Unlocking the Aerodynamic Secrets of the Pikes Peak Enviate Hypercar | Lifting The Hood 

Great talking to Sebastian about the aero, for more info on the mechanical aspects of this car, check out the High Performance Academy video here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-9eUt7BbiYZk.html as well as my interview with the owner here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-8E7DoD0EVfY.html Thanks for watching, and enjoy!

Wow that is the frenchest accent of all time

Thanks Kyle, Seb is an amazing resource for a little team like ours to have, he is not only crazy bright and experienced but as you can see is the exact opposite of the supposedly pretentious folks in F1, just a joy to work with. I will also point out that the car drove exactly as his modeling predicted as far aero balance and migration with speed, it was all perfect. He, one other engineer from Sauber, (Manuel Grenier) and Aric Streeter nailed the chassis as well. It was a treat to drive and we can't wait until next year!

Brilliant stuff, this kind of CFD discussion is impossible in F1 where all designs are secretive. Thank you for posting this!

man, this guy is really cool! he doesn't keep his amazing aero in secret.

Sebastian seems like a cool dude. Always fun to hear someone talk about something about which they have tons of knowledge!

It's a shame this video isn't another 45+ minutes long. Though I'd like to hear more about suspension geometry, and suspension tuning as well.

Recording in a cloud makes for a pretty cool video! It's also very cool to hear all of this info from someone involved in F1!

so i guess this is what group c would look like in 2017

This was great Kyle. This re-affirmed all of my understanding and practice on aerodynamics on racecars at a pro-am level in motorsports over the last several years and all the literature i've gone over. This is a great design and hearing it explained so simply from a person who has a very advanced understanding of how it actually works.

This is excellent to watch, challenging conditions are disregarded by me. I've been on top of Pikes Peak and it looks like it is snowing and you have race cars running nearby. It is awesome to watch Sebastian speak so passionately about his work and I think you did a great job interviewing him.

I'm 100% french and can't pull a french accent like that ^^ Well... I can't pull off a car like that either...

Thanks for doing this interview! Brilliant insights about the aero design, what a unique vehicle, such intriguing design overall (not just aero)...

Guys, don't hate him for his poor English. Be thankful, that one of the five english speaking French talks about interesting stuff!

Kyle you really have something here, but cant understand. It would be help full you went back to the white board and explained some the the ideas and concepts that you ran across at PP. S

What a great French man, thanks both of you :)

Loving these vids Kyle. So interesting to see designs form other people and seeing them practiced in the real world. But please make a part 2 to all of these explaining the aero concepts like you do so well. I love learning about this sort of thing.

Deep, deep respect for the people racing Pikes Peak. I've ridden Pikes Peak on my motorcycle, at a very leisurely pace, that mountain is scary! The other issue for designing the aero for a competitive car is that the air on top of Pikes Peak is a lot less dense than at the bottom. It was very noticeable how thin the air is on top.

Great work Sebastian! Thank you Kyle. Looking forward for more of your videos.

Well done Sebastian! one of my favorite cars for sure, keep it up

Very surprised to see the lack of a gurney flap on the trailing edge of the rear bodywork. He was talking about trying to increase the extraction of air from the diffuser and that seems like the best way to do it in conjunction with the rear wing. Sure you might have to raise the rear wing a bit to keep that laminar, low pressure, air attached to the wing but it would be an excellent addition.

I've been waiting three years for this video. 👍 Great work as usual, keep it up Kyle!

Fantastic video, Kyle! You and Sebastian made it amazing!!!

Thank you kyle!.....and,,Whaaaaaat!!! 2800 kilograms DF, is this the highest DF I've ever witnessed? Wooooow. I'm keeping a closer eye on pikes peak from now on.

can the wheel/wheel spokes be made to act as vanes to draw air from under the car?

I can't help but wonder what percent of british aerodynamicists are employed by F1. Speaking of F1, I've been wondering why tire compliance doesn't interfere with aerodynamics but suspension compliance does. I learned recently that tire manufacturers don't really like making F1's weird tires, because nothing else uses anything even similar. And speaking of Sauber, I can't help but think that their funny intake design is meant to shrink the effective size of the inlet at high speed to reduce drag.

Fascinating insight into unlimited aero

Love you Seb !

At the end of the day it's probably like this: there's this list of stuff that you can do to improve a cars handling or aerodynamics and the more you can tick off the list the better. Even if it might not have all the big things checked off it might work as a vehicle, but the more of the big things the car's got together the better the end product/result is.

Awesome video about the aero of this car. I'm just curious, with the less dense air at the top of the mountain, what effect does that have on the overall downforce on a car? I genuinely don't know. Do you lose a significant amount of downforce due to the less dense air or is it negligible to the driver? Also, you were stating about the static ride height, how much would you expect the height to change as you approach top speed? It will be due to the compression of the suspension, of course, but would 5-10mm be expected or is that too much? I have a fascination with the science of aero 😉Cheers

Such a shame Sauber F1 have a 2016 spec engine. I wonder how they would go with a Merc engine

Outstanding content, thank you.

pretty cool discussion. The wing position relative to the diffuser is similar to the old Toyota and Jaguar IMSA cars. IIRC the IMSA cars back in the day ran a lot more downforce than the FIA cars because a lot of the US races were on tight street courses or speedway infield courses. What would've been interesting is for him to just have noted quickly where the car has features that break the current LMP1/2 aero rules. They may have missed a trick with the low nose Since Pikes Peak unlimiteds are open I wonder whether unsprung wings back and front, side skirts and maybe even fan sucking with some active aero features might be the way to go? This is the only current place I know of where you can basically run anything and I'd love to see somebody really push the configurations.

“Most interesting rear end” ...that’s what she said! 🤘🏼🤙🏼💪🏼

Please do a follow up video this year of how they changed the car and what they did and maybe a comparison and explanation if possible!

Nice, he's got the inter cooler layed out the way I would have it layed out as apart of the natural lines of the car instead of hidden inside a duct which causes drag.

Interesting to hear him talk about the rear fender when Cody said it is cut because of tire clearance (Afaik)

Very passionate about his car! great video!

This video should be renamed as: "YTP How to sound like you don't know what you are talking about - in french accent.mp4"

Amazing content, as always! Keep the good job :)

Idk much about aerodynamics but is that a NACA duct on a low pressure region?

I could understand the part where he said about keep the rear wheel open so positive pressure can build up and increase down force?? I understand how positive pressure can build up in front of the rear wheel, but how does that play into the “increase down force”? Edit: ohhh, I get it! Is it because the air pressure build up in the wheel house would start to lift the car causing a negative down force?

hey Kyle....please do a video on aero of Apollo IE , with all of its sharp edges nd teeths and a shark-fin type column mounted rear wing.... does its dedign seem over intricate for aero advantage??!

They should have this kind of discussions in Formula 1 - but it get it that everything is secret there, so they could only use older cars. Still it could be interesting to review last year`s cars or something.

so does that front splitter have a wing profile? it looks more like a very large front wing because the trailing edge has a gap behind it rather than connecting to the undertray. Can you shed some light on that please? thanks

J'aime ce belle Accent ! Je dois bien avouer que je me sens ridicule aussi quand je parle anglais :P

Very interesting video.

love his accent

Sorry, I had to put the subtitle because the "uhhh, uhhh " was annoying. But the video content is brilliant.

Nice interview. You should correct his name in the commentary, it's Lamour, not Lemour.

Are ducted fans allowed on pikes peak?

Is downforce measured in kgs?

Not covering the rear wheels is bonkers. You can't justify that, even though he tried to.

I wish they would talk about how the lower air pressure of the mountain affects the agressiveness of the measures used compared to sea level cars.

baguette intensif

I wonder why they didn't try unsuspended aéro....

Wouldn't a custom f1 car be faster? Surely you could buy an old toro rosso or force india for less than the cost of developing a new racecar.

As you can guess my accent, I'm from fr0nce!

This guys accent is very cool

Fronnce

Why show Sebastian Lamour so much ??? We want to see THE CAR !!! He explains something on the car, but the camera is on him, not what he is talking about !! Makes no sense !! An excellent video became a below average video . :(

Aero has to look good in my opinion and that car looks ugly with its body on...sorry...

I gave up listening to his poor English.

Say "UHHH" one more time

Annoying camera man.

Mate im not here to see the face of this guy.... Next time give a close look to the car at same time try just to capture the voice of the guy... will be more interesting... or put up a nice female than forget the car otherwise dont do this anymore... dislike...
