When everyone turned their attention to the overall warming of the heavy truck market, a battle of the express delivery industry was filled with smoke.
Recently, there have been several eye-catching events in the domestic express delivery industry. First, on the basis of maintaining a rapid growth of 50% for a long period of time, the express delivery industry has continued to make rapid progress this year. According to the latest data released, from January to July of this year, the total volume of business of express delivery service companies in the country reached 15.75 billion, an increase of 55.9% year-on-year; and business revenue has accumulated 202.6 billion yuan, an increase of 42.9% year-on-year.
Second, various transport equipment providers have accelerated the pace of product launches, including Dongfeng, which has launched new express delivery vehicles. Some companies even have to take the "big cakes" that import heavy trucks.
The rapid development of express logistics industry, the competition around this subdivided area is also constantly heating up. With the intensification of offensive and defensive warfare between domestic brands and imported brands, how will this market go? 
Express transport market competition upgrade
This year's heavy truck market is really exciting. According to the latest production and sales news from China Automobile Industry Association, from January to August, the domestic heavy truck industry sold a total of 439,400 vehicles, an increase of 19.7% year-on-year; and the semi-trailer tractor segment sold 212,621 vehicles, a 33% increase year-on-year.
Among these, the growth of express delivery vehicles has contributed a lot. Due to the rapid increase in end-user demand, trucks used for express delivery, short-distance distribution and urban distribution, as well as 9.6-meter long-haul trucks and 4×2 tractors for long-haul transportation, have rapidly expanded market capacity in recent years. In particular, the 4×2 express tractor has formed a competitive pattern in which imported brands occupy more than 1,000 kilometers of long-haul transportation and domestic brands compete for short- and medium-haul transportation below 1,000 kilometers.
“Express delivery trucks have developed very rapidly over the past few years, but the market has also changed dramatically. Originally, imported trucks took the lead in the 4×2 tractor market, but with the development of domestic tractors with 380-400 hp or more, 1000 Below the km courier transport market has gradually been captured by Dongfeng Tianlong and other domestic self-owned brands.†A person in charge of a heavy truck company told reporters that in the courier truck market, domestic cars are the absolute main force.
Xiao Bian learned that at present in the long-distance two-way express delivery market over 1,000 kilometers, Volvo, Mercedes-Benz, Scania and other European imports of tractors rely on 100 kilometers 26L fuel consumption (even lower), high horsepower, high reliability, high attendance The rate and other advantages are favored among the express delivery companies such as Sitongyida and Shunfeng as well as the dedicated logistics companies that undertake the express delivery business.
However, with the "Rising" of domestic cars, things are changing. At the 5th Express Club Meeting held in late August, Dongfeng Commercial Vehicle Co., Ltd., in conjunction with Dongfeng Cummins, exhibited Dongfeng Tianlong's flagship 4x2 high-end tractors. Such a product can impact the long-distance express transportation market occupied by imported cars? 
World War II made cars imported cars engine is backed by <br> <br> Dongfeng commercial vehicle, according to the relevant person in charge, this is high-end Denon's flagship 4 × 2 tractor since the Beijing auto show this year, for the first time in the "folk" publicly unveiled. Its main battlefield is the long-distance express logistics market dominated by imported vehicles.
In order to cope with more difficult competition, Dongfeng Commercial Vehicle has carefully built and "carved" this new car, and applied a large number of advanced configurations on it, including a full-balloon rear suspension, Volvo 14-speed transmission and double aluminum. Alloy tank (450+500L), full disc brakes, EBS electronically controlled braking system, Alcoa aluminum alloy wheels, cab full airbag suspension system, etc. "It uses the Tianlong flagship D760 high-ceilinged cab, which is much more spacious and comfortable than the flat cabs of many European truck brands that now have a large amount of express purchases. Moreover, its price is also very competitive, and it is the cheapest on the market. The number of imported tractors is much lower,†said Dongfeng commercial vehicle technicians.
At the same time, Tianlong’s flagship 4×2 express tractor featured another major feature, which is the Dongfeng Cummins ISZ13 heavy-duty heavy-duty engine. In fact, on the domestic long-term express delivery market, the reason why imported brands are well-received is, on the one hand, benefiting from the high reliability and low failure rate of their product platforms; on the other hand, it is also due to the low fuel consumption and high cost of their imported engines. No major repair miles.
"A lot of express delivery companies are setting fuel consumption at a time when the imported vehicles are generally around 26 kilometers per 100 kilometers, which is a few liters less than domestic cars. In terms of overhaul mileage, imported cars can basically achieve a million kilometers without major repairs. The rate is very high.†The person in charge of the Dongfeng Commercial Vehicle Market Department told the first commercial vehicle network.
In order to compete with imported brands and even later come to the top, Dongfeng Commercial Vehicle has high hopes for the ISZ13 engine. According to reports, this displacement of 13L of heavy-duty power covers 425-560 horsepower, and there are currently two 450- and 480-horsepower power-pack models.
As a joint development of Dongfeng and Cummins technology, ISZ13 engine can pick up the banner to help the vehicle to achieve "import substitution"? 
Who can laugh at the end of the offensive and defensive war "ISZ13 this diesel engine in terms of power output, reliability, attendance or from the fuel consumption point of view, in the domestic large displacement engine market are in a leading position, compared with imported machines are not much It uses the Cummins XPI ultra-high pressure fuel injection system, the maximum injection pressure of 2400bar, the maximum torque of 2500Nm, the characteristics of low speed and high torque is very prominent.†Dongfeng Cummins technical staff said. At the same time, the ISZ13 has passed more than 9 million kilometers of road mileage verification, and key components have undergone over 10 million fatigue tests; the B10's life span has reached 1.6 million kilometers.
"In addition, we have included the Cummins C-LINK vehicle networking system on the flagship of the Tianlong flagship. The system has various functions such as environmental information data display, vehicle fuel consumption management, cost management, driving behavior analysis, fault alarm, scheduled maintenance and other functions. For the express company's intelligent fleet management has a great help." The technician added.
It is understood that with the advancement of China's truck technology, the long-distance Express Express market is considered to be one of the few "highlands" remaining in the imported heavy-duty truck brand, following the attack by the domestic brands on the mixer chassis market. For this reason, Dongfeng and other companies have invested heavily in the past two years. They hope to compete with the imported heavy trucks to capture their market share and sales volume through competitive forms of battlefield battles, high-quality key parts and higher overall cost performance. 
Today, Dongfeng Commercial Vehicles and Dongfeng Cummins have joined forces to reinforce the competitiveness of domestic cars on this market segment. This high-end heavy truck market offensive and defensive battle, who can laugh at the end?
