The Hyundai E — GMP (Electric — Global Modular Platform) motor is a permanent magnet synchronous electric motor integrated into Hyundai Motor Group’s dedicated EV architecture. It features a hairpin — wound stator, oil — cooled inverter, and an integrated 7 — in — 1 power electronics unit. In standard rear — wheel — drive form it delivers 168–225 kW (228–305 PS) with torque between 350–605 Nm, enabling 0–100 km/h in as little as 5.2 seconds.
Fitted to models such as the IONIQ 5,…

All E-GMP motor applications (2021–present) are classified as zero-emission vehicles under Euro 6d and meet UN Regulation No. 100 Rev. 3 for electric safety .
The Hyundai E-GMP motor is a permanent magnet synchronous electric motor engineered for premium electric vehicles (2021–present). It combines hairpin stator winding with direct oil cooling and an integrated 7-in-1 power electronics unit to deliver high continuous power output and ultra-fast charging capability. Designed as a zero-emission propulsion system, it meets UN R100 and Euro 6d (ZEV) standards while enabling 800V architecture operation.

The Hyundai E-GMP Motor is used across Hyundai Motor Group's E-GMP platform with rear or dual-motor layouts and no external licensing. This motor received platform-specific calibrations—revised torque curves in the IONIQ 6 for efficiency and enhanced cooling in the Kia EV6 GT for performance—while maintaining core architecture. All variants share the 800V SiC inverter and oil-cooling system. All adaptations are documented in OEM technical bulletins.
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.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.
Analysis derived from Hyundai technical bulletins (2021–2025) and UK DVSA zero-emission vehicle monitoring data (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
Yes. The E-GMP motor has demonstrated exceptional reliability with minimal reported failures through 2025. Its oil-cooled design and SiC inverter enhance durability under load. No routine maintenance is needed for the motor itself, though periodic inspection of cooling fluids is recommended for vehicles used in extreme conditions.
Issues are rare but include inverter overtemperature warnings (due to low motor oil), 12V battery drain from infrequent use, regenerative braking calibration loss after resets, and high-voltage connector corrosion if improperly serviced. All are addressed in Hyundai TSB‑EV‑009 and related bulletins.
The E-GMP motor powers the Hyundai IONIQ 5 (2021–present), IONIQ 6 (2022–present), Kia EV6 (2021–present), and Genesis GV60 (2022–present). All are zero-emission vehicles built on Hyundai Motor Group’s dedicated 800V electric platform.
Limited tuning potential. The motor and inverter are tightly integrated with safety systems. While some third parties offer ECU remaps for modest gains (~5–10%), Hyundai does not support modifications, and doing so may void the 8-year/160,000 km powertrain warranty.
Efficient for an EV. In an IONIQ 5 Long Range RWD, expect 380–480 km (WLTP: 507 km) depending on temperature and driving style. Highway driving at 110 km/h yields ~400 km; city driving can exceed 500 km due to regenerative braking. Cold weather (<5°C) reduces range by 20–30%.
Yes, but infrequently. The motor uses a dedicated oil circuit for cooling and lubrication. Hyundai recommends inspection every 40,000 km and replacement only if degraded. Use only Hyundai EV Motor Oil (P/N 00231‑21000)—standard fluids will damage the system.
Ultra-fast. Using a 350 kW DC charger, E-GMP vehicles charge from 10% to 80% in approximately 18 minutes. The 800V architecture enables this speed, and the system is backward-compatible with 400V chargers via an onboard voltage converter.
