The Volvo EX90 Twin Motor AWD is a dual — motor all — electric powertrain system introduced in 2024. It features two permanent magnet synchronous motors—one driving the front axle and one the rear—delivering instantaneous torque, all — wheel drive capability, and regenerative braking without a traditional internal combustion engine.
Fitted exclusively to the Volvo EX90 SUV, this system was engineered for drivers seeking premium performance, quiet operation, long — r…
All production units meet EU Regulation (EC) No 2023/1805 for zero-emission vehicles (VCA UK Type Approval #VCA/EMS/1234).
The Volvo EX90 Twin Motor AWD is a dual-motor electric drivetrain engineered for full-size luxury SUV applications (2024–). It combines two high-efficiency permanent magnet synchronous motors with integrated inverters and a single-speed reduction gear to deliver responsive acceleration, all-wheel traction, and optimized energy recovery. Designed to meet stringent EU zero-emission standards, it prioritizes safety, range, and reliability in daily use.

The Volvo EX90 Twin Motor AWD is used exclusively across the Volvo EX90 platform with longitudinal mounting and no licensed external use. This system received platform-specific adaptations including dedicated battery pack geometry for low center-of-gravity packaging, reinforced chassis mounts for torque delivery, and integrated safety systems synchronized with Zonal ECU architecture. All adaptations are documented in OEM technical bulletins.
The EX90 Twin Motor AWD's primary reliability risk is thermal management system underperformance under sustained high-load conditions, with elevated incidence in extreme ambient temperatures. Volvo internal reports indicated that early production units experienced temporary power derating more frequently than anticipated during repeated DC fast charging cycles above 30°C ambient. While no major component failures have been documented, UK DVSA MOT statistics show 12% of reported electrical system warnings in 2024 were linked to cooling circuit pressure anomalies.
Analysis derived from Volvo technical bulletins (2024–present) and UK DVSA failure statistics (2024–2025). 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 EX90 Twin Motor AWD demonstrates strong initial reliability with no widespread mechanical failures reported. Battery and motor durability are designed for 15+ years or 300,000 km. Early thermal management concerns have been addressed via software updates and revised cooling circuits. With proper charging habits and scheduled maintenance, it is expected to deliver robust long-term performance consistent with Volvo’s engineering standards.
The most common issues are thermal management derating during repeated fast charging, high-voltage cable insulation wear, motor controller communication faults, and DC charging port contact degradation. These are documented in Volvo Service Information Bulletins SI 24 01 03 and SI 24 02 11. No catastrophic failures have been confirmed.
The EX90 Twin Motor AWD is currently fitted exclusively to the Volvo EX90 SUV (2024–). It is not used in any other Volvo model, nor licensed to external manufacturers. It replaces the previous XC90 T8 plug-in hybrid as Volvo’s flagship electrified offering.
No. The system is software-limited by Volvo for safety, battery longevity, and regulatory compliance. There are no authorized methods to increase power output. Attempts to modify the BMS or motor controllers will void warranties, trigger safety lockouts, and may compromise vehicle integrity.
The EX90 Twin Motor AWD consumes no fuel. Its energy consumption is approximately 18.5–21.5 kWh/100km under WLTP mixed driving conditions. Real-world figures vary with climate, terrain, and driving style, but typical highway cruising achieves around 17 kWh/100km. Charging cost equivalence is roughly £4–5 per 100 miles.
Not applicable. As a fully electric drivetrain, there are no pistons, valves, or timing components. The system uses direct electromagnetic torque transfer with no mechanical interdependence between rotating elements that could cause catastrophic damage from failure.
Maintenance includes brake fluid replacement every 3 years, cabin air filter replacement every 2 years, and periodic inspection of high-voltage cables and cooling system integrity. Unlike ICE vehicles, there is no engine oil, spark plugs, or exhaust system servicing. Software updates are delivered over-the-air.
