Dr. Diandra: Darlington mellowed over decades but still one of NASCAR’s toughest tracks

0 Comments

No driver is likely to call Darlington Raceway “mellow” but numbers show that the track has mellowed a little with age. Even so, it remains one of the most challenging tracks on the Cup circuit with one of the most prized trophies.

A true “crown jewel.”

Darlington was not part of the NASCAR’s inaugural 1949 season, but it’s been on the schedule every year since then. Its 1950 inaugural race scored a plethora of firsts — the first 500-mile NASCAR race, the first race on an oval track longer than 1 mile, and the first race on a paved track. Today, it offers speed and a craggy track that’s hard on tires.

In honor of the upcoming throwback weekend, I survey seven-plus decades of racing at Darlington Raceway to show how the nature of racing at “The Lady in Black” has changed.

The Winners

I chose one Darlington race from the start of each decade as representative. In years with multiple races, I used the spring race. The table below lists the winners, polesitters and the drivers who led the most laps for each race.

The winners are a who’s who of NASCAR drivers — with perhaps one exception.

Johnny Mantz was better known as the first USAC Stock Car national champion and an Indianapolis 500 competitor. Darlington was Mantz’s only NASCAR victory in the 12 Cup Series races he ran.

David Pearson appears twice on this list, which is fitting: Pearson has the most career wins (10) and the most poles (12) across a total of 47 races run at Darlington.

Twelve drivers have won from the pole at Darlington a total of 21 times. Only twice has it happened in this century, however: Kevin Harvick in spring 2014 and Joey Logano in spring 2022. Pearson also holds the record for most wins from the pole with four.

Out of 123 Darlington races, the driver leading the most laps won 53.6% of the time. Don’t try to extrapolate that statistic to this weekend. Only 11 of those 66 races won by the driver who led the most laps happened in 2000 or later.

Dale Earnhardt edges out Pearson for most times leading the most laps and winning the race. He accomplished the feat eight times to Pearson’s seven.

Races — and track — lengths changed

Darlington’s track changed length over the years due to reconfiguration. The original 1.25-mile track was enlarged slightly in 1953. Installing a retailing wall in 1970 cut the length back to its current 1.366 miles.

Track length changes were minimal compared to changes in race length. Neglecting rain-shortened races, the majority of Darlington races are 400 or 500 miles, although a number of races in the 1960s were closer to 300 miles.

That very first 500-mile race in 1950 took over six-and-a-half hours to complete. It was not the longest Darlington race, however. The fall 1952 race (also 500 miles) broke the 400-minute mark at 6:42:37. That comes out to 80.4 minutes for every 100 miles — and there were only seven cautions.

The fastest Darlington race pace was in 2013. In the single race that year, drivers needed only 42.3 minutes for every 100 miles, including five cautions.

The field and the schedule

One reason that first 1950 competition took so long to complete is that 75 cars started the race. NASCAR had to line up the cars in rows of three to produce a reasonable starting grid. When watching Sunday’s race, take a moment to imagine adding 39 more cars. The most cars ever squeezed onto the grid was 82, in 1951.

The table below shows how the number of cars finishing on the lead lap has grown over time, as well as how the numbers of DNFs have come down.

A table showing how Darlington has mellowed over the years via numbers of cars, numbers finishing on the lead lap, and number of DNFs

Car counts remained 50 and above throughout the 1950s, with one exception. The spring 1952 race featured the smallest field to start at Darlington with only 24 cars. Only 12 cars finished the race, two on the lead lap.

That level of attrition was common in Darlington’s early days. Out of the 75 cars starting the first Darlington race, 46 didn’t finish. Only the winner finished on the lead lap, with the second-place driver nine laps behind.

The attrition lessened over time, but slowly. The fall 1976 race was the first race in which more than 10% of the field finished on the lead lap. Twenty percent of the field finished on the lead lap in the fall 1986 race and the 30% mark was broken in fall of 1999.

These days, the percentage of cars finishing on the lead lap is usually between 40% and 60%. The largest percentage of cars to ever finish on the lead lap at Darlington is 65.1%, which happened in fall 2015.

But even though Darlington has mellowed, it sometimes shows a glimmer of its old self. Like the spring 2021 race, when a dominant Martin Truex Jr. led 248 of 293 laps and put all but nine of the 37 cars a lap down.

Corey LaJoie learning in his week with Chase Elliott’s team

Spending this week with Hendrick Motorsports has proved eye-opening for Corey LaJoie.

He will pilot Chase Elliott’s No. 9 car today at World Wide Technology Raceway after NASCAR suspended Elliott one race for wrecking Denny Hamlin during last week’s Coca-Cola 600. This gives LaJoie the chance to drive in the best equipment of his career.

Working with Elliott’s team also has given LaJoie an inside look as to what makes Hendrick Motorsports so successful.

“I thought that I knew what we didn’t have at Spire Motorsports, but I had no idea,” said LaJoie, who starts 30th after tagging the wall during his qualifying lap. “There’s tools that those guys have, intellectual properties specific to Hendrick Motorsports, that even some of the other teams don’t have.

“But the biggest thing that I noticed was just the people and the attitude of the pursuit of perfection. All the key partner teams across all the (manufacturers) all have the same data, but (Hendrick Motorsports has) an unbelievable way of delegating, taking, compacting and making it just digestible – whether it’s for a driver, an engineer, a crew chief.

“I think the fact that they have four incredibly strong teams individually raises the tide for those guys because when you’re sitting in the simulator and William Byron ran a 33.20 (seconds for a lap) … if you’re running a 33.35 with the same setup, you know you have a tenth-and-a-half under your butt and you have to go find it. And then when I go run a 33.20, William next time is going to want to run a 33.19.

“There’s always a consistently raised watermark on the driver’s end. There’s always a consistently raised watermark on the crew chiefs in trying to build the best setups, and the engineers trying to find the best strategies.

“The inner-team competition is one of the biggest things, and I think there are several teams that have that … the healthy ones are certainly evident. But it’s just the overall structure. We have a Hawkeye (camera-based inspection stations used by NASCAR at the track) … all the things that do the same stuff that Hendrick Motorsports has, but the depth of people, collective focus of the goal and the mission is noticeable and evident. It’s a different world.”

It would be easy for LaJoie to be overwhelmed in this situation. His career has been marked with underfunded rides and trying to make the most of his equipment. He’s having his best season in Cup this year. LaJoie ranks 19th in points heading into today’s race.

LaJoie acknowledges the opportunity he has, but he also can’t let it alter his focus.

“It’s been a wild week,” he said. “I can get all sentimental … (about) my dad subbing in for Ricky Craven in 1998 (for Hendrick Motorsports) and all that sort of stuff. But at the end of the day, when I sit in that thing, I don’t know that NAPA is on it, or the No. 9 is on it.

“I’m going to drive it like I have been driving the No. 7 Chevy and putting that thing 19th in points. It’s been a super fun, successful year so far, and we have a lot of work left to do and things to accomplish over there.”

When he returns to his Spire Motorsports ride after today’s race, LaJoie admits this weekend’s experience with Elliott’s team will help him with his own team.

“How I prepare, how I’m going to engage with my team at Spire Motorsports going forward is going to change,” LaJoie said. “I think I’m going to be able to come in there and just apply and share some of the things I’ve learned over the course of the week with (crew chief Ryan) Sparks and the No. 77 team, as well, and I think we’re all going to be stronger for it.”

Dr. Diandra: Is 2023 the season for a Ricky Stenhouse Jr. redemption?

0 Comments

Coming into 2022, Ricky Stenhouse Jr. had two career Cup Series wins in 364 starts. But both wins — and his career-high 13th-place season finish — happened back in 2017.

Stenhouse was unceremoniously dropped by Roush Fenway Racing in 2020 and landed with JTG Daugherty Racing. He made the news every now and then at a superspeedway but could be counted upon to head up season-ending lists of drivers involved in the most accidents. In the years Stenhouse hasn’t been at the top of the list, he’s been near the top.

DNFs and accidents have plagued Stenhouse throughout his NASCAR career. Jack Roush went so far as to park the Mississippi native in his early days in the Xfinity Series because he tore up so much equipment.

Stenhouse redeemed himself, going on to win two Xfinity championships.

From the way his 2023 season has started, it looks as though Stenhouse might be on a similar mission of redemption this year in the Cup Series.

Finishing races

Stenhouse started the 2023 season in the best possible way – winning the Daytona 500. But drivers from less-funded teams who win early superspeedway races usually settle to the bottom of the rankings by now.

Stenhouse hasn’t. He ranks 13th heading into Sunday’s race at World Wide Technology Raceway.

Standings aren’t as good a ruler this year as they usually are because of drivers missing races and teams incurring penalties. But Stenhouse’s statistics back up his ranking.

Stenhouse has finished every race this year on track, as opposed to in the garage or on the hook. Only Ryan Blaney and Corey LaJoie have achieved the same distinction.

In 11 of those 14 races, Stenhouse finished on the lead lap. That’s the same number of lead-lap finishes as William Byron. Denny Hamlin and Martin Truex Jr. are tied for most races finished on the lead lap with 13 each.

This time last year, Stenhouse had already racked up seven of the series-leading 18 caution-causing incidents he would be involved in for the season. Runner-up Chase Elliott had 15 incidents.

Going into Gateway this year, Stenhouse has been involved in only two accidents (Talladega and Charlotte) and had a tire go out at Darlington.

Approaching his career best

I compare three years in Stenhouse’s career in the table below: the 2017 season — his best to date — along with last year and the 14 races run so far this year.

A table comparing loop data stats for Ricky Stenhouse Jr. showing his path to redemption

Stenhouse’s current average finishing position of 13.5 ties with Christopher Bell for sixth best in the Cup Series. That’s 9.3 positions better than Stenhouse’s 2022 average. He’s even beating his 2017 average by 3.6 positions.

Qualifying results are down a bit from 2017 — but remember that those numbers are from the days when NASCAR allowed multiple practice sessions. Stenhouse is only two positions worse relative to 2017, but 7.6 positions better than last year when it comes to establishing his spot on the starting grid.

Stenhouse’s average running position is comparable to 2017 and 2.8 positions better than 2022. He ranks 20th among full-time Cup Series drivers in average running position. Although it’s an improvement, it’s still more than double William Byron’s series-leading 9.1 average running position this year.

More interesting is the difference between Stenhouse’s average running position his average finishing position. Some drivers run better than they finish. Stenhouse is doing the opposite.

In 2017, Stenhouse finished about 1.4 positions better than he ran. This year, he’s gaining an average of about five positions from where he runs.

One might argue this gain results from the plethora of late-race incidents this year that have removed drivers in the front of the field from contention. But Stenhouse deserves credit for putting himself in a position to benefit from those events.

Stenhouse’s green-flag speed rank is 11th among full-time Cup Series drivers. His 15.3 average, however, is 1.7 positions worse than 10th-place Kyle Busch. Still, it’s impressive that JTG Daugherty is right there in the mix with much better-funded teams. William Byron again has the best average green-flag speed rank at 7.9.

Consistently strong finishes

It’s not uncommon for a mid-pack driver to win a superspeedway race. But Stenhouse’s Daytona 500 win appears to be something more. The table below summarizes his wins and finishes for the same three years.

A table comparing finishes for 2017, 2022 and 2023 showing Ricky Stenhouse Jr's redemption attemptsThe difference between last year and this year is striking.

In 2022, Stenhouse finished in the top 20 in 12 of 36 races. He’s already matched that mark this year. He earns top-20 finishes 85.7% of the time in 2023 compared to 33.3% last year. Top-20 finishes aren’t the same as contending for a championship. But they’re a first step.

Stenhouse finished 2017 with nine top-10 races. With about 60% of the season remaining, he’s already earned five top-10 finishes this year.

What’s changed? The Next Gen car is one factor, but it didn’t make much difference for Stenhouse last year. I would point instead to Stenhouse’s reunion with Mike Kelley as his crew chief.

Kelley co-piloted both of Stenhouse’s Xfinity championships in 2011 and ’12. Although Kelley worked with Stenhouse and previous crew chief Brian Pattie since 2020, this is the first year Kelley is back up on the pit box.

Together, they’re basically halfway to matching Stenhouse’s best year.

And another step closer to redemption.

Custer went from fourth to first on the overtime restart when Parker Kligerman, who restarted third, attempted to pass Allgaier, who was leading. Sheldon Creed was on the outside of Allgaier. All three cars made contact entering Turn 1, allowing Custer to slip by. Creed finished seventh. Kligerman placed 14th.

Custer won the second stage when John Hunter Nemechek made contact with Creed’s car while racing for the lead on the final lap of the stage. The contact spun Creed and Custer inched by Nemechek at the line.

Early in the final stage, Creed gained revenge with contact that spun Nemechek, who went on to finish 10th. A few laps later, Nemechek and Joe Gibbs Racing teammate Sammy Smith had issues. Smith spun Nemechek. After getting back around, Nemechek quickly caught Smith and turned into Smith’s car, damaging it.

STAGE 1 WINNER: Sheldon Creed

STAGE 2 WINNER: Cole Custer

WHO HAD A GOOD RACE: Despite the contact on the overtime restart, runner-up Justin Allgaier managed to score his fourth consecutive top-three finish. … Sam Mayer’s third-place finish is his best on a road course. … Austin Hill’s fifth-place finish gives him four consecutive top-five results.

WHO HAD A BAD RACE: Daniel Hemric finished 33rd after a fire in his car. … Riley Herbst placed 32nd after an engine issue. After opening the season with six top 10s in a row, Herbst has gone seven races in a row without a top 10.
