Overview
- The 12.7 kg prototype reached a 750 kW short‑term peak on company dynamometers, a 40% jump over YASA’s prior 42 kW/kg benchmark from a 13.1 kg unit.
- YASA estimates continuous output at 350–400 kW, equating to roughly 27.6 kW/kg in sustained operation pending extended testing.
- Executives say the motor achieves its power density through axial‑flux design, advanced thermal management and compact packaging rather than exotic materials.
- The company asserts the architecture is scalable for high‑performance automotive use and claims roughly triple the performance density of leading radial‑flux motors.
- The record remains unofficial without third‑party certification, media outlets have reported the results, and YASA—owned by Mercedes‑Benz—has not given a production timeframe.
