- Mercedes-Benz has launched large-scale production of its new axial flux motor at its Berlin-Marienfelde facility in Germany.
Mercedes-Benz has officially commenced large-scale production of its newly developed axial flux motor at its Berlin-Marienfelde manufacturing facility in Germany. The compact and high-output electric motor is entering series production for the first time and will make its debut in the Mercedes-AMG GT 4-Door Coupe. This milestone represents a significant advancement in electric powertrain manufacturing and reflects the company's efforts to industrialize next-generation motor technologies while maintaining high levels of production efficiency and quality.
The production system for the axial flux motor consists of 98 individual manufacturing steps, many of which are being implemented for the first time within Mercedes-Benz operations. These newly introduced processes have resulted in more than 30 patent applications, highlighting the innovative nature of the production technology. The manufacturing footprint covers approximately 30,000 square metres across three production halls and seven dedicated production lines, integrating advanced automation, laser-based technologies, intelligent control systems, AI-supported quality inspection processes, and highly skilled personnel.
The axial flux motor's compact architecture and high-performance characteristics require exceptionally precise manufacturing standards, dependable process control, and sophisticated automation technologies. To meet these requirements, Mercedes-Benz developed and adapted several specialized production techniques specifically for this motor before successfully scaling them for volume manufacturing. The company emphasized that achieving consistent quality and precision was a critical factor in preparing the motor for large-scale deployment.

The technology foundation for the motor originates from YASA, a company based in the United Kingdom, which developed an advanced version of the axial flux motor architecture. Mercedes-Benz further refined this technology for integration into its high-performance electric vehicle platform. The resulting design combines compact dimensions with strong power density, making it suitable for performance-focused electric mobility applications.
Within the Mercedes-AMG GT 4-Door Coupe, the front-mounted axial flux motor measures less than 9 centimetres in width, while each of the two rear-mounted motors is approximately 8 centimetres wide. These compact motors are integrated with transmission systems to create High Performance Electric Drive Units (HP.EDU). This packaging approach enables a highly efficient and space-saving drivetrain configuration while supporting the vehicle's performance objectives through advanced electric propulsion technology.
