Third row: who fits?
Third row suitsChildren
Carwow rates seats six and seven as best for children, though acceptable for adults on short journeys, and notes that reclining the backrests costs headroom. Auto Express found the back row only suits small children, with knees pushed up high by the raised floor. A one-button fold and tilt middle seat makes getting in fairly easy, and Fleet World quotes 864mm of third-row legroom and 924mm of headroom from seat base to roof.

MG MGS9 verdict: pros and cons
Our verdict The MGS9 is a large plug-in hybrid SUV with seven seats as standard, five Euro NCAP stars and up to 62 miles of electric range. The third row is best for children, and there is no rapid charging.
Pros
- Seven seats and plug-in hybrid power on every car
- Five-star Euro NCAP rating (2025)
- Seven-year or 80,000-mile warranty
Cons
- Third row best for children
- No rapid charging
- No Isofix in the third row
Good to know
- The 24.7kWh battery gives up to 62 miles of WLTP electric range, but there is no rapid charging and a 7.4kW home wallbox needs about four hours for a full charge (Grange MG, Auto Express)
- Euro NCAP gave it five stars in 2025, scoring 84% for adult occupants, 85% for child occupants, 74% for vulnerable road users and 77% for safety assist (Euro NCAP)
- The 1.5-litre turbo petrol engine makes 142PS and the electric motor 231PS, for 299PS combined driving the front wheels (theevreport)
- MG covers the car for seven years or 80,000 miles and the high-voltage battery for eight years or 100,000 miles (Grange MG)
- Auto Express quotes 224bhp and 322 litres with seven seats up, whereas MG dealer data and carwow give 299PS (295bhp) and 332 litres (Auto Express, Grainger MG, carwow)
Practicality
At 4,983mm long and 1,967mm wide without mirrors (2,237mm with them), the MGS9 is a big SUV to park. It tows up to 2,000kg braked.
The 24.7kWh battery gives up to 62 miles of WLTP electric range, but there is no rapid charging; a 7.4kW home wallbox needs about four hours for a full charge, so a home charger matters more than usual. Compare it with other plug-in hybrid 7-seaters.
