Must've been hard to do a front end alignment on a horse.

Adjusting Ackerman is one of the most underrated setup changes on karts as well

This is exactly why I love this channel, I learn things that I never imagined existed! Thank you!

I loved your overhead simulator example, it really cleared it up

as far as I understand, Anti-Ackerman actually REDUCES tire-wear on the inside tire because the outside tire is driving with a certain amount of slip angle and therefore the inside tire is actually not scrubbing over the tarmac at all. The normal Ackermann behaviour would lead to massive amounts of scrubbing, because the outside tire does all of the work and the inside tire would just understeer

Established Titles is a SCAM! Be careful when accepting sponsors!

short answer: to maximize the slip angle effectiveness for each tyre

RIP to that Established Titles sponsorship😅

Established titles is a scam. You should look them up further and not support a scam company.

I have Anti Akerman setup from factory on my Giulia Quadrifoglio. This is a great video explaining why it’s used as it is and how it works. At low speed on cold tyres and high steering input you can fee the front end skipping

The way I understand it for a track car set-up is for keeping the proper wheel track while pushing the limits. The outside wheel under load will pull out while the inside with little load will actually end up turning in more. So when not under load it looks weird with outside turning more but under race load it tracks correctly.

I just noticed recently that Driver61's video about Alonso's bizarre steering technique was taken down. It's such a shame, I would love to rewatch that video after watching this video.

I like it for a long wheelbase, heavier front end truck, as well. It's already "pointy" in front. Improve the outer wheel for weight transfer and stability in the turn. Along with better weight balance throughout the truck/SUV, and you get better handling. Especially with plus-tires that handle more weight/ load; go the sway bar, coilover, equalized setup route, and it's hanging with sedans, anywhere.

You explained it in such a great manner, thank you for this beautiful video!

Kudos to Scott for having an advert timer bar just like donut so you know just were to skip too 🙌

There's also a significant aerodynamic reason for the F1 teams to run anti-ackerman; a shallower angle of attack on the inside wheel means that the wheel wake of the inside wheel is not sent as far inboard, thereby wreaking less havoc aerodynamically downstream.

There are SO many details in an F1 car and this is another one you explained beautifully. Keep up the great job!

Even go-karts steering is like this.

Great video! Would be great to know how velocity affects the graph. And after all, that reminds me of go karts, where steering is quite mainly on the outer wheel, as usually the inside one in a turn is quite unloaded, due to steering geometry(it lifts, when you rotate the steering,). Keep up the great work!!

Ive always wondered why this was. Super helpful thank you!

Scott, would you be able to do a feature on the 2026 F1 power unit rules? They seem to be pushing the cars into more lit-and-coast and burning fuel to generate electricity, possibly making the racing worse.

Thanks for this insight, We know that's there is far more than what just the commentators talk about there's so much that goes into the setup for each track for each driver but it's good to see it's a different subject thank you

What about Casper Ackerman

Sorry but I think you missed the key reason. The reason stays in the graph 5:53 “Line of peaks” Before load transfer, assuming 6000N on each side, and after 2000 of load transfer, outer wheel can accept more steering angle while inner wheel needs less steering angle to keep maximum. I can’t agree that F1 cars use anti-ackerman because they rely on outside tire. They do on both tires, trying to maximize total grip.(anti ackerman offers the peak grip by finding optimum slide angle on each tires)

This is not only a great video for F1 but for automotive physics as a whole as well. The charts are also super helpful, thank you!

Great content and subject man, never knew this - Thanks 🙏

Ackerman steering was a question thrown at me during an interview for a university place. No idea what it was at the time, especially since the place I was going for was computer studies. I failed. But my major car concern right then was all the water leaking out of the radiator on my journey over. My first car, a 1959 Ford 100E, reg no 2668 CR. Would love to have you back.

It is awesome to find who make this sport and it's technology understandable. Magnificent work bro. All the best 👍🏻.

Fantastic content Scott! 👌

I was waiting for a clip of Alonso at Renault (2005-2006), back when he was actively inducing understeer in order to turn...

I absolutely love this channel, very well done!

I have made anti-ackerman geometry in my team FORMULA STUDENT car we will see how it will perform

been watching your channel for a while.. this is the best to show my students on how a car works,,,,a few will drop out of class.. they just want'a'be a racer bmw driver.. the ones that stay are the best students.. they dont race on the road,, and they always tell me about there driving exp.. how the car handled with this or that.. the ones that dropped out.. well thru the grapevine.. they get lots of tickets,, and a few have wrecked there( or daddys ) car,,,great channel,,keep it going

For dirt racing, I adjusted the Ackerman to work in reverse, so the wheels pointed the right way when the car went sideways. Edit: I split the cross steering arm in the middle and had adjustment holes in a pivoting 'spade' arrangement.

What a video. Congrats guys. More of this pls

The white line simulation reminds me of Andy Green and Thrust SSC/Bloodhound LSR going over 600MPH. I wonder what they used on the Ackerman angles. I wish I had asked Richard Noble this when I met him!

Another legendary video 💯 Thanks for the breakdown 🙏

Great job as always thanks :)

All this my friends depends from slip angle of your tire

Almost the same concept of how you turn on the outside ski when carving. This is very important in GS racing.

Woah, this is really amazing, never thought of it in this way !!

Always wondered. Thank you

I'm F1 fan for over 20 years now and never heard of this, thanks for the lesson!

How is the anti-Ackerman steering accomplished mechanically?

It would be nice to have a follow up video explaining how the teams mechanically adjust it from track to track 🙌

I've been asking this for years..... thanks for explaining.

Hey! I think you have the best explanation of understeer (and potentially oversteer)/slip angle I've seen yet! A layman (regarding car/racing knowledge) can understand the concept of the wheel being pointed farther than the real steering direction with this explanation. Might you do a stand-alone video explaining this? It would be a useful resource for explaining the concept

Fascinating. Great example of why this channel adds value to the ecosystem!

Ackerman angles! i don't know much about it but I can thank assoluto racing for teaching me what it is

Now that established titles is a scam, you need to re-upload this without the ad.

Fantastic content.... Very instructive

For road or other than F1 cars with FrWD or FWD front tires not only steer, but also drive, and use of front differentials enhances this even more, so different principles apply to steering

You can create a car setup for each circuit and save them to custom configs. If the steering wheel doesn't work then you have to go into settings and activate the wheel animations in player setup.

Brilliant! thank you.

Amazing! I had no idea how F1 cars steer... often vaguely wondering about that very question. Lankensperger steering. Thanks!

I never knew this. Thanks

I feel like this is the kind of topic which requires a longer video and some in-situation examples. It's fascinating but a crash course is way too short for this 😥. Thanks though I learned something interesting today !

Awesome! Learning something every day

i learned something new today. thanks driver61.

I totally never knew this. Learned so much.

so in general anti-akerman used to reduce outside wheel slip angle because its contribute more then inside wheel on cornering on F1 speeds and to have overal slip angle less to lessen chanses to lose a grip?

01:45 It looks like some dope machinery. Instead of Pirelli it had wood. And 1 wheel in front (for steering) and 1 in the back. It really needed to turn fast. Especially when carried in hand. Amazing! 👍 The steering wheel looks badass! Without LED.

🤯 thank you. Must to know for everybody!

Adding a time bar to your ads? Simple but nice addition. Also I learned a lot in this video

Tune to win by Caroll Smith has it all, and maybe the graph shown of slip angle vs lateral force isn't really of a slick tyre, it's more representative of a passenger car tyre.

I thought the reduced slip angle on the unweighted (or lesser weighted) is inside tyre was to increase its contribution to cornering force because it is in the performance window where the turning angle brings the tyre into a slip angle where it can contribute to lateral force, instead of just scrubbing off speed, though some scrubbing can help to rotate the car. To help the inside tyre do this, suspension geometry can be set to reduce the camber on the inside tyre so the contact patch is bigger. The contact patch of the outside tyre is increased by the vertical load and tyre deformation so increased camber stops the inside of the tyre from lifting

As a skier who learned backcountry, I taught at Vail one year and they teach anti-Ackerman but it’s slower and I set the staff daily vertical feet record for the season one year skiing Ackerman wedge down backbowl pitches

very very good video and explantion, the sim is what did it for me:)

Hey @Driver61 could you maybe do a video on F1 running 4 cylinder engines. I know that might not be everyone's cup of tea and the chances of running v10's 12's or even 8's being so slim, if you look at how powerful bmw's 4 cylinder f1 engine was that brabham and Benetton used and how successful the Japan Super Formula series is with their 4 cylinders I'm sure F1 could make a success out of it. Sure the engines that is used in the Japan Super Formula series doesn't rev as high as F1 today but in my opinion they sound better. With the planned removal of the mgu-h and an inline 4 cylinder being slimmer than a V6 it could possibly mean slimmer and shorter as well as lighter cars. The Japan Super Formula cars weigh only 660kg with the driver included. Also manufacturers like Mercedes, Redbull with Honda and Renault for Alpine all have big experience and great success with 4 cylinders, I'm not sure of Ferrari but even the new comer Audi or at least VW has experience and success with 4 cylinders so that would mean no team would have a major advantage by being more experienced with those engines and it would be something fresh for F1. Also there were talks of increasing the power output of the mgu-k so with a 2l turbo 4 cylinder engine that makes about 600hp (not impossible the super gt cars make 600- 650hp and uses the same engine as the super formula) with the mgu-k you could be looking at 800 - 900hp in total.

Very interesting, thank you

For some reason i enjoy listening to ur voice

Fantastic video 👍

I think this video really would have benefited from a simple top-down animation of the starring assembly geometry, with lines to indicate the forward direction of the tires. I think the concept is easier to grasp when you realize that even with a positive or negative Ackerman geometry the tires do remain straight when the steering is neutral, and the difference in the angles only occurs in the geometry when steering.

Wow can't believe they're talking about this now we understood this in the 80's when I was karting Kali karts didn't use Ackerman

@driver61 the orange bar at the bottom of your videos is the best thing on KZfaq. We the viewers really appreciate it! Thanks.

Wow this is nerdy! I love it!

Yup I always test the car Ackerman when I first drive it. Just to get the feeling. Personally I love some anti Ackerman, but that's just a personal preference

Everyone knows that Established Titles thing is a scam, right? Shame to see it promoted here.

07:00 with more load the optimum slip angle is higher so the grip for the inner wheel should be higher than with a street setup

I would like for you to analyze Fernando Alonso's driving style ( well, prior to 2022 ) with respect to slip angle, and how he had the team setup his car. As I recall, he used to put a LOT of steering input on corner entry, almost a "jab" or "excessive turn input" for a brief moment as if to put heat into the fronts.

Book recommendations for engineers : Race car dynamics (Millikan&M) Tune to win (Carroll smith)

I used anti-acreman in the original Xbox Forza. Didn't know what it was but left out the lap with a draft of 4 car's. I was in the games 3rd fastest car a Jag XJ 220 the rest in Enzo's. We set the 1st 2nd 3rd and 6th fastest all-time times at the test track 5 mile Oval. Yeah I got passed at the line but that's how close it was at 325 MPH.

When going around a corner the outside wheels travel a further distance. Hence since the car goes around it at the same speed i all places the outside wheels need to turn faster. Iirc thats why the are Differentials in road cars.

After 1 minute THIS earned you a SUB!

Doesn't the inside tire actually experience less wear with anti-ackerman? So the outside tire takes all of the load and the inside is preserved, according to the load distribution in a corner. Could we say that parallel steering in a fast race car (tires at load limit) would already be an improvement over positive ackerman for the same reasons?

Are you referring centripetal force as lateral force

Please can you guys make a video on the super license?

Oof, hopefully Driver61 wont be accepting Established Titles sponsorships in the future with all the evidence coming out of Established Titles being a scam.

At first, i though it's just an angle of the camera, I didn't know it's an innovation

we need more games to impliment ackerman in the tuning as I have seen some roblox racing games impliment ackerman while a AAA game like forza doesnt

I'm not sure it would ruin tyres quickly on a road car. Going from positive to negative and back just means you're choosing which tyre slips. For F1 keeping temps more even is more useful. On the road a better balance of grip at lower lateral load is preferable. I would love to see a test on how it feels to drive and how the tyres wear when compared - maybe one for the other channel? Not sure what cheap road car you can find which would be easy enough to change it though?

not only, Anti Ackermann gives more stability in fast corners

I figured it was down to slip angle. The overhead sim footage was cool

yeah, but is this also true for other series? like DTM, WEC, former WTCC etc...

What steering do lmp or touring cars use?

Would a track 2022 brz running 200tw tires or around a ps4s tire. See a benefit running say in grid life with something like this. Or is this against some rule? Or is it the track width? Is it aero limited? Power limited? So many more questions now.

5:14 that hás to be a Nickelback meme reference.

Great video! Established titles a scam though

One simple statement or thought was missing at the summary. The inner tire has decreased slip angle allowing it to not saturate the curves and still contribute as much as possible to the turning of the f1 car. The decreased load and slip angle combine to lower the maximum slip angle of the inner wheel.

We need Checo/Verstappen /Brazil/Monaco analysis! Thank you.
