"We didn't play well in the first half of 2006, but we grabbed it back in the second half. In 2007, it must have started in the first half. I wouldn't finish 115,000 cars in the whole year." Facing the 2007 market In battle, Cai Zhenfa, the general manager of FAW Trading Corporation, is confident.
In fact, looking back at the truck market in 2006, although the industry as a whole has rebounded in 2006 compared to the negative growth in 2005, most truck companies have not had a good day. The domestic heavy-duty truck market continues to undergo structural adjustments. High-tonnage, high-horsepower, and high-tech heavy-duty trucks have increasingly increased market demand, while domestic trucks tend to focus on medium and small tonnage products.
In particular, the long-term dominance of the liberation of China's truck market and most of the liberation of Dongfeng products was concentrated in 8-15 tons. Heavy trucks with large tonnage suddenly dropped, causing truck companies to lose market opportunities. The companies that produced more than 15 tons of products, such as China National Heavy Duty Truck Group and Shaanxi Heavy Duty Truck, grabbed a good advantage because of their product advantages.
Faced with the abrupt changes in the market situation, liberation not only further improved the product line, but also established a regional management mechanism, improved the network information platform, and accelerated the response to market demand. According to statistics, as of the end of November 2006, FAW has liberated 121,427 vehicles, and it is expected to achieve sales of 13,500 units in the year, an increase of 6% year-on-year, including Liberation Company's sales of 84,740 liberation of medium- and heavy-duty trucks, which is expected to exceed 90,000 vehicles throughout the year. , the year-on-year increase can reach 2.1%.
By the end of November 2006, the market share of liberation medium and heavy trucks has reached 19%, and it is expected that the market share of the whole year will reach 19.1%. Although the start failed, but the year-end inventory, liberation is still firmly on the championship.
The trend of China's truck product development is to develop towards "two poles" (ie light and heavy). According to foreign agency forecasts, by 2010, heavy trucks with more than 15 tons will account for 70% of the Chinese market. This point has formed consensus in the industry.
In order to adapt to changes in the market and demand, major truck companies have successively launched large-tonnage products. Dongfeng Commercial Vehicle Co., Ltd. has launched the Tianlong series, Dongfeng Liuzhou Automobile has launched Balong, and FAW has librated and launched Aowei.
Dong Chunbo, deputy general manager of FAW Group Co., Ltd., said: "In 2007, Liberation will launch the J6 high-end product platform. It is a world-class new commercial vehicle platform that is developed independently to meet China's national conditions.
