BYD’s ultra-luxury sub-brand Yangwang has rolled out a major over-the-air update for the U7 flagship sedan, pushing the EV version to firmware V2.3.0 and the PHEV variant to V2.3.1. The update covers four pillars — intelligent security, smart cockpit, smart experience, and ultimate driving control — adding 22 new features alongside 16 functional optimizations.
Intelligent Security: Sentinel Mode Upgraded
Two notable enhancements headline the security pillar. First, the Sentinel Mode now supports cloud-based transmission of high-risk video clips. When a high-risk alarm is triggered, the captured video automatically uploads to the cloud, allowing owners to view and download the past seven days of footage via the BYD or Yangwang mobile app.
Second, evidence video export has been simplified. Owners can now export incident footage locally or to a USB drive, with high-speed Wi-Fi transfer also available for direct phone export — a meaningful upgrade for anyone who has needed to share dashcam evidence with insurance or law enforcement.
Smart Cockpit: AI Agent for Daily Life
The cockpit update introduces several lifestyle-focused features powered by an integrated AI agent:
- Restaurant Queue Agent: Pull up to a popular restaurant and the system automatically prompts you to join the queue — one tap (or a voice command in advance) puts you on the waitlist.
- Smart Ordering Agent: Voice-order popular drinks like Starbucks, complete with in-car face-recognition or no-password payment, then auto-navigate to pickup.
- Concise/Standard Voice Modes: Switch the voice assistant to concise mode for shorter, less intrusive responses.
- Voice-Activated Issue Reporting: Wake the voice assistant and verbally report driver-assistance issues directly.
- Voice Control of Exterior Mirrors: Adjust non-streaming mirrors hands-free.
- Phone Network Sharing: New cross-device tethering with select OPPO, OnePlus, Realme, vivo, iQOO, Xiaomi and Redmi handsets keeps the car connected while phone mirroring stays active.
Smart Experience: From Karaoke to UWB Door Entry
The U7’s infotainment system also gains several creature-comfort additions: an iQiyi audio-only mode, a new “Light of the Summit” wallpaper inspired by the golden glow on snow-capped peaks, expanded IoT voice control for smart child seats and massage devices, and UWB tap-to-unlock — double-tap the door to enter, no key required. A new four-mode music dancing routine and refined “shake-to-greet” unlock animations round out the cabin experience.
Ultimate Driving: Crab Walk Joins the Arsenal
The headline driving upgrade is BYD’s new Smart Crab Walk. Leveraging the U7’s four-motor architecture and rear-wheel steering, the car can now move diagonally to slip in and out of tight parking spaces or extricate itself from rough terrain — a feature normally reserved for off-road specialists like the GMC Hummer EV.
A new 2D/3D switchable display also clearly visualizes suspension geometry, wheel angles and body posture in real time, giving drivers an instant readout of vehicle dynamics. For context on Yangwang’s previous flagship OTA, see our coverage of the Yangwang U9 comprehensive OTA update.
Pricing and Positioning
The Yangwang U7 currently lists between 628,000 and 888,000 yuan (approximately $86,660 – $122,540 USD), positioning it as a direct competitor to the Mercedes-AMG EQS and Porsche Taycan Turbo in the Chinese ultra-luxury segment.
Frequently Asked Questions
What firmware versions are included in this Yangwang U7 OTA?
The EV variant updates to V2.3.0, while the PHEV (range-extender) variant moves to V2.3.1. Both share the same 22 new features and 16 optimizations.
Is the Smart Crab Walk feature unique to Yangwang?
Yangwang is one of the first Chinese OEMs to offer four-motor crab-walk capability in a flagship sedan. Competing functions exist on dedicated off-road EVs, but few sedans can match this level of low-speed maneuverability.
How do I install the V2.3 OTA update?
The OTA push happens automatically when the vehicle is connected to Wi-Fi or 4G/5G. Owners can also manually check for updates via the in-car settings menu.
Does the new Sentinel Mode upload all videos?
No. Only videos triggered by high-risk alarms are auto-uploaded to the cloud, preserving bandwidth and privacy. Users can browse or download the past seven days of clips through the official app.
