BYD Sea Lion & BYD Seagull EVs to follow the Dolphin – Report [Update]

Update: ‘Second-gen BYD Blade battery’ section added.

In 2021, Warren Buffet-backed BYD launched the Dolphin as the first model to adopt the marine design concept. A report from suggests that the company is working on three new marine-themed models for 2022: BYD Seal, BYD Sea Lion, and BYD Seagull. Allegedly leaked material floating on Chinese portals reveals several details about these future BYD electric car models.

BYD Seagull

The BYD Seagull (codename: BYD EQ) will belong to China’s A00+ car segment. With prices falling between CNY 60,000 and 80,000 (EUR 8,319-11,092), this model will target EV customers with a tight budget. The BYD Seagull will arrive in the second quarter of the year (April-June 2022), as per the report.

BYD Sea Lion

The BYD Sea Lion (codename: BYD UX) will follow in the third quarter (July-September 2022). It will reportedly be an SUV competing with the Tesla Model Y, which puts it above the Yuan Plus within the BYD lineup. The mid-size electric SUV will cost between CNY 200,000 and 250,000 (EUR 27,731-34,664). It could have plenty in common with the BYD Seal, an upcoming electric midsize sedan that is likely to compete with the Tesla Model 3, Xpeng P5, and Nio ET5. Expect the Sea Lion to also come fitted with the BYD Blade battery.

Recent Chinese reports, based on details observed in a spy picture (view on Twitter), say that the BYD Sea Lion could be the production version of the BYD X Dream concept (pictured above) that debuted at Auto China 2021. BYD said during the presentation that the concept features the brand’s “well-received” Dragon Face design language and uses Chinese knot elements, which will be a key feature on the design front on future vehicles.

Expect the BYD Sea Lion to feature a similar octagonal faux grille, sharp rectangular headlamps, bow-shaped sleek and elegant greenhouse, beefy wheel arches, and a crossover-typical hunched rear-end. The interior should be minimalist but more practical and realistic than that of the concept. Expect certain similarities with the Dolphin and Yuan Plus in the cabin.

BYD Seal

Internally called BYD EK, the BYD Seal will be 4,770 mm long, 1,860 mm wide, and 1,460 mm tall, and its wheelbase will measure 2,900 mm, as per Chinese portals. It will share the e-Platform 3.0 with the Dolphin. BYD will offer it with an 800-volt battery pack that provides it a range of up to 700 km. The electric sedan may come in RWD and AWD variants, with the latter allowing a quick 0-100 km/h acceleration time of just over 3 seconds (3.3 or 3.4 seconds). The RWD variant will be available with two motor options: 150 kW and 180 kW. The AWD variant will sport two motors, one producing 200 kW and one producing 160 kW, reports said.

The BYD Seal will hit the company’s domestic market in the current quarter (January-March 2022). Prices will fall in the CNY 150,000-200,000 (EUR 20,798-27,731) bracket.

Second-gen BYD Blade battery

It is reported that BYD is developing second-generation Blade battery with a high energy density of 180 Wh/kg, a significant improvement over the current Blade battery with an energy density of 150 Wh/kg. That, along with a fifth-generation chip, will reduce power consumption in BYD EVs by 20%, increase the driving range by 3%, while offering an increase in motor power and torque. That’s according to an article from, which also claims that the next-gen BYD blade battery is very likely to debut in one of the BYD Ocean series models (BYD Sea Lion, BYD Seagull, BYD Seal, etc.). Note that BYD has issued no updates on the evolution of the Blade battery.
