Laboratory testing conducted by the Environmental Protection Agency (EPA) provides a standardized baseline for comparing vehicle efficiency under controlled parameters. However, actual drivers in Plainfield and the surrounding Chicago suburbs often operate in conditions that laboratory dynos simply cannot replicate. Factors such as extreme seasonal temperature shifts, cargo weight, tire selections, and individual driving styles play a massive role in determining your actual miles per gallon.

For example, Illinois winters are notoriously harsh, and cold weather is a known fuel economy killer. During sub-zero days, engine oil is thicker, creating more internal drag; the engine takes longer to reach its optimal operating temperature, during which it burns a richer fuel mixture; and winter-blend gasoline contains less energy per gallon than summer blends. Furthermore, utilizing remote start features to warm up your vehicle before a morning commute on Route 59 means spending several minutes idling at 0 MPG, which directly drags down your tank average.

Conversely, summer driving in Illinois allows the Crosstrek to shine. Under warm conditions, the engine warms up almost instantly, and summer-blend fuel offers maximum energy efficiency. On open highway stretches like I-55 or the tollways heading toward Naperville, drivers frequently report meeting or even exceeding the official EPA highway ratings. Many drivers utilizing gentle acceleration and keeping their highway speeds around 65-70 MPH report achieving upwards of 34 to 35 MPG on long road trips.

In heavy suburban stop-and-go traffic around Joliet, real-world averages will naturally skew lower, typically landing in the 24 to 26 MPG range. Frequent acceleration from a complete stop requires the engine to overcome inertia repeatedly. However, Subaru’s Continuously Variable Transmission (CVT) does an admirable job of minimizing these losses by continuously adapting its gear ratios to keep the engine in its most efficient power band. Understanding this discrepancy helps pre-owned buyers set realistic expectations based on their daily driving routes.

The Standard 2.0-Liter Boxer Engine For many years, the 2.0-liter four-cylinder Subaru Boxer engine was the sole powertrain option available across the Crosstrek lineup. Generating 152 horsepower and 145 lb-ft of torque, this engine was specifically engineered to prioritize fuel efficiency over raw performance. In pre-owned models from the 2018-2023 generation, this engine paired with the CVT achieves an EPA-estimated 28 MPG city, 33 MPG highway, and 30 MPG combined. It is a highly reliable, efficient powerplant perfect for daily commuting around Plainfield.

The Mighty 2.5-Liter Boxer Engine Responding to driver requests for more passing power, Subaru introduced a larger 2.5-liter Boxer engine starting in the 2021 model year, standard on the Sport and Limited trims. This engine bumps output up to a robust 182 horsepower and 176 lb-ft of torque. Remarkably, this extra power comes with almost no fuel economy penalty. The 2.5-liter engine achieves an EPA-estimated 27 MPG city, 34 MPG highway, and 29 MPG combined. On the highway, it actually matches or beats the 2.0-liter engine due to its superior power-to-weight ratio.

Which Engine Fits Your Driving Style? Choosing between the two depends heavily on your daily driving routine. If your commute involves mostly flat highway cruising down I-55, the 2.5-liter engine offers superior overtaking confidence and highly comparable fuel economy. However, if you are looking for the absolute lowest purchase price on a pre-owned model and prioritize city-driving efficiency, the 2.0-liter engine remains an exceptional and highly economical choice that keeps operating costs to a minimum.

For buyers seeking to dramatically slash their carbon footprint and fuel consumption, the pre-owned market occasionally features the rare and highly desirable Subaru Crosstrek Hybrid (PHEV), offered between the 2019 and 2023 model years. This advanced powertrain combines a modified 2.0-liter engine with two electric motors and an 8.8-kWh lithium-ion battery pack. The result is a highly capable hybrid system that offers an EPA-rated 90 MPGe (Miles per Gallon Equivalent) when utilizing both electricity and gasoline.

When operating solely as a traditional hybrid after the electric battery depletes, the Crosstrek PHEV still delivers an impressive EPA-estimated 35 MPG combined. This makes it significantly more efficient than its gas-only counterparts. However, the real value lies in its electric-only capability, which allows drivers to run local errands without burning a single drop of fuel.

With an EPA-estimated all-electric range of up to 17 miles on a full charge, the Crosstrek Hybrid is perfectly optimized for short, daily commutes. For residents in Plainfield, a round-trip drive to downtown Naperville or a quick run to the local grocery store can be completed entirely on electric power. Charging the battery is incredibly convenient, taking around two hours with a standard Level 2 (240V) charger or approximately five hours using a conventional 120V household outlet.

Finding one of these highly efficient plug-in hybrids in the pre-owned market requires a dedicated partner. At Hawk Subaru, we continuously source high-quality pre-owned Subaru vehicles.

First Generation (2013-2017) The original Crosstrek models represent the lowest barrier to entry in the pre-owned market. Powered by an early version of the 2.0-liter Boxer engine, these models typically achieve around 26 MPG city and 32 MPG highway (with CVT). While they lack the modern refinement and standard EyeSight safety suites of newer generations, they offer incredible mechanical durability, standard AWD, and exceptional utility for drivers working with a tighter budget.

Second Generation (2018-2023) This generation is widely considered the absolute sweet spot for pre-owned value. Built on the Subaru Global Platform, these models offer drastically improved crash safety, a much quieter cabin, and standard Apple CarPlay and Android Auto. Fuel economy climbed to a stellar 28 city / 33 highway MPG with the CVT, and starting in 2021, the optional 2.5-liter engine added much-needed power without sacrificing efficiency. EyeSight Driver Assist also became widely available.

Third Generation (2024-Present) If you want the absolute latest tech and safety features under factory warranty, a nearly-new 2024 or 2025 pre-owned Crosstrek is a phenomenal buy. This generation refined the CVT even further, offering ultra-smooth power delivery and a redesigned interior featuring a massive 11.6-inch tablet-style touchscreen. Fuel economy remains robust at 27 city / 34 highway MPG, representing the ultimate modern commuter vehicle.

Subaru’s Lineartronic Continuously Variable Transmission (CVT) is the primary reason why an all-wheel-drive crossover can achieve over 33 MPG on the highway. Unlike a traditional automatic transmission that has a fixed number of gears, the CVT utilizes a heavy-duty metal belt and pulley system that can continuously adjust its diameter. This infinite variability allows the engine to operate at its absolute peak efficiency at all times.

When cruising on flat stretches of Route 59 or keeping pace with traffic on I-55, the CVT is engineered to drop engine RPMs down to a whisper—often below 1,500 RPM. This incredibly low engine speed burns minimal fuel, maximizing your cruising range. The CVT also features stepped ratio programming that mimics traditional shifts under heavy acceleration, giving drivers a natural, satisfying driving feel while preserving top-tier fuel economy.

For driving enthusiasts, older pre-owned Crosstrek models (up to the 2023 model year) could be configured with a 6-speed manual transmission on standard Base and Premium trims. While manual transmissions offer a engaging, tactile connection to the car, they carry a highly significant fuel economy penalty in the Crosstrek. The manual-equipped 2.0-liter engine achieves only an EPA-estimated 22 MPG city and 29 MPG highway.

This drop of nearly 5 MPG in the city and 4 MPG on the highway is a product of gear ratio limitations and the lack of automatic efficiency optimization. Furthermore, manual Crosstrek models do not come equipped with Subaru's advanced EyeSight driver assistance package in older model years. If maximizing fuel savings on your daily Illinois commute is your primary goal, choosing a pre-owned Crosstrek equipped with the Lineartronic CVT is highly recommended.

Routine Maintenance & Tires Keeping your pre-owned Crosstrek in top mechanical shape is critical for maintaining its fuel efficiency. Engine air filters should be replaced regularly to prevent air-flow restriction, and routine wheel alignments ensure your tires roll straight without creating extra fuel-sapping drag. Additionally, tire pressure drops as temperatures cool down in the fall; driving on underinflated tires increases rolling resistance, dragging down your MPG. Ensure you use the correct oil viscosity during your regular service visits.

Remove Unused Roof Accessories The Crosstrek looks fantastic with a rugged roof basket or kayak rack, but these accessories disrupt the vehicle's aerodynamics. Roof racks, cargo carriers, and bicycle mounts create immense wind resistance, especially at highway speeds. Studies show that a roof basket can decrease highway fuel economy by up to 10% to 15%. Removing these accessories when they are not in use and keeping the roof clean is one of the simplest ways to immediately boost your highway MPG.

Optimize Your Driving Habits Your right foot is the single most influential factor in your vehicle's fuel economy. Aggressive acceleration and hard braking waste energy. Utilizing the Subaru EyeSight system’s Adaptive Cruise Control on long highway stretches can help maintain a steady pace, reducing unnecessary throttle adjustments. If your Crosstrek features the SI-DRIVE system, keeping the vehicle in 'Intelligent' (I) mode instead of 'Sport' (S) mode ensures smoother, more efficient acceleration curves for daily commutes.

Historically, choosing an all-wheel-drive or four-wheel-drive vehicle meant accepting a massive penalty in fuel efficiency. Traditional systems added immense weight, mechanical complexity, and parasitic drivetrain loss. Many older full-time 4WD systems required heavy transfer cases and heavy components that reduced gas mileage down to the teens. However, Subaru's Symmetrical All-Wheel Drive is engineered from the ground up to completely shatter this stereotype.

The brilliance of Subaru’s Symmetrical AWD lies in its layout. The system is mounted directly in-line with the horizontally opposed Boxer engine, creating a perfectly balanced, symmetrical design. Because the power flows in a straight line from the engine through the transmission to all four wheels, internal friction is significantly reduced. This minimizes drivetrain losses and allows the Crosstrek to deliver fuel economy ratings that rival many front-wheel-drive competitors in the compact class.

Furthermore, Subaru's Active Torque Split system continuously monitors driving conditions to optimize power distribution. Under normal highway cruising, the system distributes power in a highly efficient 60:40 front-to-rear ratio, reducing drag and saving fuel. If the system detects slippage on icy or rain-slicked Plainfield roads, it instantly routes power to the wheels with the best traction. You get the safety of continuous AWD without the heavy fuel economy penalty.

When comparing a pre-owned Crosstrek to other compact crossovers, keep in mind that many competitors only offer all-wheel drive as an expensive add-on option that reduces their efficiency. With the Crosstrek, the Symmetrical AWD is integrated directly into the car's DNA, offering maximum confidence during severe winter weather while maintaining a combined average of around 30 MPG. It is the ultimate compromise-free driving experience.

The Math Behind the Efficiency Many drivers underestimate how much money they can save by switching from a less efficient vehicle to a highly economical crossover. If you are currently driving an older, larger midsize SUV that averages around 20 MPG, your monthly fuel bills can add up rapidly. Upgrading to a pre-owned Subaru Crosstrek that averages an impressive 30 MPG combined can put a significant amount of money back into your wallet every single month.

Annual Savings Projections Let's look at the numbers. Assuming you drive an average of 15,000 miles per year and gas costs an average of $3.75 per gallon in the Plainfield area, a 20 MPG vehicle will consume 750 gallons of fuel annually, costing $2,812.50. In contrast, a pre-owned Subaru Crosstrek averaging 30 MPG combined will consume only 500 gallons of fuel over that same distance, costing $1,875.00. That is an immediate annual savings of $937.50.

Long-Term Financial Benefits Over a typical five-year ownership period, that single vehicle switch translates to $4,687.50 in total fuel savings! This is money that can go directly toward your vehicle payment, savings, or other household expenses. Furthermore, because Subaru vehicles hold their resale value incredibly well, you get to enjoy low operating costs alongside exceptional long-term equity. It is a smart financial decision from every angle.
