Chinese automaker Voyah has unveiled its in-house developed flagship intelligent chassis, the Huju P (Premium) solution, at the Dongfeng Group Technology Week and Voyah Huju Intelligent Chassis Technology Exchange Day on September 15, 2026. The system will debut on the new Voyah Dreamer 9 flagship MPV, which goes on sale September 22, according to Chinese outlet Electric Bond (电动邦).
Solving the large-MPV ride-and-handling dilemma
Voyah positions the Huju P as a direct answer to a persistent industry problem: how to make an extra-large MPV combine the smooth, quiet ride of an executive sedan with agile, precise handling. The company's chairman, Lu Fang, said the chassis was developed by polishing driving and riding qualities together, aiming to make comfort and control mutually compatible rather than a trade-off.
The Huju P builds on Voyah's existing Huju chassis family. The Huju A (Allroad) variant, used on the Voyah Taishan series, has undergone all-terrain crossings such as the Yinshan mountain route, while the Huju D (Dynamic) variant on the Voyah Zhuiguang S has been pushed through high-speed tunnel manoeuvres. The new Huju P is tailored specifically for flagship MPVs.
The chassis uses an aluminium-intensive architecture, with aerospace-grade aluminium alloys accounting for over 90 percent of core load-bearing components, cutting unsprung mass by about 30 percent. It pairs a triple-chamber independent air suspension with dual-valve electronically controlled dampers, a combination Voyah claims is unique in China. The triple-chamber design offers four levels of physical stiffness adjustment across a 65 percent range, aimed at countering rear-end sag under heavy loads. The dual-valve dampers separate compression and rebound control for precise damping, while a front double-wishbone and rear five-link suspension keeps wheel movement in check.
Steering, braking and powertrain hardware are also upgraded. The Huju P comes standard with rear-wheel steering capable of up to 10 degrees in both directions and a dual-motor redundant electric power steering system, cutting the turning diameter by one metre to a minimum radius of 5.9 metres. Braking uses a second-generation IPB 2.0 integrated brake assembly with a dual independent hydraulic circuit, plus front dual-piston calipers and large ventilated discs, achieving a 100-0 km/h stopping distance in the 36-metre range. The chassis is built on an 800V high-voltage platform with dual electric motors delivering a combined peak output of 560 kW (475 kW for the pure-electric version), with no power fade at 130 km/h and cabin noise below 62 dB at 120 km/h cruise.
Smart control and safety redundancy
Beyond hardware, Voyah's full-stack software algorithms give the Huju P predictive capability. A forward-looking camera system scans the road 100 times per second from up to 15 metres ahead, allowing the suspension to proactively smooth bumps rather than react to them. A centralised VMC (vehicle motion control) system coordinates suspension, braking, steering and drive systems in a domain controller, solving for the optimal vehicle attitude in real time. This enables a crab-walk mode for high-speed lane changes, and Voyah cites test results from the China Automotive Technology and Research Center showing a moose test speed above 80.5 km/h and stability after a single tyre blowout at 131 km/h on icy roads.
The second-generation IPB 2.0 braking system reduces nose-dive during stops by 35 percent, addressing a common complaint in battery-electric vehicles (BEVs). A dedicated "VIP mode" smooths acceleration and braking transients, and lowers the body by 40 mm when the vehicle comes to a stop for easier entry and exit.
The Huju P is described as the first flagship MPV chassis in China built on a full L3 autonomous driving architecture, with eight layers of system redundancy covering perception, computing, braking, steering, power supply, communication, interaction and positioning. In braking and steering, dual independent hydraulic circuits and dual-chip, dual-motor EPS provide seamless fallback if the primary system fails.
Voyah says the chassis underwent millions of virtual simulations and more than 20 extreme road-condition tests, and has accumulated nearly 500 chassis-related patents domestically and abroad. The Dreamer 9, which carries the Huju P as standard, is positioned as a new benchmark for China's high-end MPV segment.
