Hybrid+ and Semi-Solid Battery Tech to Shape MG’s Next-Gen Vehicle Lineup
MG is developing a new generation of hybrid powertrains that focus on improved efficiency, refinement, and performance.
The system, branded as Hybrid+, is being engineered at MG’s technical centre in Frankfurt, Germany and is expected to appear first in an upcoming plug-in hybrid SUV, reportedly the MG S9.
A key element of this system is the introduction of an electrically assisted turbocharger capable of operating at speeds of up to 70,000 rpm. This unit is designed to improve throttle response and overall efficiency while smoothing the transition between electric and internal combustion power.
The Hybrid+ setup also integrates a digital damping control system. Instead of relying solely on mechanical isolation, the vehicle uses sensors to detect engine and drivetrain vibrations in real time.
The electric motor then actively counteracts these vibrations, reducing noise and improving cabin comfort. This approach also reduces energy losses associated with vibration and heat, contributing to better overall efficiency.
In parallel, MG is working on upgrades to its electric vehicle lineup. A semi-solid-state battery is planned for a higher-spec version of the MG4 electric hatchback later this year. If introduced as planned, it would represent one of the first mass-market applications of this battery chemistry.
To support the Hybrid+ system, MG is also increasing battery capacity to around 1.83 kWh in its hybrid models. Combined with the electric turbo and vibration control system, the updated architecture is aimed at delivering smoother power delivery, lower noise levels, and improved responsiveness compared to previous hybrid systems.
