The biggest impact on the high-power tractor market in 2016 was the formal implementation of the new GB1589 regulations. However, judging from the 2017 annual business car show of major mainstream car companies, the high-horsepower model is still on site, and instead of marginalizing large-scale horsepower tractors, each company has pushed it to an efficient market segment.
Nowadays, the most important thing for the rapid development of logistics and transportation is high efficiency, which is also the advantage of high-powered tractors. Also pulling the 49T cargo, the 500-horsepower tractor will save more than 20% of the transport time than the 400-horsepower tractor. At the same time, the engine of the 500-horsepower segment can achieve the best economical speed in high-speed transportation with greater reserve torque, and at the same time reduce fuel consumption efficiently. Therefore, the 2017 high-powered tractors will still have considerable advantages in the area of ​​efficient transportation segmentation.
FAW Liberated J6P500 Horsepower Tractor 
The reporter noticed on the scene of the FAW Liberation Annual Meeting that there was a 500-horsepower J6P tractor on display. This car is equipped with the new CA6DM 313-liter engine, the maximum torque of 2300N.m, it is said that this engine can output up to 550 horsepower. Compared to the 11-liter engine, the new CA6DM 313-litre engine has better low-speed torque output and better vehicle power output. At the same time, the machine adopts an overhead camshaft design, which can make the intake and exhaust control more accurate.
To match the new 13-liter engine, the car uses a model 12TAX230M gearbox, this gearbox uses 6X2 main and auxiliary boxes, double countershaft design, with 12 stalls, in addition to transmission gear oil maintenance cycle can reach 100,000 Kilometers.
In the drive axle, this J6P uses the most mature 457 rear axle. The rear axle also uses long oil change technology, which can achieve 100,000 kilometers of gear oil replacement, reducing the number of vehicle maintenance users and improving operational efficiency. In order to meet the high mileage requirements of modern logistics, as with the pilot version J6, the front and rear axles of the J6P are all lubricated with a Connair oil lubricated wheel end and can be up to 500,000 km long for maintenance.
Dongfeng set sail Moderators play a large torque 
The attractive models of Dongfeng Commercial Vehicles are not large horsepower, but they are mainly used for high torque. The biggest change before the Dongfeng Tianlong Qiqiu Edition T45L tractor was its change of power chain. The new model was equipped with a Dongfeng Cummins ISZ45041 engine with a displacement of 12.972L, capable of outputting 450 horsepower and a maximum torque of 2330N.m.
This 13-liter machine does not seem to have much power in terms of power performance of 450 horsepower, but the engine is more biased toward low-speed, high-torque output. It can reach a maximum torque of 2,300 Nm between 1000 and 1300 rpm and can reach 80% of the maximum torque only at 900 rpm. With such adjustments, the vehicle can have a relatively strong power output in the initial stage of starting, and it can also reduce the frequency of downshifts when climbing a hill.
In addition to the engine, other components of the power chain are upgraded accordingly. Dongfeng Tianlong set sail version uses the Fast 12JSD240TA gearbox, head speed ratio of 12.1, the highest gear is overdrive, the gearbox uses a large center distance design, higher reliability. The rear axle of the vehicle is matched with the mature Dongfeng Dana 485 drive axle, which has strong bearing capacity, convenient maintenance and replacement, and speed ratios of 3.64, 3.42 and 4.11 are optional.
China National Heavy Duty Truck HOWO-T7H540 horsepower tractor 
At CNHTC's 2017 business annual meeting, SINOCHEM exhibited HOWO T7H tractors equipped with Mantech's 540 hp engine. The car is equipped with China National Heavy Duty Truck MC13.54-50 engine, the output power of 540 horsepower, the maximum torque can reach 2500Nm, and meet the five countries / Europe emissions. In addition, this engine has a cold start and air intake electric heating function, this function is also very practical for the northern cold winter.
The Howard T7H tractor uses the AMT high-torque overdrive transmission and the 3.36 rear axle with a small speed ratio, which forms a gold power ratio with the engine. In addition, the vehicle is also equipped with a hydraulic retarder, even in the complex road conditions in Yunguichuan do not have to worry about the problem of frequent braking.
JAC Gehl K7540 Horsepower Tractor
In the direction of high-power heavy trucks, JAC Gehl developed K7 tractors. The vehicle's power chain uses the heavy-duty Manchester MC13-540 horsepower engine, which can produce 540 horsepower and a maximum torque of 2500 N•m. The engine is matched with a ZF 16-speed transmission and the Meritor small-speed rear axle. At the same time Gehlfa K7 is also equipped with airbag cab and seat, ZF hydraulic retarder, parking heating system and other configurations. 
It is worth mentioning that the Kelvin K7's golden power chain enables the vehicle to reach a speed of 95 km/h at 1200 rpm while driving at high speeds, ensuring sufficient power in high-speed logistics. In addition, the Gehl K7 cab adopts an advanced wind resistance design, and the actual wind resistance coefficient is only 0.532, which can effectively reduce fuel consumption.
Bei Ben heavy truck V3ET530 HP high efficiency version tractor
On the site of the Bei Ben Heavy Trucks Annual Meeting in 2017, Bei Ben exhibited a high-powered heavy truck, the V3ET high-efficiency tractor. Named V3ET high-efficiency version because the car uses a new power system, equipped with Weichai 13L State V engine, the maximum output of 530 horsepower, and the engine is matched with the ZF Chongqing 16-speed manual transmission and Beiben small Speed ​​ratio single bridge, can provide a good guarantee for efficient logistics. 
In terms of detail design, Bei Ben used aluminum alloy materials such as rims, fuel tanks, and gas storage tanks to achieve a lightweight vehicle. In terms of active safety and passive safety, BeiBei V3ET high-efficiency version uses WABCO brake control system, standard ABS+ASR, VOSS structural brake pipe system, optional EBS, exhaust brake and hydraulic force Speed ​​and so on.
Tiger hit Sichuan modern 480-horsepower tractor <br> <br> Sichuan modern business exhibited at the annual meeting of the Tiger record 480 horsepower tractor type and other models almost no difference, the only only be distinguished from the identification of the body 480. The car is powered by a 12.7-liter Powertec engine with a maximum output of 2350 Nm. The maximum output is 480 hp, and the emission meets the national five standard. Matched with it is the modern self-owned brand Moss 12-speed manual gearbox. 
The exhibition car uses the world's leading engine pump nozzle technology, the maximum horsepower up to 520Ps, so that Chuanghu has the fuel-efficient than all domestic same-class competing products, and the entire tiger system is equipped with WABCO gas push disc brakes and German horses The branded airbag can increase the braking efficiency and safety while the vehicle can also be adjusted to a height of 190mm, which is convenient for hanging and lifting and improves the passage of vehicles. It is suitable for transporting precision instruments.
At present, China's logistics and transportation industry is developing in a highly efficient and integrated manner. The number of individuals and retailers is getting smaller and smaller. Instead, it is the rise of logistics companies and logistics fleets with stable sources of supply. Compared with traditional retail transportation, the biggest advantage of logistics companies is that they have a stable source of supply, which effectively avoids the occurrence of phenomena such as unloading and waiting for cargo during the transportation process. The high-powered tractors have greatly improved the entire transportation process. Operational efficiency.
In addition, with the implementation of the GB1589 regulations, overloading has become more and more difficult, more users can't pull and can only choose to run, and the same load, high-power heavy truck transportation can be more efficient and more fuel-efficient, so for high-speed long-distance For logistics transport users, high-power heavy trucks will still be their preferred model. On the side, in 2017, the high-powered “fire†is likely to be rekindled by the “wind†of efficient transportation.
