The future is semi-solid: MG 4X promises record performance and increased safety

MG continues to shake up the electric vehicle market, and this time it’s all about cutting-edge technology. The British-Chinese manufacturer has officially lifted the curtain on the MG 4X, a compact crossover that not only expands the popular MG4 family, but also marks a historic moment for the brand: the introduction of semi-solid-state batteries on a production model.

Although MG already has a solid portfolio, the new 4X comes to fill the gap between the agile hatchback and the more voluminous SUVs, being strategically positioned below the MG S5 model.

Technology Under the Hood: The Game-Changing Battery

The biggest change to the MG 4X is under the floor. The new model is equipped with a 53.95 kWh battery based on a semi-solid state lithium-ion manganese chemistry.

What does this mean for the user?

• Increased safety: With a liquid electrolyte content reduced to just 5%, the risk of fire in the event of an impact is drastically reduced.
• Cold performance: MG promises almost 14% better range retention in freezing conditions compared to classic LFP batteries.
• Autonomy and Charging: The model promises a range of approximately 510 - 530 km (according to the CLTC cycle). More impressive is the charging time: thanks to 2C technology, the battery can be charged from 30% to 80% in just 21 minutes.

In terms of performance, the MG 4X is powered by a 120 kW (approximately 163 hp) electric motor, reaching a top speed of 160 km/h.

Design: Minimalist, but with "X" personality

The MG 4X adopts a more fluid and “soft” design language compared to the sharp angles of the MG4. At 4.4 meters long, 1.84 meters wide and 1.55 meters high, the car retains a generous 2.75-meter wheelbase, promising surprising interior space for its exterior dimensions.

Key visual elements:

• Front: A fully enclosed grille flanked by LED headlights joined by a thin light strip and an illuminated logo – a rare premium detail in this segment.
• The profile: An aggressively sculpted waistline and petal-shaped rims that emphasize the dynamic character.
• Rear: LED taillights in the shape of the letter "T" (or "arrow", inspired by the Cyberster) and a discreet segmented spoiler.

A "Smart Cockpit" developed with Oppo

Although full interior images are still under embargo, MG has confirmed a high-profile collaboration with tech giant Oppo. The result? The "Hand-Car Interconnection" system.

This interface promises a seamless fusion between smartphone and car. Users will be able to transfer apps from their phone directly to the car's central screen, benefit from gesture navigation and a voice assistant capable of putting the vehicle into "standby" with complex commands. All powered by the Qualcomm Snapdragon 8155 processor, ensuring a lag-free experience.

When will we see it on the roads?

The commercial launch of the new MG 4X is scheduled for the second half of 2026. Given MG's recent strategy of aggressively reducing prices to compete with rivals such as BYD or Tesla, the 4X is expected to be one of the most affordable high-tech crossovers on the market.

Our take: The MG 4X isn't just another electric car; it's a laboratory on wheels that brings semi-solid-state battery technology (previously reserved for luxury models) to the affordable segment. If its winter performance holds up, it could quickly become a favorite in temperate European markets.
