# This electric SUV has a semi-solid-state EV battery, and it will go on sale in a few days

After launching the first mass-produced EV with a semi-solid-state battery last year, SAIC Motor is following it up with the new MG 4X electric SUV. The new EV will go on sale in less than a week.

## The MG 4X is an EV SUV with a semi-solid-state battery

At the Chengdu Auto Show last year, SAIC launched the new MG4, deeming it “the world’s first mass-produced semi-solid-state” electric vehicle.

Deliveries began in China in December 2025, priced from 102,800 yuan ($14,500) for the semi-solid-state battery variant. The standard MG4 starts at just 68,800 yuan ($9,800).

All other MG4 variants are powered by either a 42.8 kWh or a 53.95 kWh lithium-iron phosphate (LFP) battery, providing CLTC ranges of 437 km (271 miles) and 530 km (330 miles), respectively.
