About the 2026 Subaru Solterra

The Subaru Solterra is a joint development between Subaru and Toyota (where it's sold as the bZ4X), bringing Subaru's legendary symmetrical all-wheel drive and outdoor-focused engineering to the EV market. 227 miles of range is modest, but Subaru's 4WD capability is genuine.

Advantages

✓Subaru Symmetrical AWD — engineered specifically for off-road and winter conditions

✓Familiar Subaru-ness with EyeSight driver assistance standard

✓Subaru's outdoor-brand identity and loyal following

✓Shared Toyota platform ensures engineering stability

Considerations

✗100 kW DCFC is slow — 10–80% takes approximately 56 minutes

✗227-mile range is the lowest of any new EV SUV in 2025

✗3.1 mi/kWh efficiency is average; the low range amplifies the gap vs. competitors

✗No single-motor/RWD version — AWD standard

Ideal Buyer

Subaru Outback and Forester loyalists who want AWD in an EV. Winter-climate buyers for whom Subaru AWD is a cultural requirement. Rural buyers who need genuine all-weather capability.

vs. Gas Equivalent

Direct EV equivalent of a Subaru Forester or Outback. Gas equivalent is approximately 28–30 MPG for the Subaru Outback.

EV Ownership in South Dakota

South Dakota has very low EV adoption due to rural geography and a small population. Sioux Falls and Rapid City are the primary markets. The state's low electricity rates make charging cheap for those who adopt EVs.

Incentives & Programs

South Dakota has no state EV incentive. Federal incentives apply. MDU Resources and Black Hills Energy offer standard rate structures. The state has no income tax, which makes the federal income tax credit the primary incentive.

Charging Infrastructure

I-90 has limited DCFC — primarily at major stops like Sioux Falls, Mitchell, Rapid City. The Black Hills area (Mount Rushmore, Badlands) is improving. Long gaps exist on north-south routes.

Grid & Energy Source

South Dakota's grid is approximately 40% hydro (Missouri River dams), 30% wind, and 20% coal. The hydro and wind combination makes South Dakota's EV charging relatively clean, similar to neighboring North Dakota in wind characteristics.

South DakotaElectricity Rates & EV Savings

The average residential electricity rate in South Dakota is $0.13/kWh, which is below the national average of $0.17/kWh. With a gas price of $3.50/gallon, South Dakota ranks as a favorable state for EV ownership.

Cold weather reduces EV range by 20–40% as the battery heats itself and the cabin. Use scheduled departure to pre-heat on shore power before driving. Your Subaru Solterra's 72 kWh battery provides up to 227 miles of EPA-rated range. Real-world range may vary by 10–30% depending on temperature, speed, and terrain.

Tips for Charging Your Subaru Solterra in South Dakota

South Dakota's cold climate and charging infrastructure have specific implications for Subaru Solterra owners. Here are practical tips to maximize range and minimize charging costs in this state:

I-90 in South Dakota has very long stretches between exits — always charge fully at Mitchell or Murdo before continuing.

Rapid City is the key charging hub for Black Hills/Badlands visits — arrive with sufficient range for touring.

South Dakota winters are severe (-20°F in January) — expect 40–50% range loss in deep winter months.

The hydro + wind grid makes SD EV charging cleaner than the Midwest average.
