MG S9 review – a HUGE 7-seater for under £35k!

In our new MG S9 review, we test MG's first-ever 7-seat SUV! The new MG S9 PHEV is almost five metres long, meaning it's even bigger than a Hyundai Santa Fe. But with a starting price of just £34,205, it massively undercuts the Hyundai as well as the Kia Sorento and Peugeot 5008.

But is this budget-friendly plug-in hybrid actually worth your money? We put the S9 through its paces to find out if its a true bargain or a false economy.

In this video, we take a detailed look around the 2026 MG S9 to see exactly how much space there is inside this massive 7-seater. We check out the huge 1026-litre boot, explain the 62-mile official electric range, and decide if the S9's interior and driving manners are up to scratch.

We also climb into the rearmost seats to test third-row passenger space, and tell you why the regenerative braking system might take some getting used to.
