Is the Subaru Impreza good on fuel?
The Subaru Impreza generally offers solid fuel economy for an all-wheel-drive compact, especially with the CVT. Expect about 28 mpg in the city and 36–38 mpg on the highway, with a combined figure in the low to mid-30s. Manual variants tend to be less economical.
Overview: what to expect from the Impreza's fuel economy
The Impreza's efficiency is shaped by its standard all-wheel drive (AWD), boxer engines, and available transmissions. AWD improves traction in wet or snowy conditions but adds weight and drivetrain losses that can nudge fuel economy downward relative to front-wheel-drive rivals. In recent model years, Subaru has maintained the 2.0-liter engine paired with a CVT across trims, aiming to balance performance with efficiency.
Powertrain and transmission impact
Two main configurations influence economy: a CVT with AWD and, on older or specialty versions, a 5-speed manual with AWD. CVT models typically maximize highway efficiency and smooth power delivery, while manuals tend to offer more engaging driving but lower fuel economy. Real-world results also hinge on tires, weather, and load.
EPA ratings by configuration
These figures reflect common configurations in recent years and illustrate how transmission choice and AWD affect efficiency. Actual numbers may vary by year and trim.
- CVT with AWD: approximately 28 mpg city / 36–38 mpg highway; about 32–34 mpg combined.
- Manual transmission with AWD: roughly 23–25 mpg city / 30–34 mpg highway; about 26–28 mpg combined.
- Note: In the US, AWD is standard on most Impreza models, which tends to lower efficiency versus some front-wheel-drive competitors but provides all-weather capability.
Despite the AWD penalty, the CVT-equipped Impreza remains competitive in the AWD compact segment, particularly for highway efficiency and predictable, steady cruising.
Real-world fuel economy and influencing factors
Real-world mpg depends on conditions beyond official ratings. The following factors commonly affect the Impreza’s fuel economy in daily use.
- Driving style: smooth acceleration and steady speeds improve mpg more than aggressive driving.
- Terrain and weather: highway driving in mild conditions yields better fuel efficiency than frequent stops, hills, or cold starts with climate control running.
- Tire condition and type: properly inflated, low-rolling-resistance tires can boost efficiency; winter tires or heavy tires may reduce it.
- Maintenance: clean air filters, fresh spark plugs, and timely servicing help sustain mpg.
- Load and aerodynamics: roof racks, heavy cargo, or added aerodynamic drag reduce mpg.
- AWD impact: standard AWD adds weight and drivetrain losses; the mpg penalty is typically modest on steady highway runs but more noticeable in urban driving.
In practice, CVT models commonly land in the low-to-mid 30s combined, while manual configurations sit lower. Winter conditions or heavy use of climate control can push numbers down further.
How the Impreza stacks up against rivals
The Impreza’s standout feature is its standard AWD, which provides traction and confidence in adverse weather. That capability comes with a trade-off in fuel economy. When compared with rivals that offer FWD or optional AWD, the Impreza may show slightly lower combined mpg, though newer CVTs have narrowed the gap on highway efficiency. For buyers who prioritize all-weather capability, the Impreza remains a competitive choice within the AWD compact segment.
Maximizing fuel economy with the Impreza
Owners can optimize efficiency through practical driving habits and routine maintenance. The following tips help ensure you get the best possible mileage from your Impreza.
- Keep tires inflated to the manufacturer’s recommended pressure for optimal rolling resistance.
- Drive smoothly: gentle acceleration and steady speeds improve mpg more than rapid bursts of power.
- Avoid prolonged idling; if stopped for more than a minute, turn off the engine or use stop-start features if equipped.
- Use cruise control on highways when appropriate to maintain steady speeds.
- Plan trips to minimize stop-and-go driving and combine errands when possible.
- Maintain basic vehicle health: regular oil changes, clean air filters, and timely spark plug replacements.
These practices can yield tangible gains, especially in city-to-highway transitions and during winter driving when heating and defogging increase energy use.
Summary
The Subaru Impreza is a practical choice for buyers who want all-wheel-drive capability without sacrificing too much fuel economy. CVT-equipped models typically achieve roughly 28 mpg in the city and 36–38 mpg on the highway, with a combined rating in the low-to-mid-30s; manual versions are less efficient. Real-world numbers vary with driving conditions, climate control use, and maintenance. If AWD traction is a priority, the Impreza offers competitive efficiency within its class; if outright mpg is the top priority and AWD isn’t needed, some rivals may offer higher fuel economy. Always check the EPA ratings for the exact year and trim you’re considering.
