Footage circulating on Chinese social media appears to show a BYD Fang Cheng Bao Bao 8 (marketed as the Denza B8 outside China) moving on three wheels along a two-lane commercial street in Jinshan Town, Lianyungang. Its raised front-left wheel has a yellow-and-red metal wheel clamp attached. Parked vehicles, other traffic and pedestrians are visible nearby.

The scene recalls BYD’s May 2026 demonstration of DiSus-P Ultra hydraulic suspension, which allowed the SUV to raise an individual wheel while moving on the other three. The earlier demonstration took place at a proving ground, whereas the circulating clip appears to show the vehicle on a public street.

From proving ground to public-road footage

On May 15, 2026, we reported on three-wheel driving demonstrations. During proving-ground trials, BYD demonstrated DiSus-P Ultra on the Fang Cheng Bao Bao 8 Flash Charge Edition, raising one wheel while the SUV moved on the other three.

BYD launched the Flash Charge Edition in China on May 13, 2026, with a starting price of 419,800 yuan (approximately 61,600 USD). The variant featured DiSus-P Ultra hydraulic suspension.

How DiSus-P Ultra lifts a wheel

DiSus-P Ultra is BYD’s hydraulic body-control system. During the Bao 8 Flash Charge Edition’s launch, it reportedly offered individual-wheel lifting, wheel replacement without a conventional jack, and low-speed three-wheel driving.

Reported specifications include up to 200 mm of suspension adjustment travel, an individual-wheel lift height of up to 300 mm, and a maximum lifting capacity of 9 metric tons (approximately 88.3 kN). These are reported system specifications, not measurements taken from the circulating clip.

BYD specified a maximum speed of 15 km/h (9.3 mph) for three-wheel driving during its May demonstrations. The circulating clip does not provide a verified speed measurement.

Road traffic law and safety implications

The public-road setting raises safety concerns beyond what the suspension system can prove on a proving ground. The footage appears to show the Bao 8 moving on three wheels along a street with other traffic, storefronts and parked vehicles nearby.

Article 21 of China’s Road Traffic Safety Law addresses vehicle safety requirements and the operation of motor vehicles with safety hazards. The footage does not establish whether the configuration shown constitutes a specific violation or led to an official enforcement action or penalty.
