BYD unveiled its Xuanji A3 driving chip at its May 28, 2026 technology event. In its official release, BYD describes the chip as self-developed, based on a 4nm process and already in mass production.
The company says the chip supports L3 and L4 driving systems and that a three-chip configuration provides more than 2,100 TOPS. These are manufacturer specifications; they do not establish that every equipped vehicle is approved for unattended driving.
Editorial update, October 8, 2026: This brief was checked against BYD’s announcement and its May 29 English release. Claims of independence from rival chip suppliers and conclusions about export restrictions have been removed. The original article date is retained.
