Chinese people like SUV that is known to do, but if you buy low with front-wheel drive under the premise of sufficient funds, it is certainly someone will question why you did not buy a four-wheel drive version. In their mind, they do not bad money, as long as the four-wheel drive, it’s time to buy a four-wheel drive version. But these people can not wait even four-wheel drive is valid, there are several types are confused, in the end can only give you give an example of Audi double diamond ……
If you still have the intellect, will know not only expensive to buy time four-wheel drive, the latter cost is also higher. If bought with front drive not see the difference, it would be embarrassing. So the question comes, we Chinese people really need a four-wheel it?
There is currently on the market can be divided into four-wheel drive four-wheel drive, four-wheel drive, four-wheel drive three timely. Each has its own different attributes and principles, so let’s briefly talk about some of the differences between these three kinds of systems.
timely four-wheel drive is the more common type, as the name suggests is to use four-wheel drive at the appropriate time, other times all-wheel drive . Many people also say that it is “false four-wheel drive”, but if you use them in certain conditions, it is not necessarily bad. Transverse current mainstream urban SUV platform are using the timely four-wheel drive system, such as RAV4, CX-5, CR-V, X-Trail and so on. Which, like the new RAV4 timely four-wheel drive as well as dual clutch rear axle to distribute torque around, off-road capability is good.
at any time is the four-wheel drive, all-wheel drive vehicle when the wheels are. It is connected by a flexible center differential, the front and rear shaft is connected to separate front and rear differential, torque is assigned to each tire. It is the best four-wheel drive system, the advantages of four wheel torque output has stabilized, there will be no delays, especially for wet roads, but also helpful for handling road. Wherein the symmetrical full-time undoubtedly more representative Subaru Audi quattro and the four-wheel drive.
But then, as now the worldRequirements for increasingly high fuel consumption, these traditional full-time four-wheel drive system does not have any advantage in terms of fuel consumption, so many manufacturers have begun to use timely turning into a four-wheel drive, so see quattro, xDrive is not necessarily full-time four the drive.
is a four-wheel drive means are different sub-wheel drive or two timing drive, four-wheel drive it is more timely compared dependence of the driver active control. By switching two center-drive or four-wheel drive mechanism, and after turning on the four-wheel drive is rigidly connected to the center, the structure is simple and reliable, more applications on hardcore off-road vehicles, pickups. Such as the Toyota FJ Cruiser, Jeep Wrangler, pickups and other Hella Fox.
However, there is a problem four-wheel drive, four-wheel drive mode, since the lower is the central rigid connection, it is equivalent to the center differential lock, can only be used on non-paved road, if the paved road use is likely to cause damage to the vehicle hardware.
there are a lot of people think that you have to buy four-wheel drive in the northeast extreme climates, not really. As far as I coordinate the Northeast a friend told me, basically every year starting from October, off the northeast began to snow. Due to the low temperatures, high forest cover, melting ice and snow of time will be stretched, but also piled up. This is to save half a year or even next year in March also see snow.
In addition, due to the northeast from south to north across the temperate and boreal, temperate monsoon climate in summer and a lot of rain, the highest annual precipitation in the region even You can reach more than 1000mm. However, his family did not have to buy four-wheel drive, but is taking another operation – to change tires. Because he knows, and then a powerful four-wheel drive and no snow tires useful.
on
tubing has been done a test, four-wheel drive version of the model and a precursor version equipped with winter tires fitted with summer tires compared in the snow test.
After the braking, climbing, acceleratingAfter elk and many other performance tests, pre-installed snow tires of a four-wheel drive just after blasting summer tires. Thereby also proved that, on snow and ice tire choice than the four-wheel drive is not more important. So this way, is not a four-wheel drive system, it is the absence of meaning? Not really, there are some places that need it.
If the road conditions are particularly poor urban vehicles, do not have a four-wheel drive, then there will be many difficulties in their daily commute. In addition, more leisure time and those people who like to buy a four-wheel drive car did nothing wrong. Correct! Alxa is like to go kind of person.
those who can only buy a car for daily commuting use, and this car usage scenarios are more than 90 percentage urban roads, bad roads and no friend in need, then you really do not need to buy a four-wheel type specifically for this purpose, because the precursor had enough! For example, in the north of Guangzhou-Shenzhen on living people, there is no need to buy a car four-wheel drive. Even if you occasionally want to feel the joy brought by four-wheel drive, Nazan can also rent ah, right?
It would appear that no matter how manufacturers to publicize its four-wheel drive SUV’s how powerful the system, it is nothing but a gimmick nothing more. Because you have to really want to buy X1 to the exclusion of sand, or buy a CR-V to climbing, these operations will make you look as if “lost wisdom.”
But if you live in a flat city road and off-road and there is no need to buy a four-wheel drive version is also stunned. I see you nothing more than a place to spend more money to not (nor donate my point). In that case, you can only when I did not say anything! Even buy Karma! Buy it now, buy it!
