy is a known quantity, a concession made for performance.

City and highway performance

The EPA breaks down that combined figure into 17 MPG in the city and 23 MPG on the highway. Those numbers accurately reflect the driving dynamics of the WRX. The city figure suffers because the car practically begs you to exploit its turbocharged power at every green light. The turbo lag is present, a brief pause before the boost kicks in with exhilarating force, encouraging aggressive starts. The highway figure, while better, still trails other vehicles, partly due to the car’s gearing. Even in sixth gear, the engine hums at a relatively high RPM, ready to pounce with minimal downshifting available at a simple press the pedal. The WRX isn’t loafing, it’s poised.

Annual fuel cost

That 19 MPG combined figure translates to an estimated annual fuel cost of $3,050. The EPA calculates this based on driving 15,000 miles per year and using national average fuel prices. Of course, this figure will fluctuate depending on your driving habits and where you live, as fuel prices vary regionally. But $3,050 is a stark reminder that the WRX’s performance comes at a monetary cost. It’s a cost that most WRX owners are willing to accept, viewing it as part of the overall ownership experience.

Real-world expectations

While the EPA numbers provide a baseline, real-world fuel economy often varies. Aggressive driving, stop-and-go traffic, and even tire pressure can significantly impact your MPG and the WRX’s numbers are known to vary due to the nature of it’s use. Owners who frequently engage in spirited driving or live in congested areas will likely see figures closer to the city rating, or even lower. Conversely, those who primarily drive on the highway and exercise restraint can sometimes achieve numbers slightly above the EPA estimate. However, it’s best to approach WRX ownership expecting to consistently achieve around the EPA combined figure to avoid disappointment. The car’s inherent responsiveness and inviting turbo invites fun, but fuel burn.

How it compares

The 2016 WRX’s fuel economy doesn’t exactly top its class. A 2016 Volkswagen GTI with the manual transmission, a frequent rival, manages closer to 25 MPG combined. Newer Subaru WRX models can achieve 22 MPG Combined, according to WRX MPG across all years. Even the rear-wheel-drive Ford Mustang EcoBoost, while a very different beast to drive in snow, boasts superior MPG in the high 20’s. But these comparisons don’t always resonate with the WRX buyer because they prioritize the Subaru’s standard all-wheel drive, its distinctive boxer engine rumble, and its inherent rally-bred character, all factors that outweigh a few extra miles per gallon for the right enthusiast. Many also value the easy tuning potential of the 2.5L turbo engine, leading to even worse gas mileage in pursuit of greater power.

Tips to maximize efficiency

While fuel economy might not be the primary concern for a WRX owner, there are still ways to minimize trips to the pump. Avoid excessive idling, especially during warm-up. Modern engines don’t require extended idling to reach operating temperature, and prolonged idling simply wastes fuel. Plan ahead to avoid traffic which minimizes stop and go driving, which is a fuel burner in this car.

Keep a close eye on tire pressure. Underinflated tires increase rolling resistance, which in turn reduces fuel economy. Check your tire pressure regularly and inflate them to the recommended level. Regular maintenance on all Subaru fuel economy data is very important to keep it in good shape.

Resist the urge to constantly unleash the turbo. While the WRX’s performance is addictive, using the boost frequently will significantly decrease fuel economy. Smooth acceleration and anticipating traffic flow can help conserve fuel.

Consider using premium fuel, even though it’s not strictly required. While the car can run on regular unleaded, premium fuel with a higher octane rating can potentially improve performance and fuel economy, primarily when using the turbo for longer periods. For short jaunts and casual driving, it isn’t as necessary as when wanting to push up the performance.
