GAC's Amorphous Stator Motor Takes Top Prize at Geneva Inventions Expo — and It's Already in Showrooms

GAC has begun installing a new kind of electric motor in Aion models sold in China, and the design behind it has just landed the highest honor at the 51st International Exhibition of Inventions Geneva. The unit uses an ultra-thin amorphous material for its stator core, an approach the automaker credits with squeezing an extra 30–50 km of driving range out of an unchanged battery pack.

The award — a Gold Medal with the Congratulations of the Jury — is reserved for a single entry chosen by unanimous vote from among the fair’s gold medalists. GAC has not disclosed which partner collaborated on the project, which centers on precision manufacturing of low-loss stator cores. The company claims the material reduces energy wasted inside the motor, so more of it reaches the wheels. Its Quark Electric Drive 2.0 motor is rated at a peak 99.03% efficiency, while the complete drive system posts 94.184% under China’s Light-Duty Vehicle Test Cycle.

For GAC, the appeal is strategic: extracting range from the motor rather than the battery gives the company a cost lever in a domestic EV market where range and sticker price are dissected down to the decimal. The motor is already fitted to the Aion N60, the 2027 Aion RT and the 2027 Aion i60, with more models slated to receive it as production capacity grows. GAC has not shared volume targets, pricing implications or a baseline for its range figure.
