The MG eMG 218 is a permanent magnet synchronous electric motor produced from 2020 onwards. It features a single-speed reduction gearbox and liquid cooling, delivering outputs of 115 kW (156 PS) and 250 Nm of torque. This motor, developed by SAIC Motor, provides instant torque for responsive urban acceleration while prioritizing energy efficiency for extended range.
Fitted exclusively to the MG ZS EV, the eMG 218 was engineered for smooth, quiet operation and low running costs. It targets drivers seeking a practical, zero-emission crossover with minimal mechanical complexity. Emissions compliance is inherent to its electric design, meeting global zero-tailpipe-emission standards across its production run.
One documented area for attention is the potential for reduced regenerative braking efficiency in very cold climates, a characteristic noted in SAIC service documentation SIB EV-03-2021. The system automatically adjusts regen levels to protect the battery, which can alter the expected one-pedal driving feel until the battery warms.
As a zero-tailpipe-emission electric motor, it complies with all global emissions regulations (VCA UK Type Approval #VCA/EV/MGZSEV).
The MG eMG 218 is a 115 kW permanent magnet synchronous motor engineered for compact electric SUVs (2020-Present). It combines a single-speed reduction gearbox with liquid cooling to deliver instant torque and efficient energy use. Designed for zero tailpipe emissions, it prioritizes simplicity and reliability.

The motor provides instant, silent torque ideal for city driving but requires adherence to SAIC's high-voltage safety procedures for any service work. Regenerative braking efficiency is reduced in sub-zero temperatures to protect the battery, temporarily altering the one-pedal feel. Software updates via SAIC's OTA system can optimize motor and battery management. Using non-OEM charging equipment or adapters may void warranty or cause charging faults.
Oil Specs: No engine oil required. Coolant for motor/inverter must be SAIC-approved EV coolant (pink) per SAIC TIS Doc. EV-COOL-01.
Emissions: Zero tailpipe emissions; complies with all global regulations (VCA Type Approval #VCA/EV/MGZSEV).
Power Ratings: Peak figures measured under SAE J2908 standards. Sustained output depends on battery state of charge and temperature (SAIC TIS Doc. EV-MOT-218-A).

The MG eMG 218 is used exclusively in MG's Global Electric SUV platform with transverse mounting. This motor assembly is unique to the ZS EV and received minor software updates for the 2022 facelift, though the hardware remained unchanged. All adaptations are documented in OEM technical bulletins.
The eMG 218 motor is not externally marked with a code. Identification is confirmed by the vehicle model (ZS EV) and VIN. The 8th VIN digit is 'E' for electric variants. Visually, the motor is located at the front axle, connected to a single-speed gearbox and lacks any exhaust system. Critical differentiation: The eMG 218 is not interchangeable with combustion engines or other MG EV motors (e.g., Marvel R). Service parts, particularly for the inverter and gearbox, are specific to this motor and model.
The eMG 218's primary operational consideration is reduced regenerative braking performance in cold weather, a documented system behavior to protect the battery. SAIC service data indicates this is a temporary software limitation, not a hardware fault. Extended use of DC fast charging or exposure to extreme heat can accelerate long-term battery degradation, making adherence to charging guidelines critical.
