What to check
Key Facts for Used Buyers
Degradation Tier: R — Under Review
The BYD Yangwang U8 (2024) scores R-Tier for battery longevity. The transparency score of 53% tells you how honest the manufacturer range claim is at real highway speeds.
Real vs. EPA Range
At a steady 65 mph on the highway, the BYD Yangwang U8 (2024) delivers approximately 199 mi of real range, compared to the 373 mi EPA figure.
Winter Range
In cold conditions (around −10°C / 14°F), expect range to drop to around 153 mi — computed via our physics engine, not a flat percentage.
Charging History Matters
Frequent DC fast charging and consistent high-SOC storage accelerate NMC degradation. Ask about charging habits or request a battery health report from the manufacturer's app.

Common questions
FAQ — Used BYD Yangwang U8 (2024)
How much range does a used BYD Yangwang U8 (2024) actually get?
At a steady 65 mph on the highway, the BYD Yangwang U8 (2024) delivers approximately 199 miles of real range, based on its actual drag coefficient, weight, and battery capacity — compared to the 373 mi WLTP claim.
What mileage is too high for a used BYD Yangwang U8 (2024)?
Mileage alone is not the deciding factor for EVs. A well-managed 120,000-mile BYD Yangwang U8 (2024) can outperform a 40,000-mile example with poor charging habits. Run our SOH audit to get the real picture.
How does the transparency score work?
The score is: Real Range ÷ WLTP claim × 100. For the BYD Yangwang U8 (2024), that's 199 ÷ 373 × 100 = 53%. Above 85% = relatively honest. Below 75% = significantly optimistic official claim.
What is the winter range of a used BYD Yangwang U8 (2024)?
In cold conditions around −10°C / 14°F, the BYD Yangwang U8 (2024) is estimated to deliver approximately 153 miles — computed via our V5.7 physics engine accounting for thermal battery losses and increased HVAC demand.
