MG has made a bold entry into the large SUV market with the introduction of its first-ever seven-seat model, the MG S9 PHEV. Stretching nearly five metres, the S9 is notably larger than established rivals such as the Hyundai Santa Fe, yet it arrives with a competitive starting price of £34,205. This undercuts not only the Santa Fe but also the Kia Sorento and Peugeot 5008, positioning the S9 as a value-driven option within the plug-in hybrid segment.
To assess whether MG’s latest offering delivers genuine value or sacrifices too much in the pursuit of affordability, the S9 underwent a comprehensive road test with What Car. Key areas of focus included interior space, practicality, technology, and driving dynamics.

One of the S9’s headline features is its capacious interior. With all seats in place, the model boasts a substantial 1026-litre boot, providing ample room for luggage even with all three rows occupied. The rearmost seats were also tested for adult comfort, revealing adequate space for shorter trips, though longer journeys may prove less comfortable for taller passengers.
Underpinning the S9’s appeal is its plug-in hybrid powertrain, which offers an official electric-only range of 62 miles—a figure that exceeds many rivals in the segment. The regenerative braking system, however, may require an adjustment period for drivers unfamiliar with its operation, as its calibration differs from that of more conventional setups.

On the road, the S9’s driving manners were scrutinised, with particular attention paid to ride comfort, handling, and overall refinement. The interior quality and technology features were also evaluated to determine if MG’s latest SUV meets the expectations set by its more expensive competitors.
The MG S9 PHEV, with its generous equipment levels and aggressive pricing, poses a significant challenge to established players in the large SUV market. While it delivers impressive practicality and electric range, potential buyers will need to weigh these strengths against the nuances of its driving experience and interior finish.
