MG Reveals Future Technology Roadmap with Plug-in Hybrid+, SolidCore Battery and Advanced Driver Assistance

MG has unveiled a comprehensive technology roadmap at its UK headquarters, introducing a new Plug-in Hybrid+ powertrain and semi-solid-state SolidCore battery technology. This strategic shift aims to bridge the gap between internal combustion and full electrification by offering high-efficiency hybrid systems with thermal efficiencies exceeding 43%. For the electric vehicle sector, these advancements represent a significant move toward more stable, high-performance battery architectures and localized driver assistance systems tailored for complex European road environments.

MG’s new Plug-in Hybrid+ system centers on dedicated 1.1-liter and 1.5-liter turbocharged engines designed to achieve thermal efficiencies of 42% and 43%, respectively. The powertrain utilizes Power Split and Motor Decoupling technologies to optimize the balance between engine and electric motor output, prioritizing electric power at low speeds and direct engine drive for motorways. This configuration reportedly maintains thermal efficiency above 40% during 90% of normal driving conditions while reducing cabin noise by 5 dB compared to conventional hybrids. Performance is also enhanced, with 0-62 mph acceleration in under six seconds and a 72% increase in hill-start capability. The first production vehicle to utilize this technology will be the MG ZS Plug-in Hybrid+, slated for a 2027 release.

A cornerstone of the roadmap is the introduction of SolidCore Battery technology, a semi-solid-state architecture featuring a 3D spinel structure. Unlike conventional liquid-electrolyte batteries, this design offers higher energy conversion efficiency and faster power delivery while mitigating performance degradation as the state of charge drops. MG plans to integrate these batteries into three upcoming SUVs across the B-, C-, and D-segments. By focusing on semi-solid-state solutions, the company aims to enhance the stability and reliability of its electrified lineup, positioning these models as high-performance alternatives to traditional plug-in hybrids that often suffer from power loss as batteries deplete.

On the software front, MG is leveraging 1.2 million kilometers of European driving data to refine its advanced driver assistance systems (ADAS). The roadmap includes the One Touch iAD intelligent parking system, which supports 30 parking scenarios and recognizes over 300 space types, including those without painted lines. MG’s next major milestone is the Navigate On Autopilot (NOA) feature, with a highway version scheduled for a late 2027 debut on a new SUV and a city-focused version handling intersections and pedestrians expected in 2028. Additionally, MG confirmed ongoing Level 4 Robotaxi testing in Germany, China, and the Middle East, signaling long-term ambitions for fully autonomous commercial deployment beyond the current consumer roadmap.
