29 MPG combined from the 2015 Subaru XV Crosstrek isn’t going to win any hypermiling contests, but it’s a respectable figure for a small, genuinely capable all-wheel-drive crossover. This car answers the question for buyers who need confident traction for ski trips or gravel roads, but aren’t willing to sacrifice fuel efficiency for a larger SUV. The XV Crosstrek always prioritized practicality and capability over outright efficiency, and that remains true.

City and highway performance

The EPA estimates the 2015 Subaru XV Crosstrek at 26 MPG in the city and 33 MPG on the highway. This difference reflects the compromises of the engine and drivetrain. The 2.0L 4-cylinder engine, while reliable, needs to work harder at lower speeds, especially with the added weight and friction of the all-wheel-drive system. On the open road, however, the tall gearing of the “AV-S6” continuously variable transmission (CVT) allows the engine to cruise at lower RPMs, improving efficiency. Owners who spend more time on the highway will likely see numbers closer to or even exceeding the EPA’s estimate.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2015 Subaru XV Crosstrek at $1,500. This figure is based on driving 15,000 miles per year and using the national average fuel price. Your actual expenses may vary depending on your driving habits and local fuel costs. But $1,500 provides a useful benchmark for comparison against other vehicles, especially those with all-wheel drive.

Real-world expectations

While the EPA figures are a solid baseline, real-world fuel economy for the 2015 Subaru XV Crosstrek often varies. Many owners report achieving figures slightly below the combined 29 MPG rating, especially in areas with frequent stop-and-go traffic or hilly terrain. Aggressive driving habits, carrying heavy loads, and using roof racks all contribute to a decrease in fuel efficiency. Careful drivers who prioritize smooth acceleration and maintain consistent speeds on the highway can often match or even exceed the EPA’s estimates. The XV Crosstrek’s fuel efficiency is relatively sensitive to driving style.

How it compares

The 2015 Subaru XV Crosstrek faces competition from a variety of small crossovers and hatchbacks. The Mazda CX-3, for example, offers a more engaging driving experience and achieves a comparable 29 MPG combined in its all-wheel-drive configuration. The Nissan Juke (since discontinued) offered similar quirky styling and a more powerful engine, but its fuel economy lagged behind the Subaru at 28 MPG combined with AWD. Even the Honda HR-V, known for its fuel efficiency, matches the XV Crosstrek at 29 MPG combined with all-wheel drive. It matches the fuel economy of competitors like the HR-V while offering off-pavement capability, especially when considering all all Subaru fuel economy data.

Tips to maximize efficiency

The Subaru XV Crosstrek’s CVT transmission is designed for efficiency, so avoid sudden acceleration and hard braking. Smooth, gradual inputs will help the transmission stay in its optimal gear ratio and minimize fuel consumption. Expect traffic flow to avoid unnecessary stops.

Tire pressure is important in fuel economy. Check your tires regularly and maintain the recommended pressure. Underinflated tires increase rolling resistance, which leads to decreased fuel efficiency. Refer to the sticker on the driver’s side doorjamb for the correct tire pressure.

The added weight of cargo and accessories such as roof racks can significantly impact fuel economy. Remove any unnecessary items from your vehicle and take off roof racks when they are not in use. Reducing weight and improving aerodynamics will translate into better gas mileage.

The XV Crosstrek uses a 2.0L naturally aspirated engine. Using the recommended regular unleaded gasoline is cost-effective, and it avoids any potential issues associated with higher octane fuels that the engine is not designed to use.
