In April 2004, the country began to implement the GB1589 "Vehicle Dimensions, Axial Loads and Quality Limits" vehicle safety standards to control the "large tonnage" and overloaded transportation in the truck market. Since 2005, China's heavy-duty truck market has experienced negative growth for the first time in eight years, and it has fallen by more than 33% year-on-year. According to the statistics of China Association of Automobile Manufacturers, in the first quarter of this year, China’s heavy trucks achieved a total of 74,435 units and 65,963 units of production and sales, which were down 20.38% and 9.1% respectively year-on-year, and the market continued to slump.
At the same time, heavy-duty heavy-duty trucks have risen against the market and have shown a strong upward trend. In 2005, the domestic heavy truck market sold more than 15 tons of heavy trucks with 60,000 vehicles, which was more than doubled from two years ago. From January to April this year, this trend became even more pronounced, and the demand for the heavy truck market above 280 horsepower rose rapidly.
Industry insiders predict that with the continuous upgrading of production technology and the continuous maturation of market consumption, the domestic heavy truck market will become more and more obvious with large tonnage and high-grade competition. Demand will become more and more prosperous. By 2010, the market demand will reach 150,000. Vehicles are the most lucrative cake in the heavy truck market and are bound to arouse competition among major auto companies.
In response to this new competitive situation in the heavy truck market, major domestic auto companies have all launched their own high-end products. In addition to Dongfeng’s “Dragon†launch, SAIC Huizhong launched the “Fleet Fleetâ€, Jinan Heavy Duty Truck launched “Hooverâ€, and Shaanxi Heavy Duty Truck also launched “Dragonâ€... which has consistently occupied the top spot in the domestic heavy-duty truck market of over 15 tons. China National Heavy Duty Trucks did not dare to slacken their efforts. By cooperating with Volvo, the world's second-largest heavy-duty truck company, it produced a series of heavy-duty trucks equipped with D12 high-powered engines. The addition of latecomers, especially those large automobile companies such as Dongfeng, SAIC, and FAW, which have rapidly increased in cross-border cooperation, technology, and overall strength in recent years, are rushing to catch up with the pattern of the domestic heavy truck market and the market is facing new challenges. A shuffle.
