MG is set to significantly advance plug-in hybrid technology, announcing that its next-generation ZS Plug-in Hybrid+ will launch in 2027 equipped with pioneering semi-solid-state batteries. This strategic move, detailed at MG's recent UK Tech Day, marks a crucial expansion of its "SolidCore" battery technology beyond electric vehicles, with plans to integrate it into at least three new PHEV SUVs across B-, C-, and D-segments, including the HS and S9 models. Production for the ZS Plug-in Hybrid+ is slated for Q1 2027.
The integration of SolidCore semi-solid-state batteries, which MG claims to be the first mass-produced technology of its kind, promises substantial enhancements over conventional liquid-electrolyte batteries. These batteries feature an advanced 3D spinel structure, delivering higher energy conversion efficiency, faster power response, and improved stability across diverse driving and climatic conditions, including superior cold-weather performance without preheating. The reduced liquid electrolyte content also translates to enhanced safety by lowering thermal runaway risks.
This technological leap is paired with MG's new Plug-in Hybrid+ powertrain, featuring specially designed 1.1-litre or 1.5-litre turbocharged engines boasting thermal efficiencies exceeding 42%. A new hybrid transmission, incorporating "Power Split" and "Motor Decoupling" technologies, optimizes power delivery and reduces noise by up to 5dB in electric mode, aiming for an EV-like driving experience. This holistic approach positions MG to offer PHEVs with improved range, performance (0-62 mph in under six seconds), and efficiency, potentially setting a new benchmark for the segment. While semi-solid-state batteries are a pragmatic bridge to the ultimate goal of full solid-state, their deployment in mass-market PHEVs like the ZS underscores MG's aggressive push to democratize advanced automotive technology, challenging competitors to accelerate their own battery development timelines.
