📊 Competitor Analysis▸ Show
| Feature | Xiaomi SU7 | Tesla Model 3 | BYD Seal |
|---|---|---|---|
| Chassis | JiaoLong (CDC+Air) | Double Wishbone/Multi-link | Double Wishbone/Multi-link |
| ADAS | 1 LiDAR + 11 Cameras | Vision Only | 1 LiDAR + 11 Cameras |
| EEA | Zonal Controller | Centralized | Domain Controller |
| Pricing (CNY) | ~215,900+ | ~231,900+ | ~175,800+ |
🛠️ Technical Deep Dive
- EEA Architecture: Utilizes a high-speed Ethernet backbone (up to 1Gbps) connecting the zonal controllers to reduce wiring harness weight by approximately 15% compared to traditional CAN-bus architectures.
- Battery Thermal Management: Features a multi-channel liquid cooling system integrated with the heat pump, allowing for rapid pre-conditioning in temperatures as low as -20°C.
- Motor Technology: The 'HyperEngine' V6s motor utilizes a rotor design capable of reaching 21,000 RPM, featuring laser-welded silicon steel sheets for high-speed stability.
