Xiaomi priced Pengcheng N90 Max and N70 Max at 299,900 yuan and 259,900 yuan on
July 30, marking its entry into the range‑extended segment. The Pengcheng series
reshapes Xiaomi’s battery sourcing—previous SU7 and YU7 models relied mainly on
CATL and Fudi—bringing Sunwoda and Zhongchuang Xinhang into the supplier mix.
The N90 Max is fitted with a 76kWh ternary lithium pack from Zhongchuang
Xinhang, rated for up to 505 km CLTC pure‑electric range; Zhongchuang Xinhang
remains embroidered in an unresolved 177Ah battery‑quality dispute.
