The BYD Sea Lion 07 and the BYD Seal (also called Atto 4 in some markets) are both electric SUVs from BYD’s Ocean series. Sea Lion 07 is a mid‑size SUV aimed at buyers who want spacious cabin, family utility, and long range. Seal is a sportier crossover‑style SUV aimed at drivers who want quicker acceleration, agile handling, and tech in a slightly smaller package.
Range differs by layout and battery. Sea Lion 07 delivers up to about 610 km CLTC on long‑range versions, which translates to strong real‑world range for trips and daily travel. Seal offers up to roughly 560 km CLTC, giving slightly lower range due to its sportier tuning and aerodynamics. Charging speeds are close: both support DC fast charging around 150 kW, allowing 10–80% fills in roughly 25–35 minutes under good conditions, with Sea Lion 07 sometimes showing quicker mid‑range gains due to battery chemistry.

Price positions Sea Lion 07 above Seal in most markets because of its larger size and family focus. Seal sits slightly lower, reflecting its sport‑oriented package and compact footprint. Availability overlaps in China and select export markets, with Seal reaching wider Europe and Sea Lion 07 rolling out in key regions. This comparison helps you weigh range and interior space against performance and agility in a BYD SUV.
Within BYD’s Ocean series, Sea Lion 07 sits near the top of the SUV range, alongside the BYD Atto 3 and larger BYD Tang. Seal sits slightly below Sea Lion 07 and near models like the BYD Dolphin and BYD Seal U, creating a ladder from compact crossovers to larger SUVs within the brand.
BYD Sea Lion 07 offers longer range, spacious interior, and strong family utility, but its larger size can feel less nimble and it costs more. BYD Seal offers quicker acceleration, more agile handling, and lower entry price, but its range is slightly lower and cargo space is smaller.
QUICK VERDICT; Pick BYD Sea Lion 07 if you want maximum range and interior space. Pick BYD Seal if you want a sportier drive and lower price.
