All 22 Dolphin trims

Every trim in the catalogue with its homologation model code, powertrain, Chinese list price (converted to US$) and sales status. Select a trim for its full specification and parts list. Prices are Chinese domestic manufacturer guide prices, converted to US dollars at 1 US$ = ¥7.10 for orientation only — they are not export prices or local-market prices. Identifying codes — homologation model codes, motor and engine codes, manufacturer and supplier names — are published with their tail masked, so a build can still be matched without republishing the full record.

Two ways to identify a Dolphin part

Frequently asked questions

How do I find the right part for a BYD Dolphin?
The safest route is the VIN. The VIN resolves the exact BYD Dolphin model year, trim and market build — which matters because charging inlets, lamps and some body panels differ between China-market cars and exports. If you already have the part in your hand, read the number off it and use the part-number lookup instead.
Which model years of the Dolphin does EVcoder cover?
Model years 2021 to 2025, across 4 model years — 22 trims in total, all listed on this page with their homologation model codes.
What is the homologation model code for a BYD Dolphin?
Every trim is listed with its MIIT homologation model code, for example BYD7******. That code is the fastest way to match a Chinese-market car to the correct parts list, especially for workshops outside China.
Are export and China-market Dolphin parts the same?
Not always. BYD Dolphin parts can differ by market and model year. Charging inlets, lighting units, instrument clusters and some body panels are market-specific. Always confirm against the VIN before ordering.
Can I get Dolphin spare parts by OEM part number?
Yes. EVcoder cross-references Dolphin part numbers to fitment, supersessions and alternative numbers, so a number read off an old component still resolves to a currently available part.
