Sunita SomvanshiA video of an SUV appearing to drive on three wheels has circulated online. Could a car with this system do it? Reports describe a low-speed emergency mode, not normal driving. Here is what the reported engineering involves.
The vehicle is the BYD Fangchengbao Bao 8, a luxury off-road SUV. The footage was shot in Jinshan Town, Lianyungang, and shows a wheel clamp on the raised front-left wheel. The system involved is DiSus-P Ultra, a hydraulic suspension.
Do not copy this on the road. BYD’s three-wheel driving is limited to 15 km/h for low-speed emergencies.
BYD has described the system’s uses as jack-free tyre changes and crossing obstacles. Reports say the system can lift a wheel up to 300 mm, with lifting force over 19,000 lb (about 9 tonnes). BYD demonstrated the technology at a proving ground in May 2026.
How does the BYD Bao 8 drive on three wheels? The DiSus-P Ultra system lifts the clamped wheel, and the vehicle can move at low speed in an emergency.
The actual speed of the clip is unknown. BYD’s stated uses are tyre changes and obstacle crossing, and the reported low-speed limit is 15 km/h. Do not test it on the road.
