Hello, everyone and welcome in this video
We're going to be talking about how the active aerodynamic system on the lamborghini huracan performante actually works
And so you know there's two areas where this is going to be applying
These active aerodynamic techniques at the very front on the spoiler
And then of course with the rear wing and so how the front of this works is there's a little flap
In that front spoiler and so you know when it's closed
Your air is going to pass through go through your engine radiator ETC build up this high-pressure area above that front spoiler
And then you'll have some air passing underneath
But you're gonna have a lot of drag and you're gonna have a lot of downforce now you have this little hinge
Right here which opens up this flap and allows that air that otherwise would build a high pressure area to escape underneath the vehicle
and so that's going to reduce the amount of drag that you have and also increase the amount of lift that you have
so you're going to reduce your downforce and you're going to reduce your drag and so of course there are certain scenarios
Where this is ideal now for the rear wing you have this channel where you're taking air flow from ahead
And you're redirecting it upward
Toward the wing and so what you have is this little hinge right here this flap that can open or close and
When it is closed you're going to have clean air along that rear wing above and below
So you're going to have nice flow that's connected to the wing and will produce that nice downforce as it's passing through
But you're also going to have a lot of drag as a result of creating that downforce
So when you open this valve right here
What that does is allow for the Airflow to interfere with the smooth airflow underneath the wing and so by separating that Airflow
beneath the Wing you're going to
Disrupt that low-pressure side and create turbulent air behind it and so ultimately what you're going to doing by disrupting that Airflow is
Reducing the amount of downforce that it's creating and reducing the amount of drag that it's creating
So you know what are some scenarios where each of these would be ideal
Well under braking you're going to have the Ala system off that means both your valves are going to be closed
This is going to maximize your downforce in the front and the rear and it's going to improve your braking not only because you have
More downforce to help brake with those tires, but you also have more drag to help slow the car down
aerodynamically
With full throttle if you're going straight ahead you just want to be able to accelerate as fast as possible
So you're going to turn the Ala system on its going to open up both of these so you're going to allow that air to
Channel through up the front and you're going to allow the air to channel here
so you create that turbulence at the wing and you don't have as much drag or downforce?
So the car is going to be more slippery able to accelerate quicker and able to reach higher speeds
Now the interesting part where it kind of gets into this marketing twist rather than you know necessarily
100% engineering factors this thing called Aero Vectoring and so lamborghini says that this
Will provide you know improved cornering speeds and reduce the amount of steering
The amount that you need to turn the steering wheel now this probably can be true
So let's say your cornering and you put more so what you're doing is as you go around that corner
You're putting more downforce on the inside rear tire than on the outside rear tire
and so if you're braking if you're coming to that corner
And you're breaking that inside left tire
Can have more grip to break more and as a result can help pivot the car which means you don't have to use the steering
Wheel as much to pivot it you can use the braking to help pivot it that I do agree makes sense
You can also reduce body roll
by having you know the car obviously is going to send load transfer to the outside tire as you're going around that corner and by
Putting more aerodynamic pressure on the inside you can help mitigate that body roll
I don't think that's the the pure reason they've done that you know you can you can of course alter that with suspension settings
And so this claim about faster cornering
This is the interesting part because if you have more
downforce on the inside and less downforce on the outside
If your outside tire were to have more downforce which it's capable of because you've opened up that flap behind it
You've got flaps on each side, so you know you can open one here, and you can leave one closed here
So this has a lot of downforce and this one has less downforce a less drag
You could close this have more downforce give the outside tire more grip and then in theory corner faster because you have overall
More downforce so I don't think from a cornering speed perspective
This is helping it could help you rotate and breaking that make sense it could certainly help
reduce Body Roll
but I don't think it's necessarily going to improve your cornering speed another interesting thing that I think helps prove that point is that
Lamborghinis head of aerodynamics was asked whether or not they used
This arrow vectoring in the front of the car
[you] know you could have flaps on either side and open one side versus the other he said they did not because there was no
Performance Advantage
And so I think you know
Realistically the huge advantage comes from braking in full throttle where you can alter it to suit those needs that makes a ton of sense
For cornering not quite as much
But perhaps you can use a little bit less steering angle because you're going to be breaking that inside tire a little bit more
There are real advantages to a system like this though, which I do want to point out. It's less weight
They say they can save up to]80% versus a hydraulic system
Simply using these little electric motors and not actually you know
they're not taking a huge wing and moving it up and down and using all that hydraulic fluid and
System required to do that the wing is fixed it stays there
And they simply alter the air flow around the wing in order to optimize it for the conditions that it's driving
It's also a very fast-acting system
They say they can open and close these valves
in point to seconds (0.2s) so versus a hydraulic wing you know which may take more time to lift up or lower down
depending on the scenario you're in so very fast acting so both of those very real benefits very real benefits for
Braking and for for full throttle I'm not totally convinced that in cornering
It's honestly going to make a huge difference to me the most logical approach if you want the highest cornering
speed you want the most downforce you can possibly have and so you would do that by [just] simply
Closing off these valves and allowing for maximum downforce, so if you have any questions
