Since the birth of the market segment of city, it has been a mixed identity. On the one hand, people think that the city SUV has greatly met the diversified needs of users' car purchase. It can not only provide more storage space than the car, but also have good passing performance, and can provide users with a more aggressive visual effect in appearance. On the other hand, many people think that urban SUVs are almost different. In terms of trafficability and four-wheel drive ability, the traditional off-road vehicle is more professional and has better ability to get rid of difficulties than the urban SUV; in terms of power and fuel economy, the driving experience and vehicle cost of the same displacement SUV are almost higher than that of the car, even the car washing costs 10 yuan more. However, with the continuous development and growth of urban SUVs, they are now more refined into small, compact, medium-sized, medium-sized and large-scale, car running and other different sub models, and the concept of urban SUVs is gradually promoted to highway SUVs, and even the most valuable four-wheel SUVs of the same level are competing. It can be seen that the established impression of urban SUV in the past has also come to a time of re establishment of cognition. In order to meet the demand of the current automobile market, what kind of urban SUV is more in line with the value standard of the new era? Just as the word "female" cannot be defined simply by long hair, curve, gentleness and other labels, the modern society mentions the four-wheel drive of urban SUV, and can't use the four-wheel drive ability of SUV as the judging standard. In fact, from the very beginning, we should realize that the four-wheel drive of urban SUV, as the name implies, is only applicable to urban road conditions, and only when there is a little better four-wheel drive technology can we compare it with off-road vehicles. So comparing the four-wheel drive technology of urban SUV with that of professional off-road vehicle is a black-and-white act. As for how much time can the four-wheel drive system be used in urban road conditions, anyone who has experienced it will say "real fragrance". In the daily use environment, it is not common to get rid of difficulties. In particular, automobile manufacturers like to do cross axle capacity test, single wheel test and so on, which are rarely encountered in urban vehicle environment. On the contrary, in rainy and snowy weather, southern cities need to cope with the road inundation caused by heavy rain, and northern cities need to cope with the wheel slip in snowy days. These are the times when the four-wheel drive ability of urban SUVs can be used. For example, when there are many roads and mountain roads in the third and fourth tier cities, potholes and rainy and snowy weather also test the four-wheel drive ability of urban SUVs. Similarly, it does not need too strong body rigidity or the ability to get out of trouble, just to maintain the stability and driving ability of the body, so as not to waste the user's trust in the four-wheel drive city SUV. Nowadays, the city SUV generally adopts the timely four-wheel drive technology, and the system will automatically switch the two-wheel drive and four-wheel drive modes according to the driving conditions of the vehicle, and most of the four-wheel drive systems can support the front and rear 100:0-50:50 torque distribution ratio, and the higher level can automatically adjust the front / rear and left / right independent torque distribution ratio. In this way, the "chicken ribs" that many people think are solved, because in the use process of drivers, the four-wheel drive system of urban SUVs can be switched freely, the two-wheel drive mode is used to improve the fuel economy of vehicles when driving normally, and when necessary, the four-wheel drive is started to assist driving to provide abundant power. In addition, the same displacement of the two-wheel drive version and the four-wheel drive version also have obvious differences in driving level. Especially in the process of rapid acceleration and high-speed driving, the former can only meet the power demand through cooperation and cooperation in the face of power demand, which often gives people a feeling of "power flesh" due to limited conditions. The latter can easily solve the problem of power demand with the help of the four-wheel drive system, which makes the user feel that the small displacement can be driven out of the large displacement under special circumstances. So if you have the same problem of choosing two or four-wheel drive when buying a car, don't hesitate, four-wheel drive is really different. In the period of relying on hybrid models to survive, many prospective car owners are eager to restore sales of fuel models. There is only one reason to ask: there is no four-wheel drive option for hybrid models. It was not until the mid-term modification of 2019 CR-V that the four-wheel drive system was added to the hybrid model, coupled with the resumption of sales of the fuel version model, the monthly sales of CR-V after its return to the market easily exceeded 20000 until now. Including the brand-new RAV4 and willanda, which were just launched at the end of last year and last month, both of them, as brothers of the same family, not only take the hybrid system as the main driving force of the high configuration model, but also add the electronic four-wheel drive and the brand-new dynamic torque vector control system to the four-wheel drive system. Thus it can be seen that the four-wheel drive system of urban SUV has already got rid of the established impression of "chicken ribs" in the past, but has become one of the necessary skills to compete technology and value in the same level of vehicle models. In the current market joint venture mainstream city SUVs, in addition to the four-wheel drive system, high-value and low price has become one of the means of competition. For example, Ruiji, RAV4 launched at the end of last year and willanda just launched last month, all of the three models have a four-wheel drive guide price of more than 200000 yuan, and the four-wheel drive models are very rich in configuration. Among them, Ford Ruiji adopts the separable intelligent four-wheel drive system, in combination with the fourth generation EcoBoost engine + 8at gearbox, which can achieve the millisecond level accurate four-wheel torque distribution, quickly respond to the chassis system road condition feedback, and take into account the vehicle's fuel economy while stabilizing the body. RAV4 and willanda are even more powerful. The two kinds of power can provide three kinds of four-wheel drive systems, namely, the newly upgraded dynamic torque control system, which can realize the torque distribution ratio between 100:0 and 50:50 of front and rear wheels; the dynamic torque vector control system can realize the torque distribution ratio between 50:50 of front and rear wheels, and between 100:0 and 0:100 of left and right rear wheels continuously, so as to realize the high difficulty action of single wheel escaping; and With powerful electronic four-wheel drive and hybrid drive system, it can accurately distribute power in the process of starting, driving, slipping and deceleration, and can switch between two or four-wheel drive freely. In addition, CR-V fuel version and hybrid version are also available as four-wheel drive models. Haoying is temporarily absent from the provision of hybrid four-wheel drive. In addition, mainstream models such as Mazda cx-5, cx-4 and Qijun are equipped with timely four-wheel drive system, which is also one of the options not to be missed. All in all, four-wheel drive urban SUVs have already got rid of the established impression of the past, not only the hybrid system has been added, but also the price has once again broken through the traditional pricing standard of urban SUVs, becoming the first choice of more competitive and high-value vehicles in the new era. If you still think that the four-wheel drive of urban SUV is dispensable at this time, then you should try it yourself, and you will know what "Zhenxiang" is.
