BYD Sealion 8, Sealion 08 and Tang: Untangling the Names

The Sealion 8 sold in Australia is a rebadged version of China's Tang L. The Sealion 08 is a different, larger flagship SUV sold in China and not confirmed for Australia. "Tang" is the original Chinese nameplate family behind the Australian car. One zero separates two completely different vehicles.

Nobody has bothered to publish a clean disambiguation of these names, so here it is, anchored to the one document that settles what the Australian car actually is: its own owner's handbook.

The naming problem

BYD runs two naming systems. In China, its mainstream SUVs wear Dynasty names like Tang, Han and Song. For Australia and most export markets, models are renamed into the Ocean convention: Seal, Sealion, Shark, Dolphin. CarsGuide reported the rename directly: the locally delivered Sealion 8 is a rebadged version of the Chinese-market Tang L, renamed to sync with the Australian naming convention.

Then, in late 2025, BYD announced a new China flagship called the Sealion 08, and the confusion became inevitable. Same word, one extra zero, entirely different vehicle.

Sealion 8: what Australia gets

The Australian car is fully documented in its owner's handbook, which is why we can anchor this half of the story precisely. Per the handbook, the Sealion 8 is 5,040 mm long and 1,996 mm wide on a 2,950 mm wheelbase, seats seven, and is a plug-in hybrid: a 1.5-litre turbocharged four-cylinder (BYD472ZQB, 115 kW rated) paired with a 200 kW peak front motor in the DMI configuration, with the DMP adding a 200 kW peak rear motor for what the handbook calls Intelligent 4WD. Kerb weights are 2,315 kg (DMI) and 2,580 kg (DMP).

That is the whole point of the rebadge: mechanically, the Australian Sealion 8 is the Tang L wearing Ocean-series clothes. In some other export markets the very same vehicle is sold as the Atto 8, per CarNewsChina, which means one SUV currently carries three names depending on where you stand.

Sealion 08: the China flagship

The Sealion 08 is a different and larger machine, revealed at the Beijing motor show in April 2026 and rolling out across China. Per CarsGuide and CarExpert reporting: 5,115 mm long, offered with two or three seating rows including a six-independent-seat layout, in EV and PHEV forms. The EV claims up to 900 km on China's CLTC cycle from a second-generation Blade battery, with dual-motor output up to 480 kW and a 4.9-second 0 to 100 km/h time. CarNewsChina predictions cited by CarExpert suggest a 130.5 kWh pack capable of charging from 10 to 97% in as little as nine minutes; treat that as a prediction, not a specification.

It pairs with the Seal 08 sedan as BYD's dual flagship line, aimed at Audi, BMW and Mercedes territory. Nothing about it is confirmed for Australia, and it has no right-hand-drive manual for us to verify against, so every figure above is attributed China-market reporting.

Where the Tang name fits

Tang is the ancestor. The nameplate launched in China in 2015, with the current generation dating to 2018 and a 2022 facelift. The Tang L, launched in 2025, is the newer, larger member of that family, and it is the specific car Australia receives as the Sealion 8, with EV versions in China debuting BYD's megawatt flash-charging technology.

The family keeps growing: a next-generation entry-level Tang was spotted testing in China in June 2026, expected to share the Sealion 8's chassis and interior, and regulatory filings from July 2026 show a restyled Tang L adopting the flagship Great Tang's design language, which is the likely shape of a future Australian Sealion 8 update. What any of these will be called in export markets is genuinely undecided; even CarNewsChina speculates between Atto and Sealion names for the next one.

Why BYD renames for export

Three practical reasons emerge from the reporting. Dynasty names carry cultural weight in China that does not translate abroad. The Ocean convention gives export markets a coherent ladder (bigger number, bigger car) that dealers can sell without a history lesson. And renaming lets BYD position the same hardware differently per market, as the Tang L / Sealion 8 / Atto 8 triple identity shows. The cost is exactly the confusion this article exists to fix, and the "08 versus 8" collision suggests even BYD is now feeling that cost.

Which manual applies to your car

This is the practical takeaway. If you own an Australian Sealion 8, the Sealion 8 Owner's Handbook is your document, and it describes your car completely, from the nameplate below the right B-pillar to the seven-seat layout. Advice you find online for the "Tang L" may broadly apply since it is the same platform, but market specifications differ, so the handbook wins every disagreement. Content about the Sealion 08 does not apply to your car at all, whatever the headline implies, and no right-hand-drive Sealion 08 manual exists.
