The 2023 Subaru Solterra Limited and Touring AWD models have a combined 102 MPGe rating, a figure that needs context. This isn’t a traditional MPG rating, it’s MPGe, or “miles per gallon equivalent,” reflecting how much energy the Solterra uses compared to a gasoline vehicle. This all-electric SUV prioritizes practicality and Subaru’s hallmark all-wheel-drive capability over maximum range, and buyers usually accept this trade-off. These are typically environmentally conscious consumers, city dwellers, or suburban families seeking a zero-emission daily driver with the confidence of AWD for snowy commutes or weekend trips. Solterra owners value the vehicle’s comfortable interior, advanced safety features, and the Subaru brand’s reputation for reliability, understanding that range and charging infrastructure are still improving.

City and highway performance

The Solterra’s MPGe ratings are 111 in the city and 93 on the highway. This difference is normal for electric vehicles, which perform well in stop-and-go urban environments where regenerative braking recaptures energy. The city MPGe figure highlights the Solterra’s suitability for errands and commuting within urban areas, where it maximizes its efficiency and minimizes energy consumption. On the highway, the aerodynamic drag and constant speeds cause a drop in efficiency, impacting the range for longer journeys. This isn’t a major concern for target buyers who value the vehicle for regular short trips, knowing the overall benefit of it’s MPG rating.

Annual fuel cost

The Environmental Protection Agency (EPA) estimates the annual fuel cost for the 2023 Subaru Solterra Limited/Touring AWD at $700. This calculation assumes driving 15,000 miles per year and uses the national average electricity price. The actual cost of electricity may vary depending on location and charging habits (home versus public charging, time-of-use rates), but this figure provides a standard benchmark. The savings compared to a gasoline-powered SUV with similar capabilities can be substantial, especially with fluctuating gas prices. Many Solterra owners consider lower running costs to be a significant factor in their purchasing decision, offsetting the higher initial price of an electric vehicle.

Real-world expectations

While the EPA’s MPGe ratings offer a useful guide, real-world performance can vary based on several factors. Driving style, ambient temperature, terrain, and the use of climate control all influence the Solterra’s energy consumption. Aggressive acceleration, frequent hill climbs, and cold weather can significantly reduce range. However, gentle driving, preconditioning the battery while plugged in, and using the Solterra’s Eco mode can maximize efficiency. Owners should expect slightly lower numbers than the EPA estimates, especially during highway driving or in more challenging conditions. Monitoring the energy consumption display and adjusting driving habits can optimize range and reduce charging frequency.

How it compares

The Solterra competes in a growing segment of electric SUVs, each with its own strengths and weaknesses in terms of efficiency. The Hyundai IONIQ 5, for example, achieves up to 114 MPGe combined in the RWD Long Range configuration, or 101 MPGe combined in the AWD model, showing strong efficiency thanks to its advanced 800V charging architecture. The Kia EV6, mechanically similar to the IONIQ 5, offers up to 117 MPGe combined in RWD Long Range but also 105 MPGe combined in the AWD model. The Tesla Model Y Long Range achieves an estimated 122 MPGe combined, setting a high bar for electric SUV efficiency. Owners should research SOLTERRA MPG across all years and compare to all-wheel-drive or four-wheel-drive versions of those vehicles before making a final decision. While the Solterra’s MPGe is competitive, its appeal lies in its Subaru DNA, its standard AWD system (AWD comes standard, unlike competitors), its comfortable ride, and its ease of use, which attract buyers who prioritize these features over peak efficiency.

Tips to maximize efficiency

Take advantage of regenerative braking. The Solterra allows you to adjust the level of regenerative braking, which converts kinetic energy back into electricity when you lift off the accelerator. Try different settings to find one that suits your style and recovers energy, particularly in city traffic.

Precondition the battery when plugged in. Heating and cooling the battery use energy. By preconditioning the battery while the Solterra is plugged in, you can draw power from the grid instead of using the battery’s charge, especially during cold winter months. This feature is accessible through the Solterra’s infotainment system.

Drive smoothly and avoid aggressive acceleration. Rapid acceleration and hard braking use more energy. Anticipate traffic flow, maintain speed, and accelerate gently to conserve battery life and extend your range. This is important on the highway.

Monitor your tire pressure. Properly inflated tires reduce rolling resistance and improve fuel efficiency. Check your tire pressure regularly and inflate them to the recommended pressure listed on the doorjamb sticker. Ensure your tires are properly aligned to prevent wear and tear and any unnecessary energy drain.
