Glad I found this and you are teaching people about it as I learnt this rallying many years ago.

And the most important take home message with this. Avoid braking into a corner especially if the road is slippery due to weather conditions or loose material on its surface. I played a game recently on a journey with multiple particularly twisty stretches of roads. How many drivers actively brake whilst cornering, and I mean proper corners where the car would certainly be significantly unbalanced. I reckon 80% of drivers where doing so. Modern cars with modern traction control technology are certainly helping these drivers but perhaps with a detrimental effect of making them much poorer, dare I say lazy, drivers.

Whilst sat of my sofa im trying to think to myself whether i do this myself or not. Maybe i do, maybe i dont but i think this is the first time this has been its been explained to me in this way so i shall be mindful of this, thank you.

Loving these. Top advice 🙌🏻

I’ve become a much more competent driver since watching your videos Reg, I’ve learned so much, I passed my test about 40 years ago! You’re never too old to learn.

Thank you, Reg very informative I love my driving and try to improve every time I'm behind the wheel. Great tips on setting the car up, it's all about driving smoothly at different speeds.

Very well explained and very easy to understand. Balance is so important :)

Another successful informative video Thank's

A very clear explanation - many thanks. I'd be very interested in a similar video for bikes.

Gave it a try last night in my front wheel drive motor. Car feels more balanced & settled. Top advice, please upload a few more. I’m a biker too so know all about vanishing points in your previous video, but still lots to learn. Great content, keep up the top work, and thanks 👍😎

Thank you for the detail explanation. It's very useful on mountain roads driving!

This is brilliant Reg, I'll let you no how I get on with my new JCW.

ngl a lot of this stuff is second nature to me but it is all good to be more conscious of i love the way that camera is mounted btw i feel like it gives you a lot of an understanding of how the car handles compared to most videos honestly that is what they need in car reviews 7:21

I just came across your channel. Invaluable content that I have been looking for. Thank you so much for the great videos.

Great video Reg thanks. I think the point you make starting around 10 mins is key. If you don't apply power in a turn, the friction of cornering will slow the car which uses some of the available traction that you need for lateral grip. That injection of throttle makes a huge difference.

I found this really important in a rear wheel drive with a mechanical LSD. You need to get even 2% on gas at corner entry, or face a horrible change of attitude as you go from - to + throttle. Then never lift! A good example of how secure a car can feel using this technique, that everyone should be aware of, is that your car will always feel WAY better turning in a compression, than turning over a crest. Nice video. These should be compulsory 🤓

Excellent video these are brilliant as I'm getting closer to my advanced driving test with IAM 👍

Great video thanks

A significant component of the 'weight shift' during braking and accelerating is the change of angular momentum of the wheels and tyres. Angular momentum has to be conserved: when the car tries to slow the rotation of its wheels, the car itself tries to rotate around (particularly) its front axle. That's why the rear of the car "goes light" and the car tries to "stand on its nose" during harsh braking. If a wheel balancing machine weren't fastened to the floor when it stopped a spinning wheel then the machine would tend to topple over in the direction of the wheel's spin (or conversely, topple in the opposite direction when spinning the wheel up).

After watching this video, my water cup never spilled on the corners

Exactly what I felt last month with you mate, even though I done rospa and got a gold… I find I still need to revisit the basics of advanced driving like cornering principles and our session was spot on, fingers crossed for the iam masters and also my adi training… again, many thanks for your excellent in car training, Alan

Excellent

As a Masters Mentor I also encourage this technique. However Reg, I'd like to hear you explain the difference between this teaching and track instruction which is generally to trail brake - that is, to brake into the bend, blending the brakes off as you blend the steering on. As well as generally being quicker on track, trail braking on the road means that if the bend tightens or an unexpected hazard comes into view you are already on the brakes - and can firm them up with no transition time and no upset to the balance of the car.

Class mate

Really useful

With front wheel drive cars, which most are today, I've always worked on the principal that each tyre has a finite amount of grip and if you ask it to divide the grip it has got between two demanding situations, cornering and braking, you're going to run out of it quicker so brake before the corner use all the grip to get round and off you go again. Slow in fast out.

Good advice but it's not a transfer of weight or indeed mass. As you say that's how it feels. So if it helps that people think it like that, no problem. It is however about balancing forces, acceleration v resistance and friction some of which is smoothed out by tyre compression and suspension work (synaptic feedback which correlates to that feeling of mass transferal) which is important to remember when hitting a rough patch and throttling when you need to come off completely. So as you enter a bend unless you are accelerating the car is decelerating and forces press down the front of the car increasing grip, as you round the bend rebalancing the speed to constant evens grip better to all tryres giving that lovely sense of control and stability, acceleration out of the bend reduces front grip permitting increased use of the castor effect to give the driver a pleasant exit out of the bend. In a modern car making adjustments for corners mostly all this will be psychological - slightly more pleasant - and the he car will even out the driver errors.

Nice vid, just one nitpick as a Professional Race Engineer (also ex emergency services blue light advanced driver)... Weight transfer would be incorrect and relates to another phenomenon in vehicle dynamics involving the change in a vehicles Ctr of Gravity. Load transfer would be the correct terminology because of the actions and reactions resulting in the chassis response specifically from acceleration and deceleration (loading amd unloading of the unsprung mass) that does not involve a change in the vehicles centre of gravity.

What about cornering in towns & cities (which as we know must be taken from around 05-20 mph) in second gear, turning right or left in town? If you apply acceleration before turning in at the low speeds required to make a turn off the road in a town centre and in second gear the power will not be available to hold the vehicle into the corner without driving it wide therefore entering a corners in town should presumably be done either on a trailing throttle in second or under acceleration using first. Comments please!

Nicely explained Reg. Slow in, fast out. Drivers (and riders) worry too much about over slowing. A few mph lost is soon regained. I wonder how long we will have to wait on this video for the 'trail braking' comments to appear?! 😯 I did one on why I generally don't but it's still flavour of the month/year on KZfaq.

This is a fault that every IAM instructor repeats when talking about/demonstrating this subject, and repeated again here. You demonstrate how unstable the car is by braking heavily into a corner, then demonstrate how stable a car is by accelerating lightly through the corner. If you are as delicate with the brake, hardly slowing the car at all, the same way you use the throttle, you will not upset the balance. And I’ll counter your three reasons with three reasons why this is better, Reg.1) Grip, as you mentioned (but discount by using a heavy braking scenario again), is increased on the front wheels, the ones that are doing the work. 2) Stopping, should something appear round the bend, will be quicker as the car is already in the right attitude to stop, no time will be taken by the car to shift weight from the rear and 3) your foot is already on the brake pedal so thinking time is reduced. Your way is easier to keep steady balance around the corner, granted. Folk are naturally much better at delicate use of the throttle than the brake, but you don’t seriously think that an F1 drive employing trail breaking at the limit of grip is unbalancing the car, do you? No, they have just learnt to use that pedal with finesse (a word I know you like).

11:43 has that biker been watching your videos?

Where can I get a camera pole, like one in the middle of the car?

Makes sense Reg, thanks. Sort of explains why its nice to have the 'confidence lift' before a corner, then back on the gas on the way through. What about downhill corners? I find these most difficult to get a comfortable balance, the car will often feel like it is accelerating just because of gravity, and more gas would just push the car wide.

Great video Reg with a good explanation of weight transfer and how you FEEL that transfer! One very small terminology gripe (because i'm a physicist 😎 ) mass does not move, it's the that weight does. ie these words should not be used interchangably Weight can simply be though of as where mass acts. The reason the cars body moves/tilts on the springs as you change speed or direction is because of the difference in where that weight acts with time, the ie weight transfer you so correctly explain about 🙂 One other thing i'd add is that on the road, (as opposed to on track) where you are not driving for ultimate performance, if you 'accelerate through the corner' technique is not just smoother, it's safer too. Under positive longitudinal acceleration, ie using the accelerator pedal to provide enough engine power to continually increase the speed of the vehicle as it travels through the bend, the front tyres are not actually operating at their maximum effectivess(grip) because you have removed some weight from them. That means should the corner tighten, or be more slippy than expected for some reason, if you lift off and stop accelerating, the front tyres are now able to provide more lateral ability, ie to tighten the cars cornering line. This is clearly preferable to arriving on the brakes with all the weight already transfered fowards, then the corner tightening or becoming slippy and finding you were already using all of the tyres capbility! In modern cars, especially large SUVs with big tyres that also have little or no steering feel which makes judgement of ultimate tyre grip rather difficult for a driver, this additional "safety net" really does help to prevent car / scenery interfaces... 👍👍👍

What happened with the M2 Reg?

I think it might be Newton's First Law rather than his Third that is relevant here.

So! 😊

Drive through the bend.

I am actually trying to apply this principle since more than 2 years and I still cannot do it right. Every time I approach a corner I am either faster than I should be or if my speed is correct and I try to press the gas as I am entering the corner, my speed is increasing more than it should and the car still feels a bit nervous. I keep trying, but I feel I need to slow down too much for the turn in order for this technique to work as expected. Do you have any advice? And also when going downhill, how should this be applied? Should I still be on the gas when going downhill? I think I will never get my speed correct that way.

How about cornering on a steep decent

This is for safe road driving right? What about trail braking? This is not the right technique for going as fast as possible on a track. “Balancing” the car to me is about having it on the limit of adhesion. This technique isn’t balance - it’s about stability in the dry. In the wet you may end up just understeering.

What about the fact that giving gas increases the grip requirement of the driven wheels? Is it negligible compared to the grip increase due to weight transfer?

I would like to see an episode where these AD techniques are applied while driving a Tesla Model 3 Dual Motor car. They’re heavier and weighted differently to cars with engines and handle differently.

What you wanna say???

0:04 you know you arent allowed to show german license plate's right? germany will sue

You’re actually on my favourite road. Did the drivers who brake all the way down the descents infuriate you? Something else to mention is warning the car what’s ahead by starting to load the car early. Loading the tyre blocks with the slightest of turns of the wheel, this then begins the process of a smooth load transfer. What I did notice was that you’re lengthening the corners. Good on road driving, again it smooths out the journey.

This is nothing new, I’ve been doing it for years. It’s common sense!

Vanishing point... Not limit point

My first thought..... Get your thumbs out of that wheel! It does not improve grip, does increase risk. Your braking/accelerating at the beginning is less a demonstration of the 3rd law of motion (action/reaction), but of the 1st law, things want continue as they were. Weight transfer is mostly about the 1st law, which could be simply summed up as momentum to the average person. The weight moves forward because it wants to keep going forward, momentum. I admit, I was only half watching after that, a phone call got in the way, did you cover one of the biggest problems for new drivers on country roads, the easy way to find a ditch or tree, lift-off oversteer?

Slow down.
