Nexteer Automotive (HK 1316) announced its Electro-Mechanical Brake (EMB) system has completed development and validation and is now ready for mass production, making its market-ready debut at Auto China 2026. The supplier said the milestone gives it full Motion-by-Wire chassis coverage spanning Steer-by-Wire and Brake-by-Wire, with more than 20 customer evaluations completed and several programs advancing into technical co-development.
Highlights
- EMB has completed simulations, bench tests, and extreme winter validation one year after its Auto Shanghai 2025 debut
- More than 20 OEMs have evaluated the system; several projects are moving into technical co-development
- Nexteer now offers full-stack Motion-by-Wire solutions combining Steer-by-Wire and Brake-by-Wire actuation
- System is positioned as an actuation layer for L3 and higher levels of autonomous driving
From Debut to Mass-Production Readiness
Nexteer’s EMB program has progressed rapidly since the system was introduced at Auto Shanghai 2025. In the past year, the supplier said it has completed product design, production line development, and supply chain integration. The EMB has passed simulation, bench, and extreme winter testing, and more than 20 customers have conducted test drives. Several of those evaluations have moved into technical co-development, according to the company.
Nexteer’s prior EMB reveal was covered on The BRAKE Report’s earlier reporting on the system’s Auto Shanghai launch, which detailed the platform’s architecture and its role in the company’s Motion-by-Wire strategy.
Market Context: China Leads EMB Commercialization
The announcement lands during a period of rapid EMB commercialization in China. Chery recently claimed the first mass-produced EMB application in its Exeed EX7, and other Chinese OEMs have signaled similar timelines. Nexteer framed its market-ready announcement around a broader industry shift, arguing that OEMs are moving away from stacking individual features and toward integrated chassis solutions for common driving scenarios such as city commuting and tight-space parking.
Full-Stack Motion Control Architecture
The core of Nexteer’s pitch is a shared technology stack across steering and braking. The company outlined four elements of its approach:
- Chassis control software with open interfaces. Nexteer’s proprietary braking-steering fusion software is designed to enable cross-domain functional safety redundancy and serve as an actuation layer for L3 and higher autonomous driving. The software is built to integrate with OEM software-defined vehicle architectures.
- Hardware reuse across domains. Actuator modules — including motors, reduction mechanisms, and sensors — and motion controller electronics such as ASIL-D MCUs, pre-driver chips, and power management chips are platformed across the steering and braking product lines, which Nexteer says shortens development and reduces system cost.
- Manufacturing synergies. Assembly equipment is reusable across steering and braking programs, and the company is leveraging its global manufacturing footprint for EMB delivery.
- Supply chain overlap. Nexteer cited high supplier overlap between its steering and braking components, which it said supports centralized procurement and scale economies.
Executive Commentary
“The integration of Nexteer’s Steer-by-Wire and EMB isn’t just a simple ‘1+1’ — it’s a natural evolution rooted in the fundamentals of mechatronics, and a key enabler for achieving both safety and cost-effectiveness in high-level autonomous driving,” said Jun Li, Senior Vice President, Chief Strategy Officer and APAC Division President, Nexteer Automotive. “Choosing Nexteer means more than just picking up two components — it means getting a complete, proven, production-ready, and cost-effective chassis motion control solution.”
Nexteer is exhibiting EMB and related technologies at Booth W1B03, Hall W1, at the China International Exhibition Center (Shunyi) during Auto China 2026.
