The BYD Yuan UP boasts a clean and contemporary design. The front fascia features the brand's signature grille, flanked by sleek LED headlights that enhance its modern appeal. At the rear, a distinctive full-width LED light bar provides a unique signature, aligning perfectly with mainstream consumer tastes.

Inside, the cabin is centered around a 10.1-inch central touchscreen and an 8.8-inch digital instrument cluster. It is powered by BYD's advanced smart cockpit system—the DiLink 100—which supports a dual-mode interface for maps and wallpapers, 3D vehicle control, and full-scenario intelligent voice recognition. Additional features include ONE ID identity system, an application store, 5G connectivity, remote control via a smartphone app, and Over-The-Air (OTA) updates.

On the driver-assistance front, the Yuan UP (excluding the base trim) is equipped with the "Divine Eye" C-ADAS (DiPilot 100). This sophisticated system utilizes a suite of 29 sensors, comprising 5 high-precision millimeter-wave radars, 12 ultrasonic radars, and 12 high-definition cameras. Key functionalities include highway assist, intelligent parking, and automatic emergency braking.
