The 2023 Subaru Solterra AWD gets 104 MPG combined, but this number needs context. It’s not a gasoline-powered vehicle achieving hybrid-like numbers. Instead, it’s an all-electric SUV, so 104 MPGe (miles per gallon equivalent) shows its efficiency compared to a gasoline vehicle. Reducing reliance on fossil fuels and adopting a zero-emission lifestyle motivates many buyers, even if other EVs have slightly better numbers.

City and highway performance

The Solterra’s MPGe ratings highlight its strengths and weaknesses. Its city rating of 114 MPGe suggests the electric motor’s regenerative braking system works well in stop-and-go traffic by recapturing energy and increasing range. However, the highway rating of 94 MPGe shows the effect of aerodynamic drag at higher speeds. Like all EVs, the Solterra’s efficiency drops noticeably on the open road. Drivers who mainly drive in cities will see the biggest benefit, while those who often take long trips may need to plan charging stops more carefully. Understanding this difference is key to managing expectations and getting the best range.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 Subaru Solterra AWD at $700. This figure is based on driving 15,000 miles per year, split between city and highway driving, using national average electricity prices. While individual charging costs will vary based on local electricity rates and charging habits (home vs. public charging), this $700 provides a useful benchmark for comparing the Solterra’s running costs to those of gasoline-powered SUVs and other EVs. For many, spending significantly less on “fuel” each year is a major selling point, which offsets the Solterra’s initial price.

Real-world expectations

While the EPA figures offer a standardized comparison, real-world MPGe can change, Factors like driving style, temperature, terrain, and climate control use can all affect range and efficiency. Fast acceleration and high speeds will drain the battery faster. Very cold weather can also reduce battery performance. Owners in colder areas should account for this in their range calculations, especially in winter. However, driving carefully in mild weather will usually lead to achieving or exceeding the EPA estimates. Remember to consult SOLTERRA MPG across all years for related data.

How it compares

For instance, the Kia Niro EV gets a combined rating of 113 MPGe, slightly better than the Solterra. The Hyundai Kona Electric gets 120 MPGe combined. The Nissan Ariya Venture+ FWD gets 111 MPGe. Although these differences seem small, they matter to buyers focused on maximizing efficiency and minimizing charging frequency. The Solterra, though, has standard all-wheel drive, which isn’t usually found in similar EVs without paying more. Subaru buyers value capability and confidence in tough conditions, and they often accept a small trade-off in efficiency to get all-wheel drive and Subaru’s reputation for reliability.

Tips to maximize efficiency

Preconditioning the battery while plugged in can greatly improve cold-weather range. Warming the battery using grid power instead of battery power means you’ll start with a battery at its best operating temperature. This helps during winter when cold batteries have less capacity.

Use regenerative braking modes well. The Solterra has different levels of regenerative braking, letting you control deceleration and energy recapture when lifting off the accelerator. Increasing regeneration can extend your range, mostly in city driving with frequent stops. Try the different settings to find the one that suits you best.

Keep energy-intensive accessories to a minimum. Climate control systems, especially heating, can use lots of energy in electric vehicles. Use seat heaters and steering wheel heaters to stay warm, as they use less energy than heating the whole cabin. Wear appropriate clothing to reduce your climate control needs.

Keep tires properly inflated. Underinflated tires increase rolling resistance, which hurts fuel efficiency, or energy efficiency here. Check tire pressures often and inflate them to the recommended levels on the tire placard. Proper inflation helps efficiency, handling, and tire life.

Plan routes carefully. When possible, choose routes that minimize elevation changes and avoid traffic. Driving uphill or sitting in traffic uses more energy. Using navigation systems to find the best routes can help you get the best range and reduce charging stops.
