At its Intelligence Strategy Launch Event, BYD revealed a major push in autonomous driving: the Xuanji A3, a self‑developed 4nm automotive driving system-on-chip (SoC), and an industry‑first expansion of its Full Damage Coverage guarantee to the Urban Navigate on Autopilot (NOA) function of its God’s Eye driver assistance suite.
The Xuanji A3 is built on a 4nm node and, in BYD’s configuration, a cluster of three chips delivers more than 2,100 TOPS of combined compute while reportedly consuming about 20% less power per unit of computation than comparable solutions. Architecturally the chip pairs a 3‑core NPU with a 16‑core CPU, delivers 273 GB/s DDR bandwidth, and carries ASIL‑D functional safety certification. BYD says the chip sits at the centre of its new Xuanji Architecture 2.0 platform, which consolidates previously separate vehicle domains—smart cockpit, driver assistance and electric propulsion—into a single, centralised computing stack.
Company statements emphasised integration benefits: BYD claims that co‑optimising the A3 with its in‑house algorithms doubles effective utilisation versus nominal TOPS, and that the total hardware cost for an A3‑based platform runs at roughly one‑third of an equivalent Nvidia Thor solution, according to external analyst commentary cited at the event. BYD also signalled the platform will continue to support third‑party chips during the transition to in‑house silicon.
The chip launch deepens BYD’s vertical integration. The automaker already produces batteries, power semiconductors, motors and vehicle electronics—and operates wafer fabs and a large semiconductor business—so the Xuanji A3 closes the last major gap in BYD’s supply chain independence. The company said advanced fabrication is handled by external foundries (not explicitly named), while BYD retains full‑chain capability across design, packaging and testing.
Beyond silicon, BYD announced a suite of God’s Eye upgrades—Xuanji Architecture 2.0, a “satellite sensor architecture,” a refreshed physical AI large model, and a self‑evolving data flywheel—and rolled out the DiLink AI Intelligent Cockpit with an advanced in‑car agent. The company reiterated plans to invest over RMB100 billion in intelligent driving R&D over the next three years and said God’s Eye LiDAR will be optionally available across its lineup, including mass‑market models.
Full Damage Coverage for Urban NOA
In a move designed to translate technical claims into consumer reassurance, BYD said it is extending a one‑year Full Damage Coverage guarantee to users of Urban NOA who operate the system in compliance with regulations. The policy covers economic losses from legally liable accidents while the Urban NOA function is active; it joins an earlier Full Damage Coverage offer for Intelligent Parking, making BYD the first automaker to provide dual coverage for those ADAS functions, the company said.
BYD frames the pledge on three pillars: a fleet of more than 3.15 million intelligent‑driving‑equipped vehicles supplying real‑world data, what it says is over 124 million miles of daily God’s Eye data for fast algorithm iteration, and a 5,000‑engineer R&D team supporting continuous improvement. The company positions the guarantee as part of a broader “Intelligent Driving for All” strategy aimed at safety goals such as reducing traffic accidents and advancing higher‑level autonomous features.
