The first sight of BYD Song L DM-i gives people the feeling that it is the SUV version of Qin L DM-i. The exaggerated hexagonal air intake grille is supplemented with diffused chrome dot matrix elements, and the "C"-shaped air guide grooves on both sides and the swooping front of the car give people a strong visual impact. The bottom trapezoidal lower grille is also decorated with silver guard plates, which adds a lot of muscle power. The rounded and upward headlights are connected by gun-gray trims, which further enhance the visual tension of the front face, and the through-type LED light strip creates a technological atmosphere.

The body size of BYD Song L DM-i is 4780/1898/1670mm in length, width and height respectively, and the wheelbase is 2782mm, which is between BYD Song Pro DM-i and BYD Tang DM-i. The side of the body adopts a more rounded and full style, and the concave lines are added above the square wheel arches, matched with the silver trim on the side skirts, continuing to emphasize the sense of power. The slightly sloping back shape and the "dragon-colored flying wing" waistline create a posture ready to go. The addition of features such as the floating roof, hidden door handles and two-color petal-shaped wheels brings a fashionable and avant-garde attribute.

The full tail shape of BYD Song L DM-i complements the style of the whole vehicle. The large area of ​​smoked black rear surround at the bottom is also outlined with a silver trim, giving people a very solid feeling. In addition, it will also adopt a "streaming knot" through-type taillight group similar to Qin L DM-i. However, BYD Song L DM-i will be decorated with chrome trims and a light-up "BYD" logo, taking into account both the sense of technology and recognition.
