What's the difference between these two four-wheel drive systems? ?
As we all know, 90% of cars and urban SUVs are spent on well-paved roads in cities, and it does not need the powerful four-wheel drive performance that a car should have. In this case, Audi's quattro has completely become a decoration, which has not played much role and increased the self-weight of the car.
1.Toson four-wheel drive is simple and reliable, not smart enough.
Audi's old Toson four-wheel drive system is more like a manual gearbox, which can distribute the power of the front and rear axles in a ratio of 4/6, and daily driving is more like rear-wheel drive. It is simple and reliable with high transmission efficiency, but it can't play its heroic role well in most working conditions. Obviously, simple commuting, front-wheel drive or rear-wheel drive is more efficient in cities, so in this respect, Tosen four-wheel drive is too rigid and inflexible.
2. The electric four-wheel drive changes the power distribution of the front and rear axles in real time, which is efficient and fuel-efficient.
The brand-new electronically controlled four-wheel drive, thanks to the intelligent judgment and timely replacement of the computer, can quickly switch identities between four-wheel drive and front/rear drive. The most direct benefit of driving less than two rounds is that you can save 0.3L fuel per 100 kilometers. Think about the current oil price. Do you thank the engineer?
In fact, many people are not very concerned about the changes in Audi today?
Quattroultra timely four-wheel drive system was installed on the 20 16 new A4L, and no one paid more attention to it until the new Q5L went on the market. This shows that not many people care about four-wheel drive, let alone four-wheel drive. Half of them don't know that their BMW is rear-wheel drive. Can you believe it?
At this time, the owner of the four-wheel drive Audi Q3 stood up and said that his car had been changed. I'm sorry to be here. Q3 and Golf /A3 are the same platform. The four-wheel drive used above is Hande four-wheel drive, which may be due to the cost control of the platform. This four-wheel drive system can't realize the separation of the front and rear axles 100%, and at least about 5% of the power will be transmitted to the front and rear axles. In this case, the friction plate will overheat for a long time because it can't come out completely, and it can't bear more engine torque, so we can see that Audi's high-powered cars generally don't use this four-wheel drive system.
The core technology should be in your own hands?
Another reason why Audi uses timely four-wheel drive more in the new generation of products is the patent issue. Although TOSON differential is widely used in Audi, its technical patent is firmly grasped by Toyota from Japan, and the key technology is always out of breath. Audi, which has been advertising breakthrough technology, was naturally unhappy, so it buried itself in the four-wheel drive system and slowly began to line up its own models.
Sell cars first and then talk about four-wheel drive feelings?
Of course, in order to maintain their high-end image, Audi A8 and Q7 will continue to use TOSON four-wheel drive system, which is a trade-off strategy. Under the existing policies and rules, we must first reduce the comprehensive fuel consumption of the whole series of products, and then we can continue to sell cars when we meet the requirements and talk about our feelings.
