MG Teases New 4X Electric SUV With Semi-Solid-State Battery, 500km Range

MG has previewed a new compact electric SUV in China called the MG 4X, and it could become one of the brand’s most important EV launches yet for markets like Australia.

The new SUV has been teased through images shared on parent company SAIC Motor’s official Weibo account, revealing a fresh electric model that blends familiar MG styling with a new-generation battery technology the company describes as a “liquid-solid state battery”.

While full technical details are still emerging, the MG 4X appears positioned as a family-focused electric SUV sitting somewhere between the MG4 hatchback and the MG S5 SUV already sold locally. Early indications also point to aggressive pricing, long driving range and upgraded battery chemistry designed to improve efficiency and safety.

For Australian buyers, it could eventually become one of the cheapest long-range electric SUVs on the market if local pricing lands below the projected $35,000 mark.

What is the MG 4X and where does it fit in MG’s EV lineup?

The MG 4X is a new small electric SUV expected to launch first in China in the coming months before expanding to export markets during 2026.

At around 4.5 metres long, the SUV slots into the rapidly growing compact EV segment (BYD Atto 2, Jaecoo J5 EV, GWM Ora 5 EV) and adopts much of the same design language seen on the MG4 Urban hatchback and MG S5 electric SUV.

The exterior features sharp LED lighting, sculpted bodywork and a more rounded aerodynamic profile than earlier MG EVs. The overall styling is clearly aimed at mainstream family buyers rather than performance-focused customers.

Inside, MG has moved further toward a minimalist cabin design. Images show a large central infotainment screen paired with a smaller 10.25-inch digital driver display positioned behind the steering wheel.

Unlike some earlier MG interiors that relied heavily on touch controls, the 4X still retains physical shortcut buttons underneath the display for climate and key vehicle functions.

The company’s translated teaser message also hints at the SUV’s broader positioning:

“Comfortable driving experience | Fully equipped cabin | Smart ecosystem. Sets a new benchmark for comfortable family travel.”

That language strongly suggests MG is targeting practicality and comfort rather than simply headline performance figures.

Why is the new “liquid-solid state battery” important?

The biggest talking point surrounding the MG 4X is its new battery technology.

MG says the SUV will debut a “liquid-solid state battery” featuring:

• 95 per cent solid electrolyte
• 5 per cent liquid electrolyte
• Improved energy density
• Faster and more stable power delivery
• Enhanced thermal safety

While this is not a fully solid-state battery in the traditional sense, it represents another step toward next-generation battery systems that promise higher efficiency and improved safety compared with conventional lithium-ion packs.

The entry-level battery is expected to offer:

• 54kWh capacity
• Up to 510km CLTC driving range
• Estimated 400km WLTP range

A larger CATL-supplied battery pack is also expected, increasing capacity to 64kWh and adding roughly another 100km of range under Chinese testing standards.

The introduction of semi-solid-state battery technology in a relatively affordable EV is particularly significant because these systems have previously been limited mostly to expensive concept vehicles and premium EV programs.

How much power does the MG 4X offer?

The MG 4X is expected to launch with two rear-wheel-drive motor options.

The standard version uses a rear-mounted electric motor producing up to 125kW, while higher-spec variants increase output to 150kW.

MG has not released official acceleration figures yet, but reports from China suggest the SUV could complete the 0-100km/h sprint in around eight seconds.

That makes it slightly slower than the MG4 hatchback currently sold in Australia, though the focus here appears to be range, comfort and practicality rather than outright performance.

What could the MG 4X mean for Australia?

If MG brings the 4X to Australia at an aggressive price point, it could become a major disruptor in the local EV market.

The combination of:

• Compact SUV practicality
• Around 400km real-world range
• Semi-solid-state battery technology
• Familiar MG styling
• Potential sub-$35,000 pricing

would place it directly against some of Australia’s most affordable EVs while offering newer battery technology than many established rivals.

That matters because Australia’s EV market is increasingly shifting toward value-focused family SUVs rather than premium performance cars.

MG already has strong momentum locally thanks to the MG4 hatch and growing electric lineup. A competitively priced 4X could help the company further expand its market share as buyers look for practical EVs with longer range and lower running costs.

The timing is also notable. Chinese car makers are now moving beyond simply offering cheaper EVs and are starting to introduce newer battery chemistries and software-focused technologies ahead of many traditional manufacturers.

For Australian buyers, the MG 4X could end up being one of the first relatively affordable EVs to bring semi-solid-state battery technology into the mainstream market.
