See the two Twitter posts below the gif. It better explains what was going on and the rules for the Next Gen when it comes to having skew in the car:

Now we know why.

The rear end of this car has less metal being the rear wheel; which means that under normal circumstances in a corner, there's less sheet metal to point the car straight.

This car has a giant pan underneath it; which means that the aero grip is being produced further forward and as the teams are trying to make the car point and tighten it up, that leads to the rear right wheel loading up.

Further to that, the aspect ratio of the tyres is way way less; which means that they don't dissipate heat as well.

The threefold problems add to a more taily car.

I want to know if we're going to see more of this in 2022.

The car will have had its weight transfer to the front under braking; which changes the moment of rotation. That in turn means that the rear end of the car has acted like a giant pendulum.

I suspect that this year will have a lot of teams trying to work out how to play the brake bias game and try to stop this from happening.

NASCAR Wraps Final Next Gen Organizational Test at Phoenix Raceway (credit to MRN):

aaNGPHX-74.jpg


NASCAR‘s 2022 Next Gen testing schedule started and ended at the same destinations the official season will begin and conclude — Daytona International Speedway and Phoenix Raceway.

There was a two-day organizational test Jan. 11-12 at Daytona and then another this week at Phoenix. Wednesday‘s eight-hour session marked Day 2 and therefore the last preseason opportunity for teams to turn laps on track. They‘ll next unload with a checkered flag on the line.

“I think that, from my gray hair, we‘ve all done this long enough to know that this is testing,” NASCAR senior vice president of racing innovation John Probst said. “We‘ve done it throughout our history. And from what we‘ve seen right now, we feel like we‘re in a really good spot. But until we throw the green flag and guys go out there to race, with some anger and really start bumping and banging… Right now, we‘re really happy. We‘re also prepared to monitor how the season starts and we‘ll be prepared to make adjustments if we need to. But right now, all indications are pretty good.

“Experience tells us not to get too happy, so we‘ll just be cautiously optimistic, how about that?”

Phoenix‘s shakedown was more so for teams than NASCAR. The sanctioning body monitored tire wear and debated inspection processes, but otherwise, its personnel simply shadowed the garage unless an issue arose.

Feedback from drivers varied from stall to stall.

“We may have some general ideas, but there‘s nothing concrete yet until we go out there and race,” Team Penske wheelman Joey Logano said. “So, when you say comfortable, I‘m far from comfortable. There‘s nothing I really know for certain is coming my way.”

A very different vibe from Trackhouse Racing Team‘s Daniel Suarez.

“I don‘t have, honestly, one thing that bothers me about the car,” he said. “That‘s my honest opinion, so I‘m happy. I‘m happy for the change. I‘m happy for where the sport is heading. And I can‘t wait to get started.”

There are others who have adopted more of a laissez-faire attitude, too.

“Once you get the first five races, you kind of have a good dialogue and a good direction of where your team is, so just grind through it,” 23XI Racing pilot Bubba Wallace said. “This car is so tricky, and it‘s a lot to take in. Every lap on track, I kept getting more and more comfortable. It‘s just a matter of time before it all clicks.”

And it could very well all click — at different times, for different teams.

“I’m anxious to go through that learning process and kind of see who guesses right first, and hopefully it’s us,” Hendrick Motorsports‘ Chase Elliott said. “Then, whether it is or isn‘t, you definitely want to make sure you‘re on the upswing at the right time, like always, and I think that swing is going to be a pretty big one this year.”

That was — still is — the whole point.

NASCAR introduced the idea of Next Gen in 2019. The actual product will competitively debut here in 2022.

“I feel like we‘re a sports team,” Probst said. “We‘ve been practicing for three years, and now it‘s time to put the uniforms on and get out under the lights and see what we‘ve got.”

To answer your first question - YES..... We are going to see this more in 2022. :)

Well, Larson won the Pole at 181 MPH at Daytona.... Cup cars were not this slow since the 60's... 180 in 1968 to be exact. Cale hit 188 in 1969...

I guess Nascar knows what it is doing.

@Highbank said in the shoutout he gives the Next Gen car an 'A'.... I can't give it an A yet, maybe a B.. The racing a Fontana was pretty good, but I think a lot of that was to do with the old worn out track surface. Vegas could be a better test for how the racing will be.

Right now the 2nd tier series (Xfinity) is faster than the Cup cars... At Fontana AJ won pole at 179.8 - Cindric won the Cup pole at 174.6 and they look slow to me and I thought the Next Gen cars looked real slow at Daytona in the Tri-Oval.

I think the cars come apart to easy in a wreck and seem very unstable. Once again it could be the tracks.

Also, I give the new GOODYEAR tires an F. Never seen so many flat tires. Where are the inner liners? I hope they fix it soon.

@Highbank also said lets see what the road courses are like for the Next Gen Car - I Agree with that.

Ok... I've decided this Next Gen Car is junk.. that's why K Busch blocked pit road yesterday at Darlington, to protest his displeasure. That hit on front end by the 6 car, broke left spindle. I'm sorry, but that hit on his car, the 23 and 19 later all broke same part.. on last year's cars, that hit would not have taken out any of them. Worst thing maybe would have been to knock car out of alignment, which can be fixed on pit road.

Passing is a joke, you have to knock car in front of you too pass or time your closing rate just right. What I saw on TV yesterday is not racing.. sorry NASCAR but the new car has to go.

What you saw yesterday re Logano nudging Byron, was both retaliation and opportunism.

This has been a thing for at least 30+ years.

I'm not so upset with the bump or nudge, but I really upset with is the Car itself... 4 or 5 cars were knocked out with the same issue, front tie-rod can't take a hit of any kind. Passing is at a premium... There just isn't enough adjustability in the suspension so cars and drivers can make a difference..

Once again that was not racing yesterday... NASCAR thinks so, I don't.

I am not sure that claim holds up statistically:

The 2022 campaign has seen an incredible average of 45.8 green flag passes for the lead per race, which is up 25 percent on average for the first nine races of a season – dating back over 16 years when Loop Data statistic was initially tabulated, where the average was 33.8 per race).
- Talladega Superspeedway website, 20th Apr 2022

Data is beautiful. I need more.

Statistically - Maybe, but does it say when the passing happened? No, but I can tell you it was after a Yellow or Stage and they go back to green.. Case in point, Las Vegas - 23 lead changes, but there were 12 yellows, 1 competion Yellow and 2 stages, there was a lead change after everyone of them...

Martinsville - only 5 lead changes among 4 drivers - in 2021 there was 18 lead changes and in 2020 - 14...

I don't count Daytona and Talladega - everyone is pushed into lead. can't do it by yourself and that's with any car.

Also I'm looking at Jayski race results, where is the 45.8 green flag passes for the lead per race coming from?
Daytona - 35.... Auto Club - 32... Las Vegas - 23... Phoenix - 14... Atlanta - 46(check).. COTA - 14... Richmond - 14
Bristol - 6... Talladega - 41... Dover - 17... Darlington - 24... These are from the NASCAR race page Results.. Someone has their figures wrong.. The more data doesn't add up.

Still don't like the Next Gen Car...

the car was made to be better on the bigger tracks not the small tracks

I am still quite undecided about this car. Certainly we've seen more issues with broken spindles and that is quite distressing. There is also the issue of the single lugnut which again has caused more issues with lost wheels than I've seen in years.

The car itself is quite unstable which some may view as a good thing with much of the success now up to the skill level of the driver.
On the flip side, it causes less skilled drivers to wreck and all too often take out other cars because of the tight racing packs. Example was Kyle (running in 5th place) gets taken out by a spin from a lap down car.
Fairly certain the 1 was headed for yet another win prior to his wreck.

As far as the "bump and run" by Joey is concerned, while I will agree it's a dirty race style, it's certainly nothing new. Earnhardt made himself the most loved / hated driver for his habitual "bumps"

1st... it's not a lugnut as it doesn't sit on a stud.

It's a center lock nut on a wheel hub/spindle.

2nd... the thread is directional. So the lefts do not tighten the same as the rights.

IMO the crews are still on muscle memory where they hit the wheel, hit the switch, hit the wheel. Doesn't work with the new wheel.

F1, GTs, Sportscars/Protos and any other car/series that uses this style doesn't have issues.
