MG S9 PHEV Overview: Generations, Specs, and Which Version to Buy

Overview of the MG S9 PHEV, a five-door plug-in hybrid SUV built since 2025, covering its single generation and the 231 hp 1.5 AT version.

The MG S9 PHEV is a five-door SUV produced from 2025 to the present, offered with a single 231 hp powertrain built around a 1.5-liter (1496 cc) engine, an automatic gearbox, and front-wheel drive. It suits drivers who want a family-sized SUV with strong combined output and a very low claimed fuel figure of 2.3 l/100km, without needing all-wheel drive or a wide trim ladder to choose from.

MG S9 PHEV generations

1 generation (2025–present)

The first and so far only generation of the MG S9 PHEV launched in 2025 and remains in production. It is offered exclusively as a five-door SUV with one modification: the 1.5 AT, rated at 231 hp, paired with an automatic transmission and front-wheel drive. The 1.5 AT (1 generation) accelerates from 0 to 100 km/h in 9.6 seconds and has a rated consumption of 2.3 l/100km, drawing on a 1496 cc engine as the combustion side of the plug-in hybrid system.

Because the lineup contains exactly one powertrain, the power range for the whole model is flat at 231 hp — there are no weaker entry versions and no stronger flagship variants to weigh against each other. Every MG S9 PHEV built since 2025 carries the same mechanical package, so generation-to-generation or engine-to-engine comparisons simply do not apply to this model yet.

Which MG S9 PHEV to buy

On the used market the situation is unusually simple: production only started in 2025, so any example you find is at most a year or so old and mechanically identical to a new car. There is no risk of accidentally buying an older generation or a weaker engine, because neither exists — the checklist reduces to the condition and history of the specific car.

Since the range contains a single 231 hp version, there is no dominated variant to warn against: the choice of the MG S9 PHEV is a choice of the model itself, not of a configuration within it.
