Voyah, the premium electric vehicle brand under Dongfeng, unveiled its self-developed Huju P (Premium) intelligent chassis on September 15 during Dongfeng's Technology Week and Voyah Huju Intelligent Chassis Technology Exchange Day. The new platform will debut on the Voyah Dreamer 9, a flagship MPV scheduled to go on sale on September 22, according to Chinese outlet D1EV.
Hardware highlights
The Huju P chassis is built on an aluminum-intensive architecture, with over 90 percent of core load-bearing components made from aviation-grade aluminum alloy, reducing unsprung mass by about 30 percent. It features triple-chamber independent air springs paired with dual-valve EDC electronically controlled dampers, a combination Voyah says is unique in China. The air springs offer up to 65 percent stiffness adjustment across four levels, addressing common issues like rear-end sag under heavy loads. The dampers use separate compression and rebound valves for precise two-way damping control.
Steering is handled by a standard-equipment bidirectional 10-degree rear-wheel steering system and a dual-motor fully redundant EPS setup. This reduces the turning diameter by one meter, giving the large MPV a minimum turning radius of just 5.9 meters. Braking uses a second-generation IPB 2.0 integrated brake assembly with dual independent hydraulic circuits, front dual-piston calipers, and large ventilated discs, achieving a 100-0 km/h stopping distance in the 36-meter range. The chassis also includes a dual-circuit RBU backup for safety redundancy.
Power comes from an 800-volt high-voltage architecture with dual electric motors delivering a combined peak output of 560 kW (about 751 hp), or 475 kW (about 637 hp) in the pure-electric configuration. Voyah claims the powertrain maintains full output at speeds up to 130 km/h and keeps cabin noise below 62 dB during 120 km/h cruising. The body structure uses 2,200 MPa ultra-high-strength steel in a cage design with laser-welded door rings.
Intelligent control and safety
The Huju P chassis incorporates Voyah's in-house developed VMC intelligent chassis control system, which coordinates suspension, braking, steering, and electric drive through a centralized domain controller. A forward-facing 15-meter high-resolution preview system scans the road 100 times per second, allowing the chassis to proactively smooth out bumps rather than react to them. The system also enables a crab-walk mode for high-speed lane changes and has achieved a moose test result exceeding 80.5 km/h and stability during a single tire blowout at 131 km/h on icy roads, according to tests by China Automotive Technology and Research Center.
The second-generation IPB 2.0 brake system reduces nose-dive by 35 percent, addressing motion sickness common in EVs. A dedicated "premium mode" smooths acceleration and braking transients, and the vehicle automatically lowers its body by 40 mm when stopped for easier entry and exit.
Voyah positions the Huju P as the first MPV chassis in China built on an L3 autonomous driving architecture, with eight layers of system redundancy covering perception, computing, braking, steering, power, communication, interaction, and positioning. The company says the chassis has accumulated nearly 500 patents and won a first-class award from the China Society of Automotive Engineers.
The Dreamer 9, which Voyah calls a new benchmark for large MPVs, will be the first model to adopt the Huju P chassis. Its launch on September 22 marks Voyah's push to redefine the premium MPV segment by combining executive-level comfort with agile handling, a balance the company says has been difficult to achieve in large vehicles.
