The MG 1.5L eGT is a 1,498 cc, inline — four, turbocharged petrol engine developed by SAIC Motor for use in MG's modern passenger vehicles. Produced from 2020 onwards, it features direct fuel injection, dual overhead camshafts (DOHC), and a low — inertia turbocharger to balance responsiveness and efficiency. In its standard tune, it produces 125 kW (170 PS) and 250 Nm of torque, enabling strong mid — range performance in compact and mid — size models.

All production years 2020–present meet Euro 6d emissions standards .
The MG 1.5L eGT is a 1,498 cc inline-four turbo-petrol engineered for compact SUVs and fastback sedans (2020–present). It combines direct injection with a low-inertia turbocharger to deliver responsive mid-range acceleration. Designed to meet Euro 6d standards, it balances performance and emissions compliance for urban and highway use.

The MG 1.5L eGT was used across MG's SSA platform with transverse mounting and shared architecture with Maxus for commercial derivatives. This engine received platform-specific adaptations-shorter intake manifolds in the MG5 and hybrid integration in the HS PHEV-and from 2022 the updated HS facelift adopted revised ECU mapping for improved throttle response, creating software compatibility limits. Partnerships enabled Maxus to use the base engine in the G50 van. 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.

The most common questions about engine codes, what they mean, how to find them and how this database works
The 1.5L eGT is generally reliable when maintained properly, though early 2020–2021 models show higher rates of intake carbon buildup. Later ECU updates have improved fuel management. Using 95 RON or higher fuel and adhering to 15,000 km oil change intervals significantly reduces risks. No widespread mechanical failures have been reported, but cooling system maintenance is essential.
The most common issues are intake valve carbon deposits, turbo boost control faults, and cooling system airlocks. Secondary concerns include degraded engine mounts in PHEV variants and occasional lambda sensor failures. These are documented in SAIC service bulletins and addressed through software updates and preventive maintenance routines.
The 1.5L eGT engine is used in the MG HS (2020–present), including the PHEV variant, and the MG5 (2021–present). It is also found in the Maxus G50 van (2020–2023). All models feature transverse mounting and meet Euro 6d emissions standards. The HS PHEV integrates the engine with an electric motor for combined output.
Aftermarket ECU tuning is common on the 1-5L-EGT platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
In the MG HS, real-world consumption averages 7.8–9.2 L/100km (30–36 mpg UK) in mixed driving. Highway efficiency improves to ~6.5 L/100km (43 mpg UK). The MG5 achieves slightly better economy due to lower weight. Performance varies significantly with driving style and fuel quality, especially in urban conditions.
Yes, the 1.5L eGT is an interference engine. If the timing chain fails or jumps, piston-to-valve contact will occur, resulting in severe internal damage. While the chain is designed for the life of the engine, any abnormal noise from the timing cover should be investigated immediately to prevent catastrophic failure.
SAIC specifies SAE 5W-30 oil meeting SAIC C2/C3 standards (backward compatible with ACEA C1-00). Use only low-ash, high-detergent synthetic oil to protect the turbocharger and direct injection system. Change intervals are 15,000 km or 12 months, whichever comes first, under normal conditions.
