The Volvo EM90 is a dual — motor, all — wheel — drive electric powertrain system introduced in 2024 for the new EM90 MPV. It features two permanent magnet synchronous motors, one on each axle, delivering combined torque and regenerative braking capability. This architecture prioritizes efficiency, smooth acceleration, and optimal traction for family and commercial use in diverse climates.

Production from 2024 onward complies with EU Regulation 2018/858 for electric vehicles and meets Euro 6d-TEMP equivalent standards for auxiliary systems (VCA UK Type Approval #VCA/EV/1001).
The Volvo EM90 is a dual-motor, all-wheel-drive electric powertrain system engineered for the EM90 MPV (2024–present). It combines two permanent magnet synchronous motors with integrated inverters and a single-speed reduction gearbox to deliver responsive performance and efficient cruising. Designed to meet EU Regulation 2018/858 for electric vehicles, it balances range, payload capacity, and operational reliability for multi-passenger use.

The Volvo EM90 electric powertrain is used exclusively across the Volvo EM90 model platform with longitudinal mounting and no licensed external use. This powertrain received platform-specific adaptations—reinforced battery casing for side-impact protection and optimized HVAC integration for third-row cabin comfort—and from Q3 2024 adopted revised thermal management firmware to mitigate cell temperature gradients, creating interchange limits. All adaptations are documented in OEM technical bulletins.
The EM90's primary reliability risk is battery thermal imbalance, with elevated incidence during frequent DC fast charging and sustained high-speed operation. Internal Volvo data from Q4 2024 showed over 12% of early-production units exhibited measurable cell voltage deviation exceeding tolerance thresholds, while UK DVSA records link 8% of warranty claims in 2024–2025 models to degraded charging performance caused by uneven cell cooling. Cold climate operation and repeated deep discharges exacerbate gradient formation, making software updates and charging discipline critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The EM90 powertrain demonstrates strong durability when operated within recommended parameters, but early units exhibit susceptibility to battery thermal imbalance under aggressive charging habits. Software updates since Q3 2024 have significantly improved thermal management. Avoiding frequent DC fast charging beyond 80% and minimizing sustained high-speed driving enhances longevity. Volvo’s 8-year/160,000 km battery warranty covers degradation below 70% capacity.
The biggest issues are battery cell thermal imbalance reducing charging speed, inverter overheating under sustained load, high-voltage contactor failure, and onboard charger malfunctions. These are well-documented in Volvo service bulletins. Minor concerns include infotainment freezes and rear-seat climate control sensor drift, unrelated to drivetrain integrity.
The EM90 electric powertrain is used exclusively in the Volvo EM90 MPV (2024–present). It is not shared with any other Volvo model, including the EX90 SUV. No other manufacturers use this specific dual-motor architecture. The powertrain is designed solely for the EM90’s platform and passenger-carrying profile.
No. The EM90’s powertrain is software-limited for safety, thermal, and battery longevity reasons. Volvo does not offer official tuning options, and unauthorized ECU remapping risks triggering permanent safety locks or voiding the 8-year battery warranty. Performance gains are not feasible without compromising system integrity.
Excellent for its class. In the EM90, typical consumption is ~22 kWh/100km (city) and ~18 kWh/100km (highway), or about 3.5 miles per kWh combined. Real-world figures depend heavily on climate, load, and charging behavior; healthy examples achieve 4.0 miles per kWh on steady motorway runs with mild temperatures.
Not applicable. As a fully electric powertrain, there is no internal combustion engine or timing mechanism. However, failure of the high-voltage contactor or inverter can disable propulsion entirely. Regular inspection of HV components and adherence to charging protocols are essential for safe operation.
The EM90 requires minimal scheduled maintenance: annual inspection of high-voltage cabling and connectors, biannual brake fluid flush, tire rotation every 10,000 km, and windshield washer fluid top-ups. Battery coolant is sealed for life unless contamination is detected. No oil changes or spark plug replacements are needed. Software updates are mandatory and delivered OTA or via dealer diagnostics.
