Lamborghini’s NEW Active Alignment is Revolutionary!

Lamborghini Reinvents... The Wheel Hub?!
This prototype technology shaves seconds off a lap by adjusting alignment settings like toe and camber up to 60 times a second. It's similar to Mercedes' Formula 1 dual-axis steering, but a lot more advanced. How does Lamborghini's Active Wheel Carrier work, and when can you get your hands on it? Watch to find out!

[@brianb-p6586]

Changing toe at the hubs is no different from changing steering angle with the tie rod, so for steer-by-wire installations this doesn't require any hardware in the hub, just separate left and right actuators. Some cars already do this, using hardware from ZF and perhaps others, mostly for packaging reasons. Changing camber can also be done with suspension links. This is most practical for single links, but some multi-link suspension designs do have a single upper lateral link per side. Force on this link will be high compared to a steering tie rod, so a high-force short-travel actuator would be required.

[@wakimaniac]

This should have been uploaded on driver 61

[@Ben-Rogue]

To me, it'd make more sense to have a system mounted inboard and acting on the lower a-arms, as this could easily perform the task of adjusting camber and toe as well as rear steering, and it'd not require additional unsprung mass and engineering it to withstand the extra stress

[@salt-emoji]

Gl to Will and Callum. They'll do well.

Road cars do have a slight toe-in and caster angle at the front, this makes the steering wheel return to neutral position after cornering.

No… most road cars call for zero toe at the front. The caster helps on-center feel.

I am not surprised by the introduction of that tech, what i am most surprised with is the fact that it's actually Lamborghini who came up with a working idea. Usually when it comes to mechanical engineering it's Audi or Porsche who come up with a revolutionary technology. Granted they are all under the same roof of VW, but it's nice to see that there is some different areas of innovation being worked at by the different brands at VAG.

[@JH-jo9wt]

It'll be German my guess ZF sachs like rear wheel steering

[@jamesderbyshire703]

You don't have to do it at the hub, you could do the adjustments at the suspension pick ups on the chassis. Pretty sure you could move your lower or upper wishbones in and out to adjust camber. It will affect Toe so naturally you have to be able to adjust that as well. The adjustments to the steering arm are a little bit more complex but if you already running drive by wire and had 2 steering box/racks you could control each individually to adjust toe on the fly. Ackermann's angle means very little with this setup so you can choose a low drag setup or a high angle setup to try pump heat into the tyre. I can see how it makes several seconds a lap difference!

[@gotindrachenhart]

Just do away with arms and use nothing but links :)

[@wingracer1614]

Yes but now you have multiple actuators each doing a single thing. That's rather heavy, takes up a lot of space and is just plain inelegant. This is a very small, single component that can do it all.

Completly agree motorised tie rods would even enable to change the front alignments on the fly at a very low cost in dollars and unsuspended weight, maybe i should work for Lambo ;-)

[@ericmichel3857]

@@wingracer1614 I disagree, having that mechanism in the hub adds unsprung weight which is bad for performance. Also the hub is exposed to a lot more force and heat meaning it has to be heavy duty and still will be more prone to failure. So while yes you would need two actuators per wheel instead of one, they can be much smaller, simple, and would add virtually nothing to unsprung weight. In this regard it is the far more elegant and reliable solution. Even from a service perspective, when your hub bearings need replacement do you want to buy and replace this monster dynamic hub assembly, as opposed to maybe a single rod actuator (assuming one ever went bad). A well engineered rod actuator could easily last the life of the car however, with hub bearings it's not so much a matter of if you will need to replace your hub bearings, it's more a matter of when (especially for cars the see track duty).

Oh wow, memory unlocked, i remember being 12 or so and experimenting the toe and camber of my Baja 5b. I had no idea what i was doing but really noticed the differences.

[@AMS-KungPao]

Usually starts out that way, especially if your self taught. You just mess around with settings not knowing how they'll effect the car's driving but as you keep doing it over the years you'll notice these consistencies and patterns and before you know it you have an intimate understanding of how everything works through experience if you keep doing it.

[@TriCountyMotorsEastman]

Most street cars have slight toe-in when aligned. It is very slight usually something like 1/32 of an inch. That helps the car track straight

[@ICKY427]

holy crap 3 seconds a lap is MASSIVE especially considering they only had them on the rear end of the car. one thing yall didnt touch one was the benefits to straight line braking and accel. normally you'd have a good couple degrees of front camber, and under braking it goes even further as the front of the car dives. thats a huge comprimise for braking grip. but this could dial a bit of positive front camber under braking (and a little negative in the rear) to keep all 4 tires flat and giving incredible braking capability. the issues they have with implementing this on the front end could easily be solved by motorizing the upper control arms for camber control. (honestly, they could do that with the rear UCA and a rear toe link as well, then they wouldnt have to worry about the parts experiencing so much shock from bumps.)

[@Leshic2]

After driving a car at 10/10th on the track with technology that turns the rear wheels to "help you go faster", I found the technology counter-productive... It reminds me of when F1 engineers come up with new technology to "make the car faster", but the driver now has to change their driving style to compliment the new technology... Imagine, you turn by X degrees, expecting ABC resulting behavior. However, the car turns turns X+2, or X-1, and gives you EFG behavior.... You, as a driver, feel EFG behavior, counter, to return to ABC behavior, but now with an ABC(offset) driving line.. The car constantly adjusts to your input to give a different expected behavior... You're always "fighting" the computer and electronics, to fool it to get it to do what you want... The servos that make these adjustments, would need to be fast when you turn the steering wheel fast, but slow when you're slow, and intelligent enough to not make things worse.. Add to that.... the behavior of those servos and sensors, is the same in extreme heat, verse colder temps... .. the behavior is the same on lap 1 as on lap 20 or lap 50... .. as well as at 1,000 miles, verses 30,000 miles, 60,000 miles, because things naturally wear out... ... rain and dry.. I predict, Version 1, will be terrible, and by Version 3, or 4, it will be fantastic... Maybe Lamborghini is the beta, test bed for future Porsche technology?

[@AMS-KungPao]

@@Leshic2 Changing your driving style to accommodate for a car that drives better than it used to takes very little time for a F1 driver, not even 10 minutes so this isn't a big deal at all. If a F1 driver can't change their lines or braking points a little bit to get used to what is basically a new car then idk how they got into F1 in the first place since that's what they have to do every year anyways, especially when a new era of F1 cars get launched. F1 drivers have to change their driving style all the time throughout the season as well through upgrades the manufacturers make to the car so the fact that it theoretically could be a problem if in F1 because F1 drivers have to change their driving style (because it is technology that "makes the car go faster") is nonsense. Now, when it comes to the car all of a sudden experiencing loads of new understeer/oversteer that it didn't before, then there's an issue because then you'd have to make much more significant changes to how a person drives but this isn't the case with this technology since the technology gets rid of unwanted understeer/oversteer. If you feel like you're constantly "fighting" with the car when it drives better than it did and it also drove pretty well previously, then you're not a good driver and probably need to get better of you don't want to possibly put other people on the road around you in danger. If your driving is that bad than you need help (not saying it is btw but just anybody in general).

i could see it actually hit road cars via arms. like a little motor on toe and camber arms. not too different than rear steer on cars. that way its not 100% of the load and if one breaks its less exspensive. like they could make the camber arm way more beafy due to it being the one that takes the most hits from the road compared to the toe arm.

For road cars it would make sense to move that system to the upper and or lower suspension control arms, so that the system is better protected against jolts and vibration. The effect might be somewhat limited by moving the system, but then on the road you wouldn't need that much of a variation in alignment to improve the handling.

Brilliant idea, I can easily see the potential performance advantages but guessing that a long-term reliable and cost effective solution will remain elusive. If only I could DIY it to my Miata or Lotus!

[@5150Failure]

it could be modded into other cars. espesially multilink cars that have indipendent camber and toe allignment settings. think about the 4wheel steer in the back. to adjust toe all you would need is a little motor to pull and push an arm. that can be translated to camber to. twin wish bone style would be alot more difficult but might last longer or atleast if it fails wont cause the car to just loose a wheel. like the lambo one if it fails it could just break the hub clean off not good. but on a twin wish bone it could just act like you have no bushing in the arm which would suck if it happned in track or back roads. but it would be able to be limped to a safe spot and or home. i now am thinking how how to get something like this in my NA in a safe way.

These things must be a LOT heaver than normal hubs, in a place where weight is super important. I suppose you could at least partially mitigate the increased unsprung weight by mounting the springs and dampers inboard, with pushrods.

[@wingracer1614]

All else being equal, pushrods INCREASE unsprung mass, not reduce it. You still have to move the mass of the pushrod

[@zounds13]

@@wingracer1614 No. There's no frickin way a pushrod outboard of a chassis-mounted rocker weighs more than an inboard coilover spring/shock. Hell, the spring alone would outweigh the pushrod. The inboard-mounted coilover in a pushrod suspension is SPRUNG weight.

[@wingracer1614]

@@zounds13 Stop talking about weight, it's MASS we are talking about. Mass has inertia. With a conventional coilover on the arm, any forces trying to move the suspension have to move the mass of the shock shaft, associated mounting hardware, half the mass of the spring and the lower spring perch. Move it inboard with a pushrod, all of that stuff still has to moved PLUS the mass of the pushrod and the bellcrank. You also need to realize, not all of the mass of a coilover is unsprung. Only the parts that move with the control arm are unsprung, the parts that move with the body are sprung mass.

[@zounds13]

@@wingracer1614 okay then, let’s talk mass. UNSPRUNG mass, not total mass, is the big bad thing that chassis engineers always try so hard to minimize. Coilovers are heavy. Even if you don’t count the bits that would be sprung mass in a conventional setup (and you’re right, we shouldn’t), what’s left is still significantly heavier (excuse me, “masses more”) than a well-designed rod and crank. Removing that mass from the unsprung total can only be beneficial. Yes, with the addition of the rod and crank, the total mass of the suspension is higher, but the total UNSPRUNG mass (or “weight,” for the less pedantic among us) is lower. You need to understand that low mass isn’t always the most important consideration. Wide wheels and tires have a lot more mass than narrow ones (rotational mass at that), but the increased traction they provide usually more than offsets the mass penalty. Or are you now going to try to tell us that it’s always better to use narrow wheels and tires because they have less mass?

[@wingracer1614]

@@zounds13 But a pushrod system doesn't just have the mass of the pushrod and crank to move. It still has to move the shock shaft, piston, half the mass of the spring, lower spring perch, etc. Just because it is no longer in line with gravity doesn't mean it's not being moved as unsprung mass. Yeah from a gravity standpoint, it is now sprung weight but the mass of all those components still has to be moved and THAT is what matters. The reason designers care about "unsprung weight" is because all that mass has inertia. That inertia resists the tire's ability to travel up to absorb a bump and also resists the tire's ability to go back down, causing it to over travel over the bump. ANYTHING attached to that tire/suspension with mass is going to increase that problem It doesn't matter if it's vertical attached to the arm or horizontal with a pushrod, it still has to move and it still has mass Your last point is totally agreeing with my original point that the gains from this system should FAR outweigh the slight losses from increased unsprung mass.

SW20 MR2 and 4th Gen preludes had dynamic rear toe. By weight transfering you change the toe to yaw faster.

[@Dqtube]

1:29 This must be a quote from the HAAS technical manual. The whole of last season they focused entirely on lap times and not tyre life.

[@gerryjamesedwards1227]

It'll be interesting to drive one when the system inevitably freaks out and gives all the wheels max toe in. Someone will also figure out how to tweak the camber settings to max them out.... for durrrrrr-ifting!

[@JohnCharb87]

Back to the classic basics. Like when it was Driven Media.

[@pbocking44]

Maybe useful to keep a small %tage of grip in reserve - to be added in when car is beginning to skid. To make a car more forgiving. Easier to drive at the limit.

[@tomast9034]

there is toe in on the road cars...thats putting some tension in all elements of the streeing so it doesnt rattle around on its own if there is some wear. always pushing the front wheels inward to the cars axis no matter what.

[@pjsw]

Sorrry but this aint it. I also refuse to believe that a youtube channel getting constistent views above 100k and averaging around 250-300k wasnt profitable especially with sponsorship segments. Even with expensive to produce videos you could have looked at making similar content cheaper.

You ruined your videos getting rid of the good stuff and wasting money on the stupid go kart upside down project. Yawn.

[@procprime]

This ain’t it, this isn’t what (at least some) people want to see. I don’t think it was worth ruining everything just for the silly idea of driving a car upside down sometime, which might not even happen.

[@BIGGELATO]

Love it when technology is used to help us be more efficient. No drama crap like giving control to AI. Just simply, tech helping people be better.

[@MidgetBarmaid]

A few time attack cars have electronic dampening and the engineers are able to set up the suspension corner by corner via GPS coordinates. I was chatting to one of the engineers and was blown away and the idea of try to turn a car for every corner of a track and the fact a driver has to give feed back on a dynamic car. Super cool though.

Neat tech, just gotta wonder about longterm reliability and maintenance procedures for this

[@SapioiT]

Changing the toe can have the advantage of much tighter parallel parking. Just back-and-forth the car while it's zigzagging to a side, without moving the steering wheel. Maybe even make cars which have a driveshaft connection on the back, like tractors, and a button to engage or disengage another gear which to connect the reverse gear and the forwards first gear to the tractor-like connection, so another wheel can be used to park into or get out of tight parking spaces. And pickups in particular but really all cars in general could make use of such a connection (even with only a finger-powered clutch and lever for acceleration level which can be locked in place) to power other devices. For example, a power generator for a house which to have a similar connection so you can use fuel from the vehicle instead of from the generator, so you can have the generator use one type of fuel and when you run out of it you can generate power with the car, or normal tractor attachments (i.e. water pump, cutters, tillers, etc.), or even new attachments, like a chain system which to cause a portable house to either pack up or deploy by having parts of the structure slide in/out and/or fold in/out. You know, like those houses which are delivered folded and you only have to unfold them and use a few screws, but with a mechanism using springs and magnets which require you to use more force to pack it or deploy it (so you don't accidentally start packing parts of it while you're using it or deploying parts of it while moving it). That way, an RBV (a motorhome) can have one room and toilet usable while on the road, and at least one more when deployed, maybe even have a system of solar tracking for solar panels which are protected between two walls while in transit/transport.

[@perpetual_bias]

and for crashing out of the race, you really decide to use grosjean's crash which had nothing to do with wheel alignment? what a buncha distasteful youtubers y'all are 0:40

awesome explanation, had been curious how this works.

that combined with BOSE Suspension ... Heaven

[@Stop_Pre-Ordering_Video_Games]

Very very cool, it will be great to see it in action

[@neilmckay8649]

Very clear explanation.

[@Lolatyou332]

The main benefit to an active wheel alignment is going to be completely flat on straight line (accel / braking) to allow for improved straightline traction. An additional issue with the existing camber system is that it's designed to only have the outside wheels (if you turn right, the left wheels are outside) as flat with the body roll. The inside wheels will ultimately only be using the very inside of the wheels due to both body roll and the camber. This doesn't matter too much as the outside wheels will almost always lose traction before the inside, but by having more grip on the inside it could definitely help aleviate some of the grip requirement on the outside wheels. For normal everyday vehicles this is irrelevant, the AWC will be too expensive and will likely just be another breaking point for the vehicles, especially since normal cars barely run any camber at all anyway, only sports cars need it since normal people don't even know how to push ANY vehicle to their limit successfully anyway.

[@cbremer83]

Combine this with four independent electric motors, and you will have a hell of a monster on your hands. Especially when/if batteries get lighter and higher compacity. Full toque vectoring and active alignment would be pretty crazy on the track.

[@Shwnm1490]

I remember seeing mercedes the w211 e class actively increasing negative camber as its speed increases while following it from behind many years ago.

[@black350Z]

In part of the explanation of camber, I think it's important to point out that the main reason we run negative camber is for the tire deformation under lateral load. During cornering, without negative camber, the tire will deform and roll underneath the wheel somewhat, shrinking the contact patch. More negative camber minimizes this. The suspension movement also plays into it, but it's the tire deformation under lateral load during cornering that is the main reason for camber changes.

[@captainwin6333]

That's pretty good on a smooth track but this system looks like it'll add a fair bit to unsprung weight which might cause issues on rougher roads (most of them).

[@m3lvin449]

Sick Video

[@ZephyrCubic]

A lot of modifications to alignment could take place as a transpostion of control arm pivots/mounts, which has the added benefit of of being sprung mass. Don't even want to think about the nightmare of suspension geometry that creates though... because of problems like bump steer, it would probably work best on cars whose steering per wheel is already variable, like variable ackerman

[@Bora_H]

Need 'steer my wire' for true independent motion. Cybertruck has it now. Interesting to see who will be next to do it!

[@GJBricks]

Something else to catch fire on a lambo :) Very cool tech when they work out the quirks.

[@K-SHABAB]

i thought i'am watching driver61 video great job ❤

[@ronstiles2681]

About time, great idea

[@nj1255]

Lamborghini is one of the last manufacturers I had expected something like this from. I wouldn't have batted an eye if it came from Koenigsegg, Bugatti, Ferrari or Porsche. It seems like Lamborghini hasn't tried to innovate in at least 15-20 years, but instead felt comfortable in just making exotic looking sportscars that are somewhat "affordable" (at least in comparison to Koenigsegg and Bugatti). This looks like an innovation that could catch on and become a must-have thing in supercars in the future.... if it works, that is. Bravo!

[@zbatchDOC]

0:45 I like how you chose THIS crash which, arguably, had absolutely nothing to do with the alignment XD

[@girafaamazonica70]

i thoght about this, thinking of doing a full adjustable car, not just toe and camber, also things like anti geometry... but i thought of doing it with the arms of the suspension, just like it is in every car, but with in cockpit adjustable... but this hub is increadible! i dont know how we just did it now, its so important that it should be more said than aero...

[@Pedro5antos_]

AWESOME idea!!

[@MihzvolWuriar]

I really want this and active suspension in a race car, imagine how much a lap time would shorten.

[@angerthosenear_yt]

It's interesting the motors are 48v. With the recent talks of trying to move to a 48v system in automobiles as a standard.

[@mndlessdrwer]

I can see this becoming an incredibly complex and electronics heavy steering augmentation system that utilizes the various impacts of camber and toe to help pull a car through corners with both greater grip and stability, similarly to how torque vectoring can. If it can be operated independently on each wheel then you can also use it to provide rear-wheel steering as well as ensuring proper Ackermann geometry for each end of the car, among other benefits. I can see how this could be developed into something that would shave seconds off lap times.

[@crisnmaryfam7344]

Google Nissan HICAS, 1988 1989..... theres a reason anyone whos anyone with one of these REMOVES this system. These Lambos will be the same. OR maybe not, maybe they will just be completely undrivable once they age.

[@mndlessdrwer]

@@crisnmaryfam7344It depends on how long they test and refine these before they actually end up on production vehicles. HICAS was always hamstrung by the inadequate processing power and sensors behind its operation. As long as this is electric and somewhat readily replaceable, we have fast enough processing and cheap enough sensors that it should be possible to achieve what HICAS wanted to be and then some. Still, I hope they let it develop through a few generations past the first successful design while it's still in the R&D process. It'll save them some recalls and poor public relations.
