GAC says a motor with an ultra-thin amorphous stator core adds 30–50 km of range from the same battery pack, and the Chinese-market Aion models carrying it now span three nameplates. The work behind the design has taken the top honour at the 51st International Exhibition of Inventions Geneva — the Gold Medal with the Congratulations of the Jury, an award the exhibition requires a unanimous jury vote to bestow among its gold medal winners.

The technology targets a specific loss point in EV drivetrains: energy dissipated inside the motor's stator core. According to GAC, the ultra-thin amorphous material cuts those internal losses, leaving more of the battery's energy to turn the wheels. The automaker did not name the partner it worked with on the project, which covers precision manufacturing of low-loss stator cores — a gap worth noting, since amorphous and nanocrystalline stator cores remain a niche, process-intensive field where supplier capability determines scale.

The efficiency numbers GAC cites are the hardest data in the announcement. The Quark Electric Drive 2.0 motor peaks at 99.03% efficiency, and the full drive system scores 94.184% under the China Light-Duty Vehicle Test Cycle (CLTC). Motor-level figures above 99% are rare; the system-level CLTC result is the more meaningful benchmark, since it captures the combined losses of motor, inverter and reduction gear as buyers experience them.

GAC has started fitting the motor to Chinese-market Aion models. It already features in the Aion N60, the 2027 Aion RT and the 2027 Aion i60, and GAC says it plans to expand fitment to more models as output rises. That phrasing — "as output rises" — reads as the key qualifier: amorphous stator cores are harder to mass-produce than conventional silicon-steel laminations, and GAC gave no volumes, no production ramp timeline and no plant details to anchor the rollout.

The commercial logic is straightforward. Gaining range from the motor gives GAC a lever that does not depend on fitting larger, costlier battery packs. In China's crowded EV market, range and price are fought over closely, and every kilometre extracted from the drivetrain rather than the battery is a kilometre that doesn't add pack cost, weight or charging time. A 30–50 km gain at the motor level, if it holds in real-world conditions, could offset a meaningful slice of battery content.

Buyers and analysts should treat that range figure cautiously. GAC provided no baseline vehicle, no test cycle for the range claim itself and no cost data. The 30–50 km figure is the automaker's own claim, announced alongside a prize win, not an independently verified result. The distinction matters: the CLTC drive-system efficiency of 94.184% is a standardized figure, while the range delta is an OEM assertion without stated test conditions.

What to watch next: whether GAC names its stator-core manufacturing partner, whether fitment extends beyond the three current Aion models into volume segments, and whether the company publishes a validated range baseline. The Geneva prize — decided by unanimous jury vote — is a credential, not a production milestone. The real test is output: how many amorphous-stator motors GAC can build, and at what cost, as it pushes the technology across the Aion line-up.
