Technical Breakthrough | WAY-ASSAUTO CDC Shock Absorber Enters the High-End Bus Market in Partnership with Yutong

Project Background

As the bus industry continues to move toward intelligence and premiumization, Continuous Damping Control (CDC) shock absorbers have become a core component for ride comfort. CDC technology sets extremely high requirements for dynamic damping response, system integration, and reliability control — a high-end market segment in commercial vehicle damping and a flagship project for Nanyang WAY-ASSAUTO's expansion into the high-end commercial vehicle market.

As China's leading bus manufacturer, Yutong Bus maintains stringent requirements for suppliers' R&D capabilities, concurrent development efficiency, and full-process quality control. Winning the Yutong CDC project was both a market opportunity and a comprehensive test of the company's damping R&D strength.

Business Engagement: Opening a High-End Cooperation

In 2025, leveraging the group's resources, the project team targeted the high-end damping segment and conducted in-depth business engagement with Yutong on the CDC project. Fully aligned with the customer's strategic direction and product positioning, the company stood out in intense competition and won the Yutong CDC shock absorber project, formally launching joint development.

Joint R&D: Overcoming CDC Technical Challenges

After winning the bid, the project's chief responsible person took the lead in conducting intensive technical alignment. Focusing on Yutong's CDC system integration logic, performance specifications, and in-vehicle validation conditions, the team refined requirements repeatedly and precisely identified technical challenges and potential risks.

This project is characterized by a tight schedule, high technical thresholds, and a long cross-functional coordination chain. Facing immense pressure, the project team stepped up proactively, coordinating and mobilizing resources across engineering, process, production, and quality to focus on overcoming the core technical challenge of damping characteristic matching. From solution iteration and structural design to prototype trial production and bench testing, the entire sample development process was strictly controlled. Every test data point was closely monitored, product performance was continuously optimized, and CDC prototype development and internal validation were completed on schedule.

In-Vehicle Validation: Customer Recognition and Small-Batch Supply

Following internal validation, the samples entered Yutong's in-vehicle testing phase. After repeated testing and calibration under real operating conditions, the WAY-ASSAUTO CDC shock absorbers met all vehicle design requirements and passed Yutong's installation test, earning high recognition for product quality.

The successful test completed the full chain from scheme design and prototype development to in-vehicle validation, laying a solid technical and trust foundation for small-batch installation and scaled supply cooperation.

Cooperation Value

The Yutong CDC project is a major milestone in the company's entry into high-end commercial vehicle damping. Its success fully validated the company's concurrent development capability in CDC technology and filled the gap in practical development experience for high-end intelligent damping products.

Through deep collaboration with Yutong, the company gained first-hand insight into the real needs of high-end buses for intelligent damper systems, accumulating end-to-end engineering experience in CDC development — from requirement analysis and technical problem-solving to vehicle integration — creating a replicable blueprint for future high-end damper projects with leading automakers. It also deepened partnerships with China's leading bus manufacturers, opening new opportunities for continued expansion in the high-end commercial vehicle market.

Conclusion

Deep expertise in damper technology drives vehicle upgrades. Riding the wave of smart commercial vehicle development, Nanyang WAY-ASSAUTO will continue to focus on high-end damper R&D, anchored in customer vehicle requirements, refining product performance, and strengthening cross-functional collaboration. We will partner with more industry leaders to support the high-quality development of China's commercial vehicle industry.
