The 2024 Subaru Solterra Limited and Touring AWD achieve 102 MPG combined, a number that is excellent for an all-electric vehicle geared toward outdoor enthusiasts who want lower fuel costs. These buyers prioritize Subaru’s reliable all-wheel-drive system and commitment to responsible manufacturing, even as they minimize their carbon footprint. They’re not necessarily chasing the longest range or the fastest acceleration; instead, they’re seeking a capable and practical EV that aligns with their active lifestyles and values.

City and highway performance

The EPA breaks down the Solterra’s efficiency further, showing 111 MPG in the city and 93 MPG on the highway. The city MPG reflects the regenerative braking system’s effectiveness in stop-and-go traffic, recouping energy during deceleration. Highway MPG is still respectable, but energy consumption increases at higher speeds due to aerodynamic drag and the constant power demand of maintaining momentum. These figures suggest superior performance in urban areas between adventures, with reasonable efficiency on longer drives to trailheads and campsites. This is useful for the Solterra’s target demographic, those who value weekend adventures and exploring off the beaten path.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2024 Subaru Solterra Limited/Touring AWD at $750. This is based on driving 15,000 miles per year and using the national average electricity price. Individual electricity costs vary significantly depending on location and charging habits. Home charging during off-peak hours can substantially reduce this cost, while relying solely on public charging stations may increase it. Regardless, $750 represents a dramatic potential savings compared to gasoline-powered SUVs, directly impacting the long-term cost of ownership.

Real-world expectations

The EPA provides standardized testing, but real-world EV efficiency depends heavily on driving style, ambient temperature, and terrain. Aggressive acceleration and high speeds deplete the battery faster, while gentle driving and warmer weather extend the range. Hills and off-road conditions also impact efficiency. Owners report that carefully managing climate control and optimizing driving habits can get them closer to the EPA estimates, but expect some variation based on individual use patterns. Unlike gasoline cars, which get worse mileage in the city, EVs often meet or exceed their mpg rating in city driving due to regenerative braking.

How it compares

Compared to its direct competitor, the Toyota bZ4X (with which it shares a platform), the Solterra’s efficiency is nearly identical. The all-wheel-drive bZ4X XLE achieves a combined 104 MPGe. The Hyundai Kona Electric boasts an impressive 116 MPGe combined (132 city/100 highway), making it a more efficient EV overall, though it lacks the Solterra’s standard all-wheel drive. The Kia Niro EV comes in at 113 MPGe Combined. These comparisons highlight the Solterra’s positioning within the EV landscape: it prioritizes all-weather capability and SUV practicality over efficiency, appealing to a specific segment of buyers who value those attributes. Review SOLTERRA MPG across all years for a holistic view of this vehicle’s efficiency.

Tips to maximize efficiency

Preconditioning the battery while plugged in is beneficial for maximizing range in cold weather. Heating the battery pack to its optimal operating temperature before departing ensures that less energy is devoted to warming it during the drive itself. This is particularly useful for those living in cold climates where efficiency can be drastically reduced.

Gentle acceleration and consistent speeds conserve energy. EVs are known for their instant torque, but resist the urge to aggressively accelerate at every opportunity. Maintaining a steady speed, particularly on the highway, has a major impact on battery life and overall EV efficiency. This applies to the Solterra even more so than to front-wheel-drive EVs due to all-wheel-drive’s natural efficiency drawback.

Use regenerative braking effectively. The Solterra offers adjustable regenerative braking settings. Experiment with different levels to find the one that best suits your driving style. Anticipate stops and starts to maximize energy recapture and minimize the need for traditional friction braking, helping to extend range and conserve electricity.

Consider using “Eco” mode. Eco mode typically adjusts throttle response and other vehicle settings to prioritize efficiency. While it may slightly reduce performance, the trade-off can be worthwhile, especially on longer trips or in situations where maximizing range is critical. It’s a great way to remain efficient behind the wheel.

Check tire pressure regularly. Properly inflated tires reduce rolling resistance, improving overall efficiency. Consult the sticker on the driver’s side doorjamb for the recommended tire pressure for your Solterra. Maintaining proper inflation is a simple yet effective way to squeeze more miles out of each charge. You can find all Subaru fuel economy data on our website.
