To systematically analyze the key points and impact of EU automotive regulations, evaluate the corresponding technical challenges, and support Chinese enterprises in formulating effective compliance strategies, this study introduces the regulatory frameworks of the United States, Japan, and the European Union, with a primary focus on the EU regulatory system and its whole-vehicle type approval framework. It examines the evolution and impact of EU regulations across 4 key areas: emissions, connected and automated driving, environmental protection, and safety. The findings indicate that the ongoing upgrades to EU regulations will profoundly reshape the industry landscape. Firstly, the Euro 7 emission standards will accelerate the transition of commercial vehicle power train technologies toward high-efficiency, clean, and zero-emission solutions. Secondly, the increasingly dense framework of regulations for connected and automated driving, coupled with infrastructure upgrades, is redefining the approval and validation models for intelligent vehicles. Finally, the continuously rising environmental requirements regarding battery carbon footprints, battery passports, and recycling are establishing green barriers that span the entire product life cycle. In response to these changes, Chinese enterprises must address technological gaps, strengthen industrial chains, enhance standardized management, and strategically plan ahead to build and maintain long-term advantages in international competition.
