First of all, explain the basic terms:

1, the scientific name of the heavy truck with nose you mentioned is the coach car.

2. The scientific name of a heavy truck without nose is a flathead.

A heavy truck with a nose will lower the center of gravity of the whole vehicle and be beneficial to the layout of the engine, which is really good. At the same time, because there is a nose protrusion in front, the whole car is "

However, the heavy truck with organic head will lead to the driver's poor line of sight in front, and the whole vehicle will be too long, which will affect the minimum turning radius. In addition, because the long-headed car effectively reduces the length of the whole car, more space can be arranged in the cab, such as luxury sleepers and so on.

In addition, due to the strong study habits of Chinese people (is it a cottage? ), adopted a merciless XX (omit the word 100 here, you know) strategy for flat-headed heavy trucks in Europe. Therefore, at present, flat-headed cars are everywhere in China, but no long flat-headed cars can be found.

However, due to the sharp rise in oil prices in recent years, the drag coefficient of long-headed vehicles on semi-trailer tractors is relatively small in expressway with good road conditions (there is basically no pit on expressway, so it is not important to save fuel even if the line of sight is good), so they began to recover.

For example, both faw liberation and Dongfeng Group have developed long-headed cars, and even China Heavy Duty Truck, the originator of China Steyr, wants to give it a try.

Therefore, for these two different cab products, it is necessary to make effective choices in combination with their working conditions.

Believe my answer, the landlord should be satisfied.
