NIO XPENG and BYD Deploy Proprietary Driving Chips While Foreign Supplier Dependence Remains
NIO and XPENG have installed their own intelligent-driving chips in production vehicles, and BYD has begun scaled mass production of its Xuanji A3 chip, though no vehicle model has been named for its use. The shift represents a diversification strategy rather than a full replacement of foreign suppliers: XPENG's president has stated the company will continue partnering primarily with Nvidia. Available evidence does not quantify how many production vehicles carry proprietary chips, what share of compute still comes from foreign sources, or how much export-control exposure has actually changed.
