The MG S9 PHEV: Everything You Need to Know About MG's 7-Seat Hybrid SUV

The upcoming MG S9 Plug‑in Hybrid is set to become MG’s largest and most practical SUV yet. Designed as a spacious family vehicle with a modern plug-in hybrid powertrain, the S9 combines strong performance, everyday efficiency and flexible interior space.

Positioned at the top of the MG range, this new seven-seat SUV has been built with families and long-distance drivers in mind, offering the versatility of a large SUV alongside electrified driving.

Here’s everything you need to know about the all-new MG S9 Plug-in Hybrid.

A True 7-Seat SUV

The MG S9 Plug-in Hybrid is designed to offer genuine seating for seven passengers, rather than the smaller “5+2” layouts often found in many SUVs. The spacious cabin makes it suitable for larger families or drivers who regularly travel with multiple passengers.

With a body length of around 4.98 metres and a 2.92-metre wheelbase, the S9 provides generous room across all three rows of seating.

The second-row seats can slide forward to help balance passenger space and luggage capacity depending on your needs.

This flexibility makes the S9 ideal for:

• Family road trips

• School runs and everyday driving

• Carrying larger groups comfortably

• Transporting bulky items when seats are folded

Flexible Boot Space

Practicality is a major focus of the S9’s design, and the large SUV offers adaptable cargo space depending on how the seats are configured.

Boot capacity includes:

• 203 litres with all seven seats in use

• 517 litres with the third row folded

• Up to 1,052 litres with both rear rows folded

This flexible layout allows the vehicle to switch easily between carrying passengers and transporting larger loads.

Plug-in Hybrid Efficiency

The MG S9 uses a plug-in hybrid powertrain, combining a petrol engine with an electric motor to improve fuel efficiency and reduce emissions.

Plug-in hybrid vehicles allow drivers to complete shorter journeys using electric power while still retaining the convenience of a petrol engine for longer trips.

This setup provides several benefits:

• Lower fuel consumption on daily drives

• Reduced emissions during electric driving

• The ability to recharge the battery at home or public chargers

• Petrol backup for longer journeys

Plug-in hybrid technology is becoming increasingly popular among drivers who want some of the advantages of electric vehicles without committing to a fully electric car.

Modern Interior and Technology

Inside the cabin, the S9 features a modern and technology-focused dashboard design.

A dual 12.3-inch digital display combines the central infotainment touchscreen and the driver’s digital instrument display within a single panel.

Physical shortcut buttons sit beneath the screen, allowing drivers to quickly access key controls without relying solely on the touchscreen.

The interior design follows the premium style seen in newer MG models, with high-quality materials and a clean layout aimed at making long journeys more comfortable.

Safety and Driver Assistance

Safety is also a key focus for the MG S9 Plug-in Hybrid.

The SUV has already achieved a five-star safety rating in Euro NCAP testing, demonstrating strong performance across several crash-safety categories including adult and child occupant protection.

The vehicle also includes advanced driver-assistance technologies designed to support the driver and improve safety during everyday driving.

A New Flagship SUV for MG

The MG S9 Plug-in Hybrid represents an important step for the brand, introducing its first seven-seat SUV and expanding its range of electrified vehicles.

With its spacious cabin, hybrid efficiency and modern technology, the S9 is designed to appeal to drivers who need the practicality of a large SUV while also wanting the benefits of electrified driving.
