Intelligent steering research: Rear-wheel steering prices drop to RMB200,000-250,000
From January to October 2025, the number of vehicles equipped with rear-wheel steering reached 106,000, representing a year-on-year increase of 36.5%. IM alone held a 45.4% market share in rear-wheel steering.
The starting price for the rear-wheel steering configuration is as low as RMB219,900. The starting price for the 2025 IM L6 with rear-wheel steering (steering angle: +-9°) is RMB219,900. In addition, the starting price of the 2026 IM LS6 with rear-wheel steering is as low as RMB224,900, meaning that rear-wheel steering is no longer an exclusive feature of high-end models.
The main advantages of rear-wheel steering: 1. In low-speed scenarios, by deflecting in the opposite direction to the front wheels, the "virtual wheelbase" is shortened, reducing the turning radius. This is suitable for scenarios such as parking and U-turns on narrow roads, and is especially effective for long-wheelbase or large vehicles; 2. In high-speed scenarios, the rear wheels rotate in the same direction as the front wheels, increasing the "virtual wheelbase" and improving vehicle driving stability. In addition to the traditional advantages mentioned above, some brands combine rear-wheel steering with autonomous driving and rain/snow driving modes to improve driving performance.
Denza: "Toe-in" Driving Mode in Rain and Snow, 15° Crab-like Angle
The Denza N8L, equipped with rear-wheel steering and based on the e3 platform, offers an "toe-in" driving mode in rain and snow. This means that the two rear wheels can be turned inward, similar to skiing, where the feet are kept in an toe-in position to maintain body stability and achieve deceleration.
The Denza Z9GT, which also uses the e3 platform, has its front and rear wheels rotating in the same direction, allowing the vehicle to move diagonally and achieve a crab-like motion, which can increase the vehicle's flexibility in narrow spaces. Its rear wheel steering angle is 10°, but with the integrated dual-motor differential control, it can achieve a maximum crab angle of 15°.
Maextro: Rear-Wheel Steering with Pavement Pre-Emption and 16° Crab Angle
The Maextro S800, which uses the Huawei Touring Dragon Platform, features +-12° rear-wheel steering. The Touring Dragon Platform is deeply integrated with the fusion perception and prediction network based on HUAWEI ADS to achieve pavement pre-emption and chassis control. The rear wheel steering is combined with pavement pre-emption to enable cornering pre-emptive steering and improve cornering speed. In addition, the Maextro S800 features rear-wheel steering and differential torque control, enabling a 16° crab-like driving mode.
On December 2, 2025, the national certification standard GB17675-2025 "Basic Requirements for Automotive Steering Systems" was officially released. The new standard will completely replace the previous "GB17675-2021" standard from July 1, 2026. One of the most significant revisions to the new standard is the removal of mandatory requirements for mechanical connections to address emerging technologies such as steer-by-wire (SBW) and electric power steering (EPS).
In addition, this revision adds requirements for failure, alarm and functional safety of steer-by-wire systems, defines the safety boundaries of steer-by-wire, and revises the functional safety requirements for transmission steering systems and rear wheel steering, guiding the iterative development of steering technology in China. The standard was drafted by several OEMs, including domestic and joint venture brands such as NIO, Li Auto, XPeng, BYD, Geely, Xiaomi, Huawei, Toyota, and Mercedes-Benz.
Several OEMs have already planned to equip their vehicles with steer-by-wire products, and it is expected that steer-by-wire will be widely adopted in vehicles in 2026-2027.
To meet the demand for higher power and dynamic response, 48V steer-by-wire has entered the market. Currently, companies such as Bosch Huayu, Xiaomi Group, Tuopu Group, DECO Automotive, and Jingwei Hirain have launched or deployed 48V steer-by-wire systems.
Bosch Huayu: 48V Direct-Drive Steer-by-Wire
In December 2025, Bosch Huayu showcased its 48V direct-drive steer-by-wire at its technology day. A representative stated that "the 48V architecture reduces current and heat dissipation while meeting the demand for high power output." In scenarios requiring high power output, such as emergency avoidance and automated parking, the advantages of steering performance influenced by the 48V architecture will be more significant, and the driver can intuitively perceive the faster steering response brought about by the increase in engine speed. It is reported that Bosch Huayu's 48V steer-by-wire product is expected to enter mass production as early as 2027.
Tuopu Group: 48V Steer-by-Wire
In June 2025, Tuopu Group showcased its innovative 48V steer-by-wire system and 48V dual-pinion electric power steering system for the first time at the 2025 Guangdong-Hong Kong-Macao Greater Bay Area International Auto Show. The 48V steer-by-wire system includes a feel simulator and a front wheel steering actuator. Compared to traditional electric power steering systems, the steer-by-wire system removes the intermediate shaft connection structure and controls the steering feel simulator and front wheel steering actuator through redundant electrical signals, achieving precise, efficient and adjustable steering control. It has advantages such as easy installation, redundancy and reliability, and high efficiency.
