MG announced the new generation of its electric hatchback, the MG4, equipped with semi-solid batteries that represent a qualitative leap in electric battery technology. Expected to launch in the Chinese market on August 4, 2025, the MG4 marks a bold step toward making electric vehicles available at competitive prices, supported by advanced technical performance that meets the expectations of consumers seeking reliability and efficiency.
Semi-solid battery technology: A clear future at affordable prices
The semi-solid batteries integrated into the MG4 are a significant improvement over traditional lithium-ion batteries. These batteries contain only about 5% liquid electrolyte, making them resemble a semi-solid gel rather than a fully liquid electrolyte found in conventional batteries. Developed by QingTao Energy, they strike a balance between high performance and safety, with notable advantages such as:
Better resistance to cold weather effects, maintaining full performance at temperatures as low as 19 degrees Fahrenheit (-7 degrees Celsius).
Reduced fire risk compared to liquid batteries.
Lightweight and compact design that reduces battery size without sacrificing range or power.
Although the energy density is slightly lower than the best modern liquid batteries, this technology enables MG to significantly reduce the vehicle’s cost, making the MG4 one of the cheapest electric vehicles available today, with prices starting from approximately $11,000 in the Chinese market.
Design and performance: The perfect blend of dynamics and practicality
The MG4 features a modern, sporty hatchback design with bold lines that emphasize its lively electric character. It measures about 4.29 meters in length with a 2.7-meter wheelbase, providing a spacious passenger cabin in a compact design suited for urban driving.
The car is powered by a strong front electric motor producing about 170 horsepower (125 kW) and 250 Newton-meters of torque, enabling acceleration from 0 to 100 km/h in approximately 7.9 seconds. These figures place the MG4 in the category of well-performing mid-range electric vehicles, especially with multiple driving modes ranging from economy to sport.
Technology and safety systems: A smart and secure cabin
The MG4 comes equipped with a comprehensive set of smart driver assistance systems, including:
Adaptive Cruise Control.
Intelligent emergency braking with pedestrian and cyclist detection.
Lane keeping assistance with departure warning.
Blind spot warning and lane change alert.
360-degree surround-view camera for parking assistance.
The interior includes a 10.25-inch touchscreen infotainment system supporting Apple CarPlay and Android Auto, alongside a digital climate control system that ensures comfortable trips in all conditions.
Battery range and charging: Multiple options for different needs
MG4 offers various battery pack options, with the announced model equipped with a semi-solid battery ranging from approximately 51 to 64 kWh, delivering a theoretical driving range between 255 and 350 kilometers depending on conditions and driving style. The vehicle supports fast charging capable of replenishing the battery up to 80% within a competitive short time, enhancing usability for daily use and medium-distance travel without concern.
Expected impact on the electric vehicle market
Through the MG4, MG introduces a reliable and affordable electric car that embodies the future of practical electric mobility, especially for developing markets and China. The semi-solid battery technology may serve as a bridge between traditional solid and liquid batteries, offering a balanced solution with greater safety, decent performance, and an affordable price.
If MG successfully scales this technology while maintaining quality and durability, it could encourage other manufacturers to adopt similar solutions, accelerating the global transition toward competitively priced electric vehicles with high performance.
The MG4 electric car with semi-solid batteries represents a crucial turning point in electric vehicle manufacturing. It is not only an affordable electric car but also an innovative technology that balances quality, cost, and safety. Amid significant challenges facing future mobility, the MG4 offers a promising model for a sustainable electric future.
