Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
The powertrain designation is essential for software updates, service scheduling, and verifying charging capabilities. It is not the same as the VIN or trim level. This guide shows exactly where to find it - by model and configuration - using official Polestar and DVLA sources
A descriptive identifier (e.g., 'Dual Motor') used for service, software, and parts compatibility.
The 17-digit vehicle identification number that holds encoded vehicle and powertrain information.
The equipment package (e.g., 'Plus', 'Launch Edition') which does not define powertrain specifications.
Access Settings > System > Vehicle Information on the central Android Automotive display. The powertrain designation appears alongside software version and VIN.
The T8 designation is confirmed via the central Sensus display under Vehicle Status. Physical VIN plate on windscreen also encodes powertrain data.
Navigate to Settings > Vehicle > About on the Android Automotive interface. Powertrain details, battery capacity, and motor configuration are listed under Technical Specifications.
The powertrain type is visible in the Polestar mobile app under Vehicle Details, synced from the car's central system. Also check the V5C 'Propulsion Type' field.

A technical breakdown of Polestar's core powertrain systems including dual-motor AWD, battery thermal management, regenerative braking and Performance software with documented reliability impacts. All data sourced from Polestar Technical Documentation and EU Regulation (EC) No 715/2007
Polestar's dual-motor system uses independent front and rear electric motors to deliver instantaneous all-wheel drive traction, torque vectoring, and enhanced performance without mechanical differentials.
Each motor is controlled by a dedicated inverter. The vehicle control unit dynamically allocates torque between axles based on grip, driver input, and efficiency targets. Regenerative braking can be applied independently to each motor for optimised energy recovery.
Polestar 2 (2020)
300 kW combined, fixed torque split
Polestar 3 (2024)
360 kW, active torque vectoring
Select Dual Motor variants
+20 kW, sharpened response
Software calibration updates
Early OTA updates refined torque delivery
Inverter thermal management
Monitored via battery thermal system
Motor bearing wear
Long-term reliability data still emerging

All technical descriptions and performance data sourced from Polestar Product Technical Reports, Polestar Service Information, and EU Regulation (EC) No 715/2007 on vehicle type-approval.
Authoritative data on Polestar's global powertrain integration, assembly operations, and strategic partnerships. All figures sourced from Polestar Annual Reports, Sustainability Reports, and EU industrial compliance records.
Polestar vehicles are assembled at partner facilities with powertrain integration from specialised suppliers.
Polestar transitioned to 100% BEV production from 2022. Note the rapid scaling aligned with EU electrification targets and Geely Group investment.
Note: Polestar ceased PHEV production after Polestar 1 (2021). All subsequent models are battery-electric, aligned with EU 2035 ICE phase-out roadmap.
Strategic collaboration within Geely Holding Group. Polestar leverages Volvo's CMA/SPA platforms and T8 PHEV technology while developing independent BEV architecture and software.

The most common questions about engine codes, what they mean, how to find them and how this database works
Confirm the full engine designation using vehicle-specific manufacturer records and the engine marking. An engine serial number, a registration record and a marketed power badge are not automatically the same identifier. Match the VIN/build data and the installed engine before selecting parts or a replacement.
No. A factory-application reference and a replacement-interchange decision are different. Match the full engine designation, vehicle build data, emissions equipment, controls and relevant supplier/OEM information.
No. Records have different review states. Read the correction notice, source scope and application limits on the individual record. Missing technical fields must not be inferred from similar engine codes.
EngineCode.uk provides reference information about Polestar Powertrain Codes Database engines. It is operated by Engine Finders UK Ltd and also offers an optional replacement-engine enquiry service. Technical information can contain errors or omissions.
