Car drifting

Let me systematically talk about my experience in practicing drifting for more than a year and the essentials I know. First, let me talk about why we need to drift. Drifting was not just invented because it looks good. The "drifting" phenomenon when a vehicle loses control can only be called sideslip. As I often say, POWER IS NOTHING WITHOUT CONTROL. The same goes for drift. Only if you can control this technical action as you wish, then you can be called drifting. If not, it can only be said that you are practicing drifting. As for me, I am currently just practicing drifting. So why drift? That is a way for another car to go through corners faster. Of course, drifting is also a stunt. It is undeniable that drifting is indeed visually and sensoryly attractive. There is also a saying that only four tires biting the ground, relying on alignment, and cutting APEX are the fastest cornering methods. Drift cornering is slower than this alignment method. In fact, not necessarily. First of all, look at what kind of ground it is. If it is an asphalt road, the speed is very fast. Generally, the wiring position is better, because it is the safest. The faster the speed, the harder it is to control the drift. In fact, as long as the tires are cornering at high speed, they will drift to some extent, and you may not even notice it. This involves a critical state of friction between the tire and the ground. What is the critical state? After experimentation. The tire maintains rolling friction with the ground, that is, the friction is greatest when it is basically not idling. When the tires start to spin and turn into sliding friction, the friction drops by 20%. Therefore, when the tire is about to slip but does not slip, this is when the friction reaches its maximum limit, and ABS was invented based on this. Therefore, when you feel that your tires are still biting the ground, it means that you have not maximized the friction of the tires. When the car drifts, of course it has exceeded the maximum friction, so the speed is faster than when it bites the ground. If you can control the drifting route well and use drift to get out of the line, it is certainly faster than simply biting the ground. quick. This also involves an issue of angular velocity and linear velocity, which is too deep to be mentioned here. However, real experts can ensure that the critical state of the tires is used to route the cables. That is really the fastest. We ordinary people should not ask so much.

Let’s talk about what kind of cars can practice drifting. Cars with a high center of gravity are not suitable, such as off-road vehicles and SUVs. It is best not to try such cars, even if they are rear-wheel drive, as they are easy to roll over. Cars with particularly soft shock absorption will not work if they are not modified. It is also easy to turn over, and particularly difficult to control. There are also very expensive cars, so I don’t recommend them. It hurts when hit. After talking about cars, it’s time to talk about the ground. What kind of ground is more suitable? I think dirt roads are the best, followed by water roads. Sand and gravel are not so good. First of all, there are no sand roads in Beijing, so forget about stones, unless you don’t want the tires anymore. It's okay if you choose a relatively smooth asphalt road, but you need to be braver and more skilled, because asphalt roads require relatively high speeds. It also causes the greatest wear and tear on tires. Snow roads are quite special. In fact, I think snow roads are the most fun and difficult. Because if you want to float, snowy roads are the easiest. Finally, let’s talk about which car is more suitable for practicing drifting. The first choice is of course rear-wheel drive. If you own a high-performance rear-wheel drive car and are interested in drifting, then I congratulate you, this is the best choice. You don't need to consider inertial drift. You only need to practice POWERSLIP to be powerful enough. The method N is simple, enter the corner, downshift, and accelerate hard at the front of the corner to produce OVERSTEER (oversteer) and then control the direction. Definitely chic enough. If you have a four-wheel drive car like WRX or EVO, then the drifting method is basically the same as that of front-wheel drive. Just refer to front-wheel drive. In fact, some four-wheel drive systems are very similar to rear-wheel drive and are biased towards rear-wheel drive. You can It performs basically the same actions as rear-wheel drive, so I won’t go into details here. The previous ones are all nonsense, so let’s talk about front-wheel drive now.

Drifting with the front-wheel drive is impossible without sufficient speed, so it is more difficult. Let's start with the method of pulling the handbrake. I will directly quote the post I wrote last time -

The handbrake is particularly difficult to control. When you first pull it, you feel that the rear wheel barely slides, but in an instant, it suddenly swings up with great force. Therefore, if you want to use the handbrake, you must adjust the handbrake to light. The rear wheel is locked with a slight pull, and the buckle must be removed so that it cannot slide sideways. As a result, the handbrake cannot be released in a hurry. If you cooperate well, you can drift at a large angle > I rarely use the handbrake now, and I am very careful when using it, mainly because the handbrake is not only a clumsy method, but also takes up one hand, leaving only one Hands on the steering wheel. It was very dangerous. I hit the steps outside the bend that time because I only had one hand holding the steering wheel. As a result, the left front shock absorber was damaged, the left front, left and rear tires were broken, and a trash can from the district sanitation sanitation truck was thrown away. The front bumper was also sacrificed. Let’s move on to another method, the weight transfer method. It can also be called weight transfer, which is the pre-bend braking and in-bend braking methods I mentioned before. When you enter a corner at high speed, the weight of the car is almost evenly distributed on the four wheels, so when you enter the corner, apply the brakes hard. At this time, due to the inertia of the car body, part of the load is transferred to the two front wheels. The load on the rear wheels is quite small at this time, and the friction is naturally small. If you jerk the direction at this time, the rear of the car will swing up. In fact, the principle of retracting the throttle before turning in the bend is the same as these two, which is to increase the load on the front wheel and reduce the load on the rear wheel. Then I will talk about inertial drift, and here is a direct quote from what I wrote before-- Here is another thing to add, the reason for starting to hit right is also related to the weight, the purpose is to give the right front wheel Increase the load, and then rely on inertia to allow the body to rotate based on the right front wheel. Generally, inertial drift on asphalt roads is scary. I asked my friends who have watched me drift, and they said it was scary anyway. The car body suddenly twisted around, and all four wheels slid sideways while smoking. Finally, let me tell you about drifting in the snow. Snow is arguably the most interesting place to practice drifting, because even a front-wheel drive vehicle can easily achieve the same feeling as a rear-wheel drive vehicle. And it’s most fun to use the stupid method before which is to pull the handbrake. When entering a corner, the moment you turn, or you pull the handbrake right after turning, the rear end slides sideways, and release the handbrake to control the direction. The key is to make the car go through the corner smoothly. When turning back, the speed should be stable and not too fast. After trying it a few times, I believe that a dedicated friend can get it right. The feeling of making a 90-degree bend with the front of the car pointed directly at the center of the bend, and you have to look at the side window to control the direction is absolutely great:) But I have also paid the price. , the speed was too fast, it slid sideways outside the bend, hit the steps, and finally caused the rear axle to deform, and had to spend money to replace it with a new one.

(Selected Reading) Finally, I will tell you about the most advanced drift method. These are things I have never tried in my life. Method 1: Scandinavian flick (Thanks to ‘Dabaodi Krachi’ DX for reminding me of the full name). All participating cars do not have ABS. A single step of the brake can lock the wheel. When an athlete rushes into a corner at high speed on a dirt road, which is not an asphalt road anyway, he or she will judge the route of the corner based on experience, and then lock the wheel at once. At this time, the locked front wheel is basically There is no guiding force, so no matter how you hit it, it will not change the direction of the car. Then it starts to turn, for example to the right. When it reaches a certain level, it basically slides to the place where you want to turn. You quickly release the brake. At this time, the front tire suddenly regains its guiding force and quickly pulls the body to the right. The car body rotates to the right at high speed, causing drift, which is complicated to say. It's not complicated to do. But you have to master the timing and the speed before and after. It's really not a simple matter. I have only tried it on snow, because the car has ABS and cannot be locked, so only on snow it is similar to without ABS >.

Method 2: Continuous drift method. In fact, I think it should be called S-bend drift method. The principle is basically the same as before, but it is actually an extension of the above method. Friends who are familiar with the game will know how to go through the S-turn.

It is to cut two consecutive APEX curves and try to go in a straight line, which is the fastest. However, if it is a dirt road, a snowy road, and the curve is large, it will definitely cause drift. What should I do? This method is to solve this problem. If you think that after completing the first drift, you then go in the opposite direction and do another drift, you are wrong. There are two points you have not considered. First, S turns are generally tight and there is no time to wait for the car body to slow down. Second, if you simply turn in the direction and wait for the car to turn around, you have no way to decide when the car will turn around. At this time, you miss the entry point of the second drift. Well, this method is to deal with this problem. Suppose there is an S-turn on a dirt road. First turn right, then turn left. Enter the turn at high speed. First, let the car drift to the right. If the turn is very narrow, you need to use the inertial drift route. First turn to the left, and then suddenly Turn to the right. At this time, the car begins to enter the first right turn. When it drifts to a certain position, the car body is already a little oversteering. Then keep the accelerator (key) and turn the front wheel sharply to the left. Don't think At this time, the car will immediately turn left, absolutely not. When you maintain a high accelerator, the front wheel driving force is too large, and the steering force after slipping is also very small. Just like the above, the car body will only rotate very slowly at this time. is the weirdest time because the car is drifting to the right but the wheels are facing left and the body is barely changing direction. Haha, you have drifted to the second corner and need to turn left. When you reach the second corner, quickly reduce the throttle (key). At this time, the front wheel that has already set the direction and is facing left quickly Obtain the guiding force and quickly rotate the body to the left. Start the second drift, thus successfully completing the continuous drift through the S-turn. The whole action is completed by two drifts or even inertial drift. It's amazing, hehe, let's find a game and try it. In life, I think we can just forget it.

I’ve talked a lot and I’m so tired. I hope everyone will also pay attention to safety, think more, and start learning together while studying. Use your brain more, don't just do it stupidly.

One more thing, regarding the HEEL AND TOE toe-heel movement, if you want to corner smoothly, it is impossible if you don’t know this movement. I won’t explain it to those who know it, but I will say a few words to those who don’t. That is, you have to change gears before entering a corner, and shift to the bottom gear. However, the speed of the gears in the gearbox will not match when entering the low gear at high speed. If the car is stuck, the car will be dragged and the clutch plate will be destroyed. You need to coax the accelerator to increase the gear speed at the other end. But before entering the corner, you have to slow down, so your right foot is too busy, so you need this action, step on the brake with your toes, use your heel to coax the accelerator, reach the position in one go, shift into gear, and enter the corner. I use TOE AND TOE to control the brake and accelerator simultaneously with the left and right sides of the forefoot. Decide based on your pedaling position and habits. In fact, there is a left-foot braking technique for front-wheel drive cornering, which is too deep, so I won’t go into details about drift here.
