Gasgoo Munich- IM Motors announced today that its flagship SUV, the LS9 Hyper, has achieved a trio of breakthroughs in chassis technology, as reported by Gasgoo on January 30. The model marks an industry first as the only mass-produced SUV equipped with a full four-wheel steer-by-wire system. It has also passed the reliability challenge set by the China Automotive Technology and Research Center (CATARC), becoming the first steer-by-wire production vehicle to earn this certification. Additionally, the new vehicle will feature SAIC Motor's first mass-produced tri-motor vector all-wheel-drive system.

As the lead drafter of the new national standard for steer-by-wire (GB17675-2025), SAIC Motor has conducted long-term research and development in this field. The IM LS9 Hyper stands as a concentrated showcase of these technical achievements; it fully complies with all requirements of the new standard, helping push steer-by-wire technology into the phase of large-scale mass production.

According to a test report from CATARC, the full steer-by-wire system on the IM LS9 Hyper demonstrated stability across multiple rigorous tests. Even when simulating a system failure at high speeds of 160 km/h, the vehicle maintained driving stability and controllability. The system also withstood extreme temperature swings exceeding 70 degrees Celsius without any degradation in steering performance. This reliability verification lays the groundwork for steer-by-wire chassis to serve as the core motion control platform for advanced intelligent driving, potentially accelerating the rollout of Level 3 and higher autonomous driving functions.
Furthermore, the new model's tri-motor vector all-wheel-drive system will work in tandem with the steer-by-wire system, delivering a further boost to the vehicle's dynamic handling capabilities.
The IM LS9 Hyper is set to officially launch soon, with further product details expected to be released by the company.
