20-22 years ago a couple of us modeled this on the PC -- our supposition was that a normal slide would burn off speed to about 183-185 and if so the car would tend to stay on the ground, but if the car got turned quickly and speed was still above 188 (I think that was the speed), flaps or no flaps the coefficient of lift of the car would give you aero lift (leading edge of car lifts first, as in this case) and away you go... they can fiddle with the shape/spoilers/flaps all they want, but physics hasn't change and at some speed the basic body area of the car will fly... the trick is a slow slide that burns off speed, then the roll if it occurs, will be to roll over the leading edge tires in the more typical roll-over...
That sounds like a CFD analysis. It looks like it is time to get the Aerospace PhDs running some new CFD simulations on this car. That is if no one is already looking into this.
@@ericschlichting7664 They spent millions to make this not happen. If they always will due to this person's physics experiment, then they spent money on something they can't fix. They are likely not going to run in the 170's at every track.
this plus conside where lajoie was when the car became unstable, right at the edge where all the high pressure air is getting dumped off of the #10. think this has a huge amount to do with how quickly it generated lift.
MIS used to be a plate track, but iirc they took the plates off because car wouldn't blow over as much due to the low banking (once they started tweaking the bodies to prevent it). They do need to slow these guys down a smidgen though, we've already raised the catch fence here twice, I don't think it'll be able to go much taller 😅 We probably should raise it again anyways after that tire flew over at the Indy race last year
Honestly I've noticed that with these next-gen cars they tend to flip on pavement.more than grass. I wonder if it's the are getting underneath the flat bottom of the car.
@@stephenullman4534 They may need to use the superspeedway package at Michigan in 2025. They will almost certainly have to slow the cars down. That said, speeds are only slightly lower at the 1.5 mile tracks (other than Atlanta)...
There was a Head wind down the back stretch today though I believe, so that would actually keep the Speeds down in this case…I suppose with a head wind, it could have caused the car to lift more when it got sideways which resulted in packing air under his car to send it over without the assistance of another car booting him like what happened Saturday.
I don’t know that it’s that crazy, the blower in the xfinity race happened like 20mph slower. I know they spent a lot of money but there is only so much you can do with something that shape. Every time this happens people forgot that it’s happened with every iteration of the car since the mid 70’s.
Well this confirms we have a roof flap issue. The Xfinity ones didn't deploy at all, and Corey's deployed for show but effectively did absolutely nothing. They need to completely rethink that concept.
Problem is the underneath of these cup cars. Gives the air barely anywhere to go so it just creates lift and sends them up like a piece of paper in a tornado
The panic over the flat floors... Blowovers have been a thing since the 70's. Maybe we should strive to not turn something with the aerodynamic properties of a brick sideways at 160+ mph. Just spitballing here.
Fr bro I’ve never liked Lajoie because what has he ever done. Plus he acts like he can do all this stuff, but honestly if he was in Hendrick equipment he wouldn’t even catch a top 5 every now and then
The fact that there was not a blow over wreck at Michigan for 24 years to then have two in the same weekend is insane. (The last one was Elliot Sadler in 2000).
Reminded me of the last Clash at Daytona and the wreck with the 48 and 21. I think as he went around him, the air pushed the car to the right. Possibly because of the headwind down the back.
The cause of the flip was due to head wind + a hole created at center of the car. As the car is turned 90deg the rear wheels are on the “inclined” racing surface and the front wheel are on the flat non racing surface making the center of the car high at the center. That is when the car start to flip.
It lifted when it hit the transition to the apron. The back stretch there is banked at like 6° or something close to a flat apron. It's going to happen at any track with higher speeds where air can effectively get under the car.
The flat underbodies Is what caused this and I feel NASCAR should take a look at it and not just brush it off cause this would've never happened in the gen 6 car
Unreal this happens at a non plate race with 34 degree banking and drafting the field. All the angles and it really looks like zero contact, maybe a slight kiss and over he goes. Amazing safety in these cars. Only a few pieces flew off, one a roof flap funny enough.
Too much air getting underneath these cars. Flat underside with the rear end diffuser and tire wells with big openings to trap air under them, they need to take a serious look at the belly of these race cards over the off season to fix this flipping issue...
I’m glad he’s ok that’s crazy seeing two flips at the same weekend I’ve been watching nascar since 2007 and I’ve never seen anything like that the two scariest crashes for me is Ryan Newman’s 2020 Daytona crash and Ryan preece 2023 Daytona flip if I’m not mistaken the last time a cup driver flipped in Michigan was Elliott Sadler in the nascar cup practice In 2000
I think it is where the 10 was relative to the 7 when he turned, couple with the speed. He was still on the 10's left rear, which would have disrupted the air across the top of the 7, which is ok in and of itself...but as soon as he turns and starts gapping the 10, air hits the top of the 7 again creating a quick low pressure condition across the rear of the car, enough to overcome the roof flap physics...and over she goes. If you watch close, the rear of the car lifts first.
Who’s f-ing idea was it to make the underside of these cars COMPLETELY FLAT?!?!?! When these cars get air underneath, WTF DID YOU THINK WAS GOING TO HAPPEN?!?!?!
NASCAR knows what they're doing. First, it's for ground force, which uses the air under the car to pull it down into the track and give the tires more grip. Secondly, it masks whatever secrets you have down there so competitors can't steal your exhaust design.
Ikr .. looks like one of the 1/24 scale diecast cars they sell .. the car gets sideways at that speed and turns into a big wing. One doesn't have to be an aero-engineer to see it.
Johnny Benson In 1993. Elliot Sadler In 2000. Kyle Sieg Last Week. And Now Corey Lajoie… HOW MANY FLIPS ARE WE GONNA HAVE AT MICHIGAN?! WE NOW HAVE 4 FLIPS AT MICHIGAN…
Regarding the cars getting airborne, it seems the passenger side window needs to be replaced with a window net. The air would go through the car and not act as a vacuum as it goes over the car. Plus, getting more air for the driver wouldn't be a bad thing and with the rear window slits, the air would also escape and not build up inside the car. Also, in another instance when a car turns backward, the spoiler needs be designed to let the air push it against the deck lid and not allowed to keep its angle up allowing air to lift the back end. Just saying.😊
The fact that we see it as "unacceptable" that a car flips when it crashes after going nearly 200MPH is almost laughable. Physics exists. I know there are extremely smart individuals working to make it impossible, but the reality is, without doing something drastic (like slowing the speeds or something) they aren't going to completely eliminate the possibility of these cars going airborne.
Im sure the flat underside certainly contributed, but this is likely a fluke to have 2 cars take off like this in the same weekend. Michigan is faster on the backstretch than the plate tracks, and add on the weather with the wind gusts down the back created a perfect storm for both of these
If you are going 200 mph, you are going to flip regardless. When you try and wreck people, you’re going for a ride putting your left front to their right rear.
A race car going faster than a fully fueled fully loaded 747 at take off and the car has a flat bottom. And nobody no why it got air and flipped? Really? WOW!!!
2 blowovers at the same non-plate track in the same weekend. If it wasn't obvious that these new cars catch air so easily, it is now. Hopefully nascar doesn't ignore it like they always do whenever something is obviously wrong with the engineering on new cars.
Knowing NASCAR these days they'll do nothing and brag that the safety features protected him instead of actually doing anything to fix it...especially since they've not fixed most of the other issues except making the car crumple more when they crash.
This car will eventually kill someone NASCAR supposedly had this problem fixed looks like they don't have control and it's obvious Corey why you're not driving a car next year that cost a lot of money today😂
Ran out of talent again. There is no reason to hit the 10 when he could clearly pass him. He did this to Brad K & wrecked him. I seen Corey do this to his own teammates. No a cup caliber driver & really he shouldn't be pissed at the 10. He timed his run all wrong. Amateur hour. Where the heck is the 10 going to be on corner exit? Sliding to the outside. Just a dumb dumb man.

It might be more than that. This track was a restrictor plate track.

Hope Corey is ok.

I personally don't think an undertray and diffuser belongs on a stock car but they designed a Trans-AM car for a circle track series.

Something that never happens at Michigan. When was the last time a car got upside down there? 1993 or 94?
The most recent in Xfinity is Johnny Benson Jr in 1993.
The most recent in Cup is Elliott Sadler in 2000.
And the most recent non-superspeedway flip blowover wise in the Cup Series was Brad K. in 2010 @ Atlanta.

It’s either draft turbulence sucked him into the left rear of the car he was trying to pass, or he just did a horrible job of trying to pass.

Instead of roof flaps of old, they need floor pan louvers to prevent this.
