It’s once again almost time for the annual Throwback Weekend at Darlington Raceway that is capped off by the Sept. 3 Southern 500 on NBCSN.

That means what was once old is new again and that goes with the latest parade of retro paint schemes.

Here’s your guide to all the paint schemes that will be driven in the Southern 500.

This post will be updated.

Brad Keselowski – Keselowski will pilot the “Midnight” paint scheme Rusty Wallace made famous in the mid-90s during his time in Team Penske’s No. 2 car. This isn’t the first time Keselowski has driven this look. It was on his No. 2 Ford in August 2015 at Michigan.

Austin Dillon – This year marks the 30th anniversary of Dale Earnhardt’s 1987 win in the Southern 500. Richard Childress Racing is honoring that achievement by putting Earnhardt’s Wrangler paint scheme from that year on Austin Dillon’s No. 3 Chevrolet and Ryan Newman‘s No. 31 Chevrolet.

Kevin Harvick – The No. 4 Busch Chevrolet will have a paint scheme that is based on the “Head for the mountains” commercials from the 1980s. Harvick won the 2014 Southern 500.

Kasey Kahne  Kahne’s No. 5 Chevrolet will pay tribute to Geoffrey Bodine, the first driver to win for Hendrick Motorsports in the Cup Series. The paint scheme is the same one Bodine had on the No. 5 in 1985 when it was sponsored by Levi Garrett.

Danica Patrick – The No. 10 Ford will have the paint scheme that Dale Jarrett used in his 1999 Cup Series championship year when he drove for Robert Yates Racing. Patrick will also be sponsored by Ford Credit, which was a sponsor on Jarrett’s No. 88 Ford that season.

Ty Dillon – Germain Racing’s No. 13 Chevrolet looks similar to the way it did in last season’s Southern 500. The car will yet again have a paint scheme that Smokey Yunick once used on the No. 13 car he owned in the 1960s.

Clint Bowyer – Bowyer’s No. 14 Ford will have the sponsor and paint scheme that NASCAR Hall of Famer Mark Martin drove in the Xfinity Series from 1988-1991. All three of the Southern 500 Throwback Weekends have featured Martin paint schemes.

 

Ryan Blaney – The Wood Brothers Racing car will have the same look as it did in 1987 when Kyle Petty drove for the team. That year Petty won the Coca-Cola 600 for one of his eight Cup victories.

Joey Logano – The No. 22 Ford will bear the paint scheme used by Jimmy Vasser in IndyCar in 2002, the year Shell and Pennzoil merged.

Team Penske

Corey LaJoie – The No. 23 Toyota will pay tribute to Davey Allison. LaJoie’s paint scheme will be the one used by Allison in 1984 when he drove a No. 23 Miller High Life Pontiac in the Busch Series (now Xfinity Series).

NASCAR

 

Chase Elliott – The Hendrick Motorsports’ driver will drive the light blue paint scheme his father Bill Elliott had in his first Cup start on Feb. 29, 1976 at Rockingham Speedway.

Ryan Newman – Like Austin Dillon, Newman’s No. 31 Chevrolet will evoke Dale Earnhardt’s 1987 Wrangler paint scheme.

Matt DiBenedetto – The Go Fas Racing driver will have the scheme used by Bobby Allison in 1988 when he won the Daytona 500 for his 84th and final NASCAR Cup Series victory.

Aric Almirola – Four months after Almirola was born in March 1984, Richard Petty won his 200th and final Cup race in the July 4 Firecracker 400 at Daytona. Almirola will sport the same paint scheme “The King” took to victory lane that day.

AJ Allmendinger – The JTG Daugherty Racing driver will have the paint scheme Terry Labonte drove in 1986 when his No. 44 car was sponsored by Piedmont Airlines.

Jimmie Johnson – The paint scheme for the No. 48 Lowe’s Chevrolet is inspired by the trucks Lowe’s used in 1986.

Hendrick Motorsports

Derrike Cope – The 1990 Daytona 500 winner will have his own throwback for the Southern 500. Cope will have his paint scheme and sponsor from the 1994 Cup season when he drove the Mane ‘n Tail No. 12 car for Bobby Allison Motorsports.

Dale Earnhardt Jr.  – In his final Southern 500 start, Earnhardt’s No. 88 Chevrolet will bear the paint scheme Earnhardt used during his two championship seasons in the Xfinity Series in 1998-99. Earnhardt drove the No. 3 AC Declo car for Dale Earnhardt Inc., winning 13 over the course of the two seasons.

Michael McDowell – The No. 95 Chevrolet, owned by Leavine Family Racing, will bear the paint scheme 1992 Cup champion Alan Kulwicki drove in his Rookie of the Year season in 1986. LFR operates out of the same shop Kulwicki did until his death in a 1993 plane crash.

Other Throwback Weekend paint schemes:

Kevin Harvick (Xfinity) – Harvick will drive the original Hunt Brothers Pizza paint scheme that was first used in 2008 by Ken Schrader.

Matt Tifft (Xfinity) – The Joe Gibbs Racing driver will honor Dale Earnhardt Sr., driving the paint scheme Earnahrdt used in one race in 1977 when he drove the No. 19 car at Charlotte Motor Speedway.

Erik Jones (Xfinity) – Jones will pay tribute to Davey Allison with his 1988 rookie paint scheme.

Jeremy Clements (Xfinity) – The No. 51 car will pay tribute to A.J. Foyt and his 1964 win in the Firecracker 400 at Daytona. Clements’ grandfather, Crawford, served as Foyt’s crew chief for the race.

Brad Keselowski Racing (Camping World Truck Series) – The two trucks owned by BKR, the No. 19 driven by Austin Cindric and the No. 29 of Chase Briscoe, will have paint schemes dedicated to the Keselowski family’s racing history for the Sept. 3 race at Canadian Tire Motorsport Park.

Austin Cindric – The purple and white paint scheme was used on cars driven by Keselowski’s uncle, Ron Keselowski, in both USAC and the Monster Energy NASCAR Cup Series. From 1970-74, he earned 11 top-10 finishes in 68 starts as a driver, including a pair of fifth-place finishes in back-to-back seasons at Michigan International Speedway.

Chase Briscoe – The No. 29 truck will bear the paint scheme driven by Brad Keselowski’s father, Bob, to victory lane in 1997 at Richmond. It was his only win in 86 Truck series starts.

Dr. Diandra: Crashes: Causes and complications

0 Comments

Two drivers have missed races this year after hard rear-end crashes. Kurt Busch has been out since an incident in qualifying at Pocono in July. Alex Bowman backed hard into a wall at Texas and will miss Sunday’s race at the Charlotte Roval (2 p.m. ET, NBC).

Other drivers have noted that the hits they’ve taken in the Next Gen car are among the hardest they’ve felt in a Cup car.

“When I crashed it (at Auto Club Speedway in practice), I thought the car was destroyed, and it barely backed the bumper off. It just felt like somebody hit you with a hammer,” Kevin Harvick told NBC Sports.

The three most crucial parameters in determining the severity of a crash are:

  • How much kinetic energy the car carries
  • How long the collision takes
  • The angle at which the car hits

Angle

The last of these factors requires trigonometry to explain properly. You can probably intuit, however, that a shallower hit is preferable to a head-on — or rear-on — hit.

When the angle between the car and the wall is small, most of the driver’s momentum starts and remains in the direction parallel to the wall. The car experiences a small change in velocity.

The larger the angle, the larger the change in perpendicular speed and the more force experienced. NASCAR has noted that more crashes this season have had greater angles than in the past.

Busch and Bowman both had pretty large-angle hits, so we’ll skip the trig.

Energy — in pounds of TNT

A car’s kinetic energy depends on how much it weighs and how fast it’s going. But the relationship between kinetic energy and speed is not linear: It’s quadratic. That means going twice as fast gives you four times more kinetic energy.

The graph shows the kinetic energies of different kinds of race cars at different speeds. To give you an idea of how much energy we’re talking about, I expressed the kinetic energy in terms of equivalent pounds of TNT.

A vertical bar graph showing kinetic energies for different types of racecars and their energies

  • A Next Gen car going 180 mph has the same kinetic energy as is stored in almost three pounds of TNT.
  • Because IndyCars are about half the weight of NASCAR’s Next Gen car, an IndyCar has about half the kinetic energy of a Next Gen car when both travel at the same speed.
  • At 330 mph, Top Fuel drag racers carry the equivalent of six pounds of TNT in kinetic energy.

All of a car’s kinetic energy must be transformed to other types of energy when the car slows or stops. NASCAR states that more crashes are occurring at higher closing speeds, which means more kinetic energy.

Longer collisions > shorter collisions

That seems counterintuitive, doesn’t it? Who wants to be in a crash any longer than necessary?

But the longer a collision takes, the more time there is to transform kinetic energy.

A pitting car starts slowing down well below it reaches its pit box. The car’s kinetic energy is transformed into heat energy (brakes and rotors warming), light energy (glowing rotors), and even sound energy (tires squealing).

The same amount of kinetic energy must be transformed in a collision — but much faster. In addition to heat, light and sound, energy is transformed via the car spinning and parts deforming or breaking. (This video about Michael McDowell’s 2008 Texas qualifying crash goes into more detail.)

The force a collision produces depends on how long the car takes to stop. Compare the force from your seat belt when you slow down at a stop sign to what you feel if you have to suddenly slam on the brakes.

To give you an idea of how fast collisions can be, the initial wall impact in the crash that killed Dale Earnhardt Sr. lasted only eight-hundredths (0.08) of a second.

SAFER barriers use a car’s kinetic energy to move a heavy steel wall and crush pieces of energy-absorbing foam. That extracts energy from the car, plus the barrier extends the collision time.

The disadvantage is that a car with lower kinetic energy won’t move the barrier. Then it’s just like running into a solid wall.

That’s the same problem the Next Gen car seems to have.

Chassis stiffness: A Goldilocks problem

The Next Gen chassis is a five-piece, bolt-together car skeleton, as shown below.

The purple is energy-absorbing foam. Graphic courtesy of NASCAR. Click for a larger view.

That graphic doesn’t show another important safety feature: the energy absorbing foam that covers the outside of the bumpers. It’s purple in the next diagram.

All cars are designed so that the strongest part of the car surrounds the occupants. Race cars are no different.

The center section of the Next Gen chassis is made from stout steel tubing and sheet metal. Components become progressively weaker as you move away from the cockpit. The bumper, for example, is made of aluminum alloy rather than steel. The goal is transforming all the kinetic energy before it reaches the driver.

Because the Next Gen car issues are with rear impacts, I’ve expanded and highlighted the last two pieces of the chassis.

The rear clip and bumper, with the fuel cell and struts shaded

The bumper and the rear clip don’t break easily enough. The rear ends of Gen-6 cars were much more damaged than the Next Gen car after similar impacts.

If your initial thought is “Just weaken the struts,” you’ve got good instincts. However, there are two challenges.

I highlighted the first one in red: the fuel cell. About the only thing worse than a hard collision is a hard collision and a fire.

The other challenge is that a chassis is a holistic structure: It’s not like each piece does one thing independent of all the other pieces. Changing one element to help soften rear collisions might make other types of collisions harder.

Chassis are so complex that engineers must use finite-element-analysis computer programs to predict their behavior. These programs are analogous to (and just as complicated as) the computational fluid dynamics programs aerodynamicists use.

Progress takes time

An under-discussed complication was noted by John Patalak, managing director of safety engineering for NASCAR. He told NBC Sports’ Dustin Long in July that he was surprised by the rear-end crash stiffness.

The Next Gen car’s crash data looked similar to that from the Gen-6 car, but the data didn’t match the drivers’ experiences. Before addressing the car, his team had to understand the disparity in the two sets of data.

They performed a real-world crash test on a new configuration Wednesday. These tests are complex and expensive: You don’t do them until you’re pretty confident what you’ve changed will make a significant difference.

But even if the test goes exactly as predicted, they aren’t done.

Safety is a moving target.

And always will be.

Rodney Childers fined $100,000, suspended for four races

0 Comments

NASCAR has suspended Rodney Childers, Kevin Harvick‘s crew chief, for four races and fined him $100,000 for what the sanctioning body called modification of a part supplied by a vendor.

Harvick, who is out of the Cup Series playoffs, and the Stewart-Haas Racing No. 4 team were docked 100 points.

Harvick’s car and that of Martin Truex Jr. were taken to NASCAR’s Research and Development Center in Concord, N.C. after last Sunday’s race at Talladega Superspeedway. There were no penalties assessed to the Truex team.

Harvick has been particularly critical of the Next Gen car in recent months, once referring to the “crappy-ass parts” provided by suppliers.

Harvick’s car erupted in flames during the Southern 500 Sept. 4 at Darlington Raceway. After he climbed from the smoking car, Harvick blamed the fire on “just crappy parts on the race car like we’ve seen so many times. They haven’t fixed anything. It’s kind of like the safety stuff. We just let it keep going and keep going.

“The car started burning and as it burned the flames started coming through the dash. I ran a couple laps and then as the flame got bigger it started burning stuff up and I think right there you see all the brake fluid that was probably coming out the brakes and part of the brake line, but the fire was coming through the dash.

“What a disaster for no reason. We didn’t touch the wall. We didn’t touch a car, and here we are in the pits with a burned-up car, and we can’t finish the race during the playoffs because of crappy-ass parts.”

Unless the team appeals, Childers would miss races at Charlotte, Las Vegas, Homestead and Martinsville and would return for the season finale at Phoenix.

NASCAR president Steve Phelps told the Associated Press that officials have not targeted Harvick. “I would say that’s ridiculous,” he said. “No one has a vendetta against Kevin Harvick or Rodney or anyone at Stewart-Haas Racing.”

On Wednesday afternoon, Harvick tweeted, “Seems strange…” A Childers tweet called the penalty “Shocker…..”.

NASCAR also announced Wednesday it has suspended Young’s Motorsports crew chief Andrew Abbott indefinitely for a behavioral violation during pre-race inspection. He must undergo anger-management training to be reinstated. The team races in the Camping World Truck Series.

Drivers to watch in NASCAR Cup Series race at Charlotte Roval

0 Comments

The lineup for the NASCAR Cup Series playoffs Round of 8 will be decided in Sunday’s race at the Charlotte Motor Speedway Roval.

Entering the race, the final event in the Round of 12, Austin Cindric, William Byron, Christopher Bell and Alex Bowman are below the cutline. Bowman will miss the race — and thus the cutoff — as he continues to battle concussion-like symptoms. Noah Gragson is scheduled to drive the No. 48 Chevrolet Sunday.

Cindric is tied with Chase Briscoe for the eighth playoff spot, but Briscoe would claim it on the tiebreaker. Byron is 11 points back, and Bell is 33. Hendrick Motorsports has appealed the penalty to Byron that dropped him below the cutline. That appeal is scheduled to be heard Thursday.

Any playoff driver who wins Sunday’s race and isn’t already qualified — Chase Elliott qualified for the Round of 8 by winning last week at Talladega Superspeedway — automatically advances to the Round of 8.

Drivers to watch Sunday at the Roval (2 p.m., ET, NBC), the final road-course race of the season:

FRONTRUNNERS

Chase Elliott

  • Points position: 1st
  • Last three races: Won at Talladega, 32nd at Texas, 2nd at Bristol
  • Past at CMS Roval: Won in 2019 and 2020

Elliott is the clear favorite to win a second championship. He won Sunday at Talladega to advance to the Round of 8 and can relax Sunday at Charlotte having punched his ticket. Relaxing isn’t likely, however, as Elliott will be among the favorites to win.

Ryan Blaney

  • Points position: 2nd
  • Last three races: 2nd at Talladega, 4th at Texas, 30th at Bristol
  • Past at CMS Roval: Won in 2018.

Blaney continues along a path that could result in him winning the Cup championship without winning a race. He came within an eyelash of winning Sunday at Talladega but fell victim to Chase Elliott’s last-lap charge. He should be a threat Sunday at the Roval, where he has four straight top 10s.

Kyle Larson

  • Points position: 6th
  • Last three races: 18th at Talladega, 9th at Texas, 5th at Bristol
  • Past at CMS Roval: Won in 2021

Larson’s last win — and his last top-four finish — came at Watkins Glen seven races ago. He is 18 points over the cutline entering Sunday’s race.

QUESTIONS TO ANSWER

Austin Cindric

  • Points position: 9th
  • Last three races: 9th at Talladega, 15th at Texas, 20th at Bristol
  • Past at CMS Roval: Sunday will mark his first Cup race. Has three top threes in four Xfinity starts.

Cindric hasn’t won since the season-opening Daytona 500 and is one of five drivers still in the playoffs who own only one victory this year. His ninth-place run at Talladega ended a streak of four straight finishes of 12th or worse.

Daniel Suarez

  • Points position: 7th
  • Last three races: 8th at Talladega, 12th at Texas, 19th at Bristol
  • Past at CMS Roval: Best finish in four starts is 13th

Suarez is 12 points above the cutline entering Sunday’s race. He has never led a lap at the Roval and has never finished in the top 10.

Chase Briscoe

  • Points position: 8th
  • Last three races: 10th at Talladega, 5th at Texas, 14th at Bristol
  • Past at CMS Roval: Finished 22nd last year in his only Cup start

Briscoe is teetering on top of the cutline in search of a spot in the Round of 8. He hasn’t won since the fourth race of the year at Phoenix and had a poor performance at the Roval last year.
