GAC Group Advances Amorphous-Alloy Electric Drives

On September 23, GAC Group announced that it jointly held the Forum on the Integration of Scientific and Industrial Innovation in Amorphous-Alloy Electric Drives and the Cooperative Achievement Release Event with the Dongguan Institute of Materials Science and Technology (DIMST), Chinese Academy of Sciences. The event highlighted how GAC Group amorphous-alloy drives are moving from advanced materials research toward practical vehicle applications. The development centers on integrating amorphous-alloy materials into electric drive systems for passenger vehicles, with the companies presenting mass-produced models that demonstrate the technology's transition from scientific research into automotive manufacturing.

Amorphous-Alloy Electric Drives Enter Mass-Production Vehicles

Three mass-produced passenger vehicles were showcased at the event: the 2027 Aion RT, Aion N60, and Aion i60. Each model is equipped with an amorphous-alloy electric drive system, providing a direct demonstration of the technology in vehicles intended for series production. Their joint presentation represents a step in applying advanced amorphous-alloy materials beyond laboratory and development environments. The move also connects materials science with vehicle-level electric propulsion, as the technology is being incorporated into passenger-car electric drive systems rather than remaining limited to basic research or experimental applications.

Electric Drive System Delivers High Efficiency

The motor used in the amorphous-alloy electric drive system achieves a peak efficiency of 99.03%, a maximum speed of 30,000 rpm, and a power density of 17.29 kW/kg. At the complete electric-drive-system level, operating-cycle efficiency reaches 94.18%. These figures describe the system's performance characteristics across efficiency, rotational speed, and power density. The technology has also received certification from authoritative organizations in China and abroad, including the China Automotive Technology and Research Center Co., Ltd. (CATARC) and TÜV Rheinland AG (TÜV Rheinland), adding formal validation from recognized automotive and testing organizations.

GAC Group and DIMST Plan Further Development

Following the event, DIMST and GAC Group are expected to deepen their cooperation on a new generation of high-performance amorphous materials. The stated objective is to support broader adoption of advanced battery, electric motor, and power electronics technologies across mainstream and more affordable vehicle models. This approach extends the collaboration beyond the specific drive systems already demonstrated, focusing on materials and electric propulsion technologies that can potentially be applied across a wider portion of the passenger-vehicle portfolio.

Certification Supports Automotive Application

The involvement of China Automotive Technology and Research Center Co Ltd and TÜV Rheinland AG is part of the technology's documented validation in China and internationally. The certifications cited by GAC Group relate to a system that has already progressed into mass-produced vehicle applications. Combined with the performance figures disclosed for the motor and electric drive system, the certification activity provides supporting evidence for the transition from material development to automotive deployment. The three Aion models therefore serve as concrete examples of how the technology is being incorporated into passenger vehicles.

Industry Impact & Outlook

The development connects advanced materials research with the practical requirements of passenger-vehicle electrification, particularly electric motors, power electronics, and broader electric-drive integration. For GAC Group, continued cooperation with DIMST could support further development of high-performance amorphous materials and their application across mainstream vehicle programs. The immediate relevance is strongest in passenger vehicles using electric propulsion, while the next stated step is broader adoption across more affordable models. The disclosed efficiency, speed, and power-density figures also provide measurable technical benchmarks for the company's ongoing development of electric-drive technologies.
