Chinese automaker Voyah has released a video showing its Dreamer 9 MPV driving while carrying a vertical stack of six vehicles, a stunt the company claims is a world first for a passenger car. The feat, dubbed the "Dreamer 9 moving tower," took place on September 20 and involved a tower nearly 11 meters high and weighing 18 tonnes, according to Chinese outlet 电动邦 (Dian Dong Bang).
The bottom vehicle in the stack performed starting, acceleration, and braking maneuvers, moving the entire tower. Voyah said this demonstrates a shift from static load-bearing to dynamic driving, turning the 18-tonne tower into a "moving safety fortress."
Engineering behind the stunt
Voyah attributes the achievement to its in-house developed technologies and vehicle engineering. The body uses a laser-welded door ring and a cage structure made with 2200MPa ultra-high-strength steel. The chassis, based on Voyah's proprietary "Tiger Crouch" platform for MPVs, features an all-aluminum construction that balances low unsprung mass with high structural rigidity. A three-chamber air suspension and dual-valve electronically controlled damping provide millisecond-level response, helping to suppress pitch under the 18-tonne load.
The vehicle's control systems include Voyah-Ai 4WD intelligent torque vectoring and an IPB2.0 brake-by-wire system, which manage power distribution and slip to maintain stability under extreme conditions. Power comes from an 800V high-voltage platform paired with dual electric motors, delivering sufficient torque for starting and accelerating with the heavy load.
Voyah framed the demonstration as proof of Chinese brands' independent capabilities in body structure and chassis load-bearing technology, calling it a milestone in moving from following international safety standards to leading them. The company reiterated its philosophy that "safety is the ultimate luxury."
The Dreamer 9 is Voyah's flagship MPV, launched earlier this year. It competes in China's premium MPV segment against models like the Denza D9 and Zeekr 009. The stunt is part of Voyah's marketing push to highlight the vehicle's safety credentials, though it also underscores the engineering challenges of balancing weight, rigidity, and dynamic performance in large electric vehicles.
While the video is primarily a promotional exercise, it offers a glimpse into the structural innovations that Chinese automakers are deploying to differentiate their products in a crowded market. Voyah, a subsidiary of Dongfeng Motor, has been expanding its lineup with both BEV (battery-electric) and EREV (range-extender) variants of the Dreamer, targeting families and business users alike.
