The Chinese automaker that produces the Seal battery-electric mid-size sedan is BYD Auto.
The BYD Seal is part of BYD’s Ocean Series, a family of vehicles using ocean-themed names and styling. Its design was previewed by the Ocean-X concept in September 2021, and the production model was announced in China in May 2022 before deliveries began that August.
The sedan is built on BYD’s e-Platform 3.0 and uses the company’s Blade lithium-iron-phosphate battery technology. Depending on version, it has rear-wheel drive or dual-motor all-wheel drive, giving the Seal a broad range of performance levels.
A frequent mix-up is confusing the Seal with BYD’s Dolphin, another Ocean Series vehicle. The Dolphin is a smaller hatchback, while the Seal is a mid-size sedan. Geely, XPeng and Nio are also Chinese EV makers, but none produces the BYD Seal.
