On May 29, 2026, BYD officially launched its first self-developed 4-nanometer vehicle-grade intelligent driving chip, achieving a major technological breakthrough in domestic high-end automotive core chips and filling the long-standing technical gap in China’s new energy vehicle industry.
The newly released chip features ultra-high computing power, low power consumption, and extreme operational stability, fully meeting the strict safety and performance standards of vehicle-grade chips. It can adapt to full-scenario advanced assisted driving and fully autonomous driving systems, with comprehensive computing performance reaching the international mainstream leading level. Compared with imported chips, BYD’s self-developed product also has obvious advantages in customized adaptation and cost control for domestic vehicle models.
For a long time, high-end automotive intelligent driving chips have been monopolized by overseas manufacturers, which has become the core bottleneck restricting the independent development of China’s intelligent vehicle industry. The official launch of BYD’s 4nm chip completely breaks the external dependence on foreign high-end vehicle chips, realizing independent controllability of core auto parts.
This technological breakthrough will effectively reduce the overall manufacturing cost of domestic new energy vehicles, enhance the market competitiveness of domestic smart car products, and accelerate the global layout of Chinese new energy vehicle brands. Industry analysts pointed out that the mass production and large-scale application of this chip will drive the iterative upgrading of the domestic automotive chip industrial chain, drive the coordinated development of upstream materials, equipment and downstream vehicle manufacturing, and further consolidate China’s leading position in the global new energy vehicle track.
In the future, BYD will continue to increase R&D investment in automotive chips, power batteries and intelligent vehicle technologies, continuously improve the independent innovation capability of the industrial chain, and lead the high-quality development of China’s intelligent new energy vehicle industry.
