The MG4 EV is the first vehicle to be based on SAIC's battery-electric Modular Scalable Platform.
The MG4 EV is claimed to have a 50:50 weight distribution and a low centre of gravity of 490 mm (19.3 in) for superior handling.MG also engineered a thinner and flatter battery compared to typical battery electric vehicles with its "One Pack" battery system (called Rubik's Cube battery system in China). The battery is only 110 mm (4.3 in) thick for the smallest capacity, which reduces the height of the car. The "One Pack" battery is also designed to be swappable.
