In terms of design, BYD Yuan UP takes the route of fashionable and young design. While continuing the design style of BYD Dynasty family as a whole, it adds many personalized elements of its own.

The front of the car adopts a sealed design, in which the upper part is connected to the LED headlights on both sides with a bright black trim, and the lower part is the lower grille with two geometric chrome trims, and the edges have a shape similar to vents on both sides. The streamlined LED headlights have two L-shaped daytime running lights inside, and there are L-shaped daytime running lights on the lower edge of the headlights. The overall shape is full of modernity.

The waistline of the body is very smooth, and it also adopts a floating roof shape. The black guard plate similar to the front bumper can be clearly seen on the side skirts, and the chrome trim similar to the lower grille of the front is used.

The rear of the car has a large-sized spoiler, with a through-type LED taillight at the bottom. The interior of the lamp cavity on both sides also adopts a design similar to the Chinese knot. The lower surround is equipped with a more exaggerated black guard plate than the front surround, and the bottom is edged with metal chrome.
