MG4 2026 Semi-Solid Battery Edition Vehicle Profile: Best 530km Range Compact EV with World's First Mass-Produced Semi-Solid Battery
Model Overview
The MG4 is SAIC Motor's MG-brand compact pure-electric hatchback aimed at the global market, and a flagship ground-up EV built on SAIC's dedicated electric architecture. The 2026 facelift arrived in the Chinese market in August 2025, and the Semi-Solid Battery Edition steals the spotlight — SAIC brought semi-solid battery technology, previously reserved for 200,000-RMB-class models, down to the 100,000-RMB segment, making it the world's first mass-produced vehicle equipped with a semi-solid battery.
As a ground-up model from a traditional automaker, the MG4 does not follow an "oil-to-electric conversion" route; the body structure and cabin layout were redesigned around a pure-electric platform. The semi-solid battery combined with CTB battery-chassis integration not only improves safety but also frees vertical rear cabin space, allowing even a 1.8m-tall passenger to ride comfortably. Its market positioning targets the 100,000-RMB-class compact EV market, directly against the AION S, BYD Dolphin, and MG 4X, with its differentiators being "battery upgrade + safety upgrade + charging-efficiency upgrade."
In design, the MG4 adopts MG's sporty family design language. The compact hatchback body is agile, with body-color accents for a youthful, urban style. Measuring 4395×1842×1551mm with a 2750mm wheelbase, it balances agile handling with practical space. As a global model, the MG4 also enjoys solid market performance overseas, especially in Europe — one of the few Chinese-made EVs that sells well both home and abroad.

Three Highlights & Three Caveats
Highlight 1: 530km Range + World's First Mass-Produced Semi-Solid Battery The MG4 Semi-Solid Battery Edition is powered by a Qingtao (QingTao) 53.9kWh semi-solid battery with a CLTC range of 530km. Compared with conventional liquid lithium batteries, semi-solid electrolytes offer better thermal stability under nail penetration, overcharge, and high-temperature conditions, barely smoking or catching fire. Safety clearly leads its class — a rare "battery upgrade" in the 100,000-RMB segment.
Highlight 2: ~21-Minute Fast Charge, Fastest Replenishment in Its Class Charging from 30-80% takes about 21 minutes, with 2C fast-charge support — the only model in its class with 2C fast charge across the range. In real tests on a 120kW charger, it replenishes roughly 260km of range in 20 minutes — enough for over 200km more while you grab a coffee.
Highlight 3: Structural Upgrade, CTB Integration & Excellent Efficiency The semi-solid battery pairs with CTB battery-chassis integration, raising torsional rigidity by 30% while freeing up vertical cabin space. Energy consumption is only 11.9kWh/100km, so a single full charge covers a week of commuting at very low running cost.
Caveat 1: Relatively Thin Brand Presence in EVs As the locally-built MG brand under SAIC, its voice in the pure-electric market still trails heads like BYD and GAC Aion, so market awareness and used-car value remain to be seen.
Caveat 2: Average Infotainment Ecosystem While the SAIC OS infotainment running on the 8155 chip feels smooth, the app ecosystem and voice interaction are less rich than those of leading new-energy brands.
Caveat 3: Non-Independent Rear Suspension The rear uses a torsion-beam non-independent suspension, prioritizing ride comfort and cost for urban commuting. Under extreme driving or on continuous bumpy roads, rear-seat filtering quality lags multi-link rear-suspension rivals.
Ownership Costs & Service
Warranty Policy The vehicle carries a 3-year/100,000km warranty, and first owners enjoy a lifetime three-electric warranty (liability exemptions subject to official terms), providing reassuring long-term coverage.
Maintenance Cost As a compact hatchback EV, the MG4's maintenance items are simple, mainly covering three-electric-system checks, cabin filter replacement, and routine inspections. The pure-electric structure plus the lifetime three-electric warranty keeps long-term maintenance very affordable.
Charging Cost (estimated at the Global Petrol Prices world-average residential electricity price)
Using a global average residential electricity price of about 0.17 USD/kWh, fully charging the MG4's 53.9kWh battery costs about 9.2 USD. At a 530km CLTC range, that works out to roughly 1.7 USD per 100km — far less than the per-100km fuel cost of a comparable gasoline car.
Real Ownership Cost Analysis The biggest savings of an EV come from energy and maintenance. At an annual 20,000km, the MG4's yearly electricity cost is about 340 USD and maintenance about 100-200 USD, versus several thousand USD per year in fuel and upkeep for a comparable gasoline car — making long-term ownership highly cost-effective. The lifetime three-electric warranty further lowers ownership risk.

Competitors Comparison
In the 100,000-RMB pure-electric market, the MG4 Semi-Solid Battery Edition faces three rivals from Aion, BYD, and its own stable. Below we break down the strengths and weaknesses of each across four dimensions: range, power, charging, and features.
-
Range: MG4's 530km leads the pack: Compared with the AION S's 430km, the BYD Dolphin's 420km, and the MG 4X's 510km, the MG4 offers the longest CLTC range and a higher safety ceiling thanks to its semi-solid battery.
-
Power is upper-mid, torque ample: The MG4's 163hp and 250N·m torque beat the AION S (136hp) and Dolphin (95hp), offering a stronger power reserve; the MG 4X edges ahead with 170hp and rear-wheel drive.
-
Charging efficiency fastest in class: The MG4 fast-charges in about 21 minutes (30%-80%) with 2C support, better than the Dolphin's and MG 4X's 25 minutes and the AION S's conventional performance — a core strength.
-
Battery technology clearly differentiated: The MG4's semi-solid battery offers a higher safety ceiling, while the Dolphin uses blade batteries and the AION S uses clip (ammunition-box) batteries — each route differs, but the MG4's "premium upgrade" is more striking.

Real Owner Reviews
Positive Feedback
Range & Efficiency Owners widely acknowledge its honest range and low consumption, with real-world range close to the rated figure.
"The range is quite honest — over 450km in the city is no problem, and consumption is just over 11kWh/100km. One charge a week is enough for commuting."
Charging Speed The 2C fast-charge efficiency earns widespread praise, and owners find it very convenient.
"Fast charging is genuinely quick — from 30% to 80% in about 20-odd minutes, enough time for a coffee. No anxiety even on long trips."
Driving & Space The compact hatchback is agile to drive, and the CTB-integrated cabin space performs well.
"The car isn't big but it's very agile to drive, and the rear space is decent — I'm 1.8m tall and I can sit up without touching the roof. Very comfortable for family commuting."
Negative Feedback
Low Brand Recognition & Infotainment Some owners are less satisfied with the brand's EV recognition and the richness of the infotainment ecosystem.
"It's a great car, but the MG brand isn't that well known in EVs yet, and the infotainment isn't as flashy as some new-energy brands. I hope they keep updating it."
Average Rear-Suspension Comfort The non-independent rear suspension performs only average on continuous bumpy roads — a point some owners mention.
"No problem in the city, but on stretches with continuous speed bumps or rough roads, the rear can feel a bit bouncy — the suspension leans firm."
