GAC has begun producing its Quark Electric Drive 2.0 in Guangzhou, China. The system uses an amorphous-alloy stator and a carbon-fiber sleeve around the rotor, and has recorded peak efficiency of 99.03% in testing certified by the China Automotive Engineering Research Institute. GAC says the motor is already being fitted to some of its vehicles.
The company estimates that the technology reduces vehicle energy consumption by around 4%, adding 30–50 km of CLTC driving range with the same battery capacity. An approximate conversion in the source puts the gain at 25–42 km under WLTP, though actual results would depend on the vehicle and how it is used. The integrated 12-in-1 drive unit is rated at 94.184% efficiency under CLTC conditions, has a power density of 17.29 kW/kg and can reach 30,000 rpm.
The stator uses magnetic-alloy ribbons just 0.025 mm thick instead of conventional silicon-steel laminations. GAC reports iron-core losses of 5.7 W/kg, about half the level cited for ultra-thin silicon steel. To manage forces at high rotational speeds, the rotor is wrapped in a 1 mm carbon-fiber composite sleeve. GAC developed automated equipment to process and stack the delicate stator material.
GAC subsidiary RuiPai Powertrain Technology makes Quark 2.0 on an automated line with annual capacity of 100,000 units. The amorphous-alloy and carbon-fiber technology is in series production for Hyptec and Aion models, including the Aion i60 2027. The project, developed with nine other organizations, received first prize at the China Society of Automotive Engineers’ 2026 Science and Technology Awards in Suzhou. Nio’s 925-volt continuous-wave winding system received the same distinction.
