What drivers said after Saturday’s Michigan Cup race

0 Comments

Here is what drivers said after the race Saturday at Michigan:

Kevin Harvick — Winner:  “Anytime we come to Michigan since I’ve been at Stewart‑Haas Racing these cars have been just lightning fast. It’s definitely a place we feel like we should come up here and contend for the win, and today our Busch Light Apple Ford Mustang was just on rails, could go bottom, top, middle, was fast down the straightaway, would do everything that you wanted to do. Just got challenged by a whole bunch of restarts at the end that made it kind of crazy. But in the end it was a great day for us. Everybody did a great job, called a great race, and we capitalized on a fast car and put it in Victory Lane.”

Brad Keselowski — Finished 2nd: “(Kevin Harvick) is just super fast in the corners and the straightaway. He was definitely the best car out here today. We put a good effort to kind of maximize our day and that is what we did, finished second. Proud of everyone on the Discount Tire Ford Mustang team. We will go back to work on it and hopefully find a little bit more for the race (Sunday).”

Martin Truex Jr. — Finished 3rd: “It was a good day. I just made a little mistake there and barely rubbed (Tyler Reddick’s) car off (Turn) 2 there and I guess cut both of our tires down. I really don’t know how it happened. My bad on that one. I hate it for Tyler, it messed up his day early as well. We just fought back. The Auto Owners Camry was really strong. If we could ever have gotten to the front, I think we would have had something for them. Lots of restarts and they’re crazy here. A couple of them didn’t work out. The last one did. Really good car and really good job by the guys coming back like that. Just need a little bit more.”

Ryan Blaney — Finished 4th: “I thought our Mustang was pretty good all day. We made a good call there before the competition caution to come in and pit and that cycled us up to 12th or something and we were able to drive to third before that stage and then ran second in the second stage. We took four tires there when we got in our fuel window and it was hard to get through traffic. We didn’t handle good so we came in again with maybe 18 to go and changed it up a little bit and made sure we were good on gas and were able to drive through there. I wish we would have kept third before that last caution because I would have chose the bottom and had a little better shot. I am proud of the effort. (Kevin Harvick) was really fast. We need to work on our stuff a little and I think we can compete a little better tomorrow.”

Kyle Busch — Finished 5th: “The car was pretty good right off the bat. There’s still some things we can tweak on, hopefully. I’m scared to mess with it to try to make it better. It was just really, really hard to deal with in traffic. Anytime there was anybody in front of me, I had to be away from them, whether lower or higher, but not follow. It would not track at all with the car in front of me. That’s kind of been our ‘MO’ actually. Overall, just work on that.”

Denny Hamlin — Finished 6th: “I thought we were kind of a second-place car. Once (Kevin Harvick) was leading there, we were able to stay pretty close to him. He was just so much faster down the straightaway than we were. I’m not sure that we would have been able to do much with him. We were certainly fast in the corners and we were just kind of a second-place car. My crew chief (Chris Gabehart) was concerned about loose lug nuts there around Lap 130 when the caution came out so he wanted to come and take tires and work on the car and make sure the lug nuts were tight. That set us back and put us probably 11th or 12th in line. We could only muster coming back to sixth.”

Chase Elliott — Finished 7th: “We had a strong restart there at the end of the race from the inside lane. When that next caution came out, I just didn’t see it playing out the same way twice, so I chose to go to outside lane. Our NAPA Chevrolet was just tight all day and the team worked hard to try and get it dialed in – they had a solid day on pit road. I think we learned a few things today that we can hopefully use (Sunday).”

Joey Logano — Finished 8th: “It was a good recovery. A little bit of practice this week would have been nice. That was one of the loosest and out of control race cars I have had. At the start of this race. The clean air made us look better than what we were. As soon as I lost clean air I was just trying to hang on. Unfortunately I collected a lot of damage along the way on the back bumper from everyone hitting me. I don’t blame them, I was in the way. Over time, by probably the beginning of the third stage we got close. Not quite to where we needed to. Then there at the end we pitted and may have gotten to the other side of it finally. At least we know where the edge is so we can work on it for (Sunday). We got a top 10 out of it. If you had told me we were going to finish eighth after the first 50 laps of this thing I would have taken it but greed always sets in and you want a little more there at the end. We got our Mustang for tomorrow and we got to the other side of it. We should be in the ballpark.”

Bubba Wallace — Finished 9th: “A solid day for us and our Victory Junction Chevrolet. I appreciate everybody back at the shop. I know this whole COVID-19 deal has been tough. I haven’t been able to go to the shop and show my appreciation and how much they really work and make our cars better week in, and week out. So, it’s been fun. We’re in the middle of ‘silly season’ right now, so my mind is there, it’s here. So, to come out with a solid top-10 finish is positive.”

Kurt Busch — Finished 10th: “With a shorter race we had a bunch of variables today, including a lot of restarts. When the spotter says, four and five-wide, and we didn’t get damage, I will take that any day. Our Monster Energy Camaro was really reliant on clean air, once we got back in traffic it was really a struggle for us, but we were able score points in the first two stages and battle back for another top-10 finish at the end. We know that we can do better, and we’ll get a chance to do that (Sunday).”

Jimmie Johnson — Finished 12th: “We had a fast Ally Chevy all day, but restarts hurt us. It was up and down all day fighting traffic and weird things happening on the restarts. We are going to talk tonight and get a better plan for (Sunday). It’s a long day for these team guys but we will be ready.”

William Byron — Finished 14th: “It was a tough day for our No. 24 Axalta team. We worked hard to improve the handling of our Axalta Chevy as the day went on. Luckily we’ll get another chance at it (Sunday) and we’ll hopefully get a better result and stay in the playoff hunt.”

Aric Almirola — Finished 16th: “That wasn’t the day we hoped for, but we learned a lot about the way we set up our cars as a team. Proud of Stewart-Haas Racing and congrats to Kevin (Harvick) for bringing home the win. We’re going to take a big swing at it tomorrow and hope to build on that.”

TYLER REDDICK — Finished 18th: “We had some good speed in our No. 8 Chevrolet Accessories Camaro today at Michigan International Speedway, but we just seemed to get caught up in other people’s messes today. I was able to move up into the top 10 early in the race, but (Martin Truex Jr.) made contact with us when he had a tire go down, which gave our Chevrolet some left rear damage. It felt like we had a tire going down shortly after that, so we were forced to pit under green for fresh left-side tires. We had to fight hard to get our lap back and did, but then our right-rear tire went down and we had to pit to repair that under green as well. Somewhat luckily for us, that tire issue happened close to the end of Stage 2, so we were able to get our lap back with the wave around, stay mostly on sequence with the leaders and really get back in the game. We were making some progress after that and were up inside the top 20 when we got some additional right front damage from another on-track incident, so we had to hit pit road one more time for slight repairs but didn’t lose a lap. We were able to avoid a couple late-race accidents to pick up a few more spots but didn’t quite get to where we wanted to be today. Good news is that we get another shot at it with our No. 8 Chevrolet Accessories Camaro (Sunday).”

Clint Bowyer — Finished 19th: “We got back in traffic in the final stage and were really loose. You don’t want to be in the back at this place, it was like gridlock. We ran well early, got some positions in overtime today and we start second (Sunday) so I’m optimistic.”

Daniel Suarez — Finished 24th: “I was pretty happy with the way our Toyota was handling during the second half of the race, especially on the longer runs. Good job by Dave (Winson, crew chief) and all the guys. We’re still lacking the overall speed we need to be more competitive. That will come. We have work to do to make things better for (Sunday). One good thing is we will have a much better starting position (24th) than we usually have, so hopefully we can take advantage of that and have a really good finish.”

Michael McDowell — Finished 29th: “It was a difficult day for our No. 34 Love’s Travel Stops, Martin Transportation Systems (MTS) Ford Mustang. We didn’t fire off like we had hoped, but (crew chief Drew Blickensderfer) and the team did a nice job of working on the car all race long and I felt like we had a pretty decent run starting towards the end. Unfortunately we got collected in that last wreck and sustained heavy right front damage and we had to pit for repairs and ultimately brought the car home 29th. But tomorrow’s another day and that’s what we’re focused on. I’m ready to get back behind the wheel for race two of the Michigan doubleheader weekend and score Love’s Travel Stops and MTS a solid finish.”

Austin Dillon — Finished 31st: “Well, not the result we were hoping for today at Michigan International Speedway, but the good news is we have another shot at it (Sunday) afternoon. We started off too free but once (crew chief) Justin Alexander and the team were able to tighten up the No. 3 Dow MobilityScience Chevrolet Camaro ZL1 we were really good. At the end of the race, we were loose, sliding around four-wide when another car ran us over from behind. It ruined our top-10 finish. We’ll pull the backup out and go get them (Sunday).”

Cole Custer — Finished 34th: “It was a tough end to the day for us. We had a pretty good car and made good adjustments throughout the day. There at the end we just got in dirty air and it was hard to pass. Our HaasTooling.com/Jacob Construction Ford Mustang was good but track position and clean air were so important.”

John Hunter Nemechek — Finished 36th: “It was a long, tough day at Michigan International Speedway for our No. 38 Death Wish Coffee Ford Mustang. We actually weren’t too bad to start off, just needed to be a tick freer at the beginning. Unfortunately, we had some contact with (Chris Buescher), which sent us into the grass and then we had multiple tires go down, which ended our day prematurely. Appreciate all the hard work my crew has put into our cars this weekend and all the support from our partners. Thankfully, we’ll have another chance in tomorrow’s race.”

Drivers for Drive for Diversity combine revealed

0 Comments

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.

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.
