Rev-Matching Gear Changes In A Manual Car | Learn to drive: Expert skills

- Опубликовано: 9 мар 2017
- Changing gear smoothly is an important skill for the driver of any car with a manual gearbox, but sometimes it can be difficult to change down to a lower gear without that annoying jerk as the clutch is released. A driver that can use the accelerator to match the engine speed to the road speed when changing down, will achieve a much smoother gear change - this technique is called ‘rev-matching’. This video will look at why it is difficult to change down smoothly, show how 'rev-matching' can help with this problem, and also where we can use this technique.

I passed my driving test 37 years ago, I had never heard of this technique before, it goes to show you that learning never stops.
😂 I just learnt now after 5 years. I was watching a video and the guy was talking about rev match, so found this. Everyday is a learning day.
"Your driving doesn't make me feel dizzy" and "It feels like an automatic" were the most positive comments I got from my mates after I practiced and applied rev-matching. Your videos have helped me a lot when I was preparing for my practical driving test and more so today as I continue to improve my driving skills. Thank you very much.
after using this tehnique my passengers noticed really smooth drive, they even thought I have done something with a car to drive more smoothly, thanks for this
Awesome! Good stuff man
Good advices for this technique. I've always wanted to know the basics of rev-matching and this video helped me! Keep on going guys
+Jose Luis Gallardo Glad you like our video - we hope it helps improve your gear changes!
I've watched many rev matching videos and this is by far the easiest way to understand,thanks for sharing
Thank you very much for this detailed video. You've explained beautifully. Keep the videos coming. Subscribed :)
Fantastic! Just what I needed. Really great videos for beginners and more experienced drivers, like me. Many thanks.
+FunkyFlunky Thanks! We do our best to help 😃
You should also explain how to rev match when going up the gear box to complete the video. Overall - good stuff! Well done, guys! Keep doing it! The voice is pleasant :)
very through and comprehensive....learned driving only with these videos.....thank you so much guys and please keep it up
conduit facile sometime can be even succinct :)
Fantastic explanation.
Very good explanation! Thank you for sharing! Double clutching would be a nice addition to the rev matching video :-)
You make driving easy and understanding.
Many thanks again, I love the way you guys explain even the small details, I’m a Romanian but I send you Greetings from Germany !
Super good content ! 👌

Prefer to "sustain rev." gear change rather than "blip"- i.e. maintain/apply constant accelerator pressure, de-clutch & select lower gear then let in clutch smoothly (still maintaining the "gas"). As an old school advanced sort one doesn't overlap braking & changing down - thus negating heal & toe considerations -& keeps both hands on the wheel while the car is de-stablised under braking (this doesn't preclude de-clutching before braking is completed if the engine might stall or taking 1st just before a stop nor would it apply down hill - here just let clutch in slowly against the idling engine).
It's been 2 years since I watched this video. I learned how to blip my car's throttle a bit and facilitate step-by-step downshifting from 4th to 1st gear while slowing down at a steep junction (but without using heel-and-toe technique, though). Plus, I've been using a higher RON petrol on my entry-level car for quite some time which surprisingly help the engine to maintain its speed, torque and momentum, thus making prompt downshifting during rush hour traffic in busy streets and steep roads a bit smoother similar to doing a rev-matching technique.
Thanks for the comment - it just goes to show that there is always something more to learn!
Thanks for this helpful video!
Thanks so much for the educational videos...
This was superb
All your videos are well made and explained gently.
Subbed! Great stuff guys. I miss driving in England. I'm a crap driver now because I've lived in Perth for too long. Huge roads. Huge parking spaces. Too many automatics. :D
+Chris Winter Thanks - as you can see, we have plenty of tight and twisty roads here for us to practice with!
Thank you so much clears so much
Excellent videos
as I m a new driver driving from last 1 year so how to shift smoothly if not to use this technique sometimes changing into upper gear is also not smooth and every time changing into second gear before taking some turn is never smooth
Only use rev match throttle when clutch is fully disengaged (pedal fully down). When you’ve added some revs by pressing the throttle, then let your clutch out to ‘catch’ those revs.
This is certainly useful if you are doing some pretty hard driving or a big downshift in circumstances where you can’t afford to use a bit of time with the clutch down and braking to help get you in rev range.
If you are doing normal driving, or indeed if you don’t need to downshift quite abruptly, then you can also just put your clutch down and let the revs drop (but I’d advise moving your gear shift through the gears at the appropriate times just so you could come off the clutch into the right gear if needed).
Also, for nice smooth shifts, just come off the throttle for a moment when you put the clutch in, and after you’ve shifted and your clutch is just starting to come up, press down a bit on the throttle in equal measure to just help smooth it out.
To help grow as a driver and develop feel, try to find for each gear (and under which road conditions such as incline/decline and speed) how far the clutch should come out before adding throttle (as it will vary slightly for the optimum) and in each case also how much throttle is best and when it is best applied, and also how slowly to come off the clutch.
First to second can be hard for people to make smooth and steady, so try giving a bit more throttle and really taking your time with the clutch.
nice video
I have used this technique for the 7-8 years of driving a manual car without knowing there is a term for it. 😀😂 Also, I didn’t know the rationale behind it.. I just learnt with experience that THAT is the smoothest way to shift gears so much so that it became an automatic habit.
Have you ever tried this technique? Heel & Toe Rev-Matching: ruclips.net/video/nkKV8ZFEVRg/видео.html 👍🏼
Never heard of this technique before. I'm going to try it during tomorrow's lesson. Hope I don't die...
We put this video in our 'Expert Skills' playlist, as we suggest it is best left for after you have passed your test. However - if you're feeling confident why not mention it to your instructor, as once mastered it will really help with smoother down-changing!
Advance Driving School Will do, ta!
Thanks
Awesome video as always
Would you guys consider doing a heel-toe downshift tutorial?
+Nathan Pollard I feel that technique should only really be used on track, so wouldn't recommend it to inexperienced drivers on the road. Sorry
i thought the same for many years, so i didnt practise and never used it. But for almost a year now i have a car that has a lift off oversteer character and old brakes, clutch etc (a '93 peugeot 106 xsi) and it is also good for driving pleasure, and i start learning (with youtube instruction videos) and using it in every days driving. I practise it while braking in almost every traffic light, letting space in front of me. Now i have more control of my car and i use the engine braking correctly while braking so i save my pads and clutch and i have always control of the cars behavior (always on a straight line). It is not so difficult if you practise the right foot moves in neutral at the beginning , after at traffic lights and then mastering it before a corner entry. I find simple rev matching usefull goind uphill or where is no need for braking, and heel toe better at braking (no need to let the brakes to change gear means better control and better braking distances). I totally agree however with the inexperienced part of your reply
@@AdvanceDrivingSchool It seems it only took 4 years to change your mind! 😆
@@RealizeEditing1 Heel & Toe Rev Matching: ruclips.net/video/nkKV8ZFEVRg/видео.html 👍🏼
@@AdvanceDrivingSchool Great stuff thank you!
Hello! Nice video, I think it's very clear. But i have a doubt/ question: I have seen you pressing the throttle when the gear was already in the new position, Would it be better in any ways to press the throttle while you are in neutral gear before you move to the wanted gear? i'm not sure if made myself clear. Thanks!
+Alejandro bermejo lozano In practice it doesn’t matter, since as the clutch pedal is pressed down fully all gears are disengaged anyway. If we pressed the throttle whilst the gear lever is in neutral, by the time we then selected the next gear the revs would have dropped back to idle speed again. Timing the ‘rev-match’ perfectly is key to making it work, and I think you’ll just have to practice until you get the hang of it 👍🏼
Great video! I think I read something similar in The Official DVSA Guide to Driving: The Essential Skills. However, just one question - what do you mean by "matching the engine speed to the road speed"? I'm still learning to drive, so not sure if it's something obvious that I just don't know about yet. Is it that the number of revs should be approximately the same as the road speed? So, 20mph - 2000 revs, 30mph - 3000 revs, etc.?
Thanks!
If only it was as simple as that - but unfortunately since there are so many variables (such as gear ratios etc) the exact amount of engine revs needed to match the road speed will vary between cars. This video is in our 'Expert skills' playlist as it is intended for after you pass your test - whilst learning to drive we wouldn't recommend you even worry about this for now.
@@AdvanceDrivingSchool Thanks for the super-quick reply!
So, essentially, this is something that you have to develop a feel for, and it will vary depending on the car you're driving. Good to know!
Thanks!
You can get relatively smooth gear changes when changing down from a higher gear by releasing the clutch even slower?
Yes, the easiest way to get a smooth down-change is to slow the car, then release the clutch really slowly. Save experimenting with ‘rev-matching’ until after passing the test when you have more experience.
@@AdvanceDrivingSchool Yes, this seems correct releasing the clutch slowly, but I am concerned how much wear this technique causes to the clutch.
Can u do heal and toe ??? I want to learn that as it's more useful for everyday driving
Heel & Toe Rev Matching: ruclips.net/video/nkKV8ZFEVRg/видео.html 👍🏼
I did lesons with LDC driving school and they never taught me to rev match, I only realised it was a thing today more than 3 years after passing my test
That's perfectly normal - as it's not necessary for safe driving and would add more time to your driving lessons. We have put it on our 'expert skills' playlist for people that have already passed - as it's the sort of skill that you can perfect on your own. Have fun!
Hi! What do yo you think, if I firstly depress the throttle and after that release the clutch - it is not bad? I just can't understand why people blip the throttle instead of smooth depressing before clutch in.
Either technique is fine, just do whichever you find easier 👍🏼
When you release the Clutch after revving the engine to match road speed, are you supposed to apply gas again or should it be smooth just releasing the clutch and letting the high rpm from the rev fall down to whatever engine speed it needs (Hopefully this makes sense!)? Every time I shift up, I need to give some gas whenever releasing my clutch or else the car jerks!
We normally only rev-match when changing down gears, and we only need to press the accelerator once for a smooth gear change. When changing up a gear, there is no need for a rev-match if we time the gear change correctly. Keep practicing 👍🏼
clutch, gear change, then rev
Interesting technique! But I think frequent rev matching, especially to much lower gears, can increase fuel consumption.
+Sathyadeep Viswanathan It must use a little fuel of course, but that is offset by less clutch wear and increased passenger comfort!
The fuel used to rev match is negligible.
Question: say I'm slowing down so I put the clutch fully in and brake a bit, but then I want to get moving again quite quickly, usually I would have to bring the clutch back to the bite point for a bit and add gas to accelerate, would a rev match help me move off quicker? (i.e would I be able to come off the clutch quicker, since the clutch has to do less work in increasing engine speed?) Would heel toe be applicable there? Thanks
There is no need to push the clutch when braking, unless you are changing gear or about to stop. Also, we consider rev-matching as unnecessary until after you have passed your test and have more experience.
@@AdvanceDrivingSchool ah ok thanks
Please correct me if I'm wrong. In some videos, I saw drivers first press the clutch then 'blip' the throttle, then change gear and finally release the clutch. But in the video, you clutch in first and then change gear as normal AND lastly 'blip'. Are they the same thing?
It’s just the way each driver prefers to do it - a bit like different steering techniques. Try both and see what works best for you 👍🏼
@@AdvanceDrivingSchool Thanks mate.👍
If ur breaking before downshift. ....and pressing clutch at 1200 rpm to downshift the gear.....I don't think u need to blip the throttle. ....the clutch will do the Rev matching as ur changing gear at 1200 rpm.....where as if u want to maintain same speed when driving at high gear and then want to shift down a gear..then blipping the throttle a.k.a rev matching should be done.....
I'm still not very experienced but instead of doing this, could I just slow the car down more before downshifting?
We don’t recommend inexperienced drivers should try rev-matching their gear changes, but instead just slow down more before a down-change as you suggest. This skill (and others in this ‘expert’ playlist) are best left for after the driving test has been passed and more experience has been gained 👍🏼
Advance Driving School thanks!
based on this video it seems like rev matching is mainly used when shifting down 2 or more gears. Does it not matter when only shifting down 1?
+Chew It is most useful when shifting down 2 or more gears, as this is when there is the biggest mis-match between the engine and wheel speeds. However, unless driving slowly I usually rev-match all down shifts for added smoothness!
The revs needed depend on the gear selected and the speed of the car, so there is no exact answer. For example if we are changing to 2nd gear at 30mph in my car it would need about 3000rpm, but at 25mph only 2500rpm. Other gears will need different revs at different speeds, and of course it will also vary between cars - as the gearbox ratios will be different. You’ll have to experiment!
So i should do a rev match when the engine speed goes down to 1rev per min?
Do the gear change when you need to for the corner / junction etc - the rev match should help at any engine speed.
What do you mean by "road speed" in the video. Please elaborate!
By ‘road speed’ we mean the speed the car is driving along the road 👍🏼
Little teaser for the heel-toe at the end
Heel & Toe Rev Matching: ruclips.net/video/nkKV8ZFEVRg/видео.html 👍🏼
Can you rev match from 2nd to 1st? As i feel like the car is not moving at all (or feels like doesnt want to move) when i downshift from 2nd to 1st gear on very tight turn.
In theory you could rev- match into 1st, but we find it easier to stay in 2nd and use a little clutch control to drive slowly.
I know what you mean... Am a beginner myself and yes the car just stops(doesn't stall)...yes you can use clutch control but if you feel you absolutely need to shift down to first, then yes a slight blip will help you keep momentum
You 100% can, and i do.
I'd master the other changes first, and then try first gear rev matches after you're comfortable with the concept.
It's a great feeling when you match a gear perfectly. Makes you better than 95% of other drivers on the road.
hello i am a learner driver should i use rev match when going down gears
No - it’s unnecessary to learn that before your test. Perhaps consider it when you have more experience 👍🏼
What is he doing at 5:00-5:02 ? Is he using double-clutch for rev-matching when doing downshifting from 4th to 1st ?
I find double-clutch technique is the only satisfying method when skipping more than one gear such as from 5th to 2nd. The basic single-clutch technique may end up with juddering on my engine at times.
+Lex Soft With modern cars it really isn't necessary to use the 'double de-clutch' technique. If timed right, there is no problem changing from 5th to 2nd without any juddering in our cars. If your car doesn't like missing out 2 gears, then just miss 1.
+ADS
You still don't answer my question on what the driver was doing at 5:00-5:02. Or you implicitly have answered it ?
Regarding my problem on downshifting from 5th to 2nd using a usual single-clutch : maybe it's because I don't do it correctly or because my car is a Nissan Sunny 1997... :)
But I don't want to put blame on my car as it has been serving me very well since I bought it last year in June to learn more on how to drive a manual car... :)
+Lex Soft Sorry - at 5:00 I am just down changing into 1st gear normally as the car speed was down to about walking pace, and I needed to pull away promptly.
Older cars are often a little different to drive, compared to newer models - but after a little while you get used to how it likes to be driven. 👍🏼
+ADS
Thanks again for replying.
I am still very confused when is the right time to rev up?
In some videos they do it BEFORE, while still in higher gear, you do it AFTER, when we're already in lower gear. Meanwhile, what makes most sence to me is to do it half-way, to ease the stress on synchros,though I might be completely wrong.
So, which one is best, and why? I really hate doing it in higher gear, as it requires high rev and racing-fast gear change, which I really don't want to do.
Either is fine - just experiment and see what works best for you!
Oh, and in case you haven’t seen it already - we recently made this video: Heel & Toe Rev-Matching: ruclips.net/video/nkKV8ZFEVRg/видео.html 👍🏼
@@AdvanceDrivingSchool Thanks, well your late method makes it easiest to pull off a smooth downshift, while mine midway definitely gives lees resistance when pushing in lower gear. For now, I'm doing my way for easy revmatch shifts, like 5-4 and 4-3, and yours for difficult ones, like 3-2 and 2 gears down. So far seems ok. :D Reving while still in higher gear and then shifting quickly enough and not dropping too much rpm seems to difficult and tense.
@@millancche How quickly do you release the clutch pedal when rev matching?
@@theman3923 well, pretty quickly, much faster then while doing a regular start from gear 1. About as fast as I do with regular upshifts. That good or not?
So is it not bad for my clutch when i press clutch all the way down nd press little bit gas to rev match
The clutch is tougher than people think - ours always last at least 100,000 miles, even with all the driving lessons we do!
I use rev matching when I downshift on a highway, to get more power out of the car. I'll test the downshift rev march technique
Will this work on 2015 Mazda 2? Some day rev matching only for older cars, is it correct ?
It should work in any manual car, new or old / petrol or diesel. I do it all the time in our 2018 Ford Fiesta 🚙👍🏼
Thanks a lot
Blip or changed gear first? What would be the proper way to revmatch?
You need to do both at the same time - watch my feet to see how I do it 👍🏼
@@AdvanceDrivingSchool you changed gear first then you follow it up with a blip? Not at the same time.
King Harry Motia you can either blip as you cross neutral or after you switch gear (downshift), as long as the clutch is pressed all the way down
Lmao I instinctively do this 😂😂
Good for you
i was rev matching on my driving test
lol you're crazy. Did you pass though?
Zhin Null I’m actually curious
So did I. The examiner actually complimented me on it lol
Lol same
is it necessary to get off the accelerator before applying the clutch?
At the start of the gear change - yes, otherwise the engine will over-rev once the clutch disconnects it from the gearbox.
@@AdvanceDrivingSchool okay, thanks!
Can I do blockchanging all the time without rev matching ? Is it good to do so in any car ?
Most drivers don’t use either technique - but you are free to use either or both of them whenever necessary in any car.
Next week, heel toe downshifting and how to burnout!
+Qasim Mir I'm sure there are other channels that can help with that stuff, but it doesn't sound like safe driving to me!
I'm not sure that I really agree to be honest. There aren't really any 'unsafe' aspects of heel-toe downshifts at all, and the technique undeniably increase your control over the vehicle. The only unsafe aspect I can really identify about heel-toe is the process of learning it. The introduction to the technique can be learned in a safe and controlled environment, and once the driver is comfortable and confident, it can be utilised on the roads. In your video you identify heel-toe as being an 'advanced technique' which I personally think could be deemed to be quite appropriate for the 'Advanced Driving School' channel, could it not? To be honest your argument kind of boils down to the equivalent of 'Learning how to operate a car isn't safe, because an accident could happen!' There is an element of danger in everything you do...
Qasim Mir 😂😂😂 please tell me that was a joke 😂
I heel toe on the road :)
I'm a taxi driver and my customers (Esp the girls) love the smooth ride. I use this technique 95% of the time. Good tip earner hehe.
Would it, in theory any how, help prevent stalling?
+happygoluckyscamp Not really, as since the car is rolling there isn't any danger of stalling in this situation. This technique is definitely best left until a driver is fairly experienced 👍🏼
Ah right. Just, I've started stalling during lessons....I think I might just be over reacting as I'm getting bombarded with information from my....not instructor but family member that isn't giving me practice so much as connived that they're teaching me.
It's not easy for a family member to teach someone to drive - but it is a lot cheaper for you! Maybe suggest they take it easy with you for a bit...
Next, heel and toe rev matching.
Heel & Toe Rev Matching: ruclips.net/video/nkKV8ZFEVRg/видео.html 👍🏼
do you tap the accelerator or fully press the gas pedal to floor when rev-matching?
+Daniel Mauchaza Just a gentle push or tap. We only want the engine revs to rise enough to match the speed of the lower gear. Experiment until it feels smooth!
Daniel Mauchaza I usually tap it twice cause I have a lighter flywheel then normal people.
There is no need to rev-match when shifting up as the engine speed and car speed match quite well anyway, which gives a smooth gear change.
Fully press
I think you can use both methods. I press on gas pedal when releasing the clutch pedal. It depends if your coming to a round about or driving on an A road when traffic has slowed down a bit.
Can we from 4th to 1st without any jerk?
Yes, in theory - however it’s not something that should normally be needed. We would usually use 2nd gear as well to give extra engine braking as we slow down. Give it a try and see what happens!
I have tried to do this technique but can not for the life of me get it right so I give up
I had been driving for over 10 years before I even tried to do this - and even then it took a while to perfect!
Heel & toe downshifting will do the trick
Heel & Toe Rev Matching: ruclips.net/video/nkKV8ZFEVRg/видео.html 👍🏼
Is this only for downshifting??? Pls reply
We reply to every question! Rev-matching is only needed for down-changes, as up-changes are naturally much smoother.
Advance Driving School thank u.... 👍
You using black shoe we can't clear see your actions
In-fact you can rev match upshift's - ease off but don't release the gas -revs will fall but only enough for the change e.g.30mph in 3rd say 3000RPM to 4th 2000RPM. The advantage being you can change more slowly/gently (-without the rev match you must change qickley with a snatched action to catch the falling revs especially with to-days light eco. fly wheels,) the result is an upshift smoother than the best auto 'boxes & extended synchromesh life .@@AdvanceDrivingSchool
4th to 2nd is that a thing?
Block Gear Changing: ruclips.net/video/oI2kN1IvNnc/видео.html 👍🏼
Half of the manual car community says downshifting revmatching is essential and should be done Everytime you shift down So what's the correct way because I'm sick and tired of this argument. I'm self teaching myself stick in a ND mx5 because I have no friends ( I like being by myself) and no one in my family knows stick. I've just been watching videos after videos after videos on stick tutorials. Half of the videos say downshifting revmatching should be done when downshifting. So I'm like WTF is the correct way to shift down. I've been driving for a year now on my ND and I just finally are getting better at upshifting but down shifting is where I don't know what to do. I've tried to just shift down without blipping the throttle and I buckle the car but the car buckles really hard alot. So what is the correct way to downshifting?
The answer depends! When a new driver is learning to control the car we never even mention 'rev-matching' as it just makes everything harder. Down changes can be made smoothly if the car is slowed down to the correct speed, and the clutch is lifted slowly. Most drivers will stay with this method for ever, but when a driver gets more enthusiastic they soon realise that they can't downshift smoothly at higher speeds - and then rev-matching becomes more useful as it allows a smooth gear change at any speed. This is the reason that we have put this video in our 'Expert Skills' playlist, as it should be left for more experienced drivers - but even then it will take a little practice!
Why the crap they changing the gear before the gas? Ok you save the clutch but what about the gear??
Can you rephrase that? Doesn't make a lot of sense what you typed out, because you're just describing normal upshifting.
Heel toe!

@@AdvanceDrivingSchool do you think this delicate maneuver is necessary for the casual daily driver and or keeping the car in relatively good state - specifically the clutch?
No - this technique is almost completely unnecessary! 99% of drivers don’t use this method and manage just fine - but for the other 1% it is satisfying to master and genuinely useful. 🚙👍🏼
@@AdvanceDrivingSchool great! I'd want to be in that 1%!
4:58 "It is even possible to rev match while _______ the car." WTF did she say?
“It is even possible to rev-match while braking the car” - you can see me do it in this video: ruclips.net/video/yY81aE-IeIQ/видео.html 👍🏼
You should change gear at 2.5k revs in a petrol car
We think that depends on how much power is needed. When driving gently, we won’t need much power so can change gear quite early for best fuel economy. However, when we need extra engine power, such as when accelerating up to speed on a major road we would change gear much later.
