Fully Active Intelligent Chassis Debuts at 2026 Beijing Auto Show, Enabling "Dancing" Demonstrations in Multiple Models Over 5 Meters Long

At the 2026 Beijing Auto Show, vehicles exceeding five meters in length—including the NIO ET9, Li Auto L9 Liv-is, and BYD Yangwang U9—performed synchronized, music-driven "dancing" maneuvers inside the exhibition hall, drawing significant audience attention. The demonstration showcased the real-world application of fully active intelligent chassis technology. Traditional automotive suspensions are passive mechanical systems composed of springs, shock absorbers, and anti-roll bars, capable only of passively absorbing road impacts. Their adjustments suffer from latency, often resulting in issues like body roll during cornering. In contrast, the fully active intelligent chassis centers on “independently controllable four-wheel suspension,” integrating three core subsystems: perception, decision-making, and actuation. This system enables millisecond-level precise control over each wheel’s movement, allowing dynamic and free adjustment of the vehicle’s posture. The perception system continuously gathers real-time data such as road conditions; the decision-making system processes this information using high-performance computing chips and generates control commands; and the actuation system delivers powerful per-wheel lift capability to execute these commands rapidly. By eliminating mechanical anti-roll bars, the chassis achieves “four-wheel decoupling,” enabling complex combinations of movements. In terms of ride comfort, the technology can proactively anticipate road conditions and suppress vibration frequencies that commonly cause motion sickness. For handling and safety, it effectively mitigates body roll during cornering, adjusts vehicle posture in emergency scenarios, and supports variable ground clearance functionality. Moreover, as a critical hardware foundation for advanced autonomous driving, it provides essential actuation capabilities. However, the technology faces challenges including high costs, reliance on manufacturer-authorized service for repairs, expensive maintenance, and relatively high energy consumption—which may negatively impact vehicle range. Industry trends indicate that fully active intelligent chassis systems will evolve toward drive-by-wire architectures, software-defined functionality, and holistic domain integration. Drive-by-wire enhances response speed and control precision, aligning with autonomous driving requirements; software-defined features allow continuous performance optimization via OTA updates; and holistic integration with AI technologies promises broader applicability across vehicle models and usage scenarios. The technology is expected to gradually expand from premium segments into mainstream markets, driving transformative change across the automotive industry.
