Ryan: A requiem for the bump and run? Delving into the short-track debate gripping NASCAR

RICHMOND, Va. – When it comes to the ongoing debate about what makes a NASCAR short-track race great, let’s concede the obvious.

The loudest voices on the subject also are those whose should matter least.

“A driver is going to like whatever he’s best at,” Brad Keselowski told a small group of reporters Friday at Richmond International Raceway. “That’s why you can’t ask an active driver, because an active driver is going to tell you if he’s good at running the top, that’s where the race needs to be. If he’s good at running the bottom and with the bump and run, that’s where the race needs to be.

“We always will give the selfish answer. I think it’s probably one of those questions that maybe current drivers shouldn’t answer out of respect to their answers being selfish. In reality, we need the answer that drives the sport and creates the most compelling action. That should be the guiding light before a driver’s preference.”

A two-time winner at Bristol Motor Speedway (but none since the 0.533-mile oval was altered in 2012 in an attempt at re-establishing the bottom lane that actually created a preferred high line), Keselowski naturally prefers the low lane and the bump-and-run maneuvers that helped drive the track’s growth to a 160,000-seat colossus.

But many of his peers had opposing views on what defines a great short track. Points leader Kyle Larson doggedly worked in the high line during practice (attempting to negate the VHT applied to force drivers to the bottom) and incessantly lobbied before and after the race that the better Bristol was high and low.

Did he feel vindicated by a race that drew a high favorable rating in one popular online poll?

“I would say more people probably agreed with me by the end of the race,” Larson said. “You still had your older race fans that enjoyed the single-file racing around the bottom, but I know all the drivers enjoy when we can move around and find different lines on the racetrack because at least from our seat — maybe it doesn’t translate to TV as well — the racing is way better that way.

“And I thought Bristol last week was awesome. … There’s no other track on our circuit that has that exciting and intensive racing. I watched the race again last night and I thought it was amazing. Hopefully they don’t try and do anything more to make us go around the bottom because Bristol is awesome.”

OK, but what about the bump and run?

Larson, a longtime dirt racer who admittedly has a different perspective on the “rubbing is racing” philosophy, makes a few good points why it can’t work the same way anymore.

“The pace of our races nowadays have to be way faster than what they were running in the early 2000’s or whenever the best racing at Bristol was,” Larson said. “And, too, our bumpers line up. So, it’s not easy to do the bump and run. People do hit somebody in front of them, and the guy in front of him barely moves. Before the bumpers lined-up, you could get into somebody, pick them up, and move them.

“So, the bump and run is kind of gone away a little bit just the way I think our style of our bodies are, as well as I think we have more grip now days than they probably had back then. … I don’t think you’re going to get all the way back to how they all like it.”

If that truly is the case, then here’s a brief requiem for the bump and run to remember exactly why it’s so beloved … through five moments at Bristol.

2008: Carl Edwards vs. Kyle Busch

2002: Jeff Gordon vs. Rusty Wallace

1999: Dale Earnhardt vs. Terry Labonte

1997: Gordon vs. Wallace

1995: Earnhardt vs. Labonte

That’s the racing that is synonymous with Bristol – a point that NBCSN analyst Jeff Burton eloquently made here. You won’t find many stirring side-by-side battles for a win hailed among the greatest races at Bristol.

And that is what should give anyone pause about proclaiming that Sunday’s race should be the only path forward.

Quick, name the most indelible moment you remember from Martinsville Speedway this season?

The “purists” will point to the battle for the lead between Keselowski and Busch.

But the realists will point to Ricky Stenhouse Jr. bumping aside Busch at the end of the race’s second stage as the highlight with the most traction in national media.

It also drew some of the loudest cheers during that race at Martinsville a few weeks ago.

Don’t forget about those voices. As Keselowski notes, they still matter most.

With the perceived success of Bristol being treated with a VHT-style compound for the second consecutive race, it’s natural to ask whether it should be tried at other tracks – such as Richmond.

When owned by the Sawyer family, RIR actually was treated from 1988-2002 with a sealer that drivers loved, but the surface has remained untouched since a 2004 repave.

With Richmond producing divergent results in recent races – some are wildly competitive, others aren’t – there are mixed feelings on whether the 0.75-mile oval needs some help.

“If you ask the drivers, this is the perfect racetrack,” said Denny Hamlin, a hometown favorite who has attended races here since childhood. “To the fans, sometimes it’s not, because (the cars) do get strung out.

“I think the reason the drivers and teams like it best is because they hit their setup, they can just dominate a race here. It’s not always the best thing for TV, but it’s a good thing for the competitors. So it’s a balance of what’s good for the competitors and what’s good for putting on a fantastic race.

“I don’t know what you can do here. We’ve had races where we were running the wall or running the line and some guy led almost every lap. I don’t know whether spreading out the cars or making them run one line here is the best thing to do.”

Said Larson: “All of us complained a few years ago when it was single file around the bottom the whole time (at Richmond) and then Goodyear brought a great tire back, and now we’re running all over the racetrack, and the drivers and fans seem to like it. I think the racing is good, really good right now, and a lot of fun, too.”

Dale Earnhardt Jr.’s busted oil cooler at Bristol was one of a few mechanical problems that seemed caused by debris on the track – which might indicate a possible downfall with VHT. Does the substance increase the “chunking” by tires and subsequently the likelihood of cars being damaged?

Regardless, it’s left Earnhardt in a precarious points position in his final Cup season. It would seem his best route to the playoffs would be via his first win in 18 months – putting extra emphasis on how next week’s race at Talladega Superspeedway. Earnhardt has six wins (most recently two years ago) on the 2.66-mile oval, which ranks him first among active drivers.

“Daytona seems to be more about the car, Talladega more about the driver and the moves, and (Earnhardt) makes some of the best moves,” Keselowski said. “So I would expect him to be one of the primary guys to beat for sure.”

Is it May yet?

Because it’s about time for the hagiography around Fernando Alonso’s foray into IndyCar to end and for the journalism to begin.

Getting a two-time world champion committed to the world’s biggest race (as Alonso described it in his own words during an NBCSN interview last Sunday that surely had to deliver a sting for some in Formula One and his team) is undoubtedly a coup. The series justifiably maximized that exposure value during the Spaniard’s visit to Barber Motorsports Park last weekend.

Alonso is signing autographs! Alonso is climbing into Marco Andretti’s car! Alonso is talking to every microphone within shouting range!

All of this was great promotion for IndyCar, which could use the injection of attention as it tries to avert the letdown from following the centennial marking of its signature event.

But can we cool it a tad until he, like, turns an actual lap?

Because the narrative needs to shift gears well before then and explore some significant storylines. For example …

–When was the last time a driver with NO (as in zero!) oval experience before the month of May attempted to run one of the world’s toughest racetracks in an entirely new race car?

Last year’s surprise winner, Alexander Rossi, had several hundred laps around Phoenix International Raceway before the former F1 driver took the Indy plunge. Rubens Barrichello didn’t have that IndyCar oval race experience before his 2014 debut at Indy, but he at least had four races on street and road courses to get acclimated to the vehicle.

Ask Tony Stewart, who repeatedly has said among their biggest apprehensions about attempting the Indy 500 would be the lack of time in an Indy car beforehand. Alonso is in a class of his own, but it certainly is worth pondering if he can overcome others’ concerns about adaptability.

–How does the current pack racing that has become prevalent the last few years at the Brickyard make it more or less difficult for Alonso?

–How will Andretti Autosport manage the balancing act of fielding a competitive car for Alonso with five other entries? (At least one reporter has attempted to pose this question and unfairly been pilloried as a result).

Regardless of the answers to these and other questions, Alonso’s Indy 500 debut will rank among the most highly anticipated in recent racing memory.

It’s fine to celebrate the significance of that … but with a healthy dose of objectivity and perspective, too.

The impending retirement of Earnhardt in the wake of Jeff Gordon and Stewart has kicked the discussions into hyperdrive about the next wave of superstars (and yes, as the employee of a NASCAR broadcast partner, I will plead guilty to being complicit in driving that conversation – a legitimate one).

While there has been justifiable focus on Larson, Chase Elliott and Ryan Blaney because of their performance this season, and Daniel Suarez has gotten much attention because he is filling Carl Edwards’ ride, rookie Erik Jones mostly has been lost in the shuffle.

And it seems he might have noticed.

Based on the speed of his No. 77 Toyota the past two days, it isn’t inconceivable that Jones outruns the trio – if not outright win – at Richmond.

Keep in mind that, as we noted on the Michigan Home Track segment NASCAR America this week, Jones, 20, was winning prestigious Late Model races as a 14-year-old.

There are some obvious candidates for the No. 88 ride, and that’s why William Byron’s noncommittal response was delivered correctly and perfectly Friday. The 19-year-old assuredly will race Cup for Hendrick in the future, but it doesn’t help to do anything but keep it boring when asked to speculate for now.

But there were some other answers from veterans that seemed a little … curious. For example, would Larson like to put to bed the rumors that he could go to Hendrick (which once courted him)?

“Oh, I’d have to talk to (team owner) Chip (Ganassi), I guess, before I came out in public about anything that serious,” he said. “So, I won’t talk about anything like that because I don’t even know if I’m allowed to, or not. I know (teammate) Jamie (McMurray) is very secret about all his stuff. But I don’t know.”

Any interest from Keselowski, who is in a contract year with Team Penske?

“Do I have to have a yes or no? It’s a Hendrick car, which by nature means it’s going to be one of the best cars available for a long period of time,” he said. “But I also would say the car that I’m in is one of the best available. The team I’m with, I have a lot of equity in, so I’m pretty darn happy where I’m at, but I’ve learned in this world to never say no.”

So is he negotiating an extension?

“There’s some stuff going on, but I’m not (going) to mention it in detail,” he said.

Hmmm.

Our take on this? Neither driver is leaving where they are. Larson’s current deal likely keeps him in the No. 42 for at least another three seasons, but Ganassi notoriously is tight-lipped about his contracts, hence his reticence.

Keselowski seems happy at Penske, but he has driven before for Rick Hendrick, who intimated he would like to bring him back in the fold someday as he was exiting to join The Captain.

Even if he is 100 percent committed to staying at Penske, having the leverage to secure the best-paying deal possible (from one of the most business-savvy owners in racing) is a good thing.

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
Click for a larger view

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.
