Quick Highlights:SAIC MG starts deliveries of MG4 with semi-solid-state battery in China, world’s first mass-produced EV with this tech.Pricing starts at ¥68,800 (about ₹8,80,000) for standard versions and ¥102,800 (about ₹13,07,000) for the semi-solid-state battery model.The semi-solid-state battery reduces liquid electrolyte to 5%, boosting safety and cycle life.MG4 delivers up to 530 km CLTC range and features advanced tech including Qualcomm Snapdragon 8155 and large infotainment displays.SAIC Motor’s MG brand has begun deliveries of the all-new MG4 electric hatchback equipped with a semi-solid-state battery, a milestone in EV development as the company calls it the “world’s first mass-produced” vehicle with this next-generation battery technology. With competitive pricing and modern features, the MG4 is positioned to make waves in China’s booming EV market and potentially influence global EV affordability and safety standards.MG4 Launch: A New Era With Semi-Solid-State BatterySAIC MG first unveiled the all-new MG4 at the Chengdu Auto Show in August, promoting it as the first mass-produced EV to incorporate semi-solid-state battery technology . This advancement represents a significant step beyond conventional lithium-ion batteries by dramatically reducing the amount of liquid electrolyte used — down to just 5 percent — while integrating semi-solid components that support higher energy density and improved safety.The key innovation lies in lowering the risk of combustion and enhancing the battery’s cycle life compared with traditional liquid-electrolyte batteries. In recent independent needle penetration tests , the semi-solid-state battery showed remarkable performance, producing no smoke, fires, or explosions after two hours , a result SAIC MG said exceeds current industry standards by 20 percent.Price and Conversion: China to IndiaThe new MG4 lineup is available across multiple trims, with pricing structured to appeal to a range of buyers:Comfort, Ease, Freedom trims with the smaller 42.8 kWh battery start at ¥68,800 , approximately ₹8,80,000 (using an exchange rate of 1 CNY ≈ ₹12.8).The Smart version with a larger 53.95 kWh battery delivers more range and includes more advanced tech features.The semi-solid-state “Secure” edition is priced at ¥102,800 , roughly ₹13,07,000 under the same conversion assumption.These figures illustrate how SAIC MG is positioning the MG4 as a high-value offering in the EV segment, with even the most advanced battery version priced well below many competitors.Performance and RangeMG4 models are offered with two battery options:42.8 kWh LFP battery: Provides up to 437 km (271 miles) of CLTC driving range.53.95 kWh battery: Delivers up to 530 km (330 miles) of CLTC range.The semi-solid-state variant uses the 53.95 kWh semi-solid manganese-based lithium-ion battery , also rated for 530 km under the CLTC cycle, which tends to reflect optimistic but useful benchmarks for comparing EV range.All MG4 versions feature a single front-mounted PM motor delivering 120 kW (161 hp) and 250 Nm of torque. Fast charging capability lets the battery recharge from 30% to 80% in about 20 minutes using DC fast chargers, competitive with current mainstream EV standards.Size and Design ComparisonThe MG4’s compact dimensions make it directly comparable with popular small electric hatchbacks like the BYD Dolphin . With a length of 4,395 mm , width of 1,842 mm , and height of 1,551 mm , combined with a 2,750 mm wheelbase , the MG4 delivers an efficient footprint for urban and suburban driving while maximizing interior space.Tech and Interior FeaturesSAIC MG has equipped the MG4 with technology features that aim to exceed customer expectations at its price point:Qualcomm Snapdragon 8155 in-car chip provides the processing power for infotainment and smart cockpit operations.Lower trims have a 12.8-inch central infotainment screen .The Smart and semi-solid-state models feature an upgraded 15.6-inch 2.5K resolution display , enhancing media, navigation, and interface clarity.This focus on interior tech places the MG4 in line with other well-spec’d EVs in China that emphasize digital experience alongside powertrain improvements.Market Impact and SalesSAIC MG reported that it delivered over 13,000 new MG4 models in November , showing strong early demand. Beyond China, the company has touted the MG4 as a flagship for its independent Chinese brand ambitions overseas, particularly in the European Union and the United Kingdom , where it aims to expand its footprint against established EV players.The MG4’s competitive pricing, combined with advanced battery tech and ample range, could influence how consumers view affordability in the EV market and push traditional automakers toward adopting similar battery innovations.Safety and Battery InnovationThe semi-solid-state battery’s lower liquid electrolyte level is a standout safety feature. Traditional lithium-ion batteries with high liquid electrolyte content can pose risks under extreme conditions, including thermal runaway. By reducing liquid content to around 5 percent , SAIC MG says it improves battery safety without compromising energy storage, a critical balance for EV adoption.In controlled tests, the semi-solid-state battery’s resilience under puncture conditions suggests a breakthrough that could inform broader industry trends toward safer, higher-performance EV batteries.This delivery marks a notable milestone in EV development, blending affordability, range, safety, and technology in a package that could resonate across markets. The MG4 with semi-solid-state battery sets a new benchmark for what consumers and manufacturers might expect from next-generation electric vehicles.
