CAAS introduces rear-wheel active steering technology to upper mass-market EVs in China
Press Release, 23 October 2025
China Automotive Systems, Inc. (CAAS) has unveiled an innovative rear-wheel active steering system, making advanced vehicle handling technology accessible to upper mass-market electric vehicles (EVs) in China. This development marks a significant step in enhancing driving dynamics and safety in the rapidly growing EV sector.
The newly introduced system, developed by CAAS’s subsidiary Jingzhou Henglong, utilizes a ball-screw-and-nut actuator mechanism controlled by a sophisticated unit that processes vehicle speed and steering-angle signals. At speeds below 60 km/h, the rear wheels turn in the opposite direction to the front wheels, effectively reducing the turning radius and facilitating easier maneuvering in tight urban spaces. Above 60 km/h, the rear wheels steer in the same direction as the front wheels, enhancing high-speed stability and cornering performance.
Equipped with two independent motors for precise control of the left and right rear wheels, the system offers tailored steering responses to varying driving conditions. Jingzhou Henglong has established a dedicated production line for this technology and has delivered several testing samples to original equipment manufacturers (OEMs). The system was showcased at the 2025 Shanghai Auto Show, highlighting its potential to elevate the driving experience in mass-market EVs.
By integrating this advanced steering technology into vehicles priced near RMB 200,000, CAAS aims to democratize high-performance driving features, previously reserved for luxury models, for a broader consumer base. This move underscores CAAS’s commitment to innovation and its role in shaping the future of the automotive industry in China.
