Fast driving is all about maintaining the balance of the car when turning, skidding or braking, When you use double clutching technique to change to a lower gear you will firmly be in control of your vehicle even at a higher speed.
Before car engines could accurately match the speed of the gear to that of the shaft, a double clutch shift was normal when driving. With the advancement of technology from manual to automatic transmission double clutching has been relegated to motor racing. Double clutching means both of your feet are working in harmony between shifting gears and accelerating the car.
This takes us back to the main question, what is double clutching?. This is a technique of moving gears from high to low or low to high enabling a smooth prolonged transition, it is quite common in motor racing where overtaking at high speed is the norm.
Why Do You Need Double Clutching
#1. Smoothness of transmission
This is very vital if you are going to move from one gear to the next by skipping one in between especially if you want to move to a lower gear to reduce speed without slamming on the brakes. In normal circumstances trying to skip a gear when downshifting results in a jerky movement which will eventually slow you down or even stop the car.
#2. Prolonging Transmission
Moving a gear from one to the next always delays for a moment before the synchronization can take place. This waiting moment is not a good idea when you are in a competition because it will cost you a lot of time. Double clutching ensures a smooth transmission.
#3. To Maintain Speed
You need to do a double clutch to make sure that when you are downshifting, the driving speed remains the same. This will match up the gear box and the car’s acceleration.
How To Double Clutch
You would normally start off your current gear. for example, you want to move from one gear to the next as is expected engage the clutch but before you move on to the next gear you leave it at the neutral position and then shift to the next gear in one smooth operation.
1. Shift the gear position to neutral and release the clutch pedal from your foot.
2. Press down on the accelerator pedal with the car still in neutral gear to increase the RPM’s (Revolution Per Minute), when the RPM is higher than the expected at that particular gear position, the transmission speed will be equal to the engine speed.
3. Take your foot off the accelerator and push in the clutch one more time ( remember this is the second time you are doing this before moving to the next gear, hence the term double clutching).
4. Shift the gear from the neutral position to the next (usually lower in double clutching) gear.
5. Let go off the clutch as soon as you engage the new gear ( this should be done very fast)
6. That’s it, you have just done a double clutch without any special training, all you need to do now is more is practice.
NOTE: You can also do a double clutch move when shifting from a lower gear to a higher gear but when matching transmission, your RPM should be lower when shifting.
Getting it Right
Double clutching is more useful in a racing environment than you would experience it driving a standard car. The emphasis is on how low or high RPM’s should be before the next shift.
Whenever you release the clutch before moving on to the next gear, make sure your RPM’s are high enough to avoid the ‘tug’ every time you change gears. Aim to strike a balance between the two feet and the hand shifting gear. Try to be easy as possible on the shift, do not force it in.
You should not experience any resistance, doing it right simply means moving from one gear level to the next in one smooth transition
Understand and know the limits of your engine before attempting to do a double clutch. Some cars tend to have lower RPM range than others.
The clutch has got springs that will engage and disengage during operation. Using light pressure while double clutching may not engage the gear, this will end up grinding you gear. While at the same time if you apply too much pressure, the clutch brake will be engaged and will slow you down for a while before fully engaging the gear. For you to be able to get this right you need a lot of practice so that you know the correct amount of pressure to apply.
Practice and more practice should not discourage you from getting the hang of it, the earlier you get it right, the better it is for your gear box.
The main debate is whether double clutching should be part of any modern car designs. I have a feeling that with the increasing number of tuned up engines that can drop their RPM’s faster than an ordinary car, the racing industry cannot do without this technique. For the experienced drivers, this is the best way to keep your car in a good working condition.
