BYD Builds Its Chip from Scratch: XUANJI A3 Promises 2,100 TOPS and Sends a Clear Signal to the Industry
BYD has announced the Driving SoC XUANJI A3, an internally developed chip for intelligent driving manufactured using a 4-nanometer production process. The presentation took place at the Intelligence Strategy Launch Event, where the manufacturer outlined the next steps in its roadmap for Intelligent Driving Assistance.
The new SoC is designed to offer high computing capabilities in processing data from sensors in advanced driver assistance systems. In the three-chip configuration, the platform can deliver an aggregated computing power of over 2,100 TOPS (Trillion Operations Per Second), a figure that positions the system among the most performant solutions currently announced in the automotive segment. Compared to previous generations, the XUANJI A3 promises improvements in energy efficiency and the ability to manage complex driving scenarios, critical elements for the reliable operation of ADAS systems under real conditions.
The announcement is part of a broader strategy called "Intelligent Driving for All," with which BYD aims to progressively extend driving assistance technologies to an increasing number of models in its range. The stated approach is to make advanced systems - currently mainly available on high-end models - accessible on lower segment vehicles, with the goal of enhancing the overall safety of the vehicle fleet.
On the software and system front, the God's Eye - BYD Driver Assistance System receives an update based on the XUANJI 2.0 architecture, which incorporates next-generation sensors, more advanced AI models, and a continuous learning mechanism defined as data flywheel: the system leverages real usage data collected from the BYD fleet already equipped with intelligent driving technologies to progressively refine its predictive and responsive capabilities.
Among the features enabled by God's Eye are Urban Navigate on Autopilot - semi-autonomous driving in urban contexts - and Intelligent Parking. For these functionalities, BYD has announced a dedicated coverage form in the Chinese market, confirming the manufacturer’s confidence in its technologies. It is worth noting that this initiative is currently limited to China, where such systems operate in specific regulatory and infrastructural contexts. For the European market, the eventual introduction of similar services will depend on homologation timelines, local regulations, and market conditions in individual countries.
Inside the cabin, BYD reaffirmed the positioning of the DiLink AI Intelligent Cockpit as an integrated smart interface capable of proactively managing onboard functions and services through the integration of AI models. The stated aim is to make the human-vehicle interaction more natural and contextual, thereby reducing the cognitive load on the driver.
From a strategic perspective, the announcement of the XUANJI A3 chip consolidates BYD's vertical development model: the Chinese manufacturer internally controls the entire value chain, from the chemistry of the Blade Battery cells to semiconductor design, and up to software integration. This approach - not dissimilar from that adopted by other major tech players like Apple in the consumer sector - allows BYD to reduce dependencies on third-party suppliers, accelerate development cycles, and optimize integration between proprietary hardware and software.
