The data shows that in September 2017, the narrow passenger car market accumulated 2.29 million vehicles, an increase of 4.6% year-on-year, and the growth was sluggish; the cumulative increase from January to September was 3.9% year-on-year. In the peak season of gold, silver and silver, September sales maintained growth, but the intensity of recovery was not strong. There should be no doubt that the follow-up months will continue to grow, but the growth rate will remain blurred. From the perspective of market segments, the sedan market continued to grow in September 2017, with a year-on-year decline of 1.1%; the cumulative decline in the MPV market expanded to -16.6%; the cumulative SUV market grew by 16.5%. The recovery of the car market is not strong; the growth rate of the SUV market is declining, and it is worthy of attention; the MPV market continues to fall into a quagmire. In the January-September period, the Volkswagen Department of the top ten of the sedans slid most of the time, with Ying Lang rising rapidly; the top ten decliners in the MPV market dominated, with the exception of the GL8 and Aileron; the top ten SUVs remained the same. The top ten growth rate of the sedan market will be different, and the pattern may change; the MPV market is deeply in the dark; the SUV market is a car company that saves lives. In terms of sales volume, SAIC-Volkswagen, FAW-Volkswagen, and SAIC General Motors have a solid leading position and relatively stable pattern. In the second echelon, another one-million-car sales car company has increased the number of million-year-old automakers in Geely. The top ten car companies are growing at the most, but the market downturn is testing the internal strength of the car companies. According to the ratio of sales by country to group, the sales volume of Chinese brands from January to September accounted for 40.8%, up 1.2% year-on-year, the Japanese ratio increased by 2%, the European system increased slightly by 0.5%, and the Korean and American lines declined. . The growth in the Japanese market was due to product adjustments and new product launches; the European system was derived from the overweight SUV market. Overall, the performance of the market in September 2017 was fair, and the recovery of the car market was not strong. Although the SUV market continued to grow, the growth rate declined; the downturn of the MPV market was difficult to change and continued to deteriorate. With the arrival of gold nine silver and ten quarters, the market ushered in growth, but the strength was not strong.
