- Mercedes and Yasa Collaboration Paving the Way for a New Generation of AMG
The world of electric mobility is undergoing a major transformation, and Mercedes is once again leading the charge. Through its British subsidiary YASA, the brand has unveiled a groundbreaking electric motor that redefines what performance can mean in the EV era. This innovation is not just a step forward in engineering but a complete leap that could reshape the future of high performance electric cars. It combines extreme power with ultra lightweight construction, creating a balance never before achieved in automotive history.
Record Breaking Power to Weight Ratio
YASA has accomplished an extraordinary engineering milestone by boosting energy density to 59 kilowatts per kilogram, equivalent to 79 horsepower for every single kilogram. This achievement surpasses the company’s previous record of 42 kilowatts per kilogram and sets a new benchmark for electric performance.
Despite its incredibly compact design, the motor weighs only 12.7 kilograms and delivers staggering output figures:
Peak power: 1006 horsepower
Continuous power: between 469 and 604 horsepower
This combination of immense power and minimal weight makes the motor a perfect fit for high performance electric sports cars that demand rapid acceleration and top tier efficiency. Instead of relying on heavier batteries or larger chassis to boost output, Mercedes and YASA have engineered a technological solution from within, the motor itself. It delivers both scalability for production and an unprecedented level of power density that could redefine what electric performance means.
Axial Design Redefines the Industry
The new YASA motor relies on axial flux technology, a concept that differs completely from the traditional radial design found in most electric motors today. Its innovative structure uses thin, disc shaped rotors that minimize both size and weight while significantly improving efficiency.
Key design advantages include:
Compact and lightweight structure that simplifies installation across different vehicle types.
Slim disc shaped rotors that deliver balanced torque distribution and smooth rotation stability.
Advanced cooling system that maintains consistent high performance without excessive heat buildup.
Use of common, non rare materials to reduce production costs and enable large scale manufacturing.
This innovation is not just theoretical but fully operational. YASA confirmed that the motor is already running in testing facilities at its Oxfordshire plant in the United Kingdom, demonstrating its readiness for future mass production.
From Concept to Commercial Reality
According to Tim Woolmer, YASA’s founder and chief technical officer, the new motor is not a prototype or experimental idea but a commercially viable product built using scalable manufacturing techniques and without relying on rare or expensive materials. The goal is to deliver an advanced electric power unit that combines exceptional performance with economic efficiency.
This approach reflects Mercedes Benz’s long term commitment to sustainability, aiming to reduce vehicle weight and emissions while preserving the brand’s signature performance DNA. Integrating the YASA motor into upcoming production models will give Mercedes a clear competitive advantage in the growing high performance electric vehicle market.
Mercedes and Yasa Collaboration Paving the Way for a New Generation of AMG
Since Mercedes acquired Yasa in 2021, the two companies have been working together to develop a new generation of ultra high performance electric motors that will power future AMG models. Early reports suggest that the first vehicle to feature this groundbreaking technology will be an all electric super sedan carrying the AMG badge, marking the world’s first production car to utilize this type of axial flux motor.
According to current projections, Mercedes plans to implement this technology before the end of the decade. This means performance enthusiasts can soon expect AMG electric cars that deliver over 1000 horsepower, while offering significantly lighter weight and far greater efficiency than any of their competitors.
