China’s auto market roared back to life in September, the country’s traditional “Golden September” sales season, as buyers and dealers rushed to make the most of trade-in incentives before several local governments hit pause on their subsidy programs.
Data from the China Passenger Car Association (CPCA) showed that domestic car sales jumped 6.6% year-on-year to reach 2.27 million units, improving on August’s 4.9% growth. Electric and hybrid models continued to lead the charge, making up 57.2% of total sales — a milestone month where new energy vehicles (NEVs) finally outpaced traditional fuel-powered cars. NEV sales surged 15.5% from a year earlier, compared to a 7.5% rise in August, underscoring the country’s accelerating shift toward electrification.
As the autumn buying season kicked in, dealerships filled their lots to meet renewed demand, with inventories climbing to 3.04 million units by the end of September, up from 2.6 million a month earlier. But the surge also came with pressure. CPCA Secretary-General Cui Dongshu called for stronger financial support for dealerships struggling with thin margins, as automakers continue to push unsold cars onto the market amid cautious consumer sentiment.
Trade-in incentives had been a key driver of sales growth in the first half of the year, but funding shortages are now forcing some regions to pull back. Jiangsu province and Guangxi were among the first to suspend their local programs, followed by cities like Wenzhou and Hangzhou — a sign that the boost from subsidies may be fading.
BYD, China’s dominant player, logged its first monthly sales dip since February 2024, trimming output and watching its domestic market share slip to 14%, down from 18% a year earlier. Meanwhile, rivals Geely, Leapmotor, Xpeng, and Xiaomi seized the spotlight with record-breaking results, signaling a more competitive landscape among local automakers.
Tesla, which shipped 19,287 China-made vehicles overseas in September, wasn’t immune to the slowdown — its domestic sales fell 0.9%, extending a three-month decline. Still, China’s car exports overall remained strong, rising 20.7% year-on-year, slightly faster than in August.
“Golden September” brought a welcome boost for China’s auto industry, but also fresh signs of change. As government support tapers off and competition heats up, the next few months will test how well automakers can sustain momentum in the world’s largest and fastest-evolving car market.
