Very well presented! Yes, I was "drifting" in a sense, a long time before it became popular! I used to LOVE driving down wide, open country dirt roads... sort of "dukes of hazzard" style...Even in my very first couple of years of driving! And all of that "Playing around" made driving in icy and very wet conditions almost natural. I never became interested in real "Drifting" as a driving-sport. But I have many miles of experience in 'bad weather' driving, where my 'experience' paid big dividends.
Literally been struggling with the first corner of Lime Rock in the CTS-V, clicked on this video with the hope it gives me something that isn't obvious. But it's showing me a good line YAAAAY
"Understeer: you turn the steering wheel, you keep going straight, you hit a tree and die. Oversteer: you turn the steering wheel, the car turns around, you hit a tree and die. Oversteer is better beacuse you dont see the tree that killls you" -Richard hammond
Understeer= you hit the tree with your nose Oversteer= you hit the tree with your back So, understeer is better because you don't have to look at the tree that will kill you.
It's simple, really: Too much oversteer: stiffen the front end (ARB, springs, shocks) and/or soften the rear Too much understeer: soften the front and/or stiffen the rear. That's why you put stiffer rear ARB on a hothatch. For highspeed under/over, you also have to play with aero settings.
I know you meant that oversteer is faster when compared to understeer but I also know with the way you said it a few people are going to think you said oversteer is faster outright >< great videos though :D
Very good comment. I would like to give some extra input why oversteer is not faster. When the rear goes into a little slide, it means it has lost some or all of its grip. Also the grip that was needed to get the power to the road. This results in slower acceleration out of a corner. This is actually what drift drivers have mastered, and all drivers say the same: Drifting is not the fastest way around a track.
Maurice Wijma "When the rear goes into a little slide, it means it has lost some or all of its grip." Surely that's not entirely true. There is actually more grip to be had from sliding the tyres (front and/or rears) a little bit. The grip from the tyre increases up to a maximum at certain/optimal amount of slide/slip angle and then starts to decrease with further increases in slide/slip angle past the optimal point. If the car in question has extra power to take advantage of this additional grip from having a little slide/slip, then the car can carry more speed through the corner and/or accelerate out of the corner with a higher speed than if the tyres had no slide/slip angle at all. I think in order to achieve the required optimal slide/slip angle, the car cannot be understeery or else you won't be able to loosen the rear enough to achieve optimal slide/slip angle in the tyres. In that sense, it would be preferable to be oversteery vs understeering but neither are optimal and instead you'd want the car to be neutral to be fastest overall for the best turn in rate whilst maintaining highest possible grip and the ability to apply the throttle out of the corner without the rear snapping on you. Neutral being the perfect setup that allows easy, predictable driving behavior whilst still be able to closet to the/your limit, the limit having maximum speed due to having maximum grip from the tyres which comes from driving them at their optimal slide/slip angle. Drifting is going past the optimal slide/slip angle which decreases the grip vs zero slide/slip state and thus the corner must be driven slow than could otherwise be. Having said that though, i have wondered if there are exceptions to that rule based on the type of surface being driven on. E.g. gravel, snow, etc. Because I've read that ABS on gravel/snow is actually worse than just locking up the brakes of the car because if you lock them up on (sufficiently heavy) gravel/snow, the tyres will dig in and the gravel/snow will build up in front of the tyre slowing it down faster that if you tried braking without lockup. If that's so, then perhaps attacking a track's corner with heavy gravel/snow with a drift may allow you to attack it with the greatest speed possible for heavy gravel/snow. But I've digressed and perhaps i'm wrong.
DrR1pper i think what you're saying is right but what can make it confusing is when any rear slip is called oversteer, i think oversteer is only when the rear car is sliding out of control, if it is controlled and gets you around a corner faster I don't think oversteer is a good word for that situation because you arent OVERsteering you are steering exactly as intended and required to do so, there must be a better way of describing those situations.
megaspeed2v2 Right, think i see what you mean. So you take oversteer to just mean the tendency for the car to over rotate for some given input by the driver? But here's the thing. If you want to drive with as much speed through a corner as possible, you need as much grip as possible from all four tyres. To achieve the maximum grip from all four tyres simultaneously, each tyre must be driven at their optimal slide/slip angles. Provided the front and rear tyres have the same slide/slip angle to grip curves (which they usually do), then to achieve optimal grip from all four tyres you need all the tyres to point in the same direction whilst the car is holding an over-rotation of the optimal slide/slip angle to it's true direction of travel (i.e. it's actual trajectory vs it's forward facing direction). Since the rears are always pointing in the direction of the car, the front tyres need to face straight which means the steering angle needs to be straight during the cornering phase. But how can we do that? Surely, we need the car to have a slightly oversteery tendency, no? The opposite of oversteery is understeery which means the car will return to stability (straight and evenly distributed weight balance) when experiencing a perturbation (i.e. some weight shift, e.g. cornering). To get the most grip, you need to initially over-rotate the car with some steering input and then quickly return to center to stop the over-rotation and then maintain the rotation rate with a straight steering angle and using just the throttle and weight balance/shifting to steer it through the corner. Why? So all four tyres can remain at the optimal slide/slip angle. Edit: on second thoughts, i suppose one could argue that this is just a well balanced/neutrally setup car which just means it has some oversteery tendency in some areas of it's driving envelope and then some understeery tendencies elsewhere for stable, predictable handling. In which case, calling oversteery and understeery beneficial or a pain in the ass only makes real sense when talking about specifics? Blah! lol. Think i've blown this out of proportion. :P
Nice explanation. You briefly mention a "balanced car" at the end of the video. I assume that mean that all 4 wheels loose grip at about the same time?
so both understeer and oversteer do not give you as much directional change ac you could otherwise. even in oversteering your just rotating more but the velocity of your cars momentum is less affected as rapidly as the ideal in-between. so these concepts are all about losing control of momentum. thanks man
i understand how i wreaked my car now it was raining and i lost traction in the middle of a roundabout and the car oversteered tward the inside of the turn, so i instictively countersteered but i over corrected and whats more took my foot off the gas. the suddan deceleration was enough to cause a weight transfer to the front wheels while they were tuned too far to the left and a subsucant rapid return of traction, the car then shot to the left and right into the lane divider.
I know you said beginner level, but for understeer, Would you say the car leans away from the intended direction, do to weight transfer/ Inertia. The inside tire has less traction and therefore less power to pull you into the corner. You mention what to do to correct this at Beginner level, Counter steering for a split second should give you more traction to be able to continue in word into turn, right?
Here's weird thing. Understeer as described here simply requires the driver to oversteer, provided he has fwd or awd. With a good weight-balance it's possible to drift front and back simultaneously. With fwd, the fw's are oversteering and the rw's are sliding. This is very quick in corners.
Sean, I had hoped you would've talked more about what you should feel through the wheel with the situations. Even more than that I was expecting you to explain the reason behind why the feel happens, especially with oversteer. With oversteer you said that the tyres will automatically point in the opposite direction. Which is technically wrong. What happens is that the tyres have their self aligning torque that keeps them from twisting around their center axis. In other words, tyres don't want to turn but they like to roll straight ahead. The path of least resistance. What happens is that these tyres who wish to go straight are connect to the spindle behind it. Which has a spindle or steering arm to which your tie-rod is connected. This tie rod goes into a steering rack on both sides, left and right wheel. In the steering rack there is a bar, which is called the rack, that moves freely through the steering rack housing. So both tyres are connected directly to each other through the steering rack. On the rack there is a pinion, which is on the other end of the steering shaft to which your (in a real car) steering wheel is attached. This pinion is replaced by the FFB motor in a steering wheel for your computer/console. Now what happens with oversteer is dat the car rotates around the center point between your two front wheels. As the car rotates and the wheels keep wanting to go straight forward, the steering wheel automatically counter rotates as the rack is pushed through the steering rack house by the self aligning force of the front tyres. Which moves your pinion and thus the steering wheel. That is why in games and especially sims you should not need any faked seat of pants or weight transfer effects to know what the rear is doing. You already kan feel the push through the workings of the steering rack itself... if the tyre model and FFB model work correctly that is. If the tyres don't self align wel and don't stick wel to the asphalt in a correct manner, this will feel incorect in a game. Which is possibly a reason why with the simpler tyre models of the past we had to rely on fake weight transfer effects. An effect that is prone to oscillation as the car's weight, and especially fluids, don't stop suddenly when you hit wheel center on corner exit. Hopefully you can rely this info to your viewers, Sean. Knowing what you should feel and why you feel it is just as important as knowing the situation itself (i.e. what oversteer and understeer mean).
It is right to say that there is no car in its design where it tends to easily over or understeer but it is about how the driver drive it and when the car is being pushed to its limit then either condition will occur....
Well I drive a car with FWD, and one time when I entered a corner I didn't calculate for the accumulated speed that the car had made and I just turned the wheels rapidly, thus making the car lose grip, I sensed that right away and hit on the brakes as hard as I could, I stopped around 5 inches from hitting another car, I absolutely lost control of my car.
Thanks for the videos. Just getting into serious racing simulation. I actually have been through some higher level driving schools (law enforcement) There are some similarities, however racing is racing :P My struggles at the moment driving in the pack. I am racing truck series stuff mostly. I don't understand some of the concepts when you see guys pushing each other riding the draft (I do understand the clean air) but just generally driving with technique in the pack. I hope this make sense If not I can try and explain a little better. Just looking for technique to drive safer in the pack....and when I guy calls for help ( I try to be a freindly driver being a new guy) I know what he is talking about and can put myself and car in the position to provide meaningful help to another driver in the pack. Hope this makes sense! Look forward to the response.
6:00 the Wheels never should Point to the Oposite Direction. The Wheels should always Point to that Way you wanne go. Like here to see, when you pause the Screen at 6:01. The Wheels just Show in the Direction he wanne the Car to go.
Actually that is very true, when rally drivers wants to do a tight turn they just point their wheel where they want to go which by default the opposite where the rear end wants to go :D
turning the wheel where you want to go while it's in a spin doesn't help it. Turning the wheel the exact opposite of where the car is currently turning does. that's what he means.
How is counter-steer, counter intuitive? it's always seemed perfectly intuitive to me... Regardless; I'm starting to get the feeling that this guide might be a little TOO basic for anyone who is going to end up here in the first place.
He means that if you're turning right you would think you need to turn the wheel to the right but when you have that condition you need to turn the wheel left. I would think that would be fairly obvious to understand what he meant. Either you're just trying to be critical or you're pretty dim witted.
Big_Mike81 Apparently you don't understand the meaning of the word counterintuitive. If you are turning right, but the car turns too far right, the INTUITIVE thing to do, is to turn back the other way.
Kevin J. Dildonik even prior to my mechanical knowledge, I still INTUITIVELY understood the basic concept of countersteer (even if I didn't know what it was called) but I do agree that the final part of the recovery does become less intuitive to the uneducated (although in practice it is to some extent entirely intuition to get the timing right, I've had many a tank slapper in Sims, but very few in actual go-karts) BUT at this point we are well beyond the scope of this video which appears to be a VERY basic introduction to under/ oversteer. As for safety, yep! but to me I still find understeer terrifying, thankfully there is usually some sensation before it becomes a real issue (the main reason I drive with traction control off, day to day)
Usually when I oversteer and try to save it by countersteering nothing happens, just turn the wheels but still sliding in oversteer. Gotta counter steer faster? Something with the throttle control?
Throttle control, if you stay at the same speed, the momentum will send ur car side wards and content steering will do half the job, u need to slow down a bit or keep just touching the accelerator and leaving it continuously. Throttle control won't work alone neither will counter steering, they work together
Given that your car is FWD or AWD, your car is oversteering under control called drifting, and you can see that drifting would not be recovered by simply countersteering. You will have to countersteer and going on slight difference on the gas padel to basiclly recover easily. The reason that only countersteering will not work is that the car has inertia so it is much more difficult
Hey, We are designing a fuel efficient car for a competition during which our specification does not support the normal handling situation. However we need to go with the under steering or over steering one. We are in a dilemma to go with which one since our operating speed is about 30-40 km/hr and in a square like pitch? Viewing your video I think it is good to go with the oversteering than under steering one? Is it oK?
I assume you are in drifting state, not yet completely spin out. I'd say don't lift the throttle so early. Keep it up as it is in order to not deliver weight to the front suddenly which it make the situation more like pulling the hand brake: loosing little grip left at the rear tires by delivering the weight to the front tires suddenly. Just adjust the steering wheel to the direction car drifts and gradually decrease throttle/power. Too harsh maneuver could be resulted to opposite side sliding.
WHY DO YOU HOLD THE MODEL OF A CAR IN THE AIR AND SHAKE IT EXPLANING OVER/UNDERSTEER IF YOU HAVE BLACK SURFACE UNDERNEATH WHICH REPRESENTS THE TRACK????????????????
I don't think I understand how countersteering is counter-intuitive. If you turned right to enter the oversteer condition, it makes sense that you'd turn left to undo it.
+John Doe I think the point he was trying to make here is that some people may question why they are turning the wheel to the left when they are making a right turn.
Yes, it can. However, the main difference of fwd and rwd, is the fwd car needs to do two things simultaniously with the frontwheels...steer and put the power on the road. Also, it's nose heavy as it has the motor and drivetrain at the front. You can compare it a little to a dart arrow, which has what engineers call "directional stability"..so typically it would understeer. Another problem is it will "jerk" the steering if too much throttle is applied due to the way it's constructed, as mentioned before. Those facts are the reasons why high performance cars typical are rwd. They simply have a better handling, due to the weight distribution. On the flip side a fwd car is excellent in wet and snowy conditions...it has better traction to the driving wheels (more weight on them).
Yes and in some cases they can be more prone to oversteer during corner entry. Normal forces on a tire is what generates grip. Since all the weight is up front, snapping a fwd car into a turn will instantaneously load the front outer wheel. As the car experiences lateral acceleration, the front wheels generate more grip than the rear and can induce oversteer. Same occurs under heavy braking into a corner.
"not much you can do in a front wheel drive?" well you touched on weight distribution... but what about Scandinavian whip? The other methods? Sure it's not as fast as rear wheel drive... but it's not far behind, you just gotta throw it into the corner a bit more. You made it sound like "front wheel drive.... forget it, they don't work"
+Reuben Stern the scandinavian flick isnt exactly an efficient method compared to rwd oversteer lke you mentioned and if you have a long corner you cant really reflick. Fwd cars have to use a different set of boundaries on corner entry, kinda like how you would drive something with a heap of body roll vs something thats dragging its guts on the tarmac
+Stewart Mckinna also, you can tap the break to change the balance of a front wheel drive, so it will oversteer.... but obviously it's a lot slower. Like I said, he touched on it.
ease the throttle, you're kicking the ass end of the car and making the oversteer more aggressive, so throttle down, then when you get directional control begin to ease (emphasis on ease, don't jam it) the throttle up again
Oversteer with a rwd car can be very trick. If your oversteers the best to do is ease the throtle and corrects the trajectory with a bit countersteer, if necessary. But if you wants to keep the oversteer and slide you keep controling the throtle with very care. RWD cars have a tendence do spin doing this. Most if have central engine. When you accelerates the car weight is transfered to rear wheels, in rwd these are the wells that are tractioning the car and this cause a tendency to spin really quick. In FWD cars is more rare to oversteer. But it can happen. FWD cars tends to get stiff if you accelerate and countersteer. And you can't keep controling the oversteer(drifiting basicaly) in throtle because the car weight transfer do back wheels and the front whells lose traction. This things can vary a lot dependant on car weight distribution.
So understeer and oversteer in a system put in the car to get more traction on turns to stop the front or rear wheels from slipping even the slightest bit? That sounds really stupid and annoying.
+HighFiveGuy13 nope, they are not a system put in a car ... they are descriptors of a cars resulting handling characteristics quantified by all the cars systems, track conditions, and driver inputs.
Thanks man I've tried and tried but could never understand what these two ment. I've finally learned now thanks to you.
While I don't sim race anymore I still watch your videos and learn alot. Thanks for making The Simpit
Very well presented!
Yes, I was "drifting" in a sense, a long time before it became popular! I used to LOVE driving down wide, open country dirt roads... sort of "dukes of hazzard" style...Even in my very first couple of years of driving!

This was beautiful to watch. He explained in very simple and easy to understand words, using very good illustrations too.
Literally been struggling with the first corner of Lime Rock in the CTS-V, clicked on this video with the hope it gives me something that isn't obvious. But it's showing me a good line YAAAAY
Some men just wanna watch the world learn
I really struggle with the concept and science of this subject, but this helped me to visualize it and understand a bit more, thanks!
"Understeer: you turn the steering wheel, you keep going straight, you hit a tree and die.
Oversteer: you turn the steering wheel, the car turns around, you hit a tree and die.
Oversteer is better beacuse you dont see the tree that killls you"
-Richard hammond
Thank you… I have wanted to know this for a long time.. I understood the dynamics but not the terminology...
Top explanation! I race RC cars and I found this so helpful. Thanks!
Great charisma and enthusiasm, Shaun--love the video!
hey it's shaun. saw him in ISR's under 100$ rig build, awesome.
thanks for this. This finally allowed to drive a proper high HP RWD car in Project Cars
Awesome explanation Shaun, especially to the novice that's for sure,
Understeer= you hit the tree with your nose
Oversteer= you hit the tree with your back
So, understeer is better because you don't have to look at the tree that will kill you.
*oversteer* is best because you don't see the tree that kills you
Jesus has given you a gift thank you
Richard Hammond explained the same thing with toy cars in roughly 30 seconds.
very interesting video.Easy to understand to concept of under and over steering.
This is a fantastic instructional video - Thank You Simpit! =D
Very interesting and informative. Thanks for a very professional and entertaining presentation.
Can't wait for the setup videos. Bring them on please
It's simple, really:
Too much oversteer: stiffen the front end (ARB, springs, shocks) and/or soften the rear
Too much understeer: soften the front and/or stiffen the rear. That's why you put stiffer rear ARB on a hothatch.
For highspeed under/over, you also have to play with aero settings.
wicked video - sim racing forever!
I know you meant that oversteer is faster when compared to understeer but I also know with the way you said it a few people are going to think you said oversteer is faster outright >< great videos though :D
Very good comment. I would like to give some extra input why oversteer is not faster.
When the rear goes into a little slide, it means it has lost some or all of its grip. Also the grip that was needed to get the power to the road. This results in slower acceleration out of a corner.
This is actually what drift drivers have mastered, and all drivers say the same: Drifting is not the fastest way around a track.
Maurice Wijma "When the rear goes into a little slide, it means it has lost some or all of its grip."
Surely that's not entirely true. There is actually more grip to be had from sliding the tyres (front and/or rears) a little bit. The grip from the tyre increases up to a maximum at certain/optimal amount of slide/slip angle and then starts to decrease with further increases in slide/slip angle past the optimal point. If the car in question has extra power to take advantage of this additional grip from having a little slide/slip, then the car can carry more speed through the corner and/or accelerate out of the corner with a higher speed than if the tyres had no slide/slip angle at all.
I think in order to achieve the required optimal slide/slip angle, the car cannot be understeery or else you won't be able to loosen the rear enough to achieve optimal slide/slip angle in the tyres. In that sense, it would be preferable to be oversteery vs understeering but neither are optimal and instead you'd want the car to be neutral to be fastest overall for the best turn in rate whilst maintaining highest possible grip and the ability to apply the throttle out of the corner without the rear snapping on you. Neutral being the perfect setup that allows easy, predictable driving behavior whilst still be able to closet to the/your limit, the limit having maximum speed due to having maximum grip from the tyres which comes from driving them at their optimal slide/slip angle.
Drifting is going past the optimal slide/slip angle which decreases the grip vs zero slide/slip state and thus the corner must be driven slow than could otherwise be.

E.g. gravel, snow, etc. Because I've read that ABS on gravel/snow is actually worse than just locking up the brakes of the car because if you lock them up on (sufficiently heavy) gravel/snow, the tyres will dig in and the gravel/snow will build up in front of the tyre slowing it down faster that if you tried braking without lockup. If that's so, then perhaps attacking a track's corner with heavy gravel/snow with a drift may allow you to attack it with the greatest speed possible for heavy gravel/snow.
But I've digressed and perhaps i'm wrong.
DrR1pper i think what you're saying is right but what can make it confusing is when any rear slip is called oversteer, i think oversteer is only when the rear car is sliding out of control, if it is controlled and gets you around a corner faster I don't think oversteer is a good word for that situation because you arent OVERsteering you are steering exactly as intended and required to do so, there must be a better way of describing those situations.
megaspeed2v2 Right, think i see what you mean. So you take oversteer to just mean the tendency for the car to over rotate for some given input by the driver?

Since the rears are always pointing in the direction of the car, the front tyres need to face straight which means the steering angle needs to be straight during the cornering phase.
But how can we do that? Surely, we need the car to have a slightly oversteery tendency, no? The opposite of oversteery is understeery which means the car will return to stability (straight and evenly distributed weight balance) when experiencing a perturbation (i.e. some weight shift, e.g. cornering). To get the most grip, you need to initially over-rotate the car with some steering input and then quickly return to center to stop the over-rotation and then maintain the rotation rate with a straight steering angle and using just the throttle and weight balance/shifting to steer it through the corner. Why? So all four tyres can remain at the optimal slide/slip angle.
Edit: on second thoughts, i suppose one could argue that this is just a well balanced/neutrally setup car which just means it has some oversteery tendency in some areas of it's driving envelope and then some understeery tendencies elsewhere for stable, predictable handling. In which case, calling oversteery and understeery beneficial or a pain in the ass only makes real sense when talking about specifics?
Blah! lol. Think i've blown this out of proportion. :P
DrR1pper i tend to overblow things too xD its a complicated subject :D
Nice explanation. You briefly mention a "balanced car" at the end of the video. I assume that mean that all 4 wheels loose grip at about the same time?
GREAT explanation of the concepts...THANKS.
Technically, in the middle of a drift you are understeering.
HARD.
xD
Great video. I play F1 games and this will help me make the setup of the car. 😀
Nice job Shaun!
Nice video here man. Keep up the great work!

Great Explanation !! Nice Job
It is right to say that there is no car in its design where it tends to easily over or understeer but it is about how the driver drive it and when the car is being pushed to its limit then either condition will occur....
Can you do a video on how to over steer setups
For all us NASCAR guys loose=oversteer tight=understeer
Well I drive a car with FWD, and one time when I entered a corner I didn't calculate for the accumulated speed that the car had made and I just turned the wheels rapidly, thus making the car lose grip, I sensed that right away and hit on the brakes as hard as I could, I stopped around 5 inches from hitting another car, I absolutely lost control of my car.
Great video!
Sean when is Setup Shop coming? , I love tuning advice!
What if the car is AWD?? What tire pressure and camber would you put on it ?
This was an great video good job>>

Hope this makes sense! Look forward to the response.
Is that constant because i have went through understeering in a rwd car
6:00 the Wheels never should Point to the Oposite Direction.
The Wheels should always Point to that Way you wanne go.
Like here to see, when you pause the Screen at 6:01. The Wheels just Show in the Direction he wanne the Car to go.
Actually that is very true, when rally drivers wants to do a tight turn they just point their wheel where they want to go which by default the opposite where the rear end wants to go :D
turning the wheel where you want to go while it's in a spin doesn't help it. Turning the wheel the exact opposite of where the car is currently turning does. that's what he means.
amazing vid mate
great video thanks!
good explained
What's the first background song? searching for ages!
which simulator is that you are using?
hitting the gas harder to cure understeer works for rwd, not fwd, i think this should have been specified
How is counter-steer, counter intuitive? it's always seemed perfectly intuitive to me... Regardless; I'm starting to get the feeling that this guide might be a little TOO basic for anyone who is going to end up here in the first place.
He means that if you're turning right you would think you need to turn the wheel to the right but when you have that condition you need to turn the wheel left. I would think that would be fairly obvious to understand what he meant. Either you're just trying to be critical or you're pretty dim witted.
Big_Mike81 Apparently you don't understand the meaning of the word counterintuitive. If you are turning right, but the car turns too far right, the INTUITIVE thing to do, is to turn back the other way.
Kevin J. Dildonik even prior to my mechanical knowledge, I still INTUITIVELY understood the basic concept of countersteer (even if I didn't know what it was called)
but I do agree that the final part of the recovery does become less intuitive to the uneducated (although in practice it is to some extent entirely intuition to get the timing right, I've had many a tank slapper in Sims, but very few in actual go-karts)
BUT at this point we are well beyond the scope of this video which appears to be a VERY basic introduction to under/ oversteer.
As for safety, yep! but to me I still find understeer terrifying, thankfully there is usually some sensation before it becomes a real issue (the main reason I drive with traction control off, day to day)
I suggest you read the title of the video, it is what it is, lol.
GamingLegends There's a difference between a beginner, and someone who has gone for a ride with their dad for the first time.
THANK YOU FOR THIS VIDEO
Usually when I oversteer and try to save it by countersteering nothing happens, just turn the wheels but still sliding in oversteer.
Gotta counter steer faster? Something with the throttle control?
Throttle control, if you stay at the same speed, the momentum will send ur car side wards and content steering will do half the job, u need to slow down a bit or keep just touching the accelerator and leaving it continuously. Throttle control won't work alone neither will counter steering, they work together
Zameer Nizam Ahh of course! Thanks man. Will try this!
Given that your car is FWD or AWD, your car is oversteering under control called drifting, and you can see that drifting would not be recovered by simply countersteering. You will have to countersteer and going on slight difference on the gas padel to basiclly recover easily. The reason that only countersteering will not work is that the car has inertia so it is much more difficult
I like to oversteer on snow it is very fun ;)
Can you explain the technical arrangements required in car to drift
Aniket Punwatkar delicate right foot, and rear wheel drive with a fuck ton of power.
Hey, We are designing a fuel efficient car for a competition during which our specification does not support the normal handling situation. However we need to go with the under steering or over steering one. We are in a dilemma to go with which one since our operating speed is about 30-40 km/hr and in a square like pitch? Viewing your video I think it is good to go with the oversteering than under steering one? Is it oK?
If your speeds are less, oversteer is the best bet. However, the steering will be 'touchy'. Will need to control it more quickly
I have a doubt if i use too much of throttle in a corner n the back slips out shd i lift off the trottle or i shd use more throttle?
lift off the throttle
I assume you are in drifting state, not yet completely spin out.
I'd say don't lift the throttle so early.
Keep it up as it is in order to not deliver weight to the front suddenly which it make the situation more like pulling the hand brake: loosing little grip left at the rear tires by delivering the weight to the front tires suddenly.
Just adjust the steering wheel to the direction car drifts and gradually decrease throttle/power.
Too harsh maneuver could be resulted to opposite side sliding.
Ugur Akdag it depends a lot on the car and how gripy the front tires are
Of course, it depends many things actually.
This was very informative, thank you for the clarified explanation.
But...can you explain Snap Oversteer to me?
+blues03 Turning in and quickly lifting off throttle will cause an unsettling weight transfer.
SubaCoolAWD Ah, I see..cool. Thanks for the quick explanation.
Good. Thank you sir!
best xplanation
What game is that you use with a steering wheel?
He is playing iracing in this video but you can use a wheel with any racing game for the most part.
this was perfect.
WHY DO YOU HOLD THE MODEL OF A CAR IN THE AIR AND SHAKE IT EXPLANING OVER/UNDERSTEER IF YOU HAVE BLACK SURFACE UNDERNEATH WHICH REPRESENTS THE TRACK????????????????
I don't think I understand how countersteering is counter-intuitive. If you turned right to enter the oversteer condition, it makes sense that you'd turn left to undo it.
+John Doe I think the point he was trying to make here is that some people may question why they are turning the wheel to the left when they are making a right turn.
so does this mean fwd is understeer and rwd oversteer
or does it not matter
I guess technically both can but understeer is more prevalent in FWD than RWD due to the driving wheels being in different positions
Under Steering is Safe 'Won't Kill U'
Aftr Turning Accelerate. Not while Turning
Turning In = Braking
Mid Corner = Steering
Turning Out = Accelerate
Reduce Steering Lock = Increase Steering Response
y'all better put some respeck on that oversteer
yeah i'll put some "RESPECK" on oversteer xD
Eloquently put.
whats the music name
can a fwd car experience oversteer?
Yes, it can. However, the main difference of fwd and rwd, is the fwd car needs to do two things simultaniously with the frontwheels...steer and put the power on the road. Also, it's nose heavy as it has the motor and drivetrain at the front. You can compare it a little to a dart arrow, which has what engineers call "directional stability"..so typically it would understeer. Another problem is it will "jerk" the steering if too much throttle is applied due to the way it's constructed, as mentioned before. Those facts are the reasons why high performance cars typical are rwd. They simply have a better handling, due to the weight distribution. On the flip side a fwd car is excellent in wet and snowy conditions...it has better traction to the driving wheels (more weight on them).
Kalle Klæp thanks dude😄
My car (2002 Civic Si) does oversteer if you lift off the gas just after the front starts to slide.
Yes and in some cases they can be more prone to oversteer during corner entry. Normal forces on a tire is what generates grip. Since all the weight is up front, snapping a fwd car into a turn will instantaneously load the front outer wheel. As the car experiences lateral acceleration, the front wheels generate more grip than the rear and can induce oversteer. Same occurs under heavy braking into a corner.
Tyler Scrivner oh that makes sense. Thanks 😆
"not much you can do in a front wheel drive?" well you touched on weight distribution... but what about Scandinavian whip? The other methods? Sure it's not as fast as rear wheel drive... but it's not far behind, you just gotta throw it into the corner a bit more. You made it sound like "front wheel drive.... forget it, they don't work"
+Reuben Stern the scandinavian flick isnt exactly an efficient method compared to rwd oversteer lke you mentioned and if you have a long corner you cant really reflick. Fwd cars have to use a different set of boundaries on corner entry, kinda like how you would drive something with a heap of body roll vs something thats dragging its guts on the tarmac
+Stewart Mckinna also, you can tap the break to change the balance of a front wheel drive, so it will oversteer.... but obviously it's a lot slower. Like I said, he touched on it.
What to do when a car oversteer due to more throttle
ease the throttle, you're kicking the ass end of the car and making the oversteer more aggressive, so throttle down, then when you get directional control begin to ease (emphasis on ease, don't jam it) the throttle up again
For rwd or fwd?
Oversteer with a rwd car can be very trick. If your oversteers the best to do is ease the throtle and corrects the trajectory with a bit countersteer, if necessary.
But if you wants to keep the oversteer and slide you keep controling the throtle with very care. RWD cars have a tendence do spin doing this. Most if have central engine. When you accelerates the car weight is transfered to rear wheels, in rwd these are the wells that are tractioning the car and this cause a tendency to spin really quick.
In FWD cars is more rare to oversteer. But it can happen. FWD cars tends to get stiff if you accelerate and countersteer. And you can't keep controling the oversteer(drifiting basicaly) in throtle because the car weight transfer do back wheels and the front whells lose traction.
This things can vary a lot dependant on car weight distribution.
wrong , fwd cars cant drift cuz you cant keep your rear tires spinning
+Miguel M Silva Fwd cars can drift. They can't keep the drifting. But it's possible to enter curves powersliding and do small short drifts.
Shaun, I miss you! What happened; are you okay?
So understeer and oversteer in a system put in the car to get more traction on turns to stop the front or rear wheels from slipping even the slightest bit? That sounds really stupid and annoying.
+HighFiveGuy13 nope, they are not a system put in a car ... they are descriptors of a cars resulting handling characteristics quantified by all the cars systems, track conditions, and driver inputs.
Top Gear covers this in 23 seconds...
logo os SP reminds me to a league of legends team, TSM
im used to oversteer lol, i cant bare understeer
In my experience in a Ford gt in gran turismo the oversteer is unbearable
Its not understeer or oversteer, its you taking the corner faster than you're supposed to

Looks like the TSM logo lol
Isn't drift understeer? That's what I've been told
nope
Using Charlotte Motor Speedway isn't gonna help :P
So in between understeer and oversteer..........THat is called Drifting
Nah, really hard understeer after a large amount of oversteer, that's a drift.
Just drift it
Nah just rip the e brake and pray
So many careers that should be abandoned... keep it in the video game world

oversteer is better coz you don't see the tree that kills you
