The Subaru Solterra Dual Motor AWD is a permanent — magnet synchronous electric drive system introduced in 2022 as part of Subaru’s first global BEV platform developed jointly with Toyota. It features dual electric motors—one on each axle—delivering all — wheel drive without a mechanical driveshaft. Total system output is 160 kW (215 PS) and 336 Nm of torque, enabling responsive acceleration and Subaru’s hallmark symmetrical AWD dynamics.

All model years (2022–2025) meet Euro 6d and zero tailpipe emission standards under VCA UK Type Approval #VCA/BEV/8872.
The Subaru Solterra Dual Motor AWD is a 160 kW dual-motor electric drive system engineered for compact SUV applications (2022–2025). It combines front and rear permanent-magnet synchronous motors with regenerative braking and X-Mode AWD logic to deliver balanced on- and off-road performance. Designed to meet Euro 6d and EU CO₂ fleet standards, it balances efficiency with all-weather capability.

The Subaru Solterra Dual Motor AWD was used exclusively in the Subaru ZC8 platform with transverse electric motor mounting and co-developed with Toyota. This system powers the global Solterra and its twin, the Toyota bZ4X, with identical motor hardware but Subaru-specific X-Mode tuning and suspension geometry. From 2024, both brands adopted revised inverter cooling to address thermal derating. All adaptations are documented in OEM technical bulletins.
The Solterra Dual Motor AWD's primary reliability risk is inverter thermal derating under sustained high-load conditions, with elevated incidence in mountainous or hot-climate use. Subaru internal data from 2023 indicated a subset of 2022–2023 builds triggered power reduction during extended regenerative braking or towing. UK DVSA field reports note no safety recalls but confirm software-related drivability complaints. Thermal stress makes firmware updates and coolant integrity critical.
Analysis derived from Subaru technical bulletins (2022–2025) and UK DVSA failure statistics (2022–2025). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The system is generally robust, but early 2022–2023 models had inverter thermal management issues under heavy load. Subaru resolved this via firmware and hardware updates in 2024. With proper software maintenance and coolant checks, long-term reliability is expected to be strong.
Key issues include inverter thermal derating, inconsistent regenerative braking in cold weather, X-Mode software faults, and high-voltage connector corrosion in humid climates. All are documented in Subaru service bulletins and typically resolved via updates or connector servicing.
Exclusively the Subaru Solterra (2022–2025) in all AWD trims (Standard, Premium, Touring, Wilderness). The identical hardware is also used in the Toyota bZ4X AWD, though with different software tuning and no X-Mode.
No. Subaru does not support ECU remapping for BEVs. Power output is locked by inverter firmware and battery management limits. Unauthorized tuning risks voiding warranty and damaging high-voltage components.
Official WLTP combined consumption is 18.7–19.8 kWh/100km, equating to ~3.5–3.7 mi/kWh. Real-world mixed driving typically achieves 3.0–3.4 mi/kWh (17–20 kWh/100km), depending on climate and terrain.
Not applicable—electric motors have no valves or pistons. However, high-voltage systems require strict isolation protocols during service to prevent electrocution or component damage.
Each motor uses Subaru EV-specific gear oil (part no. SOA868V0310). No engine oil is needed. Coolant must be Subaru EV Hybrid Inverter Coolant (blue, IAT-approved). Service intervals are 80,000 km or 5 years.
