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.
