BYD debuts China's most advanced EV chip in smart-driving push

BYD debuts China's most advanced EV chip in smart-driving push BYD on Thursday unveiled what it calls China's first automotive-grade 4-nanometer chip for self-driving cars. BYD, the world's largest electric vehicle maker, unveiled a series of technology advances, including what it calls China's first automotive-grade 4-nanometer chip for self-driving cars. The semiconductor breakthrough approaches the lead of Chinese tech giant Huawei Technologies, which currently makes chips with a geometry of 7 nm but has pledged to debut 1.4 nm chips by 2031. It's designed to allow BYD's computer-assisted driving to stand out from a crowded Chinese EV market that includes rivals such as Xpeng and Xiaomi. Facing eight months in a row of falling sales and intense competition for more advanced charging and intelligent driving technologies, BYD is looking to spark more demand for its vehicles.
