Use this guide to test market-specific specification verification without relying on model reputation or a seller's general description. Every conclusion should survive a change of reviewer.
Decide market-specific specification verification
Official BYD material shows material variation. A Caribbean RHD DM-i sheet lists 4,775 mm length, 2,765 mm wheelbase and an 18.3 kWh battery, while earlier regional sheets and China versions can differ. EV specifications form a separate family.
Evidence for market-specific specification verification
Build a VIN-linked table for body dimensions, weights, battery, motor, engine where fitted, driven wheels, AC/DC limits, connector, tyres, seats and safety equipment. Cite the dated market source for every brochure value.
Export and ownership exposure
Borrowing figures from Sealion 6, another model year or another test cycle can misstate range, charging or equipment. Shipping dimensions should include the actual vehicle and accessories.
Apply the decision to a real candidate
Use official numbers for screening and actual labels and documents for contracting. Destination conformity fields need confirmation from the authority that will accept them.
Build the VIN-linked record
The approval record should show what established market and year, who reviewed dm-i or ev and which evidence supports battery and motor. List missing material explicitly; silence in a report is not a passed test.
Common approval mistakes
Avoid combining different years, markets or powertrains in one informal comparison. Do not turn “not checked” into “working,” and do not let a discount close uncertainty about dimensions and weights or safety equipment.
Close the decision
Finish market-specific specification verification with a pass, hold or reject status. A hold must name the next action for dm-i or ev or dimensions and weights; a rejection should preserve the reason so the next shortlist does not repeat it. Approval means the buyer has consciously accepted any remaining limits, not that every uncertainty disappeared.
Independent review for market-specific specification verification
For market-specific specification verification, assign each approval field to a reviewer with the relevant competence. Record candidate evidence for market and year, dm-i or ev, battery and motor, then obtain destination or commercial confirmation for connector and charging, dimensions and weights, safety equipment where required. Every conclusion should identify its source, date and VIN. If two reviewers interpret a field differently, keep it open until the underlying document, photograph, diagnostic result or written third-party answer resolves the difference.
Arrival controls for market-specific specification verification
Before loading, freeze the accepted VIN, identity, condition, odometer, warning state, keys, accessories and unresolved exceptions. On arrival, compare those records before cleaning, repair, software changes or routine use. Recheck any open item involving connector and charging, dimensions and weights, safety equipment, preserve evidence for a timely carrier or supplier claim, and update the ownership file with actual destination findings and costs.
Compare evidence, not advertisement language
For market-specific specification verification, create two columns: verified candidate facts and unresolved commercial claims. Only the first column may support valuation. Put market and year, dm-i or ev and battery and motor in the verified column only after the source is dated and linked to the VIN. Keep translated trim names and generic market specifications in the second column until reconciled. This method makes a cheaper vehicle with weak evidence visibly different from a properly documented candidate.
Prepare the post-arrival owner file
The final handover pack should be usable by someone who never saw the China-side listing. Include the exact version record, keys, charging hardware, diagnostic baseline, accepted body condition, service evidence and the decisions behind connector and charging and dimensions and weights. Add a first-month action for safety equipment. Clear ownership records reduce duplicated diagnosis, wrong parts orders and disputes over whether an issue existed before shipment.

Official BYD Song Plus DM-i specification ↗Official BYD Sealion 6 specification ↗Buyer questions about market-specific specification verification
What size is the Song Plus?
Many current official DM-i sheets list around 4,775 mm length and a 2,765 mm wheelbase, but verify the exact market version.
Does every Song Plus use an 18.3 kWh battery?
No. Battery capacity varies by powertrain, model year and market.
Can EV data be used for DM-i?
No. Treat them as distinct propulsion and charging specifications.
