The electric vehicle landscape just witnessed a significant milestone with the unveiling of the second-generation MG4 EV at China’s Chengdu Auto Show 2025. This isn’t just another electric car refresh – it represents a technological leap forward that could reshape how we think about EV batteries and performance.
A Bold New Chapter for Electric Mobility
What makes this launch particularly exciting is MG’s decision to introduce the world’s first mass-production electric vehicle equipped with semi-solid-state battery technology. While this advanced battery option won’t arrive until September 2025, its implications for the entire EV industry are profound.
The pricing strategy remains refreshingly accessible, with the entry-level model starting at 68,800 yuan (approximately $8,500). For perspective, this positions the MG4 EV as one of the most affordable electric vehicles offering premium features and cutting-edge technology.
Engineering Excellence: What’s Actually New
The engineering team at SAIC has completely reimagined the MG4 EV using their sophisticated E3 pure electric architecture. The transformation is immediately visible – this electric hatchback has grown substantially while somehow becoming lighter than its predecessor.
Physical dimensions tell an interesting story. The new model stretches 4,395mm in length, representing a significant 108mm increase over the original. Width expands by 6mm to 1,842mm, while height increases by 35mm to 1,551mm. Perhaps most importantly for passenger comfort, the wheelbase extends by 45mm to 2,750mm, creating noticeably more interior space.
Despite these size increases, the vehicle’s curb weight drops dramatically from 1,635kg to just 1,485kg – a remarkable 150kg reduction. This weight optimization directly translates to improved efficiency, better handling characteristics, and enhanced overall performance.
Battery Innovation That Changes Everything
The semi-solid-state battery technology deserves special attention because it addresses several persistent challenges facing current electric vehicles. Traditional lithium-ion batteries, while effective, have limitations in extreme weather conditions, charging speeds, and long-term durability.
MG’s semi-solid-state solution promises enhanced thermal safety, making the vehicle safer in various climate conditions. Cold weather performance – historically a weakness for electric vehicles – sees significant improvement. The battery also offers extended lifespan and higher energy density, meaning more range from a smaller, lighter battery pack.
When available in the Anxin Edition, this 70kWh semi-solid-state battery will deliver an impressive 537km of CLTC-rated range. For drivers who don’t need the absolute latest battery technology, two conventional lithium iron phosphate options remain available: a 42.8kWh unit providing 437km range, and a 53.9kWh pack offering 530km range.
Fast charging capabilities remain impressive across all variants, with 30% to 80% charging accomplished in approximately 20 minutes using compatible DC fast chargers.
Performance Meets Efficiency
The powertrain centers around an integrated six-in-one electric motor system generating 120kW (161 horsepower) and 250Nm of torque. While these numbers might seem modest compared to high-performance electric vehicles, they’re perfectly calibrated for the MG4’s intended use as an efficient, practical daily driver.
The combination of reduced weight and optimized aerodynamics means this power output delivers engaging performance while prioritizing efficiency. The top speed of 160km/h provides adequate highway capability for most markets.
Technology Integration Done Right
Interior technology reflects modern expectations without overwhelming drivers with unnecessary complexity. The infotainment system features either a 12.8-inch touchscreen in base models or a larger 15.6-inch unit in higher trims, complemented by a 10.25-inch digital instrument cluster.
What’s particularly noteworthy is MG’s partnership with Oppo for software development, utilizing the powerful Qualcomm Snapdragon 8155 system-on-chip. This collaboration brings smartphone-like responsiveness and intuitive interface design to the automotive environment.
Advanced driver assistance systems showcase serious capability, especially in top-trim models. The sensor array includes four 360-degree cameras, twelve ultrasonic sensors, and dedicated front and rear cameras. These systems are powered by the Horizon Journey J6e processor, enabling sophisticated Navigation On Autopilot functionality.
Features like intelligent lane keeping, autonomous lane changing, turn signal-activated lane changes, and automated parking represent practical applications of semi-autonomous driving technology.
Global Market Positioning
The MG4 EV’s competitive positioning becomes clear when examining its international rivals. In European markets, it directly challenges established players like the Volkswagen ID.3, Cupra Born, and Renault Mégane E-Tech Electric.
However, MG’s pricing advantage could prove decisive. While European competitors often start above €30,000, the MG4 EV’s accessible pricing makes electric mobility available to a broader audience.
Design Philosophy: Sporty Yet Practical
Visual updates reflect contemporary electric vehicle design trends while maintaining the model’s distinctive character. The front fascia features new projector headlamps and a prominent split honeycomb grille that manages airflow efficiently. Sporty side air ducts and an illuminated MG logo add premium touches.
The side profile maintains clean lines with conventional door handles, body-colored mirrors, and attractive machined alloy wheels. The slightly tapering roofline creates a coupe-like silhouette without compromising rear passenger headroom.
Rear design elements include interconnected LED taillights, a functional roof spoiler, and a distinctive bumper design that emphasizes the vehicle’s wide stance.
What This Means for Electric Vehicle Adoption
The 2025 MG4 EV represents more than just another model year update. It demonstrates how rapidly electric vehicle technology is advancing and how accessible this technology is becoming for average consumers.
The introduction of semi-solid-state battery technology in a mass-market vehicle could accelerate broader industry adoption of these advanced energy storage systems. If MG can successfully implement this technology at scale, other manufacturers will likely follow suit rapidly.
For consumers, this translates to better electric vehicles becoming available at increasingly competitive prices. The combination of improved range, faster charging, enhanced safety, and advanced features in an affordable package could help overcome remaining barriers to electric vehicle adoption.
