The 2013 Subaru WRX offers a blend of turbocharged performance, standard all‑wheel drive, and engaging driving dynamics that still appeal to drivers today. While modern models bring updated tech and efficiency gains, many enthusiasts reference the 2013 WRX as a benchmark for real‑world MPG and everyday usability.
Below is a detailed snapshot of how the 2013 WRX performs in the real world, including official estimates, observed traffic and highway results, and key variables that influence fuel economy.
| Condition | MPG (Official) | MPG (Reported City) | MPG (Reported Highway) | Primary Influences |
|---|---|---|---|---|
| EPA Estimate | 26 | — | 36 | Test cycle, moderate driving |
| Mixed Traffic | — | 22 | 30 | Stop‑and‑go, moderate speeds |
| Highway Cruising | — | — | 33 | Steady RPM, AWD engaged |
| Towing or Aggressive | — | 18 | 24 | Higher load, spirited throttle |
Real World Driving MPG in the 2013 WRX
In everyday use, most 2013 WRX drivers see between 22 and 28 MGA in mixed driving, depending on traffic density and how often the turbo is called upon. Stop‑and‑go commutes with frequent acceleration can push fuel consumption higher, while periods of steady highway cruising allow the MPG to climb toward the upper end of the range.
Cold starts, short trips, and low ambient temperatures further reduce real world MPG because the engine and catalytic converter require more time to reach optimal temperature. Drivers in colder climates may notice a temporary dip in MPG during winter months, especially when using heated seats and defrosters.
Fuel grade also plays a role; the turbocharged boxer engine performs best on premium fuel as specified in the owner’s manual, though some drivers opt for regular gasoline and compensate with slightly altered driving habits. The knock sensor system can adjust timing to protect the engine, but this may lead to a small MPG penalty under certain conditions.
Highway Versus City MPG Differences
Highway driving favors the 2013 WRX because steady throttle and higher gears allow the turbocharged engine to operate efficiently. Observed highway MPG often reaches the low‑mid 30s, especially when cruise control is used at legal speed limits and the driver avoids unnecessary acceleration.
In city environments, frequent stops and lower average speeds mean the WRX spends more time in lower gears and higher RPM ranges. Under these conditions, MPG can fall into the low 20s as the engine works harder to maintain momentum and the turbo spools more often.
Route planning, such as avoiding steep grades and heavy congestion, can improve real world MPG. Using navigation tools to select smoother roads and anticipating traffic flow helps keep the engine in its efficient power band more of the time.
Factors That Affect MPG
Several vehicle specific and external factors influence how many miles per gallon the 2013 WRX delivers. Tire pressure, alignment, and the condition of the air filter all affect rolling resistance and engine load. Keeping up with scheduled maintenance helps sustain optimal efficiency.
Driver behavior is one of the most significant variables, as aggressive throttle inputs, rapid acceleration, and high speed cruising increase fuel consumption. Smooth, anticipatory driving with gradual braking and steady acceleration can noticeably raise MPG over time.
Weight and cargo also matter; removing unnecessary items from the cabin and trunk reduces the load on the drivetrain. Roof racks and open windows at highway speeds introduce aerodynamic drag, which can lower MPG, especially on long trips.
Key Takeaways for Owning a 2013 Subaru WRX
- Expect real world MPG in the low to mid 20s for mixed driving, with highway figures in the low to mid 30s.
- Cold weather, short trips, and aggressive driving can noticeably reduce fuel economy.
- Using premium fuel as recommended helps protect the turbocharged engine and maintain consistent MPG.
- Simple changes like proper tire pressure, smoother throttle inputs, and reducing excess weight can improve efficiency.
- Planning routes to minimize stop‑and‑go traffic and aerodynamic drag supports better overall MPG.
FAQ
Reader questions
Why does my 2013 WRX get lower MPG in winter?
Colder temperatures cause longer warm‑up times, richer fuel mixtures, and increased use of accessories like heated seats and defrosters, all of which reduce cold weather MPG.
Is premium fuel required to maintain the turbocharged engine’s efficiency?
While the manufacturer recommends premium fuel for optimal performance and knock resistance, many drivers use regular gasoline and rely on the engine’s knock sensors, though this may slightly reduce MPG under stress.
How much does aggressive driving lower MPG in a WRX?
Hard acceleration and high speed driving can easily cut MPG by 20 to 30 percent compared to smooth, conservative driving, especially in stop‑and‑go conditions.
Can aftermarket parts affect the fuel economy of a 2013 WRX?
Certain intake and exhaust modifications may improve throttle response, but gains in MPG are often modest, while some changes can slightly reduce efficiency if they alter the air fuel ratio or add weight.
