MG HS I (2018 – 2021)

Reliability score : 7.6/10

The first-generation MG HS (before its major facelift) marks a crucial step in the reconquest of international markets by the British brand, now under the umbrella of the Chinese giant SAIC Motor. Positioned as a family compact SUV (C-segment), it relies on an unbeatable price-to-equipment ratio, a surprisingly neat interior presentation (soft-touch materials, sports seats on high trims), and generous roominess. While it does not shine with its driving dynamics — clearly favoring ride comfort —, it offers a rational alternative to the European and Asian leaders. In Europe, it was first introduced as a plug-in hybrid version (EHS) before offering 100% internal combustion gasoline engines. Overall mechanical reliability is reassuring, largely supported by a 7-year manufacturer's warranty, al

🎯 Verdict

The MG HS (2018-2021) is a pragmatic choice par excellence. If you are looking for a comfortable, well-equipped, and affordable family SUV, it perfectly fulfills its contract. The 1.5 T-GDI gasoline engine is the most rational choice: it is mechanically sound, derived from a proven parts bin (SAIC/GM), and avoids the complexity of the plug-in hybrid version. Buying used is all the more recommended as the majority of models still benefit from the 7-year manufacturer's warranty. However, you will have to accept a temperamental multimedia system and slightly higher fuel consumption than European benchmarks. Favor a model with a clear maintenance history that has received all software updates at the dealership.
