Behind AITO M9's Live Range Test: A Calculated Play in the Chengdu-Chongqing Twin Cities

I noticed an interesting detail: HarmonyOS Intelligent Mobility chose the Chengdu-Chongqing round trip route for the first pure-electric range test of the AITO M9. Not the common Beijing Sixth Ring Road, nor the Shanghai Outer Ring, but Chengdu to Chongqing—a "devil's course" defined by mountain cities, tunnels, steep climbs, and frequent acceleration/deceleration. This round trip is roughly 600 km, hitting right on the "psychological threshold" for pure-electric vehicles—slightly lower than the CLTC rated range, but no one dares to guarantee actual driving performance.
