How to improve manual gear driving technology
This is a very simple and very meaningful thing. Because the working condition of an engine is reflected directly from the speed. Take the 4G63 engine on the Mitsubishi Lancer Development 7th generation (MITSUBISHILANCE REVO. VII) as an example, its maximum output horsepower is 280ps/6500rpm, and the maximum torque is 39kgm/3500rpm. In other words, it can output the maximum torque at 3500 rpm, and it has to wait until 6500 rpm for it to have the maximum horsepower output. Here is a common sense: Torque can make the car faster, and horsepower can make the car faster. In this sense, if you want to maximize the performance of your car, or if you want to enjoy a car with someone else, you must bravely turn the output belt with the maximum torque before stepping on it. The maximum horsepower output band, even if it is firmly waiting until the tachometer pointer hits the red line area of ​​the tachometer, will step on the clutch and increase it by one step. Then the above process will be repeated again.
There was once a bluebird (BLUEBIRD) U13 owner complained to him that his car was too slow. Someone was currently carrying him to a high turn around. It was a super car all the way, but he did not want the SR1E engine to turn upside down. The melody caused the owners to panic and became scared on the way, asking for mercy again and again. The original owner’s driving habits on weekdays were to shift gears in less than 2,000 rpm. If the engine had not yet had time to go out, it would have been pushed down by the speed he had raised. How could it run fast? In daily driving, you don’t have to Pull out all the speed, just find a speed point that you think is right (at present, the domestic car is generally the most suitable 3500rpm). This will not only exercise your engine's muscles, but also increase the driving pleasure. Why not do it? Perhaps someone often tells you to change the gear to look at the speedometer, what immediately after starting the second gear, 20 km on the third gear, 40 It is totally unreasonable that there are no scientific reasons. The gear ratio of Hyundai Motors is different. It is ridiculous to manage all models with such a naive model. If you believe in this theory, you can't play sports cars and cars in your life.

(B) heel downshift action HEEL & TOE
First understand the relationship between speed and shift, you will understand the subtleties of this action. Heel-to-toe action is a trick for driving racing. Before a semi-automatic gearbox comes out, anyone who wants to be a racer must first learn to follow the toe. In countries with deeper car culture such as Europe and Japan, the popularity of Heel toe movement is no less than that of the domestic "watch speedometer shift." At present, the heel toe movement is the most important chapter in the domestic racing training courses.
What is heel?
The operation method of the heel toe action is not difficult: first, depress the brake pedal with the right toe to decelerate. When the speed falls quickly below the maximum torque output speed (or below the shift point you believe), quickly press the clutch with your left foot. Pedal, right foot toes while maintaining the brakes, with the right foot heel pedal to the accelerator pedal and step down, immediately after the completion of the charge action to reduce the first gear, then the right heel left the throttle, left foot to release the clutch pedal, right toe to brake Until you can step on the accelerator, release the brakes and press the throttle to accelerate in the end!
The meaning of heel movement?
Everyone knows that because of the difference in the gear ratio between gears, there will be a difference in speed when the cloud is done. The heel-to-toe action is to decelerate the field, and the gear is used to reduce the speed difference to reduce the speed difference so as to achieve smooth and rapid reduction. The purpose of the block. Assuming a car with a gear ratio of 3.6% and a second gear ratio of 1.8, the current engine speed is 3,600 rpm, and the output shaft speed of the transmission is 3,600 ÷ 1,8 = 2, 000 rpm. If you want to reduce it to the first gear and keep the output shaft constant at 2000 rpm (the speed of the output shaft of the transmission must be kept stable during extreme travel, otherwise it will cause the instantaneous friction between the tire and the ground to change instantaneously, causing a loss of control). The engine speed must be at the peak of 2000×3. 6=7200rpm. This is the meaning of the action with the toe: downshift replenishment to maintain the balance of the body. When practicing Heel Toe Action, you must first find a car with a suitable pedal position. The pedals must not be too far apart, and the high and low positions must be almost identical to facilitate heel toe movement.

(C) left foot brake action LEFTFOOTBRAKE
I have already said that the important role of speed, the left foot braking technique explained here is just invented to keep the speed and the tire's grip.
How to make a left foot brake?
There are many factors affecting the cornering speed of a car. The most important thing is the cornering line, followed by the grip of the tire and the power output of the engine. When the driver ran into a corner with full throttle, he found that his slight speeding caused a slight understeer. This lack of point is not worth the driver's right foot to give up and accelerate to concentrate on braking, so he madly step on the accelerator while Use the left foot brake to correct the route. The left foot brake is widely used in various field races and rallyes all over the world, especially for FF (front engine, front wheel drive), MR (middle engine, rear wheel drive) and 4WD (four wheel drive) models. .
As long as you have a good grasp of the strength of the left foot brake, the action of the left foot brake is relatively easy to do, but in actual driving, with the left foot brake, how much should be done? The question is worth considering.

(D) Two-leg clutch DOUBLECLUTCH
The previous gearbox had no synchronizer, and there was a bit of speed difference between the gears that couldn't be changed into the gear. The two-leg clutch was the trick that everybody would be able to use. The two-legged clutch was slightly more complicated than Heeltoe. First release the accelerator pedal, depress the clutch pedal, change to neutral, then release the clutch pedal, make up a foot of empty oil (if it is an upshift, then do not need to make up the oil), and then depress the clutch pedal again to lower the first gear (or Raise the first gear) and release the clutch pedal to end the action. The two-legged clutch is now also one of the defensive skills of the field game, and has the same effect as the heel action. In actual driving, it doesn't matter if you don't do two-legged clutch. Just remember to make up some oil or stay in neutral for a moment while shifting. This action is a great help to protect the gearbox.

(five) with the toe, two feet mixed method
After all, the road is different from the stadium. There is not much opportunity to do heel-to-toe movement on the highway. It is not necessary to do two-legged engagement, so I have developed a simple and easy-to-use deceleration technique in practice. The method is as follows: when decelerating, depress the brake pedal first; when the brake is over, depress the clutch pedal; hold the shift lever in the right hand and shift into the neutral gear; the right toe simultaneously leaves the brake pedal, depresses the throttle replenishment, releases the accelerator pedal, and quickly rotates the right hand. Lower the first gear, finally release the clutch, and press the throttle. This trick is extremely easy and has a certain effect. Although it is less professional than the other two, it is enough for daily driving. Heel movements, left foot brakes, and two-leg clutching actions each have their own characteristics and application areas. I will not introduce them one by one. I believe that you will realize that their driving skills will make them realize their uniqueness.

(six) train feeling
The sense of the car refers to the driver's familiarity with the car and the driving feeling. A qualified fast driver should be able to sense the change of the grip of the car tire at any time and be able to think of the position and width of his car body at a crucial moment without hesitation and complete various Difficult movements.

(7) Authentic Heel + Legs are legal
This action does not have any false flowers, it is to do the standard Heeto action at the same time with the two-leg clutch. The method is as follows: brake braking, stepping on the first leg clutch to reduce the neutral gear, releasing the clutch, and then stepping on the clutch again almost at the same time and doing a heel action to reduce the target gear. 6park. In the past when there was no gearbox and no synchronizer, some talented riders made a living out of it. However, nowadays, with the toe action, the clutching movement is enough to make your heel movements smoother and also to make your feet look more beautiful.

(8) Fasten the seat belt
Is the seatbelt a driving skill?! Yes, it is a very important driving skill. In the fierce driving, the rider's body will always be shaken and shaken right away due to various powerful forces. It is impossible to drive safely and the seat belt will play a role at this time. When the body is tightly fastened to the seat by the seatbelt, the driver can use 100% energy to cope with the driving and increase the speed without worrying that the unprofessional seat can't contain himself. None of the world's car races are not belted. So, even if it is to experience the feeling of professional drivers, please attach your seat belt!
