29 MPG combined is a respectable figure for the 2021 Subaru Crosstrek AWD 2.5L 4-cyl, especially considering this vehicle’s priorities: reliable all-wheel drive, a practical hatchback design, and enough ground clearance for off-pavement adventures. This isn’t a hyper-efficient econobox, it’s a ruggedly capable, adventure-ready compact SUV that sips fuel modestly. Its target demographic—outdoorsy types, city dwellers facing harsh winters, and anyone who values practicality—accepts this fuel economy because it unlocks the Crosstrek’s core strengths.

City and highway performance

The EPA estimates show the Crosstrek’s split personality. Its 27 MPG city rating is commendable, highlighting its maneuverability and efficiency in stop-and-go traffic. The short gearing of the continuously variable transmission (CVT) helps, providing brisk off-the-line acceleration without straining the engine. On the highway, the Crosstrek achieves a laudable 34 MPG. This showcases the engine’s ability to cruise efficiently at steady speeds, making long-distance road trips viable. This difference between city and highway figures reflects the blend of driving conditions the typical Crosstrek owner will encounter.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2021 Subaru Crosstrek AWD 2.5L 4-cyl is $1,500. This is based on driving 15,000 miles per year and using national average fuel prices. It’s a useful benchmark for budgeting and comparing the Crosstrek against its competitors. Consider this a starting point, your actual fuel costs will vary based on your driving habits and local fuel prices. Even with fluctuating gas prices, prospective owners can factor this cost into their budget.

Real-world expectations

While the EPA estimates are a helpful guide, real-world fuel economy can vary. The Crosstrek’s standard all-wheel-drive system adds weight and rolling resistance, which can impact fuel efficiency, especially in city driving. Aggressive acceleration, frequent hill climbs, and carrying heavy loads will also decrease MPG. Conversely, prioritizing smooth acceleration, maintaining consistent speeds on the highway, and keeping the vehicle properly maintained can help you achieve or even exceed the EPA estimates. Consider all Subaru fuel economy data to get a better sense.

How it compares

The Crosstrek’s fuel economy stacks up reasonably well against its competitors. The Mazda CX-30 with its standard 2.5L engine achieves a combined 28 MPG, slightly below the Crosstrek. A front-wheel drive Toyota C-HR boasts 29 MPG combined, matching the Crosstrek but sacrificing all-weather capability. The Nissan Kicks, a smaller and less capable SUV, achieves a stellar 33 MPG combined due to its markedly lower weight and lack of all-wheel drive. This illustrates the tradeoff inherent in the Crosstrek: capability comes with a slight compromise in fuel efficiency. Compare to CROSSTREK MPG across all years to see trends and performance.

Tips to maximize efficiency

Gentle acceleration is key to maximizing fuel economy in the Crosstrek. The CVT is programmed to prioritize efficiency, but it can still rev the engine higher if you demand rapid acceleration. A smooth and steady foot will keep the engine in its best range for fuel consumption.

Tire pressure plays a significant role. Ensure your tires are inflated to the recommended pressure listed on the driver’s side door jamb. Under-inflated tires increase rolling resistance, which can noticeably decrease fuel economy. A quick check with a tire pressure gauge every couple of weeks can make a surprisingly large difference.

Minimize unnecessary weight. Carrying around extra cargo will put a strain on the engine and reduce fuel efficiency. Remove anything you don’t need from the vehicle, such as sporting equipment or tools, to lighten the load.

Consider using the SI-DRIVE system carefully. The “Intelligent” mode prioritizes fuel efficiency by limiting throttle response and adjusting transmission mapping. While it may make the Crosstrek feel less peppy, it can contribute to noticeable fuel savings, especially in city driving. Switch to “Sport” mode only when you need extra power for passing or merging.
