Summary
The MG S9 – or MGS9 PHEV – is a seven-seat plug-in hybrid SUV and the largest offering in the MG UK range at the time of its arrival in Spring 2026.
Joining a growing large plug-in hybrid category that already includes the Hyundai Santa Fe and Mazda CX-80, as well as keenly-priced Chinese newcomers like the Omoda 9 and Chery Tiggo 9, the MG S9 is both longer and taller than the brand’s HS SUV.
“Space in the rear seats, which is the main reason you’d choose it over the HS, isn’t particularly great”, says Alastair Crooks of Auto Express, however adding that the SUV represents “extraordinary value for money.”
While the large SUV is set to arrive in British showrooms imminently, only a select few in the British motoring media has got behind the wheel of the S9 at the time of writing. That means we have no Expert Rating score to display at the moment.
We will update this page with more information and reviews, as well as safety and running cost data, as soon as those are available. Check back soon!
