Uncovering Information
The British automaker MG is gearing up for the full market launch of its new compact electric vehicle, the MG4, in early September. The new model represents a comprehensive overhaul of the current MG4, positioning it to compete directly with recent entries in the compact EV segment.
One of the standout features of the MG4 is its rear-mounted motor, which boasts a power output of 120 kW (163 hp). The vehicle is also equipped with a 70 kWh battery pack, featuring a semi-solid-state electrolyte supplied by QingTao Energy. This innovative battery technology, which uses a hybrid electrolyte consisting predominantly of a semi-solid or gel-like electrolyte, aims to combine the safety and thermal stability benefits of solid-state batteries with the easier manufacturing and ion mobility characteristics of traditional liquid batteries.
The MG4's battery has undergone rigorous safety tests, including a 360-degree puncture test, enhancing its safety profile. It offers a CLTC-rated driving range of approximately 537 km (334 miles), with an energy density of around 180 Wh/kg—similar to that of standard lithium-ion batteries currently used in many electric vehicles.
The semi-solid-state approach provides improved safety, better performance in cold weather, and structural robustness. The reduced liquid electrolyte lowers the risk of leakage and fires, while the battery shows about 13-14% improved range retention at -7°C compared to traditional lithium iron phosphate (LFP) batteries. The battery's greater mechanical integrity is evident in its ability to pass severe puncture tests.
However, it's important to note that the MG4's battery is considered "semi-solid-state" because it uses less than 10% liquid electrolyte, indicating that the technology is still evolving and not yet delivering some of the more ambitious performance gains expected from fully solid-state batteries.
The new MG4 is larger than both the previous MG4 and the BYD Dolphin, measuring 4,395 mm in length, 1,842 mm in width, and 1,551 mm in height. It rides on 17-inch petal-style alloy wheels and offers two versions with CLTC ranges of 437 km and 537 km.
The new MG4 includes significant upgrades to its exterior design, interior technology, and powertrain. It features a rear-wheel-drive configuration and, according to reports, may include an L2+ system for advanced driver assistance capabilities. The all-new MG4 has already been spotted at dealerships in China, with the official pre-sale beginning on August 5.
Fast charging from 30% to 80% in the MG4 takes approximately 20 minutes. The vehicle does not have MacPherson suspension in the front but instead uses a front torsion beam suspension. The new MG4 is a rear-wheel-drive vehicle, and its driver assistance capabilities may include an L2+ system.
The MG4 is an updated compact electric hatchback, set to make its mark in the competitive EV market with its innovative semi-solid-state battery technology and comprehensive upgrades. With its launch just around the corner, electric vehicle enthusiasts are eagerly awaiting the opportunity to experience this new offering from MG.
- The MG4, with its rear-mounted motor and semi-solid-state battery technology supplied by QingTao Energy, is positioned to challenge competitors in the compact electric vehicle (EV) sector.
- The semi-solid-state battery in the MG4 offers improved safety, better performance in cold weather, and structural robustness, thanks to reduced liquid electrolyte and higher energy density, similar to that of standard lithium-ion batteries.
- The MG4 provides fast charging from 30% to 80% in about 20 minutes, rides on 17-inch alloy wheels, and comes in two versions with CLTC ranges of 437 km and 537 km.
- As the MG4 approaches its market launch in early September, anticipation builds among electric vehicle enthusiasts, eager to explore its cutting-edge features and tech-laden lifestyle inspired by the automotive and technology industries.
