William Byron beats Paul Menard in duel to win Xfinity race at Indianapolis

By Daniel McFadinJul 22, 2017, 5:56 PM EDT

In his first race at Indianapolis Motor Speedway, William Byron outdueled Paul Menard in the closing laps to win the Xfinity Series’ Lilly Diabetes 250.

The 19-year-old is the youngest NASCAR driver to win at the 2.5-mile track. It is the rookie’s third win.

Fighting a tire vibration, Byron led the final 16 laps. He beat Menard, Joey Logano, Elliott Sadler and Cole Custer to the win.

The victory comes three weeks after Byron also won at Daytona International Speedway.

“I just have to thank God, it’s amazing to be here,” Byron told NBCSN at the start-finish line. “I got a lot of great people around me. This is very humbling to be at Indianapolis and win. I can’t believe that tire held on.”

Byron led 26 laps in a race that saw a track-record 16 lead changes among eight drivers, the result of a new package that includes restrictor plates.

“We had vibrations for probably the last 20 laps or so, and it kind of leveled off,” Byron said. “I’m not a tire expert, so I was just trying to think about what it would do. It held on, and I’m thankful for that.”

Stage 1 winner: William Byron

WHO HAD A GOOD DAY: Paul Menard finished second for his best result of the year. His previous best in five starts was seventh at Michigan … Elliott Sadler led 22 laps from the pole and finished fourth for his eighth top five of the season … Cole Custer finished fifth for his third top five … Kyle Busch, who won the last two Indy Xfinity races, finished 12th after leading 44 laps. He pitted from the lead with 18 to go because of concern for tire wear.

WHO HAD A BAD DAY: Tyler Reddick was eliminated on Lap 38 after plowing through the grass in Turn 4 to avoid an accident with Ryan Sieg and Spencer Gallagher. Reddick finished 37th with his second DNF of the year. … Justin Allgaier finished 35th after multiple mishaps on pit road, including hitting his jack man (who was uninjured) and later leaving his pit box while his right-front tire was being removed, which caused severe damage to his No. 7 car.

NOTABLE: Byron’s win snaps Busch’s streak of four straight NASCAR wins at Indianapolis over the Xfinity and Cup series … Erik Jones‘ No. 20 Toyota had one unsecured lug nut following the race.

QUOTE OF HE DAY: “They wanted to slow down the fastest guy here so the rest of the field could keep up and they did.’’ – Kyle Busch

WHAT’S NEXT: U.S. Cellular 250 at Iowa Speedway at 3:30 p.m. ET on NBC on July 29.

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

By Diandra Leslie-PeleckyJun 1, 2023, 12:00 PM EDT

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.

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.

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 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

By Dustin LongMay 31, 2023, 8:36 PM EDT

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

By Dustin LongMay 31, 2023, 4:41 PM EDT

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.
