Double Clutching Vs Rev Matching: An In-Depth Comparison

Double clutching is a technique used in manual transmission vehicles, while rev matching is a technique used in both manual and automatic transmission vehicles to smoothly downshift. For drivers who love manual transmissions, double clutching and rev matching are two essential techniques for a smoother ride.

Both techniques are used when downshifting, but they differ in execution and purpose. Double clutching is a technique that requires the driver to push in the clutch pedal, shift into neutral, release the clutch pedal, push in the clutch pedal again, shift into the lower gear, and release the clutch pedal again. This is done to match the engine speed with the lower gear, avoiding jerky downshifts.

On the other hand, rev matching involves a simple blip of the accelerator pedal to match the engine speed with the lower gear before releasing the clutch pedal. In this article, we’ll discuss the differences between double clutching and rev matching and when and how to use these techniques to improve your driving experience.

Double Clutching Vs Rev Matching: An In-Depth Comparison


What Is Double Clutching?

Double clutching is a technique that involves shifting gears twice, once to neutral and then again to the desired gear, in order to precisely match the rotational speeds of the engine and transmission. This is done to ensure a smooth, seamless gear change that doesn’t put any undue strain on the vehicle’s transmission system.

How Does Double Clutching Work?

Double clutching involves taking the manual car’s transmission out of gear, in the neutral position, and then depressing the clutch pedal to disconnect the engine from the transmission. This allows the driver to rev the engine up or down to match the speed of the wheels.

Once the engine is at the right speed, the driver moves the gear shift to the next gear and releases the clutch pedal to engage the new gear.

The Benefits Of Double Clutching

Here are some benefits of double clutching:

  • More precise gear changes that don’t put strain on the transmission
  • Can help extend the life of the clutch and transmission
  • Useful for racing or aggressive driving to reduce the risk of transmission damage
  • Can help reduce jerky movements while shifting gears, making the ride smoother

Examples Of When To Use Double Clutching

Here are some situations when double clutching can be particularly useful:

  • When driving uphill or downhill
  • When the transmission is cold or the vehicle is new
  • When shifting between gears that have a significant difference in speed

How To Execute Double Clutching Effectively

To execute double clutching effectively, follow these steps:

  • Take the vehicle out of gear and hold the clutch down
  • Move the gearshift to neutral
  • Release the clutch, rev the engine to the appropriate rpm, and then depress the clutch again
  • Move the gearshift to the next desired gear and release the clutch again

Common Mistakes To Avoid While Double Clutching

Here are some common mistakes to avoid while double clutching:

  • Revving the engine too high or too low while the vehicle is in neutral
  • Releasing the clutch too quickly or too slowly, causing a jerky gear change
  • Not fully pressing down on the clutch pedal while shifting between gears

Double clutching is a useful technique for manual transmission drivers who want to reduce wear and tear on their vehicle’s clutch and transmission. Follow the steps outlined above to execute double clutching effectively and avoid common mistakes that can cause harm to the vehicle.

Mastering this technique can lead to a smoother, safer, and more enjoyable driving experience.

What Is Rev Matching?

Rev matching is a driving technique used to match the engine speed of your car with the speed of your transmission during a shift. It’s a method that mainly involves downshifting and blipping the throttle while braking. The result is that the engine produces the correct amount of power needed during the shift, making the transition smoother.

How Does Rev Matching Work?

The rev matching technique involves three main steps:

  • Releasing the clutch: at this stage, you need to remove your foot from the clutch pedal while braking.
  • Blipping the throttle: blipping the throttle involves pressing the gas pedal to raise the engine revs slightly.
  • Engaging the lower gear: once the engine rev matches the transmission’s speed, slowly engage the lower gear.

The Benefits Of Rev Matching

Here are some of the benefits of rev matching:

  • Smoother gear shifts: by matching the engine and transmission speed, the shift will be more seamless, preventing any jerky movements.
  • Reduced wear and tear: rev matching reduces the strain on the clutch, gearbox, and other essential components, resulting in less wear and tear.
  • Increased control: rev matching enables the driver to have greater control of the car, thus decreasing the possibility of locking up the wheels or losing control of the car.

Examples Of When To Use Rev Matching

Here are some scenarios where rev matching is helpful:

  • When shifting gears on a twisty road: rev matching will help maintain the car’s balance as you downshift while navigating a winding path.
  • When entering or exiting a turn: rev matching can help you prevent losing traction and maintain the right gear as you exit or enter a turn.
  • When driving downhill: rev matching can help maintain the car’s speed and traction as you navigate a downhill slope.

How To Execute Rev Matching Effectively

Follow these steps to execute rev matching effectively:

  • Decelerate: reduce your speed as you approach the corner by either easing off the throttle or applying the brakes.
  • Clutch in: press the clutch pedal down to separate the transmission from the engine.
  • Preselect your lower gear: select the lower gear early in the braking zone.
  • Rev match: blip the throttle to match the engine speed to the transmission speed.
  • Shift: once the engine speed matches the transmission speed, engage the lower gear.

Common Mistakes To Avoid While Rev Matching

Here are some common mistakes to avoid while rev matching:

  • Over-revving the engine: rev matching involves blipping the throttle just enough to match the engine and transmission speed. Over-revving the engine can cause unnecessary wear and tear on your car’s components.
  • Not braking enough: braking is essential while rev matching to control the car’s speed and prevent the wheels from locking up. Not braking enough can cause you to lose control of your car.
  • Poor timing: timing is critical when rev matching. Improper timing can lead to jerky movements, resulting in a less smooth ride.

Rev matching is a valuable driving technique that can make your driving experience smoother, reduce wear and tear, and increase control. With proper execution and practice, mastering rev matching can elevate your driving skills to the next level.
