Tech Stack Breakthroughs

1. Hardware Democratization:
   • Horizon Robotics’ Journey 6 chip delivers 512 TOPS at $200, enabling L2+ systems in sub-$25,000 EVs.
   • Hesai’s AT512 lidar (¥6,000/$830) cuts costs by 60%, driving adoption in mid-market brands like NETA and Leapmotor.
2. AI-Driven Software:
   • Huawei’s ADS 3.0 uses multimodal sensors and road topology prediction, reducing reliance on HD maps.
   • Tesla’s FSD V12.5 in China learns from 10 billion+ video frames, optimizing for chaotic traffic scenarios.

Regulatory Milestones

• Beijing: Approved Baidu’s fully driverless robotaxis (no safety operator) in 60km² zones.
• Shenzhen: Legally defines L4 liability—OEMs bear 90% responsibility in system-failure accidents.

Case Study: XPeng’s XNGP

XPeng’s XNGP system now covers 200+ Chinese cities, using crowdsourced data from 500,000 vehicles. Key metrics:

• 85% reduction in manual interventions vs. 2023.
• 40% shorter route planning time via neural network compression.

SinoEVHub Insight:

“Autonomous driving is no longer a premium feature—it’s becoming a baseline expectation.”
