BYD has unveiled the Xuanji A3, China's first automotive-grade 4nm chip delivering 700 TOPS per unit (2,100 TOPS in a three-chip cluster), capable of supporting Level 3 and Level 4 autonomous driving. The chip draws 20% less power than comparable semiconductors and has entered mass production. Alongside the chip, BYD is expanding its God's Eye driver-assistance system to all China models, including the budget $10,300 Seagull hatchback — the first car in its class to feature LiDAR. The upgraded system costs 12,000 yuan as an add-on, and BYD is backing it with accident insurance when engaged. The announcement comes amid eight consecutive months of declining sales, a 55% Q1 profit drop, and intensifying competition from Huawei-backed brands and Xiaomi in China's EV market. BYD's strategy is to shift competition from price to technology, leveraging 3.15 million ADAS-equipped vehicles generating 200 million km of daily driving data to train its algorithms every three days.
