Cup rookie Austin Cindric wins Daytona 500 on Roger Penske’s 85th birthday

2 Comments

Austin Cindric opened his rookie season in the NASCAR Cup Series as the winner of the Daytona 500.

The Team Penske driver captured the 64th running of the Great American Race, outdueling teammate Ryan Blaney and Brad Keselowksi, who led a race-high 67 laps at Daytona International Speedway in his RFK Racing debut after 11 seasons driving the No. 2 Ford Mustang that Cindric won with Sunday.

Bubba Wallace finished second by 0.036 seconds, followed by Chase Briscoe, Blaney (who was involved in a multicar wreck coming to the checkered flag) and Aric Almirola.

Cindric’s victory came on the 85th birthday of Roger Penske, who won the Daytona 500 for the third time as a team owner.

RESULTS: Where everyone finished in the Daytona 500

WHAT DRIVERS SAID: Notable quotes about the race

“What makes it all better is a packed house at the Daytona 500,” Cindric told Fox Sports reporter Jamie Little. “I’ve got so many people to thank. First of foremost, Roger Penske. Happy birthday! Oh my gosh. I appreciate Ryan being a great teammate, I know he wants to win this one.”

Cindric took the lead on a Lap 195 restart from Ricky Stenhouse Jr., and he survived a two-lap overtime shootout by taking the outside lane on the green flag. With Keselowski lined up behind him, Cindric got pushed to the front and tucked in ahead of Blaney, who was being pushed by Wallace on the inside.

The 2020 Xfinity Series champion expertly managed the lead from there, barely nipping Wallace by about 6 feet after throwing a final block that squeezed Blaney into the wall off Turn 4.

Cindric, 23, became the second-youngest Daytona 500 winner and the ninth driver to score his first Cup victory in NASCAR’s biggest race — and the second consecutive after 2021 winner Michael McDowell. The others are Tiny Lund (1963), Mario Andretti (1967), Pete Hamilton (1970), Derrike Cope (1990), Sterling Marlin (1994), Michael Waltrip (2001) and Trevor Bayne (who became the youngest winner at 20 in 2011).

It was the eighth Cup start for Cindric, who nearly won consecutive Xfinity Series championships before a last-lap bump by Daniel Hemric last November at Phoenix Raceway.

“Damn, I am so excited, this makes up for losing the championship in the last race I did,” said Cindric, who is the son of longtime Team Penske president Tim Cindric and began racing in NASCAR full time only in 2018 after once seemingly headed toward a sports car career (he was the lone Cup driver in this year’s Rolex 24). “I’m surrounded by great people. I know there’s going to be highs and lows being a rookie in a field of drivers this strong.

“I’m just grateful for the opportunity. Excited for the mountain we’ve got ahead of us on the 2 team, but we’re in the playoffs. That’s one good box checked. What an awesome group of fans, an awesome race car. Just really thankful.”

After a rocky, crash-filled start in NASCAR four years ago drew potshots from some drivers, Cindric’s victory Sunday drew plaudits from many NASCAR stars and peers on social media.

Penske said CIndric was “at the top of his game. I think his record speaks for itself. He really had almost two Xfinity (titles) and then to come here and have this type of victory was amazing.

“I think he’s a star coming up. I think he’s a great team player. From the perspective of our sponsors, I think he’ll represent us as a team the way we need to be so we can continue to fund his car. Look, that’s part of it. You follow me? You’ve got to be a driver, you’ve got to understand the car technically, you’ve got to be a team player, and you also have to work with your sponsors. And I think all of those buttons he touches very well.”

Wallace matched his career-best Daytona 500 finish with his second runner-up finish in the season opener on the 2.5-mile superspeedway.

“First of all, that’s pretty damn cool to win the 500, so congrats to Austin,” Wallace told Fox Sports’ Regan Smith. “What could have been, right? Man, need to talk about some happy stuff here. Just dejected, but the thing that keeps me up is just the hard work that we put into our speedway stuff and the hard work from everybody at 23IX (Racing), proud of them, can’t thank them enough.

“I knew this was a big move last year for me to go out and be competitive, and we’re showing that. It’s always the first race of the season and you’re getting through everything, but when you come out of the gates like that, it’s empowering, it’s encouraging. .. We’ll come home second. I’m going to be pissed off about this one for a while. I was happy on the first second place we got (in 2018). This one sucks when you’re that close, but all-in-all, happy for our team, happy for our partners, and on to California.”

There were two multicar wrecks in the final 10 laps that sent the race into overtime and significantly whittled the field of contenders.

Stenhouse, who led 16 laps, crashed with five laps remaining after losing the lead on a restart and then losing control after a bump from Keselowski.

The race had been red-flagged with 10 laps remaining for a multicar crash that took out contenders Chris Buescher, Kevin Harvick and Kyle Larson.

Martin Truex Jr. swept the stage victories, but his bid to win his first Daytona 500 in his 18th start ended with 48 laps remaining. Truex suffered right-front damage to his No. 19 Toyota after being collected in a multicar crash that started with Tyler Reddick spinning off Turn 4 and also collecting Jacques Villeneuve and Kurt Busch.

An eight-car crash with two laps remaining in Stage 1 eliminated several contenders after Brad Keselowski tried to push Harrison Burton toward the lead off Turn 2. Burton lost control after taking a shot to the right rear, and his No. 21 Ford slid down the banking and then went airborne after contact while turning sideways. After hitting on its roof, the car landed back on its wheels, but Burton was out of the race.

“We had a real fast Ford Mustang and ended up on our lid,” said the rookie, who led three laps and became the second driver in two days to escape injury during an airborne crash at Daytona. “Just a frustrating weekend. We worked really hard all week to lead up to that. It’s hard to see. It’s hard for me to tell what happened.

“Just felt like I got a push in a bad spot in the bumper and got shot to the inside before I could save it. Frustrating deal, wanted to get stage points, tried to be smart about it and just got turned around there.”

The wreck also took out Ross Chastain, Christopher Bell, William Byron and Denny Hamlin, who suffered his first DNF in 17 starts at the Daytona 500.

“(Burton) was getting out of control, and (Keselowski) was insistent on pushing him at all costs, and it eventually turned him around,” Hamlin said. “Tough considering it was only for the stage. Too aggressive pushing right there when they weren’t lined up and in control.”

Keselowski addressed the accidents with Burton and Stenhouse after the race.

“I was just pushing (Burton), and it just turned sideways and spun immediately out,” Keselowski said. “I don’t know what happened there. It was a shame to see it.  I hate it for him.  I was trying to help him win the stage and certainly didn’t want to see him spin out.

“The same thing (in the Stenhouse wreck). I was just pushing. We weren’t even all the way up to speed, so I feel like it was a crazy time to be pushing, but obviously the results say different. Whenever somebody spins out obviously there’s somebody overaggressive, but in the moment I didn’t (feel too aggressive).”

STAGE 1 WINNER: Martin Truex Jr.STAGE 2 WINNER: Martin Truex Jr.

WHO HAD A GOOD RACE: Aric Almirola finished fifth in the first start of his final season in Cup. … With a seventh, Michael McDowell has four top 10s in his past five Daytona 500s. … David Ragan finished eighth in his first Cup start since the 2021 Daytona 500.

WHO HAD A BAD RACE: Alex Bowman also finished multiple laps down after getting caught in the Burton crash. … It was an inauspicious debut for the single-lugnut wheel as multiple drivers had problems with the new Next Gen feature. Kaz Grala (in the first race for Floyd Mayweather’s new team) caused the first yellow on Lap 42 when his right rear tire came loose. Another yellow flew 11 laps later for Justin Haley, who lost the right front while making the first start in Kaulig Racing’s new No. 31. Goodyear officials said both wheels were left loose. … Greg Biffle’s first start in the Cup Series since 2016 went south quickly, completing only 26 laps before heading behind the wall with NY Racing.

New NASCAR Cup season features several changes

0 Comments

While NASCAR looks back in celebrating its 75th season, there’s plenty new for the sport heading into the 2023 campaign.

Driver moves and schedule changes and are among some of the big changes this year. Here’s a look at some of the changes this season in Cup:

Drivers

— Two-time Cup champion Kyle Busch has a different look, as he moves from Joe Gibbs Racing to Richard Childress Racing, taking the ride formerly occupied by Tyler Reddick. 

— Tyler Reddick goes from Richard Childress Racing to 23XI Racing, taking the ride formerly occupied by Kurt Busch, who was injured in a crash last summer and has not returned to competition.

Ryan Preece goes from being a test driver and backup at Stewart-Haas Racing to taking over the No. 41 car formerly run by Cole Custer, who moves to the Xfinity Series. 

— Seven-time Cup champion Jimmie Johnson returns to Cup after running the past two seasons in the IndyCar Series. He’s now a part owner of Legacy Motor Club and will run select races for the Cup team. Johnson will seek to make the Daytona 500, driving the No. 84 car.

Ty Gibbs goes from Xfinity Series champion to Cup rookie for Joe Gibbs Racing.

Noah Gragson goes from Xfinity Series title contender to Cup rookie for Legacy Motor Club (and teammate to Jimmie Johnson).

Crew chiefs

— Keith Rodden, who last was a full-time Cup crew chief in 2017 with Kasey Kahne, is back in that role for Austin Dillon at Richard Childress Racing, as Dillon seeks to make back-to-back playoff appearances. Rodden comes to RCR after working with the Motorsports Competition NASCAR strategy group at General Motors.

— Chad Johnston, who has been a crew chief for Tony Stewart, Martin Truex Jr., Kyle Larson and Matt Kenseth, will serve as crew chief for Ryan Preece at Stewart-Haas Racing.

— Blake Harris goes from being Michael McDowell’s crew chief at Front Row Motorsports to joining Hendrick Motorsports to be Alex Bowman’s crew chief. 

— Mike Kelley, who served as Ricky Stenhouse Jr.’s crew chief when Stenhouse won Xfinity titles in 2011 and ’12, returns to the crew chief role with Stenhouse this season at JTG Daugherty Racing. 

Races

— What’s old is new. The All-Star Race moves to North Wilkesboro Speedway in May, marking the first Cup event at that historic track since 1996.

— July 2 marks debut of the street course race in Chicago, marking NASCAR’s first street race for its premier series.

— The spring Atlanta race and playoff Texas race have both been reduced from 500 miles to 400 miles.

Rules

Ross Chastain’s video-game move on the last lap at Martinsville will no longer be allowed, NASCAR announced this week. 

— Stage breaks are gone at the road course events for Cup races. Stage points will be awarded but there will be no caution for the end of the stage.  

— If a wheel comes off a car while on track, it is only a two-race suspension (last year it was four races) for two crew members. The crew chief is no longer suspended for the violation. 

— Cup cars have a new rear section that is intended to absorb more energy in a crash to prevent driver injuries after Kurt Busch and Alex Bowman each missed races last year because of concussion-related symptoms.

— Elton Sawyer is the new vice president of competition for NASCAR. Think of the former driver as the new sheriff in town for the sport.

Achievements 

— With a win this season, Kyle Busch will have at least one Cup victory in 19 consecutive seasons and become the all-time series leader in that category, breaking a tie with Richard Petty.

Denny Hamlin needs two wins to reach 50 career Cup victories. That would tie him with Hall of Famers Ned Jarrett and Junior Johnson for 13th on the all-time list. 

Kevin Harvick, running his final Cup season, is 10 starts away from 800 career series starts. That would make him only the 10th driver in Cup history to reach that mark.

Friday 5: Clash at Coliseum provides a reset for RFK Racing

0 Comments

Mired in traffic was not where Chris Buescher expected to be. Sure, he knew that racing 22 cars on a quarter-mile track inside a stadium that has hosted the Super Bowl, Olympics and World Series would put him in tight confines, but when the green flag waved for last year’s Busch Light Clash at the Los Angeles Memorial Coliseum, Buescher was in traffic on the freeway.

He was headed to the airport — along with the rest of RFK Racing. 

Both Buescher and team owner Brad Keselowski failed to make last year’s feature, sending them home earlier than expected.

“A punch to the gut,” Buescher told NBC Sports.

NASCAR’s return to the Coliseum for Sunday’s Clash is not a redemption tour for RFK Racing, said Jeremy Thompson, the team’s vice president of race operations. He calls it a reset.

That’s what last year was thought to be with Keselowski leaving Team Penske to become an owner/driver of an organization that had gone more than four years without a points victory before 2022. The Clash was a chance for RFK Racing to show its new direction.

Instead, RFK Racing and Spire Motorsports were the only multi-car teams not to have a car in the feature.

“Yes, it was not a points race, but it just looked bad,” Buescher said. “And it was bad. It hurt our feelings more than anybody else’s, I promise.”

Through that disappointment, lessons were learned.

“We didn’t have a lack of hunger that was holding us back,” Keselowski said of last year’s Clash. “We had a lack of understanding our vehicle dynamics. Understanding was just not good enough on a lot of levels.

“We continue to invest in resources and people to continue to push that forward to where we can go to events like that and feel that we’re a threat to win and we’re not just trying to make the race.

“I don’t think I understood that when I came in, where we were at as a company on the vehicle dynamics side.”

It was clear immediately that Buescher and Keselowski were in trouble. Buescher was 21st on the speed chart in practice; Keselowski was 33rd of 36 cars. 

“The car bounced so bad that I thought we were going to rip the transmission right out,” Buescher said of last year’s Clash weekend. “We spent all of practice trying to make the car just drive in a circle vs. trying to make it faster. We missed … before we ever left (the shop).”

Said Thompson about last year’s Clash: “I felt like our effort going into that was exceptionally high. We left no stone unturned. We just turned over some of the wrong stones.”

Two weeks later, both Keselowski and Buescher won their qualifying races at Daytona, but there was much work to do to overcome flaws with other parts of their program.

“We’re pushing really hard on vision and values of what it takes to be a high performer at this level, whether that is getting all the details right in the shop or on the road,” Keselowski said.

RFK Racing learned from its struggles early in the season, particularly with its short track program. Buescher, who had never placed better than 16th at Phoenix at the time, finished 10th there last March, a little more than a month after the Clash. He called his top 10 that day “a small win.”

Progress continued but it was not quick. Buescher placed third at Richmond last August before winning the Bristol night race in the playoffs. Keselowski was seventh at New Hampshire last July and won the first stage at the Bristol night race in September before a flat tire ruined his chances.

Keselowski acknowledges that turning RFK Racing into a team that can contend weekly for wins will take some time, but he sees progress.

“We’re not everywhere we need to be, but we definitely have a plan to get there,” he said. “Navigating that plan is challenging, but we’re on a path.”

2. Why not more horsepower?

NASCAR will take what it learned in last week’s Phoenix test to the wind tunnel on Feb. 13. If the wind tunnel test of short track enhancements goes well, changes could be implemented before the April 2 race at Richmond.

The changes being tested in the wind tunnel are a smaller spoiler (2 inches) and some adjustments to the underbody of the car. 

Still, one suggestion drivers often make is to give them more horsepower.

“I think there’s a misconception that we could take the existing engines and just throw 200 horsepower in it,” said John Probst, NASCAR’s chief racing development officer, in response to a question from NBC Sports. 

“We do have multiple-race engines today that we have to keep in mind. (More horsepower) is something that we are actively discussing, but, obviously, we don’t do that in a vacuum. We do that with the engine builders.

“But anybody that has been around, we’ve raced high horsepower and low downforce before and ended up at some point in time deciding to go away from that to get more entertaining racing. … I think we’re open to entertaining any horsepower gains that we can get with our current (engine) architecture, but anything beyond that is actually not something that can happen quickly.”

Probst later said that keeping the engines in the current horsepower range could prove helpful for any manufacturer looking to join the sport.

“One of the reasons we landed on the horsepower range we’re in now is to try to land in areas that have existing racing engines designed for them, similar to our current (manufacturers),” Probst said. “We’re not hiding from the fact that we would like to encourage some new (manufacturers) to come in. That is part of the equation for that whole thing. I’m not saying it’s the driving reason, but it is a consideration.”

3. Crossing the line

The quarter-mile oval in the Los Angeles Memorial Coliseum will provide plenty of chances to hit bumpers, doors and other parts of the car Sunday.

But there’s a line between short track racing and racing without respect. 

For Ryan Preece, who is running his first race in the No. 41 for Stewart-Haas Racing this weekend, there is a clear divide.

“There’s certainly a way to go about it in quarter-mile racing where you can pass somebody without hitting them,” said Preece, a veteran of racing modifieds in bullrings. 

So how does he tell what’s crossing the line on a short track?

“If somebody drives into me getting into the center of the corner, they’re in control of their race car at that point,” Preece said. “So that or door slamming somebody, not even trying to make the corner, are two good examples (of not racing with respect).”

Preece relies on a lesson he learned racing modifieds with how to race in close quarters.

“I’ll never forget this, I was at Thompson (Speedway) and I used (seven-time modified champion) Mike Stefanik up pretty well into Turn 2 with probably six or seven laps to go, trying to chase down the leader. It didn’t happen. 

“I said, ‘Oh, hey man, I’m sorry. I had to do what I had to do for my team.’ He looked at me and said ‘Well, what about my team? What about the guys I race with?’ 

“I think that day really helped me understand that side of things. You want to race with as much respect as you possibly can. There’s a way to do it, a way to race somebody hard but not overstep the line.”

4. On the same page

Ty Dillon moves to Spire Motorsports this season as a teammate to Corey LaJoie.

Dillon will drive the No. 77 car, which has never finished in the top 30 in car owner points since its debut in 2019. The best the car placed was 31st in owner points in 2021.

Dillon says he has confidence in building the program based on Spire Motorsports’ approach.

“We aren’t unrealistic about where we are,” Dillon told NBC Sports.

But he also said that management has workable goals.

“We said, ‘Hey, here’s where we stand in the spectrum of the race teams,’ ” Dillon said. “Here’s our goals. Here’s what we believe we can accomplish. The structure of what everybody knows and how we’re all pulling in the same direction is a real confidence (boost).

“We know we’re not going to be the team that competes every single weekend for wins, but we’re going to be the best at who we are. Over time, people are going to say, ‘Damn, Spire has taken a step.’ … We’re long-term focused and everybody’s on the same page as that.

“I’ve been a part of a team that said, ‘Hey, we’re wanting to build something.’ Well, you get 10 races in and they haven’t won a race and they’re throwing everybody out the door.”

Dillon said the “realistic, genuine expectation” at Spire Motorsports makes this situation feel different for him.

“The hope and optimism is knowing that we’re all on the same page,” he said.

5. Rule book changes 

NASCAR announced a series of rule changes this week and stated that it would outlaw the video game move Ross Chastain made on the final lap of last year’s Martinsville race. 

NASCAR also made a number of changes to the rule book this week.

Among those:

— Intentionally damaging another car on pit road could lead a Cup driver to be penalized 25-50 points and/or 25-50 owner points and/or $50,000 – $100,000 fine. Last year, intentionally damaging another car on pit road could lead only to a fine of $25,000 – $50,000.

— Member to member confrontations with physical violence and other violent manifestations could result in a fine and/or indefinite suspension or membership revocation. Last year, such an infraction was listed as incurring a penalty of 25-50 driver and/or team owner points and/or a fine of $50,000 – $100,000. Violations also could result in a race suspension(s), indefinite suspension or termination.

— In the past, if a car could not go when it was time to make a qualifying attempt, it was put on a five-minute clock to do so. That’s changed this year. Now, the clock will be no more than one minute unless it is a safety issue. 

Also, NASCAR listed the length of each Cup race. The inaugural Chicago Street Course Race is scheduled for 100 laps.

Harrison Burton looks for progress in second year in Cup

0 Comments

Harrison Burton made the first start of his NASCAR Cup Series partnership with the Wood Brothers in the bright lights of Los Angeles.

Burton and the Woods teamed last season as Burton jumped into full-time Cup racing after two full seasons (and four wins) in the Xfinity Series. Their first race was the Clash at the Coliseum, and it was a good start — Burton qualified for the feature and finished 12th on the lead lap.

Then things headed downhill. Crashes at Daytona and Auto Club Speedway left Burton with finishes of 39th and 33rd, respectively. After the first five races of the year, he had four finishes of 25th or worse.

Now, Season Two, and there are higher expectations. Much higher.

“The start of last year was really, really rough,” Burton told NBC Sports. “It kind of put us in a hole. We got into the wreck in the 500 and crashed at Fontana. Things kind of stack up on you, and all of a sudden you’re buried in points and it’s hard to make it back up.

“But, at the end of the year, three of the last four weekends were big for us (three consecutive top-20 finishes). We need to build off that and try to get out of the West Coast swing and have a clean group of those races. That’s really important. We need to get our average finish up in the first four to five races and not put ourselves in a hole we can’t get out of, and then go from there.”

The Wood Brothers team typically brings strong cars to the Daytona 500, the season’s first point race. Trevor Bayne scored the team’s latest win in stock car racing’s biggest event in 2011.

“We ran well in the 500 last year until I was upside down,” Burton said. “We had a fast car and qualified well and finished third in our duel. Then in the second Daytona race we put ourselves in good position late, so we were in contention in both Daytona races. The speed was there, and the cars drove well.”

The team’s primary goal is to make the playoffs, Burton said. “And we want to be a contender,” he said. “Cup races are so hard. First, you have to contend. Having a good average finish is really important. If you average around 17th or 18th all year, you can kind of point your way into the playoffs, and doing that is on our minds for sure.”

Burton looks for a strong start in Sunday’s Clash, which will present teams with a mix of the old and the new. Drivers got the experience of racing inside the Los Angeles Memorial Coliseum last year, and notes from that race will be useful, but the racing surface will be all new again.

“Every repave has a different tendency,” Burton said. “We’ll see how close it is to last time and how different. Obviously, there is experience on that track, but still it’s a completely new surface, so it’s going to be a mixture of old and new. There’s some knowledge we can build off of, but we kind of have to go into the weekend with that knowledge as tentative because we don’t know if the track is going to be different.”

Burton heads for Los Angeles with a win already under his belt this year. He and teammate Zane Smith, last year’s NASCAR Craftsman Truck Series champion, won last Friday’s International Motor Sports Association’s Michelin Pilot Challenge Series race on the Daytona International Speedway road course.

Burton drove the finishing laps in the four-hour race. He was third with about 50 minutes to go but moved in front with 22 minutes left when leader Elliott Skeer parked. Burton outran second-place Spencer Pumpelly by .688 of a second for the win.

“I thought we could run well,” Burton said. “After the test we did, we were really fast, so I was pretty excited. But apparently there is a lot of sandbagging that goes on there, so I wasn’t sure where we were. We had to have some things go right for us, and they did.”

 

 

 

 

Dr. Diandra: Muffling racecars won’t change fan experience

1 Comment

Last week, NASCAR tested the muffler that will be used for Sunday’s Clash at the Coliseum.

“Heresy,” some fans cried. They argued that it is against the laws of man and nature to muffle racecars. That noise is an integral part of the fan experience. That you’re not supposed to be able to have conversations during races.

Relax.

The cars will be plenty loud.

Loud is fast

Engines produce power by combusting fuel and air in their cylinders. Each combustion produces high-pressure gases that push the piston up. The same gases make a loud popping sound when they escape the cylinder and finally the exhaust.

At 8,000 rpm, an eight-cylinder engine performs about 520 combustions every second. The faster an engine runs, the more combustions per second and the higher the frequency of the tailpipe noise.

That’s why NASCAR engines sound like grizzly bears and F1 engines, which run at higher speeds, sound more like angry mosquitoes.

Maximum horsepower requires getting the spent gases out of the cylinder as quickly as possible so the next combustion reaction can start. And that’s the problem with mufflers, from a racing perspective.

Mufflers on street cars bounce sound waves from the engine around a metal can. The waves interfere with each other, which decreases the overall volume coming from the exhaust.

Mufflers can also mitigate noise by directing the exhaust through a sound-absorbing material. Borla, the sole-source supplier for this weekend’s muffler, makes commercial racing mufflers that feature a robust sound-absorbing material superior to the commonly used fiberglass.

Both methods slow the exhaust gases — the first more than the second. The ideal racing muffler diminishes sound with minimal horsepower reduction.

Decibels

Sound-level measurements come in decibels (dB), a unit named after Alexander Graham, not Christopher — and apparently by someone who wasn’t the best speller.

But decibels don’t tell the whole story. Sound intensity decreases with distance, so you need to specify how far away the sound source was.

The easiest way to explain the decibel scale is to relate it to real-world noises, as I’ve done below.

A bar chart showing representative sound levels expressed in decibels.

  • Zero dB is the threshold of human hearing.
  • A whisper you can just barely make out is about 20 dB.
  • Most everyday noises are in the 60 dB to 100 dB range but are sometimes louder.
  • Exposure to 130 dBs can be painful.
  • A 150-dB sound can cause permanent hearing damage in a very short time.

Ringing in your ears the day after a rock concert was a badge of honor in high school. Older me wishes I had been a little smarter.

Hair cells — not to be confused with ear hair — facilitate hearing. Sound bends these hair-shaped cells, and the cells convert sound into electrical signals that the brain interprets. Loud sounds can bend these cells so much that they break.

Unlike animals such as sharks, zebrafish — and even the lowly chicken — humans cannot grow new hair cells. Once your hearing is damaged, you can’t get it back.

How loud are racecars?

A noise mitigation study for the proposed Nashville Fairgrounds track measured a single Next Gen car at COTA generating 112 dB on a straightaway at 100 feet.

A 2008 study measured the sound level inside a Gen-6 car to be an average of 114 dB. The study also compared sound in the stands, the infield and the pits.

Let’s add those numbers to our graph.

A bar chart showing representative sound levels expressed in decibels, including sound measurements from the Gen-6 and Next Gen cars

  • The Next Gen car at 100 feet is about the same loudness as a person screaming at top volume 1 inch from your ear.
  • The Next Gen car at 100 feet is just a bit quieter than sitting inside the Gen-6 car.
  • Bristol reached peak sound levels loud enough to cause permanent hearing damage.

The graph data suggests that inside the Next Gen car should be around 10 times louder than inside the Gen-6. Some drivers made new earmolds to cope with the additional noise in the cockpit.

Because of the way sound works, the numbers don’t add like you’d expect them to. A Next Gen car might be 112 dB, but two Next Gen cars are more like 115 dB. A full field would be only 5-7 dB louder.

The mufflers won’t muffle much

NASCAR expects a six to 10-dB reduction in sound with mufflers. A 10-dB reduction would make the Next Gen car about as loud as the Gen-6 car was.

Another way of looking at it: Good earplugs reduce sound levels by 25 to 30 dB. Wearing earplugs just barely gets you into the range of being able to hold a conversation if you stand very close to each other and you both shout.

You won’t notice the change in sound inside the track.

You also won’t notice a change in speed this weekend, despite a drop of 30-40 horsepower. The Next Gen car takes around 14 seconds to traverse the L.A. Coliseum’s quarter-mile track. That means cars won’t be going much faster than typical expressway speeds.

If you’re headed out to the track this weekend — despite the mufflers — bring earplugs or over-the-ear headsets. This is especially important for children, as their hearing is more easily damaged.
