MG is expanding its semi-solid-state battery technology beyond electric vehicles, announcing plans to introduce the advanced batteries in a new line of plug-in hybrid SUVs. The first model to feature this technology will be the MG ZS Plug-In Hybrid+, scheduled for release in 2027.
MG’s Semi-Solid-State Battery Expansion
Earlier this year, MG claimed it had become the first automaker globally to mass-produce semi-solid-state batteries. The technology debuted in the MG4, which went on sale in China last year as the industry’s first mass-produced EV with a semi-solid-state battery.
MG has announced that it will bring this battery technology to Europe by the end of 2026, starting with the all-electric MG4 Urban. The company also confirmed that its SolidCore semi-solid-state batteries will be used in at least three upcoming plug-in hybrid SUVs.
Upcoming Plug-In Hybrid Models
The first PHEV to feature MG’s semi-solid-state batteries will be the MG ZS Plug-In Hybrid+, set to launch in 2027. This model will be followed by two additional SUVs, the MG HS and MG S9.
MG’s new PHEV+ system will be available with either a 1.1L turbocharged or 1.5L turbocharged hybrid engine. The semi-solid-state batteries are designed to work in tandem with this system to improve range, performance, and charging speeds, even in extreme temperatures.
Technical Highlights and Efficiency Claims
According to MG, its semi-solid-state batteries deliver higher energy conversion efficiency and faster power response compared to conventional liquid-electrolyte batteries. The new hybrid transmission features an EV Mode that is designed to maximize both fuel and electrical energy efficiency.
MG stated that the intelligent drive system enables the engine to maintain thermal efficiency above 40% across approximately 90% of driving conditions, while achieving up to 90% electric drive efficiency. The company described the new hybrid transmission as achieving “a new benchmark in overall energy utilization.”
Advanced Driver Assistance Features
MG also revealed plans to introduce Navigate On Autopilot in late 2027 as part of its updated MG Pilot ADAS system. This feature is intended to support highway driving and enhance the overall driver assistance capabilities of upcoming models.
Why this matters
MG’s move to integrate semi-solid-state batteries into plug-in hybrids marks a significant step in battery technology adoption beyond pure EVs. If MG’s claims hold true, these advancements could lead to improved efficiency, performance, and usability for hybrid vehicles, especially in challenging climates.
The introduction of advanced driver assistance features like Navigate On Autopilot further signals MG’s commitment to integrating new technologies across its future lineup.
What this means for buyers
Buyers considering a plug-in hybrid SUV may soon have access to models with next-generation battery technology, potentially offering better range and performance than current options. Those interested in advanced driver assistance features should watch for the late 2027 rollout of MG’s Navigate On Autopilot system.
Prospective buyers in Europe and other markets should monitor MG’s announcements for regional availability and further details on pricing and specifications as the 2027 launch approaches.
