Takeaways
- The EX7‘s EMB system achieves 90ms response time and 33m braking distance, with triple redundancy safety architecture fully homologated under China’s GB21670-2025 standard.
- No European Tier 1 supplier has achieved passenger vehicle EMB mass production; industry projections place large‑scale production after 2028.
According to Chery, the Exeed EX7 will launch in China on 17 April 2026. The company describes the vehicle as the world‘s first mass‑produced passenger car equipped with a pure electronic mechanical braking (EMB) system.
Traditional hydraulic braking uses fluid and pipelines to transmit pressure from the master cylinder to each wheel. EMB replaces all of that with electrical signals sent directly to actuators at each wheel, eliminating hydraulic fluid, master cylinders, and vacuum boosters.
EMB Technical Specifications and Supplier
The EX7’s EMB system was developed jointly with Suzhou Zuo Biao Xi Intelligent Technology Co. (Coordinates), a Chinese Tier 0.5 supplier. Chery executive vice president Li Xueyong stated the system required three years of development focused on millisecond response times, precise actuation, and extreme reliability. According to Chinese regulatory filings, the system achieves a 90 millisecond response time and 33 metre braking distance.
It uses a triple redundancy safety architecture with dual power supplies, dual controllers, and dual communication links. The system is fully homologated under China‘s GB21670-2025 national standard, with Coordinates receiving the first EMB mandatory certification certificate (No. 0001) in October 2025.
European Tier 1 EMB Development Status
Bosch, Continental, and ZF have each been developing EMB systems for over a decade. According to industry analyst reports, EMB mass production from European Tier 1 suppliers is not expected before 2027 at the earliest, with some projections placing large‑scale production after 2028.
In March 2026, ZF announced plans to establish an EMB production line in Wuhan, China, for calipers, a core brake‑by‑wire component. The UN R13 braking regulation is currently being amended to include provisions for EMB type approval, a process led by CLEPA, the European automotive suppliers‘ association.
European Market Outlook
The EX7 has no announced European launch. EU type‑approval for EMB would require compliance with amended UN R13 provisions still under review. One reading of this is that a Chinese OEM has crossed a safety‑critical engineering threshold before European Tier 1 suppliers.
The open question is whether Bosch, Continental, and ZF will bring passenger vehicle EMB to market before the next generation of Chinese premium EVs reaches European type‑approval pathways.
