The new MG4, the world’s first mass-produced EV with a semi-solid-state battery, has quickly become a bestseller in China, with the 100,000th model rolling off the production line in just eight months.

After launching the all-new MG4 at the Chengdu Auto Show last August, SAIC Motor deemed it “the world’s first mass-produced semi-solid-state” electric vehicle.

In just eight months, SAIC announced that the 100,000th model rolled off the production line, which, according to the company, is “a new record for the fastest-selling pure electric hatchback.”

The MG4 has consistently ranked as a top seller with over 10,000 models sold for the past seven months, ranking in the top three in its class. In April, sales reached a record of over 13,000 units.

The new MG4, sold as the MG4 Urban in Europe, the UK, and other overseas markets, is available in five trims, including a semi-solid-state edition. Prices start at just 68,800 yuan ($10,000), while the semi-solid-state model costs 102,800 yuan ($14,500).
