Byd Xuanji A3, 4-nanometre chip to zero road accidents
The system also supports level 3 and 4 autonomous driving
Byd has unveiled the Xuanji A3, the first 4-nanometer assisted driving chip entirely developed in-house and already in production. The long-term goal, declared by the Chinese manufacturer, is to achieve zero-accident traffic, directly challenging domestic rivals (Nio, Xpeng and Li Auto) and global tech biggies such as Nvidia. The new processor offers a single computing power of 700 Tops (aligning with the Nvidia Drive Thor chip) and is structured to support Level 3 and 4 autonomous driving systems, paving the way for the brand's future robotaxi fleets.
Rather than mere power, Byd focused on hardware-software integration, doubling the efficiency of power utilisation and ensuring compatibility with the new 1,000-line Lidar sensors, capable of millimetre accuracy superior to competing systems. President Wang Chuanfu announced that the system based on the new chip, called DiPilot 300, will be progressively integrated into all Group models. To push the spread of intelligent driving and support sales volumes in the domestic market, Byd will also offer the technology on entry-level cars as an optional extra at the competitive cost of 12,000 yuan (about USD 1,770).
