1. 후륜 스티어링 시스템의 탑재수는 전년 대비 36.5% 증가했습니다.

2025년 1월-10월, 후륜 스티어링 시스템을 탑재한 차량의 대수는 10만 6,000대에 달했고, 전년 동기 대비 36.5% 증가되었습니다. IM 단독으로 후륜 스티어링 시스템 시장 점유율의 45.4%를 차지했습니다.

후륜 스티어링 사양 차량의 시작 가격은 21만 9,900 위안입니다. 2025 IM L6(후륜 스티어링 기능 탑재 및 스티어링 각도 ±9°)의 스타트 가격은 21만 9,900 위안입니다. 게다가 2026 IM LS6의 후륜 스티어링 모델도 22만 4,900 위안화라는 저가격 설정이 되어 있어, 후륜 스티어링 기능이 더 이상 고급차 전용 장비가 없어진 것을 나타내고 있습니다.

2. 새로운 국가 스티어링 표준이 발표되었으며 기계식 스티어링 연결의 필수 요구 사항이 철폐되었습니다. 이로 인해 스티어 바이 와이어 표준이 설정되었습니다.

2025년 12월 2일, 국가 인증 규격 'Basic Requirements for Automotive Steering Systems'이 공식적으로 공표되었습니다. 신규격은 2026년 7월 1일부터 기존의 'GB17675-2021' 규격을 완전히 대체합니다. 새로운 등급에서 가장 중요한 개정점 중 하나는 스티어 바이 와이어(SBW) 및 전동 파워 스티어링(EPS)과 같은 새로운 기술을 수용하기 위해 기계적 연결의 필수 요구 사항을 제거했다는 것입니다.

게다가 이 개정은 스티어바이 와이어 시스템의 고장, 경보, 기능 안전에 관한 요건을 추가하고, 스티어 바이 와이어의 안전 경계를 정의하며, 변속기 스티어링 시스템과 후륜 스티어링의 기능 안전 요건을 개정하고, 중국에서의 스티어링 기술의 반복적 발달을 유도합니다. 이 표준은 NIO, Li Auto, XPeng, BYD, Geely, Xiaomi, Huawei, Toyota, Mercedes-Benz와 같은 국내 및 합작 브랜드의 여러 OEM에 의해 초안되었습니다.

이미 복수의 자동차 제조업체가 자사 차량에 대한 스티어 바이 와이어 제품의 탑재를 계획하고 있어, 2026-2027년에 스티어 바이 와이어가 차량에 널리 채용될 전망입니다.

3. 48V 스티어 바이 와이어가 주류로

고출력화 및 동적 응답성에 대한 요구를 충족시키기 위해 48V 스티어 바이 와이어가 시장에 등장했습니다. 현재 Bosch Huayu, Xiaomi Group, Tuopu Group, DECO Automotive, Jingwei Hirain과 같은 기업이 48V 스티어 바이 와이어 시스템을 발표하거나 탑재하고 있습니다.

이 보고서는 중국의 승용차용 지능형 스티어링 산업에 대한 조사 분석을 통해 산업 발전, 국내외 OEM 레이아웃, 공급망 등에 대한 정보를 제공합니다.

Intelligent steering research: Rear-wheel steering prices drop to RMB200,000-250,000

1. Rear-wheel steering installations increased by 36.5% year-on-year.

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.

2. New national steering standards have been released, removing the mandatory requirement for mechanical steering connections, thus providing a standard for steer-by-wire

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.

3. 48V Steer-by-Wire is popular

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.
