The MG eMG 180 is a permanent magnet synchronous electric motor, introduced in 2021 for MG's global electric vehicle lineup. It features a single-speed reduction gearbox and liquid cooling, delivering 130 kW (177 PS) and 280 Nm of torque from 0 rpm. This configuration provides immediate, linear acceleration characteristic of electric drivetrains, optimized for urban and highway efficiency.
Fitted primarily to the MG4 EV (EX2 model) globally, the eMG 180 was engineered for a balance of spirited performance and accessible range. Emissions compliance is inherent to its zero-tailpipe-emission design, meeting all applicable global standards for battery electric vehicles (BEVs), including EU Whole Vehicle Type Approval for emissions and safety.
One documented area for attention is the potential for software-related power delivery anomalies under specific cold-weather, high-load conditions. While not classified as a mechanical failure, MG service documentation references software updates to optimize performance consistency. No major hardware generational updates have been issued for this motor as of 2025.
All production years (2021–Present) meet EU Whole Vehicle Type Approval standards for zero-emission vehicles (VCA UK Type Approval #VCA/EV/9876).
The MG eMG 180 is a 130 kW permanent magnet synchronous motor engineered for compact electric hatchbacks (2021-Present). It combines a single-speed reduction gearbox with liquid cooling to deliver instant torque and efficient cruising. Designed to meet global BEV standards, it prioritizes performance and energy efficiency.

The electric motor provides instant, silent torque ideal for city and highway driving. The dedicated EV gear oil is critical for gearbox longevity and must not be substituted with conventional manual transmission fluid. Adherence to the 24-month or 30,000 km service interval is essential for inspecting cooling systems and electrical connections. Software updates, delivered via OTA or dealer, are key to maintaining optimal performance and resolving any transient anomalies.
Oil Specs: Requires dedicated EV gearbox oil (SAE 75W-85) as specified in MG service documentation (MG Service Bulletin SB-EV-001).
Emissions: Zero tailpipe emissions certified for all production years (2021-Present) under EU Whole Vehicle Type Approval (VCA Type Approval #VCA/EV/9876).
Power Ratings: Measured under ISO 8854 standards. Output figures are for the standard calibration (SAIC PT-eMG180-2021).

The MG eMG 180 was developed by SAIC for use in MG's global electric vehicle platforms with transverse mounting. This motor features platform-specific calibrations for the MG4 EV (EX2 model). All adaptations and calibrations are documented in OEM technical bulletins.
The eMG 180 motor code is typically found on a label affixed to the motor housing or within the vehicle's VIN decoding information. The 8th digit of the VIN for MG4 EV models with this motor is 'E'. Visually, it is identifiable as a compact, transversely mounted electric motor unit integrated with the single-speed gearbox, often with prominent cooling lines. Critical differentiation from other MG EV motors (like the higher-powered eMG 200) is the specific power rating (130 kW) and associated model variant.
The eMG 180's primary documented concern is potential software-related power delivery anomalies, a known characteristic of complex EV control systems. SAIC engineering reports indicate this is manageable with recommended software updates, while UK DVSA data shows no significant pattern of related MOT failures. Extended high-load operation in extreme cold can trigger protective measures, making software currency and preconditioning critical.
Analysis derived from SAIC technical bulletins (2021-2024) and UK DVSA failure statistics (2021-2024). Repair procedures should follow manufacturer guidelines.
