Construction of the Global Environmental Quality Vehicle Testing and Evaluation System and Its Application in Automotive Technology Marketing

With China's automotive exports rising to the top globally, the diverse overseas market environments impose higher demands on vehicle adaptability. This paper proposes a "Global Environmental Quality Vehicle Testing and Evaluation System," constructing a multidimensional testing framework covering climate adaptability, road condition adaptability, and extreme disaster resilience, addressing the shortcomings of traditional environmental testing in scenario coverage and dynamic coupling validation. The study integrates digital twin technology and multi-objective optimization methods to establish dynamic operating condition models, with experimental validation confirming the system's effectiveness. Additionally, technology marketing strategies based on test results can significantly enhance brand competitiveness. This research provides theoretical and technical support for the globalization strategy of the automotive industry, offering both engineering practicality and academic innovation value.
