In terms of BYD Sea Lion 07 EV appearance, the new car continues the marine aesthetic design concept of Ocean Network. The front face is a closed nose with a sharpness, and the two sides are inlaid with exaggerated "C"-shaped headlights. The lamp cavity integrates double-section "U"-shaped headlights and complex light strips. The front surround is equipped with a large-size trapezoidal lower grille, and the left and right air intakes are dug out with edges and corners. Some models will also integrate laser radar configurations in the air intakes to provide a hardware foundation for the "Eye of God" high-level intelligent driving.

The side of the BYD Sea Lion 07 EV body is a coupe SUV shape similar to BYD Song L. The fastback roof transition is matched with a simple and straight waistline, and the D-pillar also has a special floating design. In terms of details, the hidden door handles and large-size two-color wheels effectively enhance the fashionable attributes, but the framed doors are obviously more economical than Song L. In terms of body size, the length, width and height of the car are 4830/1925/1620 mm respectively, and the wheelbase is 2930 mm.

At the BYD Sea Lion 07 EV rear, the black spoiler at the end of the trunk echoes the roof spoiler, and the through-type taillights below are blackened. The thickened areas on both sides light up to present a fish-scale light source, which is eye-catching. The rear bumper is a large area of ​​black layout, and the "C"-shaped air intake decoration is added on both sides, which greatly enhances the sporty atmosphere.
