Earlier this year, the Ministry of Environmental Protection and the Ministry of Industry and Information Technology jointly issued the "Announcement on the Implementation of Phase V Motor Vehicle Emission Standards" (hereinafter referred to as the "Announcement"). The "Announcement" pointed out: According to the process of upgrading oil products, the implementation of five standards for motor vehicle countries in certain regions. At the same time, the "Announcement" also formally clarified the timetable for the full implementation of China's five standards for motor vehicles. 
From April of this year, all the light gasoline vehicles, light diesel passenger cars, and heavy-duty diesel vehicles (transport, sanitation, and postal use only) imported, sold, and registered in 11 provinces and cities in the eastern part of China have strictly implemented the national five standards, according to the “Announcement "The announced schedule will be implemented on January 1 next year. All of the above models must fully implement the National Five Standard. In addition, since July 1st of next year, all heavy-duty diesel vehicles must also meet the requirements of the National Five standard.
The issuance of the "Announcement" means that the government departments have accelerated the pace of implementation of vehicle pollutant discharge standards, which is a top priority for commercial vehicle companies. Today, less than 20 days from January 1, 2017, means that the deadline for the full implementation of the National Five Standard for all heavy-duty diesel vehicles is approaching. At this critical node of emission upgrades, how are commercial vehicle companies getting ready?
Everything is ready for the Dongfeng Wind. “The SAIC Hongyan Jieshi Zhongjiao axle carrier, the brand new Jieshi equipped with the Fiat CURSOR11 engine, and the Hongyan 4×2 model have all met the national five emission standards and not only closely follow national policies and regulations. And meet the needs of the market at the first time.†Jiang Jianhua, deputy director of SAIC Iveco Hongyan Commercial Vehicle Co., Ltd.’s general manager’s office, said in an interview that SAIC Hongyan’s product upgrades were made immediately after the “Announcement†was issued. jobs. "At present, our five national products have good market performance in many provinces and cities across the country, and it is not a problem to meet the needs of large-scale procurement in the market." In October of this year, the Jieshi C500 equipped with a new series of five-nation engines was introduced. The M500 new car was officially put on the market and received a large number of orders from dealers across the country. 
"In order to actively respond to the implementation of the State Five emission regulations, since 2014, the CNHTC Sales Department has submitted applications for new vehicle models in three batches according to the urgency, based on feedback from key regions. Currently, CNHTC has a number of countries. Five product announcements, especially Mantech products, all met the national five emission standards.†Duan Hengyong, deputy general manager of China National Heavy Duty Truck Sales, said that as a leading company in domestic high-end heavy trucks, Sinotruk switched five products ahead of schedule, using Uman Technology as Support has been the first in China to promote more environmentally friendly products.
As the first-tier distributor of China National Heavy Duty Truck Group, Xu Banghu, the general manager of Shenzhen Optimus Automobile Trading Co., Ltd., also confirmed to reporters that a large number of CNHTC's five new products have entered the market. “The National Five Policy has been stimulating the nerves of users from this year. Month we have already started to reserve five new products for China National Heavy Duty Truck. At present, more than 80% of our customers choose the national five-standard vehicle when purchasing a car, Xu said.
At the Guangzhou Commercial Vehicle Show recently held, FAW Liberal also showed new products of the five national emission standards, including the 460 hp J6P6 x 4 pilot version tractor, two different wheelbase liberation J6L4 x 2 trucks and a Liberate four models of the J6P6×4 intelligent muck truck. It is understood that on the day of the implementation of the Five National Standards in the 11 provinces and cities in the east, five products of the FAW Liberation State held a national listing ceremony in Beijing. On that day, sales in the Beijing area reached more than 200 vehicles.
The price gap is not big
State five products have become the main user selected models <br> <br> For manufacturers, the National V emission standards increase the cost of production brought about by the implementation, technology upgrades, and stock car country, four of digestion, are forced to consider issues . According to analysis by industry insiders, after the full implementation of the National Five Standards for diesel vehicles in the next year, the country's three diesel vehicles will become yellow standard vehicles, and the national four diesel vehicles from 2019 to 2020 are likely to become yellow standard vehicles. For users, the normal service life of a truck is generally 6 to 8 years. If you still purchase a diesel engine of the National IV emission standard, it means that the vehicle may become a yellow-labeled vehicle within 3 to 4 years of use. 
In this regard, China National Heavy Duty Truck Chengdu Ace Commercial Vehicle Co., Ltd. Deputy General Manager Shi Jianli told reporters that fortunately now is still a period of time away from the full implementation of the five national standards, the new emission standards for the coming, the heavy truck is actively clearing the trump card Digestion stocks.
Shi Jianli believes that according to the promotion of the policy, the adoption of Guowu Products has become a trend. In the buffer period of the Fourth National Switching State Five, local distributors can negotiate with the manufacturers and hand over the State IV stock car to the manufacturers for disposal. Sales network to help dealers break down pressure.
The technical upgrading brought by the National Five Standards is even less of a problem. Jiang Jianhua analyzed that the products of many heavy-duty truck companies in China are currently being developed based on Euro VI standards in terms of emissions. Therefore, it is difficult for emission upgrades to be technically difficult. He believes that many companies in the development of the country's fourth product at the same time the State Fifth Technology reserve, and the four countries, five countries have a certain degree of inheritance of their own technology, most parts have a certain degree of versatility. "Furthermore, the price difference between the five countries and the four countries is only a few thousand dollars, which greatly reduces the economic burden of emission upgrades to users, and becomes a major factor in the purchase of five products by the country," Jiang Jianhua said.
Shi Jianli also stated that technically speaking, the four countries and five countries are basically the same, especially in terms of heavy trucks. The price difference between the two countries is not big, and the country is different from the state of the fourth country. Users can generally accept it.
To seize the high ground of the market situation closely follow the implementation of <br> <br> National V emission standards, not only that the national automotive industry to upgrade technology, attention to environmental protection, but also a test of the true strength of automobile manufacturers, including core technology and to The degree of reaction to market demand changes. 
At the Beijing auto show held this spring, Xin Mingji, general manager of Sichuan Hyundai Motor Co., Ltd. told reporters that after the implementation of the National Five Standard, the national standard vehicle will not be able to be on the market, meaning that it cannot be sold locally. It is important for companies to plan ahead for the country’s five product lines. Applying for an announcement earlier means occupying the market as early as one day. Xin Mingji believes that in order to occupy the commanding heights of the market, it is necessary to keep abreast of the environmental protection policy, and the model that meets the emission standards will be put on the market at the first time, and product certification and announcement applications will be filed at the first time.
“At present, we have completed the switch between the country’s four to the country’s five products.†Liu Zhigang, deputy general manager of commercial vehicle sales company of Dongfeng Liuzhou Automobile Co., Ltd., told reporters that before the implementation of the National Five Standard, Beijing Five was implemented in advance for commercial production companies. It is a good reminder that on this basis, Dongfeng Liuzhou has captured market information in a timely manner, made good technical reserves, and quickly completed the upgrade of product discharge standards. In addition, Futian Daimler brand communications lecturer Zhou Yang told reporters that from Beijing Five to Five, from smart interconnection to super trucks, Futian Daimler can follow the emission regulations to upgrade the general trend to meet the needs of users.
Faced with the market environment in the future, many responsible persons of heavy truck companies told reporters that the implementation of the National Five Standards has a great impact on commercial vehicle companies. There are many problems that need to be solved in the follow-up, including whether there are sufficient spare parts for China Five products and whether the maintenance technology is Mature and so on. In the next step, they will strive to gain market opportunities and seize the commanding heights in the downstream of the industrial chain in light of the deficiencies in the country's five new products. In the brand, channels, services and other aspects of full force.
