MG's Semi-Solid-State Battery Leap: What It Means for Australian MG Owners
CarMoods TeamMG used its Tech Day in London on 8 July to lay out one of the boldest battery roadmaps we've seen from a mainstream brand. From 2027, MG's plug-in hybrids will switch to semi-solid-state batteries — a technology the company calls SolidCore — starting with the next-generation ZS, followed by the HS and the S9.
The MG4 hatch gets the new chemistry first, and the claimed benefits are the kind owners actually feel: more range, faster charging, stronger cold-weather performance and more consistent output whether you're crawling through traffic or climbing a hill.
It's a big statement from a brand Australians already buy in serious numbers. And if there's an MG3, MG4, ZS or HS in your driveway right now, you don't need to wait until 2027 to make it feel special. A few smart interior accessories from our MG collection — starting with something as simple as a proper steering wheel cover — can transform the daily drive today.

What MG actually announced
Semi-solid-state batteries sit between today's liquid-electrolyte lithium packs and the full solid-state cells the whole industry is chasing. By replacing most of the liquid electrolyte with a gel-like material, the pack becomes more stable across a wider range of temperatures and driving conditions.
According to MG's lead scientist Li Zheng, that stability is the headline act. In a plug-in hybrid it even allows the petrol engine to be downsized, because the battery can shoulder more of the work more of the time.
MG has been clear this isn't a concept-car promise. SolidCore is set to become the brand's predominant battery technology while full solid-state development continues in the background.
Why it matters for Australian MG owners
Australia has become one of MG's strongest markets, and battery tech that copes better with temperature swings is genuinely useful here — think frosty Canberra mornings and 40-degree summer school runs in the same ownership year.
The other takeaway is resale confidence. A brand investing this heavily in next-generation batteries is a brand planning to stick around, which is good news for anyone who already owns one. It also means your current MG will be on Aussie roads for years yet — all the more reason to keep its cabin comfortable, protected and looking sharp.
Pro tip
Brand-specific accessories are cut for your car's exact dimensions — an MG-fit steering wheel cover or floor mat set will always sit better than a generic one-size-fits-most alternative.
Comfort upgrades you can fit this weekend
Long before the 2027 models arrive, the cheapest upgrade to any MG is better support for the person driving it. A contoured headrest pillow takes the strain off your neck on the commute, while lumbar support keeps your lower back happy on longer runs up the coast.

If MG's battery roadmap tells us anything, it's that these cars are built for a long ownership life. Custom-fit mats are the difference between a five-year-old interior that looks tired and one that looks barely run in.
MG4 owners are especially well served — TPE all-weather mats shrug off beach sand, muddy boots and spilt coffee, and hose clean in minutes.

One underrated part of the MG electric story is vehicle-to-load capability — using your car's battery to run appliances. If your MG supports V2L, a discharger adapter turns the traction battery into a camp-site power point for a kettle, laptop or portable fridge.
As batteries get denser with SolidCore, this trick only gets more useful. It pairs beautifully with our travel and road trip essentials.

The bottom line
MG's SolidCore announcement is a glimpse of where the brand is heading: longer range, faster charging and batteries that don't flinch at Australian weather. The 2027 models will be worth the wait.
