In the first half of 2010, the heavy truck industry sold 584,200 vehicles, an increase of 112.7% year-on-year, which was approximately 91.9% of the full year of 2009. Thanks to the industry's heightened prosperity, Weichai sold nearly 300,000 engines in the first half of the year, which is approximately 90% of the whole year of 2009. Among them, heavy-duty trucks use 220,000 engines, which is close to 2009 annual sales, faster than the industry average. Growth rate: In the first half of the year, Weichai's engine production was basically in short supply, and the monthly intention orders exceeded 60,000 units. However, at present, the company's full production capacity is about 50,000 units per month. The production capacity restriction has led the company to reduce the supply of engines for construction machinery. . Mainly for heavy trucks, our transmissions sold 490,000 units in the first half of the year, which was 92% of sales for the whole year in 2009; Shaanxi Heavy Duty Trucks sold 60,000 units of heavy trucks, of which 20,000 were tractor-trailers, an increase of 296% year-on-year.
The pedigree of the diesel engine has gradually become complete, and the engine for heavy trucks currently has a market share of 35-40%. In the future, the growth of the plate business depends on the high-end and heavy-duty truck products. The 5-7L engine that began to be launched on the market in December 2008 has hit the market for passenger cars, excavators, and medium- and heavy-duty trucks. It has been tested in the market for nearly two years and has completed matching with some models. Positive feedback from customers is expected to start sales in 2011. There will be a bigger breakthrough.
The acquired Yangchai focused on 2-4L diesel engine products. In 2009, Weichai and VM entered into an agreement for the introduction of small-bore engine technology. The VM engine company is a well-known small diesel engine developer and manufacturer in Europe. It is a light passenger and passenger vehicle for Mercedes-Benz and Ford. The diesel engine supplier of the car products, the future of small diesel products can not be discounted.
