What to check
Key Facts for Used Buyers
Degradation Tier: A — Above Average
The BYD Tang EV (2023) scores A-Tier for battery longevity. The transparency score of 97% 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 Tang EV (2023) delivers approximately 242 mi of real range, compared to the 249 mi EPA figure.
Winter Range
In cold conditions (around −10°C / 14°F), expect range to drop to around 184 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 Tang EV (2023)
How much range does a used BYD Tang EV (2023) actually get?
At a steady 65 mph on the highway, the BYD Tang EV (2023) delivers approximately 242 miles of real range, based on its actual drag coefficient, weight, and battery capacity — compared to the 249 mi WLTP claim.
What mileage is too high for a used BYD Tang EV (2023)?
Mileage alone is not the deciding factor for EVs. A well-managed 120,000-mile BYD Tang EV (2023) 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 Tang EV (2023), that's 242 ÷ 249 × 100 = 97%. Above 85% = relatively honest. Below 75% = significantly optimistic official claim.
What is the winter range of a used BYD Tang EV (2023)?
In cold conditions around −10°C / 14°F, the BYD Tang EV (2023) is estimated to deliver approximately 184 miles — computed via our V5.7 physics engine accounting for thermal battery losses and increased HVAC demand.
