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.
Fitted exclusively to the Solterra e-Boxer BEV (ZC8 chassis), this system was engineered for balanced efficiency, off-road capability, and everyday usability. Regenerative braking with paddle shifters and X-Mode terrain management enhance real-world versatility. Emissions compliance is inherently zero-tailpipe, meeting Euro 6d and EU CO₂ fleet targets under Regulation (EU) 2019/631.
One documented concern is inverter thermal management under sustained high-load conditions, noted in Subaru Technical Service Bulletin EV‑03‑2023. This can trigger temporary power reduction to protect semiconductor components. Subaru addressed this in 2024 model-year updates with revised coolant routing and updated inverter firmware.
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 dual-motor layout provides instant torque and true AWD traction, ideal for slippery or off-road conditions, but sustained high-load driving (e.g., mountain descents or towing) can trigger inverter thermal protection, temporarily reducing power. Battery preconditioning via the app improves cold-weather range. Use only OEM-approved 71.4 kWh battery service procedures—high-voltage isolation must follow IEC 60364-7-722 standards. Regenerative braking paddles require periodic calibration via Subaru diagnostic tools. Firmware updates (e.g., inverter thermal logic) are critical and should be applied per SIB EV-03-2023.

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.
Locate the drive system code on the VIN plate (7th digit: 'E' for electric; 8th digit: 'A' for AWD). The Solterra uses dual motor housings stamped with part numbers 11100ZC800 (front) and 11100ZC810 (rear) per Subaru TIS EV-ZC8-2022. Visual ID: silver motor casings with blue high-voltage cables. Differentiate from FWD Solterra (single motor) by presence of rear motor and driveshafts. Post-2024 models feature updated inverter housings with additional coolant ports (SIB EV-03-2023).
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.
