Chinese automakers are advancing electric and hybrid vehicle technology at a blistering pace, showcasing innovations that are increasingly difficult for Western manufacturers to match. In a striking display of engineering prowess, BYD, Huawei-backed AITO, and Li Auto have demonstrated sophisticated active suspension systems that enable vehicles to drive, recover, and operate on just three wheels.
The latest highlight comes from BYD’s premium brand Denza with the B8 (also known as Fang Cheng Bao Bao 8) Flash Charge Edition. Equipped with the advanced DiSus-P Ultra (also referred to as YunNian-P Ultra) fully active hydraulic suspension, the luxury PHEV SUV was shown driving up a steep ramp while one wheel was completely lifted off the ground.
This isn’t just a party trick. The system introduces three core practical functions:
- Three-Wheel Driving Mode: In emergencies, such as a flat tire or damaged wheel, the vehicle can continue moving at speeds of up to 15 km/h on three wheels while maintaining stability.
- Wheel-Lift Tire Replacement: The suspension independently raises one corner of the vehicle, eliminating the need for a jack to change a tire.
- Off-Road Recovery: With up to 9 tons of lifting force per wheel, the system can help extract the vehicle from deep mud, sand, or ditches by lifting and repositioning individual wheels.
BYD is not alone. Similar capabilities have been showcased by:
- Li Auto on its L9 model with the Livis fully active hydraulic suspension.
- Huawei-backed AITO M9, which uses intelligent chassis technology for comparable one-wheel lift and three-wheel driving demonstrations.
These systems rely on highly responsive hydraulic actuators, road preview sensors, and millisecond-level electronic control that allow independent management of each wheel’s height, stiffness, and damping — far beyond traditional air suspension setups.
Just a few years ago, brands like Volvo, BMW, and Audi were considered leaders in chassis innovation and vehicle dynamics. Today, Chinese companies are not only catching up but setting new benchmarks through fierce domestic competition. Rapid iteration, vertical integration (especially in batteries, motors, and software), and a willingness to push unconventional features have accelerated this shift.These technologies offer real-world benefits:
- Enhanced safety in accident scenarios.
- Greater convenience for everyday owners.
- Superior off-road and all-terrain performance.
- Improved ride comfort combined with extreme capability.
China’s EV ecosystem is evolving beyond longer ranges and faster charging into intelligent chassis and software-defined vehicles. Features that once seemed futuristic are becoming standard in mid-to-high-end models, often at prices that challenge global competitors.
While questions remain about long-term durability, regulatory acceptance in Western markets, and real-world reliability under varied conditions, the momentum is undeniable. Chinese brands are turning high-tech demonstrations into production-ready advantages.
As the global auto industry grapples with electrification challenges, China’s aggressive innovation in areas like active suspension is forcing everyone else to raise their game. The gap, for now, appears to be widening.
