The van was first imported from Japan to China as a tool car, and the shape of this car is very similar to bread, and the pronunciation of "Minibus" becomes a van when it is read. This kind of car displacement is small and fuel-efficient, pulling people and carrying goods, and soon became popular in first- and second-tier cities, and later with the increase of national income level, vans began to develop to rural areas and suburbs, and to this day, it is still a means of transport that can be seen everywhere.
Many people think that the power of 1.5T household SUV is still not enough, and many vans have a displacement of only 1.2L, like the Shenche Wuling Hongguang is only 1.5L, but we often see that this kind of car can still run fast in the city even if it is overloaded, or full of goods, what is the black technology? Let's take the representative model of the van, The Light of Wuling, as an example, to talk about the secret of the "small displacement and large strength" of the van.
Transmission tuning + willing to step on the throttle
Most of the Chinese people driving family cars are reluctant to step on the accelerator, especially at traffic light intersections, most of the green light starts at turtle speed, either to save fuel or to cherish the vehicle. But van drivers are different, what they have to do is to deliver goods or passengers on time, dora fast running means that they can make more money, so they are often more willing to step on the accelerator. The van driver can pull the speed to three or four thousand revolutions in the afternoon with one foot of throttle, is the owner of the family car willing to step on it? Such a high speed of natural power is more abundant.
In addition to being willing to step on the accelerator, the gearbox tuning of the van is also different from the general family car, the vast majority of the manual gearboxes that buy the van first, the transmission efficiency is higher and more fuel-efficient, and when there is a lack of power, it can also be compensated by manual shifting. In addition, the low-speed gear radius of the van is often adjusted to a larger size, so that the low-speed torque is stronger, that is, the low-speed is more powerful, and the uphill also feels that the power is enough, but this tuning speed can not be accelerated as soon as it comes up. Like the 1.2L Wuling Light Zero Hundred acceleration to 18 seconds, which is the basic bottom of the family car.
Engine tuning
The van looks very energetic, but the data will not deceive people, like the 1.2L engine of Wuling Light, the maximum power is only 60kw, the maximum torque is 115 Nm, and even if the data is mediocre 1.5T home SUV, the power and horsepower are basically twice as much, but why does it feel that there is no van with strength? It is also related to the tuning of the engine.
The engine tuning of the family car should comprehensively consider fuel consumption, medium and high speed acceleration, low speed torque, and control NVH, but the van is different, as long as the low-speed torque is rushed to the end, after all, the van is pulling people and goods, and there is no need to consider noise. Therefore, the speed of the van is generally relatively high, like the speed of 80km per hour, and the speed can soar to 3000 rpm.
The van is much lighter
A family SUV weighs, about 1.4 tons, and what about a van? Generally around a ton. The reason is that the van structure is simple, the front cabin is short, the steel plate is thin, the engine is light, and there is no need to consider safety, so as to reduce the weight of the people and goods as much as possible in order to dora people. If you think about it, 400kg lighter than a family SUV, it's the equivalent of a car full of adults and a car empty.
For a lighter van, in fact, its thrust-to-weight ratio is not low.
Vans are mostly rear-drive
The strength of the van is also related to the drive form of the rear drive. In general, the front and rear drive are not much different in acceleration and climbing, but for a large number of vans carrying goods, the weight is pressed on the rear wheel, and the rear drive can allow the vehicle to obtain greater traction when climbing and accelerating, ensuring the stability of power output.
Most of the household SUVs are front-drive, a few are four-wheel drive, for the family SUV, the original body is heavier, coupled with the form of front-drive, the owner is not willing to big foot throttle, the extreme situation of the climbing ability is really possible to be inferior to the van.
The above points are the main reason why the van is fully loaded or even overloaded, and the main reason why the 1.5T home SUV power is not enough, in fact, in the final analysis, it is because the positioning and use of the two are different, a high-speed, small displacement van is exposed, but the god car Wuling Hongguang is not included, after all, it is a god car. This model of van is very practical, and it is believed that it will continue to shine in the north and south of the motherland.
