What drivers said after Cup playoff race at Miami

1 Comment

Joey Logano — Winner: “No, I told you we weren’t and showed you why were not (the underdog). We were the favorite like I told you before the race started. I am so proud of everybody for rising to the occasion. We executed down the stretch like nobody’s business. … I can’t wait to break that Mustang out.”

Martin Truex Jr. — Finished 2nd: “I just needed time. That’s all I needed. They were faster than us for 15 or 20 laps all day long. It was like a reverse scenario from last year. Last year we took advantage of the short run car at the end – the 18 (Kyle Busch) car should’ve won the race and tonight we should’ve won the race and they (Joey Logano) took advantage of the short-run car. I don’t know what else we could’ve done. Honestly, we worked our guts out all weekend and just to get here, I told you earlier we shut a lot of people up and made them eat crow and that felt good. To come here and almost upset the field and almost win it back to back was really awesome. I just wish that last caution hadn’t come out. Other than that, I don’t know what we could’ve done.”

Kevin Harvick — Finished 3rd: “Obviously, we got loose as the night went on. Really, it was a great pit call there in position to win the race if the caution doesn’t come out and we came down to a pit stop and a restart and we didn’t do either good. I just hate it for all our guys on our Jimmy John’s Ford.”

Kyle Busch — Finished 4th: “Just not at all what we wanted obviously and not what we expected either. We knew the 22 (Joey Logano) was fast, but man, I thought we were way closer than that. We kind of held up the first half of the race, but after that we were just never close. I don’t know what happened, just didn’t have the feel in the race car that I needed tonight. Just all night long, as soon as we got out of the gas and into the corner we were just sideways, just turning to the right and trying to save it. You do that for 50 or 60 laps, whatever it is on tires and you just can’t hang on. I couldn’t hang after eight laps, let alone the 50. Bummed for all of our guys, Adam Stevens (crew chief) and my guys did a phenomenal job. This M&M’s Camry team was really, really good – just not good enough on the night we wanted the most. We finished fourth, last of the Playoff guys. That’s not what it takes these days.

Chase Elliott — Finished 7th: “Man, if we make this (Championship) 4 one day, we’ve got a lot of work to do.”

Clint Bowyer — Finished 8th: “I want to congratulate everyone at Ford Performance. I wish it were Kevin (Harvick) winning the championship, but I’m glad we kept it in the Ford family. That was a decent way to end the season tonight for us. We didn’t qualify like we wanted Friday, but we had a good car tonight. We’ve had a good year. My guys have worked hard and had a lot of fun and a lot of success. We’re ready for a break, but it won’t be long, and we’ll be ready to go to Daytona and start the new season.”

Aric Almirola — Finished 9th: “It was a great year for us, our first year working together. That was quite an accomplishment for us to battle the way we battled and to come out of here with a top five in points, I’m just really proud of everybody on this Smithfield team. Ford had an amazing year. We won 19 races, so just an incredible year and I’m really excited about getting ready for 2019.”

Austin Dillon — Finished 11th: “Man, I really wanted a top-10 finish today to finish out the 2018 Monster Energy NASCAR Cup Series season and we came so close. Our Dow UCON Camaro ZL1 had handling issues for most of the race, but I had confidence in crew chief Justin Alexander and the Dow Racing team that they would be able to work on our Camaro ZL1 during pit stops. They’ve been great at that all season long. We knew half the battle was gaining track position and we worked hard to do that both on the track and on pit road. By the final stage, the handling improved a lot. I was digging at the end but came up just short of a 10th-place finish. That was fun. I want to thank everyone at RCR and ECR and all of our partners for a great 2018 season. We were able to accomplish a lot together and I’m looking forward to next year.”

Kyle Larson — Finished 13th: “I didn’t push it too early because I ran up there every lap, but I don’t know… I guess lost focus or whatever and hit the wall. I’m pretty mad at myself about that because I felt like we had a really good shot to win there and I just gave it away.”

Jimmie Johnson — Finished 14th: “It’s tough. When you think of the relationship with Lowe’s, I hate to see that come to an end. Seventeen, 18 years really when you look at my first three races that I ran for them, everything we accomplished together, their belief in me and the company’s support of me and this team over the years. So that is one piece and then the other piece obviously with Chad (Knaus), you know it’s time for us to move on and have a new project and have new people to work with. But he is my brother, there is just no way around it. So, not an easy situation it sure has not been easy, especially the second half of the year. We knew this was coming prior to the release or the announcement, I should say, but the season is behind us now and I look forward to a good off season and get geared up for 2019.”

Ryan Newman — Finished 15th: “Our E-Z-GO Camaro ZL1 was consistent all weekend. We turned in a great qualifying effort, made it to the final round and started eighth. No matter what changes we threw at it tonight, our Camaro ZL1 was tight through the middle of the corner and crazy loose off. I want to thank Richard Childress for giving me this opportunity to drive for him these last five seasons. To my crew chief Luke (Lambert), my crew, my teammate Austin (Dillon), and all the RCR team members, I want to say thank you. It was an honor to work with so many incredible people and partners over the years. We did great things together and it sure was fun to run for championships and give Luke his first ever Cup win.”

Ty Dillon — Finished 22nd: “I appreciate all of the hard work that this Germain Racing team put in all year long to get our GEICO Camaro ZL1 to the track every week. Our road crew leaves their families behind each weekend, and all of our guys put in countless hours at the shop. We didn’t have the results this year that we wanted, but we had a lot of great racing moments and this team never gave up. That hard work mentality isn’t going to end just because the season is over. They will all be back in the shop tomorrow morning to start building our cars for the 2019 season. We’re in this together, and there’s nobody else that I wanted battling with me tonight in Homestead and come February for the Daytona 500.”

William Byron — Finished 24th: “It was a good effort today, but things didn’t go our way. Overall, we’ve had a lot of ups and downs this season, but it’s been a good learning experience. We’ll get back after it in 2019.”

 

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.

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.
