DIRECT ANSWER
Make the decision from one identified vehicle.
A cold dashboard vent does not prove even cabin cooling after sun soak or stable operation under traffic, road and charging load. Record the environment, test every available zone and keep cabin comfort separate from engine, inverter and battery thermal evidence.
Turn model-level information into candidate-level proof. Market terminology can overlap while hardware and legal identity differ, so preserve the original name, VIN, production timing and powertrain beside every translated description. A comparison is credible only when unknowns remain labelled as unknowns.
CONNECTED DECISIONS
Use the evidence in its wider route
- Use the passenger case from the family and cabin-use assessment.
- Keep cabin comfort separate from the DM-i cooling and inverter route.
- Price climate service through the destination maintenance plan.
EVIDENCE FILE
Records that change the answer
Start with ambient and cabin temperature record and link it to the VIN before accepting translated trim names or catalogue photographs. Add control and airflow map so condition or equipment claims can be checked against the actual car. The remaining records establish how the vehicle operates, how it has been treated and whether the proposed route is credible.
- ambient and cabin temperature record
- control and airflow map
- DM-i or EV energy-state and route log
- fault, odor, drainage and physical inspection
- destination refrigerant, diagnostic and parts plan
Record provenance matters as much as the file itself. Link images, scans, measurements and quotations to their source, date and vehicle. If custody changes or the seller substitutes stock, repeat the checks affected by that change instead of assuming the earlier result still applies.
DECISION TEST
Test the route, not the brochure
Compare two candidates from a similar sun-soak condition with the same requested settings and passenger load. Record time to useful comfort at front and rear seating, energy demand, engine intervention on DM-i and any warning or odor after the road segment. Do not compare a pre-cooled showroom car with an outdoor vehicle.
Score evidence strength before scoring price. A transparent candidate with a disclosed preparation item may be safer than a cheaper listing whose identity, history or route compatibility cannot be reproduced for the buyer.
Inspection scope should follow the decision. For this route, check define a repeatable heat-soak baseline, then test controls, fan speeds, vents, recirculation and demist. Continue with observe climate behavior at idle, low speed and steady road load and record inspect filters, drains, condenser area, warnings and operating data. Measurements, photographs, diagnostics and test conditions are more transferable than labels such as “excellent,” “full option” or “export ready.”
Risk boundary
A fixed cooling time or range penalty ignores solar load, temperature, glazing, passengers, settings, route and exact thermal hardware. Topping up refrigerant without leak diagnosis can hide a fault and does not establish correct service.
Do not confuse acceptance with optimism. Write the limitation, likely outcome, remedy, responsible party and allowance into the decision record. Leave purchase approval conditional when the evidence needed to narrow the risk is still obtainable.
DESTINATION CONTROL
Carry the same facts through export
Include filter, refrigerant, diagnostics and component availability in the destination maintenance plan. Record tested settings and unresolved seasonal functions before loading; transport handover is not a future performance guarantee.
Align commercial, customs and transport language before the vehicle enters inland logistics. The destination must accept the actual class and the carrier must receive the correct energy declaration. Registration, insurance and local roadworthiness remain separate checks after customs.
Calculate from a named starting price to a named destination state. Show inspection, repair, inland handling, ocean freight, cover, border charges, compliance, delay allowance and local delivery separately, using a range where the responsible provider has not issued a firm figure.
BUYER QUESTIONS
Questions to settle before payment
Does one cold vent prove the whole system works?
No. Test controls, airflow zones and realistic conditions.
Does cabin cooling prove battery thermal health?
No. Cabin and powertrain thermal systems need separate evidence.
Can DM-i and EV energy impact be treated alike?
No. Identify propulsion and record the actual operating state.

Verify the current market version
BYD lists the current China-market vehicle through separate official Sealion 06 EV and Sealion 06 DM-i pages. Official pages describe the model family; the candidate still needs VIN-linked verification, and destination rules require separate confirmation.
