A black BYD Tang was filmed moving through a flooded street in Shenyang, China, with a large rear drive assembly scraping along the road behind it. The component was still tethered to the SUV by an orange high-voltage cable, creating the extraordinary impression that the electric vehicle<\/a> had dropped its motor while driving.<\/p>\n\n\n\n

The motor did detach, but BYD says it did not fall out because of an ordinary manufacturing failure. According to the automaker, the SUV suffered a severe underbody strike against an obstacle hidden by floodwater, a distinction that turns the viral clip into a warning about extreme rain, road visibility, and the limits of vehicle waterproofing.<\/p>\n\n\n\n

A motor really did come loose<\/h2>\n\n\n\n

The incident unfolded as heavy rain caused widespread waterlogging across Shenyang. During the wider storm, a red rainstorm warning in Hunnan District reported roughly 2 to 7.5 inches of rainfall and warned that another 4 to 6 inches could fall within three to five hours.<\/p>\n\n\n\n

Videos show the Tang with its hazard lights on and the rear motor assembly hanging beneath the body before dragging across the flooded pavement<\/a>. The clips do not show the moment of impact, the obstacle, or the condition of the road below the brown water.<\/p>\n\n\n\n

Calling the detached part an \u201cengine\u201d is understandable, but technically inaccurate. Electric vehicles use drive motors rather than combustion engines, and the rear unit sends torque to the back axle through a compact electric drivetrain.<\/p>\n\n\n\n

BYD rejects a factory defect<\/h2>\n\n\n\n

BYD told reporters that the vehicle \u201cexperienced a severe underbody collision\u201d and that the separation was \u201ccaused by a collision while wading through water, not a quality issue.\u201d The company said operating data and damage at the mounting points indicated that an external force tore the rear drive unit free.<\/p>\n\n\n\n

That explanation is plausible, especially when floodwater can hide curbs, potholes, missing covers, rocks, and damaged pavement. Still, BYD has not released a written technical inspection, the vehicle\u2019s exact model year, detailed photographs of the failed mounts, or a repair report, so the public cannot independently test every part of its conclusion.<\/p>\n\n\n\n

How the Tang kept moving<\/h2>\n\n\n\n

One detail puzzled viewers. How could the SUV continue forward after losing such a major component?<\/p>\n\n\n\n

The Tang nameplate has been sold in battery-electric<\/a> and plug-in hybrid forms, while all-wheel-drive versions use a dedicated rear electric motor in addition to front propulsion. <\/p>\n\n\n\n

The current global Tang EV<\/a> also uses an all-wheel-drive powertrain, so continued movement could be possible if the front drive system remained functional, although the exact configuration of the damaged SUV has not been disclosed.<\/p>\n\n\n\n

The working lights offer another clue, but not proof of normal operation. A vehicle\u2019s low-voltage electrical system can continue powering lamps and electronics even when part of the high-voltage propulsion system has been damaged.<\/p>\n\n\n\n
