Today, a video has emerged showcasing a camouflaged vehicle undergoing tests at a location labeled as the "Thousand-Step Staircase of Tianmenshan Mountain." The vehicle, shrouded in camouflage film, effortlessly ascended the staircase, with the display screen indicating "Test No. 1289." The stairs at this site measure approximately 15 to 20 centimeters in height, have a depth of around 25 to 30 centimeters, and boast a slope exceeding 35 degrees. Some users argue that this self-constructed scenario testing not only safeguards the environment and cultural relics but also thoroughly evaluates product performance. Last November, Chery Fulwin X3L's unsuccessful attempt to climb the Tianmenshan Mountain stairs stirred up controversy. Judging from the details, the camouflaged vehicle aligns with the features of the current Yangwang U8 model, featuring more rounded wheel arches. BYD is set to host a technical launch event on March 5 to unveil the 2026 editions of the Yangwang U7, U8, and U8L models.
