Group 1 - The core viewpoint indicates that the passenger car intelligence index for July 2025 is 34.2, with specific sub-indices for intelligent cockpit at 36.5, intelligent driving at 38.4, and external intelligence at 16.5 [1] - The intelligent driving index of 38.4 has decreased by 1.3 units month-on-month, showing a slight decline from the previous growth trend [1]

Core Viewpoint - The article discusses the recent trends in the Chinese passenger car market's intelligence index, highlighting a slight decline in the overall intelligence index and its components, while emphasizing the long-term growth potential of the market driven by technological advancements and consumer acceptance [2][10]. Summary by Sections Intelligent Vehicle Index - The passenger car intelligence index for April 2025 is reported at 31.9, with sub-indices for intelligent cockpit at 34.4, intelligent driving at 34.5, and external intelligence at 17.0 [2][6][10]. Recent Trends - The intelligent vehicle index has shown a slight decline in April 2025, breaking a continuous upward trend observed earlier in the year. This decline is attributed to the market's response to the government's vehicle replacement policy, which initially stimulated growth but led to a significant drop in sales in April [10]. Sales Performance - In April 2025, the retail sales of passenger cars reached 1.755 million units, marking a year-on-year increase of 14.5% but a month-on-month decrease of 9.4%. The new energy vehicle (NEV) segment saw retail sales of 905,000 units, reflecting a year-on-year growth of 33.9% but a month-on-month decline of 8.7% [10]. Impact of Key Players - The decline in the intelligent vehicle index was notably influenced by a significant drop in sales of two main models from Tesla, which affected the overall market performance despite the NEV segment's relatively better performance [10]. Future Outlook - Despite the April decline, the article anticipates a rebound in the intelligence index in May 2025, driven by the launch of new NEV models around the Shanghai Auto Show. The long-term outlook remains positive, with expectations of substantial growth potential in the intelligent vehicle market as technology evolves and consumer acceptance increases [10]. Index Composition and Calculation - The intelligent vehicle index is composed of one primary index and three secondary indices, reflecting the market performance of vehicles meeting specific intelligent criteria. The calculation method involves the market share of vehicles meeting any of the criteria for the secondary indices [12][13]. Weighting Factors - The weighting factors for the indices are set at 47.5% for intelligent cockpit, 37.5% for intelligent driving, and 15.0% for external intelligence, reflecting their respective impacts on the industry [15][16][17].
