What drivers said after Sonoma race

1 Comment

Drivers had plenty to say after Sunday’s race at Sonoma Raceway. Here’s what they said:

Kevin Harvick — Winner: “To finally check this one off the list. I feel like we have been close a couple times but never put it all together. Being so close to home and having raced here so much, this was one that was on the top of the list and today we were able to check that box.”

Clint Bowyer — Finished 2nd: “You get there back in traffic and you’re so much faster than them, you have to check up to save a mistake. You run over them and you don’t mean to; you get frustrated and get a little bit farther behind and a little bit farther behind. I saw (Kyle Larson) check up and I get into him and I was thinking, ‘Well, we’ll both survive this’. And then all of a sudden (AJ Allmendinger) was coming through and I smoked him and hurt the left front. We were fast all weekend. With clean air and an long run, that’s always my strong suit. We got the long run, we just hard to start dead last to get it.”

Brad Keselowski — Finished 3rd: “We didn’t have the qualifying fun we wanted. We had amazing race pace. That’s a credit to everyone at Team Penske. It felt really good. I just wish I could run this race again I think I might have had better car than driver today and I learned a lot. Just an amazing fun day.”

Denny Hamlin — Finished 4th: “It was good, definitely had a great car. We didn’t have quite enough at the end. We did have real short run speed. We didn’t’ really have great long run speed. We had just had good middle speed and that worked out for us. We had good pit strategy and really passed a lot of cars today and that’s about what we had.”

Kurt Busch — Finished 7th: “I had a left-rear question, if it was going down or not. I went through four righthanders trying to make the call on if the left-rear was going to go down. I might have messed up a Stewart-Haas 1-2-3. I am happy for Kevin and Bowyer. We were about a third-place car. We were hanging with Denny (Hamlin) and Kyle (Busch) most of the day. I had to pit just to make sure with the tire. We went from 17th back up to seventh. It was a good charge at the end, just didn’t get that top five we wanted.’’

Chase Elliott – Finished 8th: “Just solid day. Good execution on pit road. Guys called great strategy and got us a decent finish.”

Ryan Blaney — Finished 9th: “It was pretty physical out there. We had a long green-flag run there at the end. There were some different strategies and we kind of played to the side of if there was a caution at the end we would be in a good spot. That is why we had some of the oldest tires out there. We were still able to make moves and pass some cars. I think we ended up ninth, so that is a good day for us. It is good to end up about where we should have. Where we deserved. A big improvement from last year so that is nice.”

Jamie McMurray – Finished 10th: “I thought we were going to be fourth or fifth and some of those guys pitted and actually ran us back down with tires, which you normally don’t see. We normally don’t have that long of a green flag run, but overall really good day.”

Paul Menard – Finished 11th: “The guys on this Tarkett/Menards Chevrolet did a solid job working on our car all weekend. It handled well all day and we battled inside the top 10 for much of the race. We knew pit strategy would come into play today and Matt Borland called a great race from the drop of the green flag. We gambled by coming to pit road late and hoping on a caution, but never got one. If we had about three more laps with those fresh tires, we probably could have fought our way into the top 10.”

Joey Logano — Finished 12th: “We had a pretty good car and made adjustments to make it better, probably a top-five car once we had it going but I sped down pit road. We had the winning strategy and scored a lot of stage points. With a little more speed we maybe could have won the thing. I just sped down pit road and lost so much track position after that. That one stings a little bit.”

Jimmie Johnson – Finished 13th: “I had no earthly idea what was going on. I passed so many cars. I don’t even know what strategy won.  It was very difficult to know what was going on from inside the car. I would assume that caused a lot of great viewing and entertainment that was fun to watch, but I had no clue what was going on out there.”

Ryan Newman – Finished 15th: “It was good to see us run up in the top 10 and earn valuable stage points today in our Chevrolet Accessories car. We started off really loose in Turn 10 and lost some ground but once we had a chance to fine-tune it, we were pretty decent. We thought there might be a chance to gain spots at the end by just staying out because we were good on fuel, but it didn’t work out in our favor. With about 20 to go, our tires were pretty much cooked so we just stayed the course and hoped for the best. I had a lot of fun road course racing. I just wish we could have had a better finish. This 31 team did a good job for me and I appreciate Chevrolet coming along for the ride.”

Danica Patrick – Finished 17th: “It definitely wasn’t the day the Code 3 Associates team was expecting, but we were able to battle back to a decent finish. The car was just awful in the final laps of the last two runs, but we made the most of it at the end.”

Austin Dillon – Finished 18th: “The team gave me a great Dow Coatings Material Chevy all weekend and I feel bad for what happened there in the closing laps. We qualified 19th, which was my career-best start at Sonoma Raceway. We raced our way into the top 10 and collected stage points in the first two stages.  After the spin in Turn 11, I had no rear grip the rest of the way. I’m bummed that it happened but I can’t say enough about this entire No. 3 team. It was a lot of fun out there.”

Kasey Kahne — Finished 24th: “It was a hard hit. No. 15 (Kevin O’Connell), no clue who he is, I saw him a lot today lapping him, but he went low down the front stretch and then just, I was going to his outside and he just turned right and just hit me, put me straight in the wall getting the white flag there. No clue what he was thinking. You obviously don’t know what he’s doing either. But we had a better car the longer the day went. Just really tight early and the guys kept working on it and we got better and better. I have no clue where we were running, but we were definitely much better at the end than we were at the start and passed some cars later on.”

Erik Jones — Finished 25th: “It was a long day. You know, learning all day and come home with a top 25 is all we really wanted to do.’’

Trevor Bayne – Finished 27th: “We showed we had speed with our AdvoCare Ford today. Every time we could really get going the temps would unfortunately keep getting hotter and hotter which is why we had to come down pit road during that final stage. I hate that we didn’t get the result we deserved but we will rebound form this next week at Daytona where anything can happen and I hope to be out front when it’s all said and done.”

AJ ALLMENDINGER — Finished 35th: “I don’t know what happened there. I just noticed what was going to be our final pit stop I kind of looked down and just noticed the battery starting to die. From there that was it. Shutting all the switches off and everything wasn’t going to work. I’m mad at myself for not driving very well. The car was pretty good.  That first stint was good. The No. 78 (Martin Truex) was pretty good, but thought we were going to be okay. I just didn’t drive very well and just bad luck again.”

MARTIN TRUEX JR — Finished 37th: “After we made that last pit stop, when we lost the lead to (Kevin) Harvick, soon as I left pit road, I lost a cylinder. I was surprised we were able to keep up with them as well as we could on seven, but just shows how strong the car was. Just wasn’t meant to be today.”

RICKY STENHOUSE JR — Finished 38th: “They were three-wide in front of us trying to go through Turn 4 which never works. They were all dive-bombing each other and then (Danica Patrick) got spinning and I tried to go low and she just kept coming down the track. We just clipped it a little bit and tore the left front up too bad to continue. It is a bummer for our day. We felt like we had probably a decent Sonoma car for us. Really just wanted to get out there and make laps. I thought we were decent on the long run, just trying to get there.”

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

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.

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.

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.
