Indycar News In 5 Minutes - Indy 500 Qualify + Crash Questions - Ep. 29
About this episode
After Indy 500 practice crashes, the hosts explain how IndyCar handles recovery—spare cars aren’t allowed, and the tub (the car’s main structural component) is what teams must address. They also cover how starting positions work when substitute drivers are involved and how technical violations during qualifying can send a driver to the back. The discussion then moves to qualifying outcomes, including Jack Harvey’s penalty, and why Carb Day practice matters for race tuning—especially with heavy rain in the forecast.
The conversation covers the impact of car wrecks on Indy 500 qualifying, the analysis of qualifying results, and the upcoming practice and race day preparation. It provides insights into the challenges faced by teams, the top and bottom 10 qualifiers, and the significance of the upcoming practice day.
Takeaways
- Spare car rules and rebuilding wrecked cars pose challenges for Indy 500 teams.

spare car
"They both wrecked their cars in practice today. So what happens next? ⁓ The first thing I want to talk about is I hear people talking about them putting together their spare car or jumping in the spare car. But spare cars are not allowed in IndyCar."
Even if a team has extra stuff, IndyCar doesn’t let them just jump into a whole backup car after a wreck. They have to use parts they can reuse from the damaged car.
In IndyCar, teams can’t simply swap to a full “spare car” after a crash. Instead, they’re limited to using spare parts, and they must decide what can be salvaged from the damaged car.
tub
"And most importantly, the tub, which is the main structural component of the car. ⁓ If they can reuse that, then they will just take broken parts off the tub and put new parts back on. If the tub is tubbed, what they call tubbed, meaning ruined…"
The “tub” is the main hard structural part of the IndyCar that everything else mounts to. If it’s badly damaged, the team has to move usable parts onto a replacement tub.
The “tub” is the main structural chassis section in an IndyCar—basically the core safety and mounting structure. If the tub is “tubbed” (ruined), the team can’t just bolt parts back on; they must transfer components onto a new tub.
starting position after a crash at the Indy 500
"So, okay, second question is, do they start at the back since they crashed their cars, which in some races they would, but no, not at the Indy 500. At the Indy 500, there's so much practice after qualifying… that if you do crash your car, you still maintain your starting position."
At the Indy 500, qualifying determines where you start. If you crash after qualifying, you don’t necessarily have to start at the back because there’s still time to get the car ready.
At the Indy 500, the starting grid is set by qualifying, and there’s enough practice time afterward that a crash doesn’t automatically force a driver to restart from the back. The key point is that the team can often repair and still keep the qualified starting position.
rookie orientation
"Hunter McElroy is the official reserve driver for ECR, but he's never been in the 500, so he would have to do one more step, which is a rookie orientation."
Before a driver can race, they have to go through IndyCar’s clearance steps. The host calls one of those steps “rookie orientation,” which is basically getting up to speed and getting approved.
IndyCar has a process to get drivers cleared to participate, especially for drivers who haven’t been in the Indy 500 recently. The host describes “rookie orientation” as the step needed to prove the driver can get up to speed and be safely integrated.
substitute driver start at the back
"So would a substitute driver, the fourth question is what a substitute driver start upfront where Alexander Rossi qualified in second. And the answer is that no substitute drivers go to the back. car number stays in its position, but drivers end up in the back."
If someone else has to drive instead of the original qualifier, that substitute driver usually has to start at the back. The car’s qualified number doesn’t change, but the driver does.
If a substitute driver replaces the qualified driver for the Indy 500, the substitute typically starts from the back of the field. The qualified car number stays where it qualified, but the driver itself is penalized to the rear.
car number stays in its position
"And the answer is that no substitute drivers go to the back. car number stays in its position, but drivers end up in the back."
Sometimes the car’s number keeps its qualifying spot, but the person driving it doesn’t. That’s why a substitute driver can be sent to the back even if the number was qualified higher.
Indy 500 starting rules can separate the qualified “car number” from the driver’s starting spot when substitutions happen. That’s why the host says the number stays put, but the substitute driver ends up at the back.
violation
"The only thing is they found a violation in his car. So he's going to the back and Scott Dixon will be in tenth."
A “violation” means the car didn’t meet the rules during inspection. When that happens, the team can get a penalty—like starting further back.
A “violation” here refers to a rules infraction found during scrutineering/inspection of the car. In IndyCar, certain violations can trigger penalties like moving the car/drivers to the back of the grid.
Juncos
"So I don't know if they didn't assemble it right or something's going over on with the car at Juncos, but I don't think anyone in the field could have driven that car."
Juncos is the IndyCar racing team. If the host suspects something is wrong “at Juncos,” they mean the problem could be related to how the team assembled or set up the car.
Juncos refers to Juncos Hollinger Racing, an IndyCar team. When the host says something may be “going on with the car at Juncos,” they’re pointing to team-side setup, assembly, or troubleshooting.
one engine
"Connor and Jack are on the same team. Jack's car's been slower all month. You know, they only get one engine when you're doing just the 500. Maybe you got a good one, maybe Connor got a good one and Jack got a bad one, who knows?"
The Indy 500 limits how many engines a team can use. If you only get one engine for the race, then the car’s performance can depend a lot on how good that one engine is.
The Indy 500 uses an engine allocation concept where teams have limited engine usage for the event. The host’s point is that if only one engine is available for the 500, teams can’t easily swap to a better unit—so performance differences may come from which engine they got.
Carb Day
"So that's qualifying. Let's talk about what's next. Well, practice didn't go so well today. It got cut off because of the crash. And the next practice is the last practice called Carb Day. [618.7s] It's on Friday. ⁓ It's called Carb Day, by the way, because back in the day, was when you set your carburetors, because the weather was most likely going to be the same between Friday and Sunday."
Carb Day is the last practice before the Indy 500. It got its name from the old days when teams adjusted carburetors on Friday so the car would be set up for the race.
Carb Day is the final practice session before the Indianapolis 500, traditionally tied to tuning carburetors. The idea was that teams could adjust the engine’s air-fuel mixture on Friday, when weather was expected to be similar to race day.
carburetors
"It's on Friday. ⁓ It's called Carb Day, by the way, because back in the day, was when you set your carburetors, because the weather was most likely going to be the same between Friday and Sunday. So everybody set their carburetors, their carbs, on Friday, hoping the weather would be similar."
Carburetors are parts that help mix fuel with air so the engine can burn it. Teams used to tweak them on Carb Day to get the car ready for the race.
Carburetors are devices that mix air and fuel before it enters the engine. In older Indy 500 setups, teams adjusted carburetors on Carb Day to match expected conditions and optimize the air-fuel mixture for race performance.
fuel injection
"There was a lot of adjusting of carburetors back in the day. They didn't have fuel injection and computers. So. Carb day is the best chance to tune the car for the race, except the current weather report shows really heavy rain on Friday."
Fuel injection is a modern way of getting fuel into the engine using controlled valves and sensors. It reduces the need for the kind of manual tuning that carburetors required.
Fuel injection is an engine system that delivers fuel into the intake using electronically controlled injectors rather than a carburetor. The host contrasts today’s systems with the older carburetor era, where teams did more manual adjustment based on weather.
race pace
"No carb day would be interesting because the teams have not had a ton of time to work on race pace, but we'll see. Some of the teams have, of course. If there is no carb day and I were you and trying to like win some money on the betting sites, I would go back and look at last like Tuesday and Wednesday's practice times."
Race pace is how quickly a car can run consistently over longer stints during the race, not just in short qualifying bursts. Practice sessions are used to dial in race pace, and if Carb Day is disrupted, teams may have less time to find their optimal long-run setup.
dirt
"and see how which team was doing well, which team was in the dirt. So that might give you some help because that's usually when they were working on race pace. ⁓ So that's good for the week."
When someone says a team was “in the dirt,” they usually mean they were not running very fast in practice. The host is saying those slower practice times might still reveal who’s actually preparing well for the race.
In racing talk, being “in the dirt” usually means a team was running slower than expected in practice. The host suggests that those practice-time trends can hint at which teams were working on race pace and performance even if they weren’t at the very top of the charts.
