Will chaos (and rain) reign on Daytona road course?

1 Comment

The biggest unknown for Sunday’s inaugural Cup race on the Daytona road course?

Ryan Newman says “there are so many unknowns that it would be fabricating for me to tell you if I knew what the biggest unknown was.”

But with all the uncertainties heading into the race (3 p.m. ET on NBC) on a new course for Cup teams — and no practice — Newman is counting on one near certainty.

“I hope it rains,” he said. “I hope you add in the extra that we have to bolt on rain tires and we get something that is just spectacular. I hope that. The reality is that could be the biggest unknown that we have. We’re in Central Florida in the middle of August when it pretty much rains every day. We’ll see. I don’t know. I look forward to it.”

Good chance he gets his wish.

The wunderground.com forecast for Sunday calls for isolated thunderstorms throughout the afternoon. The green flag is scheduled to wave at 3:24 p.m. ET. There is a 34% chance of isolated thunderstorms at that time. The chance of scattered thunderstorms increase in the afternoon.

Goodyear will bring rain tires for the weekend and teams will run in the rain, provided it is not a downpour and there is not lightning within an 8-mile radius of the track. Cup teams have never run a race on rain tires.

Only three times in Cup history have rain tires been employed. Dale Earnhardt and Mark Martin used them in a test in 1995 at Watkins Glen. Teams practiced and qualified on rain tires at Suzuka in 1997 for the exhibition race in Japan. Rain tires were last used in Cup for a practice session at Watkins Glen in 2000.

Rain or shine, the task of racing on a new course without practice will be challenging enough for competitors.

“On a scale of 1 to 10, 10 being difficult, this is a 10,” Kurt Busch told NBC Sports.

“I’m excited for the challenge, the uniqueness of it all, how it’s just crazy, basically.”

Said Chase Elliott, who won last year’s race on the Charlotte Motor Speedway Roval after crashing: I’ve never entered a race where you literally just have no idea what to expect.

Patience will be key. But not all 39 drivers will practice that equally when the green flag waves.

“I’ve got laps around that track without the extra chicane but that doesn’t mean I won’t haul off into Turn 1 and blow through the grass,” Newman said. “You don’t know. It will be more patience than aggressiveness I promise you by pretty much everyone. Those that don’t, you’ll notice.”

Kevin Harvick, who swept the Cup races at Michigan last weekend, will lead the field into Turn 1 and he’s not sure what to expect.

“I think me leading everybody into Turn 1 at Daytona could be interesting because I have no freaking clue where I’m going as we go down there,” he said. “Most everybody in the field is the same way.”

Turn 1 on the Daytona road course is a left-hand turn off the frontstretch just past pit exit. That begins the six-turn infield portion of the 3.61-mile course before cars return to the oval in what is its Turn 1. 

Teams stay on the oval through the backstretch before turning into the chicane there and going back on to the oval. A chicane was added off what is Turn 4 on the oval to help slow the cars before returning to the infield portion of the course. That was done for fear that the high speeds would wear the brakes over the race.

“I think it’s going to take everybody a little bit of time,” Matt Kenseth told NBC Sports. “I think there are going to be some people who have raced road courses a lot that probably feel more confident than others and possibly be overzealous and just charging it hard right away, and there’s probably going to be other people who are careful and see how many people slide into things. … It should be really interesting. If I was a fan, I’d be all about not having practice.”

Dr. Diandra: How level is the playing field after 50 Next Gen races?

0 Comments

Last weekend’s Coca-Cola 600 marks 50 Next Gen races. The 2022 season produced 19 different winners, including a few first-career wins. Let’s see what the data say about how level the playing field is now.

I’m comparing the first 50 Next Gen races (the 2022 season plus the first 14 races of 2023) to the 2020 season and the first 14 races of 2021. I selected those two sets of races to produce roughly the same types of tracks. I focus on top-10 finishes as a metric for performance. Below, I show the top-10 finishes for the 13 drivers who ran for the same team over the periods in question.

A table comparing top-10 rates for drivers in the Gen-6 and Next Gen cars, limited to drivers who ran for the same team the entire time.

Because some drivers missed races, I compare top-10 rates: the number of top-10 finishes divided by the number of races run. The graph below shows changes in top-10 rates for the drivers who fared the worst with the Next Gen car.

A graph showing drivers who have done better in the next-gen car than the Gen-6 car.

Six drivers had double-digit losses in their top-10 rates. Kevin Harvick had the largest drop, with 74% top-10 finishes in the Gen-6 sample but only 46% top-10 finishes in the first 50 Next Gen races.

Kyle Larson didn’t qualify for the graph because he ran only four races in 2020. I thought it notable, however, that despite moving from the now-defunct Chip Ganassi NASCAR team to Hendrick Motorsports, Larson’s top-10 rate fell from 66.7% to 48.0%.

The next graph shows the corresponding data for drivers who improved their finishes in the Next Gen car. This graph again includes only drivers who stayed with the same team.

Alex Bowman had a marginal gain, but he missed six races this year. Therefore, his percent change value is less robust than other drivers’ numbers.

Expanding the field

I added drivers who changed teams to the dataset and highlighted them in gray.

A table comparing top-10 rates for drivers in the Gen-6 and Next Gen cars

A couple notes on the new additions:

  • Brad Keselowski had the largest loss in top-10 rate of any driver, but that may be more attributable to his move from Team Penske to RFK Motorsports rather than to the Next Gen car.
  • Christopher Bell moved from Leavine Family Racing to Joe Gibbs Racing in 2021. His improvement is likely overestimated due to equipment quality differences.
  • Erik Jones stayed even, but that’s after moving from JGR (13 top-10 finishes in 2020) to Richard Petty Motorsports (six top 10s in 2021.) I view that change as a net positive.

At the end of last season, I presented the tentative hypothesis that older drivers had a harder time adapting to the Next Gen car. Less practice time mitigated their experience dialing in a car so that it was to their liking given specific track conditions.

But something else leaps out from this analysis.

Is the playing field tilting again?

Michael McDowell is not Harvick-level old, but he will turn 39 this year. Ricky Stenhouse Jr. is 35. Both have improved with the Next Gen Car. Chase Elliott (27 years old) and William Byron (25) aren’t old, either, but their top-10 rates have gone down.

Drivers running for the best-funded teams earned fewer top-10 finishes while drivers from less-funded teams (mostly) gained those finishes.

Trackhouse Racing and 23XI — two of the newest teams — account for much of the gains in top-10 finishes. Ross Chastain isn’t listed in the table because he didn’t have full-time Cup Series rides in 2020 or 2021. His 9.1% top-10 rate in that period is with lower-level equipment. He earned 27 top-10 finishes in the first 50 races (54%) with the Next Gen car.

This analysis suggests that age isn’t the only relevant variable. One interpretation of the data thus far is that the Next Gen (and its associated rules changes) eliminated the advantage well-funded teams built up over years of racing the Gen-5 and Gen-6 cars.

The question now is whether that leveling effect is wearing off. Even though parts are the same, more money means being able to hire the best people and buying more expensive computers for engineering simulations.

Compare the first 14 races of 2022 to the first 14 of 2023.

  • Last year at this time, 23XI and Trackhouse Racing had each won two races. This year, they combine for one win.
  • It took Byron eight races to win his second race of the year in 2022. This year, he won the third and fourth races of the year. Plus, he’s already won his third race this year.
  • Aside from Stenhouse’s Daytona 500 win, this year’s surprise winners — Martin Truex Jr. and Ryan Blaney — are both from major teams.

We’re only 14 races into the 2023 season. There’s not enough data to determine the relative importance of age versus building a notebook for predicting success in the Next Gen car.

But this is perhaps the most important question. The Next Gen car leveled the playing field last year.

Will it stay level?

NASCAR Cup playoff standings after Coca-Cola 600

0 Comments

The severe penalty to Chase Briscoe and his Stewart-Haas Racing team Wednesday for a counterfeit part dropped Briscoe from 17th to 31st in the season standings. Briscoe now must win a race to have a chance at the playoffs.

The penalty came a day after NASCAR suspended Chase Elliott one race for his retaliation in wrecking Denny Hamlin in Monday’s Coca-Cola 600. Elliott is 28th in the points. The 2020 Cup champion also needs to win to have a chance to make the playoffs.

Ten drivers have won races, including Coca-Cola 600 winner Ryan Blaney. That leaves six playoff spots to be determined by points at this time. With 12 races left in the regular season, including unpredictable superspeedway races at Atlanta (July 9) and Daytona (Aug. 26), the playoff standings will change during the summer.

Among those without a win this season are points leader Ross Chastain and former champions Kevin Harvick, Brad Keselowski and Elliott.

Here’s a look at the Cup playoff standings heading into Sunday’s Cup race at World Wide Technology Raceway in Madison, Illinois. Drivers in yellow have won a race and are in a playoff position. Those below the red line after 16th place are outside a playoff spot in the graphic below.

NASCAR issues major penalties to Chase Briscoe team for Charlotte infraction

0 Comments

NASCAR fined crew chief John Klausmeier $250,000 and suspended him six races, along with penalizing Chase Briscoe and the No. 14 Stewart-Haas Racing team 120 points and 25 playoff points each for a counterfeit part on the car.

The issue was a counterfeit engine NACA duct, said Elton Sawyer, NASCAR senior vice president of competition. That is a single-source part.

The team stated that it accepts the L3 penalty.

“We had a quality control lapse and a part that never should’ve been on a car going to the racetrack ended up on the No. 14 car at Charlotte,” said Greg Zipadelli in a statement from the team. “We accept NASCAR’s decision and will not appeal.”

Asked how then piece could have aided performance, Sawyer said Wednesday: “Knowing the race team mentality, they don’t do things that would not be a benefit to them in some way, shape or form from a performance advantage.”

The penalty drops Briscoe from 17th in the season standings to 31st in the standings. Briscoe goes from having 292 points to having 172 points. He’ll have to win to make the playoffs. Briscoe has no playoff points at this time, so the penalty puts him at -25 playoff points should he make it.

Briscoe’s car was one of two taken to the R&D Center after Monday’s Coca-Cola 600 for additional tear down by series officials.

The penalty comes a day after NASCAR suspended Chase Elliott one race for wrecking Denny Hamlin in last weekend’s race at Charlotte Motor Speedway.
