The Evolution of the BYD Dolphin and Seagull: From Compact EV Pioneer to Global Urban Mobility Leader
The rapid rise of affordable electric vehicles has reshaped the global automotive industry, and few models embody this transformation better than the BYD Dolphin and its smaller sibling, the BYD Seagull (also known globally as the Dolphin Mini or Dolphin Surf). Since 2021, these vehicles have evolved into some of the most influential compact EVs in the world, combining practicality, technology, and affordability.
This article traces the evolution of both models, detailing their production years, trim levels, major updates, and their growing global impact.
Origins of the BYD Dolphin (2021–Present)
The BYD Dolphin entered production in 2021 and remains in production today, marking a major turning point for BYD’s “Ocean Series” lineup.
First previewed as the EA1 Concept at Auto Shanghai 2021, the Dolphin introduced:
- BYD’s e-Platform 3.0
