On May 28, BYD Song Ultra DM-i officially launched at 129,900-159,900 yuan. The same day, BYD's intelligent strategy conference released the self-developed 4nm process Xuanji A3 AD chip, thousand-line LiDAR, flash capture camera, dual infrared cameras, and a 1-year City Pilot safety commitment, marking BYD's entry into a new phase of intelligent strategy.
Song Ultra DM-i: The Intelligent Driving Popularizer at 129,900 Yuan
The BYD Song Ultra DM-i offers 5 variants priced at 129,900-159,900 yuan. This pricing brings advanced intelligent driving into the sub-150,000 yuan market, accelerating the shift from premium optional feature to mass-market standard equipment.
The vehicle features BYD's 5th-generation DM technology, with CLTC pure electric ranges of 75km and 115km, and combined range exceeding 1,200km. While balancing energy consumption and range, Song Ultra DM-i makes intelligence its core differentiator.
Xuanji A3: China's First Automotive-Grade 4nm AD Chip
The highlight of BYD's intelligent strategy conference was the self-developed Xuanji A3 AD chip. Using 4nm advanced process, it is China's first automotive-grade 4nm AD chip, designed specifically for high-end intelligent driving scenarios.
Xuanji A3's computing power rivals international mainstream AD chips, supporting full-scenario functions including city pilot, highway pilot, and automatic parking. BYD stated Xuanji A3 will equip both Tianyan Eye A and Tianyan Eye B systems, achieving coverage from mainstream to premium segments.
Perception Hardware Matrix: Thousand-Line LiDAR + Dual Infrared Cameras
Beyond the chip, BYD released multiple perception hardware innovations:
- Thousand-line LiDAR: Long detection range, high point cloud density for precise urban perception
- Flash capture camera: High-frame-rate imaging for dynamic target recognition
- Dual infrared cameras: Night and adverse weather perception redundancy
- Tianyan Eye C: Supports 20+ functions including highway pilot, smart parking, and lane-change assist
This perception hardware matrix means BYD no longer relies on external suppliers for AD systems, but has established full-stack self-developed capabilities from chips to algorithms to sensors.
City Pilot Safety Commitment: Building Trust with a 1-Year Guarantee
BYD officially introduced a 1-year City Pilot safety commitment for vehicles equipped with Tianyan Eye A and B. This aims to reduce consumer safety concerns about intelligent driving features and accelerate actual usage rates.
| AD System | Chip | Core Functions | Representative Models |
|---|---|---|---|
| Tianyan Eye A | Xuanji A3 | City pilot + Highway pilot + Auto parking | Han, Tang, Seal |
| Tianyan Eye B | Xuanji A3 | Highway pilot + Auto parking | Song, Qin, Dolphin |
| Tianyan Eye C | Third-party | Highway pilot + Smart parking | Entry models |
BYD's intelligent strategy has direct relevance for overseas buyers. For BYD models exported to Central Asia, Russia, and other markets through platforms like EX1000.COM, the self-controllable AD system means subsequent OTA updates and feature iterations are not constrained by suppliers, ensuring long-term ownership experience.
Market Positioning and Export Implications
At a starting price of 129,900 yuan, Song Ultra DM-i brings high-end AD into the compact SUV market. This aligns with BYD's consistent "technology democratization" approach—rapidly deploying advanced technology to mass markets, then amortizing costs through scale effects.
For Central Asia, Russia, and other markets, BYD's full-stack self-developed capability means:
- AD systems can be customized for local road environments
- No risk of international supplier disruption
- Lower after-sales maintenance and software upgrade costs
