On November 21, at the 2025 Guangzhou International Auto Show, which opened that day, MG officially launched the world's first mass-produced model equipped with a semi-solid battery - the new MG4 Semi-Solid Battery Safety Edition, and announced that deliveries will begin in December. The new car is priced at 99,800 yuan.
This pricing surprised many. After the press conference, when asked by the media why they were using semi-solid-state batteries, considered a "high-end premium technology" in a 100,000 RMB-level vehicle, Chen Cui, General Manager of SAIC Passenger Vehicle's MG Brand Business Unit, pointed out, "This year is the first year of MG's new century, the first year of MG's full commitment to new energy vehicles. We are willing to offer our utmost sincerity to consumers. We hope our products can be provided to more customers, and naturally, we will make some concessions on profitability."

Chen Kai, general manager of Qingtao Power, added that SAIC and Qingtao have achieved controllable battery costs through joint R&D and capacity building: "With the deep integration of the two parties, the manufacturing cost of this battery cell does not have cost pressure while meeting the requirements of this model."
Chen Kai further revealed that the two parties have already cooperated on multiple brands and multiple technology routes in the field of batteries: "It's not just MG... Some have high energy density, some have fast charging performance, and some will bring customers a better user experience."
Chen Cui also revealed that another important consideration for semi-solid-state battery models is that, in addition to safety, MG aims to achieve "equal accessibility between the north and south." He stated that current new energy vehicles are not very user-friendly for northern users, especially during colder seasons. Some new energy vehicles cannot even be charged, and at temperatures of -20℃ or -15℃, they cannot output their full power.
Does this mean that customers in northern China can only drive gasoline-powered cars and can't use new energy vehicles? MG is preparing to change that. According to the company, extreme cold weather testing will be conducted in Mohe in December to demonstrate MG's ability to offer "equal access to vehicles in both the north and south."
Looking ahead, Chen Cui stated that MG has planned to launch 13 new energy vehicle models by the end of 2027, "and not a single one will be delayed." He emphasized, "Achieving higher sales targets is not important; what's important is whether we can continue to do so in the next 100 years. That's the most impressive thing."
