SmartGrandads View
The MG 4X is the perfect entry point for families transitioning from petrol to electric who need more cargo space than a standard hatchback offers. It’s an ideal “everyman” EV—practical, affordable, and well-equipped.
While it competes with the BYD Atto 3 and GWM Ora, its combination of design and price makes it a potential global bestseller as it rolls out to international markets throughout 2026 and 2027.
