Denny Hamlin — Winner: “First thing I did, I got out of the rig and I came up and watched the last six laps to kind of see what was going on. I can’t see everything when I’m sitting in the car, but certainly I was intrigued to see the last six laps and see what it looked like on TV. I thought it looked great. My first reaction 10 seconds in to watching it was like, I asked the people around me, I was like, ‘Do you believe this is not real.’ Like it looks so real. That part was really cool. … I wanted the bottom, and he was really, really smart to ‑‑ I mean, he didn’t win, but he was smart to kind of block the bottom there because the bottom lane at Homestead on iRacing just has tremendous more grip than what the lane I was running in, but I knew that the difference in the two lanes was about a tenth and a half to two tenths, and I thought my tires were about three tenths better.  So I thought as long as I got beside him, I was going to be able to complete it, even though he was in the preferred groove.”

Dale Earnhardt Jr. — Finished 2nd: “A lot of fun. Finished second. Got beat by Denny Hamlin, not the first time that he’s beat me on sim racing. The guy is pretty good. … A lot of guys put in a lot of work to get better in just a really short period of time. Denny doesn’t really race a lot but worked really hard this week to be able to be real competitive and it showed. A lot of the other guys did the same thing. … We took tires with 30 laps to and Denny took tires with about 20 laps to go and I think that was certainly a big advantage for him. We were racing really hard up front, too, burning our stuff up. I didn’t expect Denny to get up there and he did. Went to the bottom because if I go to the top he can pass me a whole lot easier. Plus, he wanted to, he could take the whole lane and knock me out of the way and I don’t even finish in the top five.”

Timmy Hill Finished 3rd“It was a really fun race. The top five did an excellent job all day long. I want to say thank you to NASCAR and iRacing for putting on this show. Today was a lot of fun. I did the best I could saving my tires at the end. We finally had our longest run of the day, 20 laps to the end. Didn’t take tires there and got beat. … I hope we get to do something like this again. These guys did a fantastic job with putting this race on. A lot of drivers put in a lot of time practicing.”

Chase Briscoe Finished 4th: “It was fun to get to do some type of racing, especially with the Cup guys and some others that I don’t get to race against a lot. Hopefully, it was a way for the fans to escape from everything that is going on and enjoy some good racing.”

Garrett Smithley Finished 5th: “Wow, that was fun, that was a lot of fun. I hope you guys enjoyed that. Cool deal. Started pole, finished fifth, led some laps. It was a good day. … It was a good day for the sim racing community. Cool to have some fun on these uncertain times but making the best of it. Hopefully we can get to the real racetrack soon.”

Alex Bowman Finished 6th:Heard the top 5 failed tech and I’ve been declared the official winner. I’d like to thank my sponsors, and most importantly my dog for taking over for a few laps.

Ryan Preece Finished 8th: My takeaways from today: iRacing is difficult. Easy to forget you’re on Live Video.”

Ty Majeski Finished 9th: “That was fun! P9 in the iRacing Pro Invitational. Got wrecked a couple of times and lost track position, had fun coming back up through the field!”

Erik Jones — Finished 10th: “Enjoyed myself more than I thought I would … Hope we get to do it again.”

Matt DiBenedetto — Finished 11th: My crew chief, aka myself, made a bad call at the end. I stayed out and then I was kind of a rolling roadblock on the older tires and fell to 11th.”

Landon Cassill — Finished 12th: “We had a good solid race. I got tore up at the beginning and had to use a reset. From that point it was just trying to get some green laps going. I let a lot of aggressive drivers by on restarts that ultimately ended up wrecking themselves.  That last restart with about 15 to go, there was a crash in front of me and I got through it, but I had to slow down enough that it gave like a two-second gap to the cars in front of me. Once I got going again, I just worked on my line, worked on kind of burning the right rear tire a little bit so I could wear the tires evenly and started picking them off very carefully and caught the field on the last lap.”

Parker Kligerman — Finished 13th: “Just stayed out on two tires there. Probably should have pitted with Denny, probably could have raced for the win but we didn’t have any more resets after getting involved in two wrecks there, one at the front and one trying to come up through the pack.”

Joey Logano — Finished 15th: “I don’t play on the reg and I struggled a bit throughout the race, but overall that was fun!”

Clint Bowyer — Finished 16th: “Guys, I let you down. Heck, I let myself down. I let my fans down. I had sponsors in the stands, praying for a good showing, and I end up wrecking our Mobil 1 Ford Mustang and using both redos, as a matter of fact. I think the real takeaway is, obviously, I need a lot more practice. With everything going on in the country right now, I hope the fans were satisfied and I hope they got their minds off of things for a little bit. We will be back. I will be better and, I promise you, if you get on iRacing and get online, you’re gonna see these boys, probably tonight, battling it out again.”

Ryan Truex — Finished 17th: “Not the day I wanted for the boys back at the shop. We will go back home and get to work on the cars and (come) back stronger.”

BOBBY LABONTE — Finished 18th:I didn’t use up all my credits for damage, so that was good. I hope it was awesome to watch. It was a lot of fun to do. We will get better at this, being this the first one. … That was a great way to spend a Sunday afternoon.”

Justin Allgaier — Finished 20th: “Had damage at the end that kept us from finishing higher up, but what a heck of a race and a killer finish!”

Ricky Stenhouse Jr. — Finished 21st: “That was interesting. heck of a race for the win that was cool to see. I definitely needed more than a night of practice for this #ProInvitationalSeries race. Had a lot of fun learning the sim world with @iRacing . We finished 21st with our @kroger chevy by missing all the wrecks.”

Austin Cindric — Finished 22nd: “Last 10 laps was watching the TV more than track! Looked like a great show by the end. Fun to do something new.”

Michael McDowell — Finished 23rd: “That was fun.”

Brad Keselowski — Finished 25th: I had a lot of fun, wrecked a lot. Congrats to Denny Hamlin. Great race for him. Drove to the front and won it, which is pretty cool with new tires. I tried to pit for new tires and be on the same strategy and got wrecked but that’s part of it. Hope you guys enjoyed.”

Austin Dillon — Finished 27th: “I didn’t do very well. We got up to the top 10. … We got some work to do. I’m going to practice this week for the next one. Hopefully this ties us over until we get to the real race track because I’m ready to go really racing. Thank you guys for all following it.”

Kyle Busch — Finished 29th: “We obviously didn’t qualify very good so we were kind of mired in the back. Guys were crashing and wrecking out and we were kind of moving our way up to the front. Restarted, I think 16th one time and was making up some positions and getting closer to the front and felt like we had a pretty good long-run speed that was going there, we were picking a couple of guys off and then a crash happened on the frontstretch … nowhere to go.”

Jimmie Johnson — Finished 31st: “Not a great showing. I’m going to take all the responsibility. I’ve not spent a lot of time in iRacing or really racing at all on sims. So I’m learning my way through that. Lots of things to learn within the race. I didn’t even have a spotter, which seemed to be a problem a couple of times with wrecks, race format, just a lot of race details.”

Anthony Alfredo — Finished 32nd: “I wish we didn’t have so many cautions, and I felt like I got caught up in just about every single one.  We used up both of our fast repairs, you were allowed two, by like 10 laps in. I was super cautious after that and made it all the way to the end and then I pitted with Denny Hamlin there from the top five, so we were on the same strategy and we were coming through the field and we got wrecked going into Turn 1 and I was out of fast repairs so couldn’t do anything.”

Kyle Larson — Finished 33rd: “Well that didn’t really work out. Hope everyone enjoyed watching though!”

William Byron — Finished 34th: “Really hope we continue doing this. I thought it was a lot of fun!

Kurt Busch — Finished 35th: What an experience. … Huge shoutout to David Gravel for letting me borrow his sim. I owe ya bro!”

Appeal panel gives William Byron his 25 points back

0 Comments

William Byron is back in a transfer spot after the National Motorsports Appeals Panel rescinded his 25-point penalty Thursday for spinning Denny Hamlin at Texas.

By getting those 25 points back, Byron enters Sunday’s elimination playoff race at the Charlotte Roval (2 p.m. ET on NBC) 14 points above the cutline.

Daniel Suarez is now in the final transfer spot to the Round of 8. He is 12 points ahead of Chase Briscoe and Austin Cindric. Christopher Bell is 45 points behind Suarez. Alex Bowman will not race this week as he continues to recover from concussion symptoms and has been eliminated from Cup title contention.

NASCAR did not penalize Byron after his incident with Hamlin because series officials did not see the contact. Two days later, NASCAR penalized Byron 25 points and fined him $50,000 for intentionally wrecking Hamlin.

The National Motorsports Appeals Panel stated that Byron violated the rule but amended the penalty to no loss of driver and owner points while increasing the fine to $100,000.

The panel did not give a reason for its decision. NASCAR cannot appeal the panel’s decision.

The panel consisted of Hunter Nickell, a former TV executive, Dale Pinilis, track operator of Bowman Gray Stadium and Kevin Whitaker, owner of Greenville-Pickens Speedway.

Here is the updated standings heading into Sunday’s race at the Roval:

Byron’s actions took place after the caution waved at Lap 269 for Martin Truex Jr.’s crash. As Hamlin slowed, Byron closed and hit him in the rear. 

Byron admitted after the race that the contact was intentional, although he didn’t mean to wreck Hamlin. Byron was upset with how Hamlin raced him on Lap 262. Byron felt Hamlin forced him into the wall as they exited Turn 2 side-by-side. Byron expressed his displeasure during the caution.

“I felt like he ran me out of race track off of (Turn) 2 and had really hard contact with the wall,” Byron said. “Felt like the toe link was definitely bent, luckily not fully broken. We were able to continue.

“A lot of times that kind of damage is going to ruin your race, especially that hard. I totally understand running somebody close and making a little bit of contact, but that was pretty massive.”

On the retaliatory hit, Byron said: “I didn’t mean to spin him out. That definitely wasn’t what I intended to do. I meant to bump him a little bit and show my displeasure and unfortunately, it happened the way it did. Obviously, when he was spinning out, I was like ‘I didn’t mean to do this,’ but I was definitely frustrated.”

Drivers for Drive for Diversity combine revealed

The 13 drivers who will participate in the Advance Auto Part Drive for Diversity Combine were revealed Thursday and range in age from 13-19.

The NASCAR Drive for Diversity Development Program was created in 2004 to develop and train ethnically diverse and female drivers both on and off the track. Cup drivers Bubba Wallace, Daniel Suarez and Kyle Larson came through the program.

The 2020 and 2021 combines were canceled due to the impact of COVID-19.

“We are thrilled that we are in a position to return to an in-person evaluation for this year’s Advance Auto Parts Drive for Diversity Combine,” Rev Racing CEO Max Seigel said in a statement. “We are energized by the high-level of participating athletes and look forward to building the best driver class for 2023. As an organization, we have never been more positioned for success and future growth.”

The youngest drivers are Quinn Davis and Nathan Lyons, who are both 13 years old.

The group includes 17-year-old Andrés Pérez de Lara, who finished seventh in his ARCA Menards Series debut in the Sept. 15 race at Bristol Motor Speedway.

Also among those invited to the combine is 15-year old Katie Hettinger, who will make her ARCA Menards Series West debut Oct.. 14 at the Las Vegas Bullring. She’s also scheduled to compete in the ARCA West season finale Nov. 4 at Phoenix Raceway.

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.

A graphic show shallower (low-angle) hits and deeper (high-angle) hits

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.

A graphic showing the five parts of the Next Gen chassis.

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.

NASCAR weekend schedule for Charlotte Motor Speedway Roval

NASCAR Cup Series drivers race on the road for the final time this season Sunday, as the Charlotte Motor Speedway Roval course ends the playoffs’ Round of 12.

The 17-turn, 2.28-mile course incorporating the CMS oval and infield will determine the eight drivers who will advance to the next round of the playoffs. Chase Elliott won last Sunday at Talladega Superspeedway and is the only driver who has qualified for a spot in the Round of 8.

Entering Sunday’s race, Austin Cindric, William Byron, Christopher Bell and Alex Bowman are below the playoff cutline. Bowman will not qualify for the next round because he is sidelined by concussion-like symptoms.

The race (2 p.m ET) will be broadcast by NBC.
