Usually when watching some car review programs, I often hear 100 km acceleration, 100 km brake, what is the use of this 100 km acceleration and 100 km brake? Today, Brother Meow will talk to you. The acceleration of 100 kilometers is how much time it takes for the speed of the car to stop to 100 kilometers per hour, and the acceleration of 100 kilometers heard in previous years is basically about 10 seconds.
If it is less than 5 seconds, many of them are performance cars, sports cars, 4 seconds more than 3 seconds is a super run, that is to say, 100 kilometers of acceleration within 5 seconds, the era of fuel vehicles, basically, many belong to the sports car series exclusive. However, since BYD developed a 542 strategy a few years ago, the 100 km acceleration has been within 5 seconds, especially Tang DM, and the 100 km acceleration is more than 4 seconds.
A large SUV did more than 4 seconds, and suddenly the 100-kilometer acceleration went from the high position of the sports car to a civilian product. So what is the direct impact of this sports car-level acceleration experience on the actual car. The first point is that the feeling of pushing back is very strong, the better the acceleration of 100 kilometers, the faster the car starts, the throttle is light, and the car jumps out. Second, when overtaking, especially at low speeds or when avoidance starts, 100 km/h is still useful.
For example, although many trams are not so bullish when overtaking at high speed, when they overtake at low speed, especially in urban areas, they will feel the power shouting. In addition, if you wait in line on the side of the road, but see a large truck suddenly behind, the big truck is still flashing lights, honking, obviously can not brake, this time if the car 100 kilometers acceleration is particularly good, in the short term can quickly change lanes.
If the 100 km acceleration is very poor, even to more than ten seconds of grocery shopping car, the throttle is stepped on for half a day without moving, and when you just drove halfway, the car behind slammed into it, knocking the car into two halves, so the 100 km acceleration is also good for emergency avoidance. So is not the faster the 100 km acceleration is better, from the experience point of view, it is definitely the faster the better, but after the 100 km acceleration is too fast, if you are not used to it, especially if some are still back-drive, it is easy to have traffic accidents.
So why are there some friends at present, from the fuel car 100 km acceleration of 12 seconds of the car, directly after changing to the 100 km acceleration of 4 seconds of the car, at the beginning of the drive, always feel unsafe, easy to have accidents. From the perspective of the entire large traffic safety environment, I personally think that the 100 km acceleration is appropriate, for example, for ordinary family cars, I think 100 km acceleration, the tram to more than 5 seconds is already great, as for the fuel car, in fact, many of the 10 km acceleration of the grocery car are 10 seconds away, and you are not driving very well.
After watching the 100 km acceleration, and then look at the 100 km brake, the faster the acceleration of the car, the more fierce the run, then the corresponding brake should be the better, otherwise the acceleration is very strong, but the brake is not ok, this will not become a disaster. So the 100 km brake for the safety of the car, more important than the 100 km acceleration, because the 100 km brake is measured by distance, it is no longer with time, that is, the car from 100 km per hour to the full brake stop, how long is this distance, this distance is definitely the shorter the better, many cars are 35 meters, 36 meters or even not less than 40 meters away.
The shorter this distance, it means that the better the braking performance of the car, especially when encountering an emergency, such as driving on the high speed, there is a sudden traffic accident in front, if the 100 km brake performance is good, a foot brake collapses, just in front of the thirty meters, braked, there is a difference of 0.5 meters I collided with the big truck, but if the 100 km brake is 40 meters, this time you can't brake, there is a distance of 5 meters, it means that you directly hit the inside of the big truck.
Although the final kinetic energy is not so large, but at least the front windshield, bumper, airbags are all scrapped, and the airbags may knock out your teeth, if from a safety point of view, the 100 km brake is a more important parameter than 100 km acceleration, for our car, there is indeed a very practical safety help. Usually when buying a car, if you want to be cooler, you can also look at the acceleration of 100 kilometers.
But in my opinion, the vast majority of people buy this car, not as a sports car, will not go to the street, the vast majority of cases to buy a car is only for good service to life, so safety is the most important, these two items, 100 km brake is actually more important than 100 km acceleration of a parameter, so when we buy a car, in addition to paying attention to acceleration, it is recommended that you can pay more attention to the 100 km brake distance of this car, because for the vast majority of friends ordinary family cars, braking is actually more important than acceleration.
