Sunday could be interesting.

As of Friday morning, two days before the 103rd running of the Indianapolis, the current forecast for Sunday’s race has a 75% chance of rain around the green flag at 12:45 p.m. ET, according to the hourly forecast on the Wunderground.com website.

Indianapolis Motor Speedway president Doug Boles said track officials are monitoring Sunday’s weather daily but won’t discuss any potential contingency plans until Saturday night. Regardless of whether it’s raining Sunday morning, some pre-race ceremonies likely will remain in place.

“It’s hard to speculate on what’s going to happen,” he said. “It’s likely Sunday morning will be the first time that we have any definitive statement on what we think is going to happen. Instead of giving you information that we don’t know what it’s going to be like, I’d rather wait until that Sunday when we see the conditions, and we’ll let you know.

“Obviously, if it’s raining, and then we’ll have to decide what the next steps are.”

Boles said Indiana weather traditionally is unpredictable, noting that qualifying was completed last Sunday despite predictions of a complete washout.

“Last year the prediction was it was going to rain on race day, we got up next morning, and it was perfect,” Boles said. “It just changes so rapidly around here.”

Should it rain, IndyCar officials will make every reasonable attempt to run the Indy 500 on-time, with the race scheduled to begin at 12:45 p.m. ET on NBC. The Indianapolis Motor Speedway also recently used a new sealant on the track surface which makes it quicker to dry the racing surface.

So what happens if it does rain? Some options:

Rain-shortened race

The Indy 500 could turn into the Indy 255. If more than 255 miles (102 laps) are completed in Sunday’s race, the race can be deemed official if heavy rains halt all on-track activity. If the race is called, driver’s finishing positions are based on their position in the race at the time of the caution flag for rain coming out.

The Indy 500 has been shortened by rain only seven times, most recently in 2007. The race was stopped for rain nearly three hours because of rain on Lap 113 and was declared officially over when rain once again forced the race to come to a halt at the 415-mile mark.

Partial postponement

If less than 102 laps are completed Sunday, the race will resume on the next dry day. With most Americans off-work on Monday due to Memorial Day, a partial postponement would not be the end of the world to fans at the track and watching on NBC.

The race has only been partially postponed twice in the 102 previous runnings, in 1967 and 1973.

Complete postponement

Fans shouldn’t worry too much about a complete postponement of the race, as it has only happened three times, most recently in 1997. If rain completely postpones the Indy 500, the race will be rescheduled for the next day, with start time dependent on the forecast.

The 1997 race ran 15 laps on Monday, before rains once again postponed the remainder of the race until Tuesday. The 1915 and 1986 runnings were postponed until the following Saturday.

NEOM McLaren Racing Formula E and Ian James set to race ahead of electric motorsports’ curve

As Formula E enters their ninth season and McLaren Racing is set to compete in last year’s championship winning car, Ian James is passionate about pushing electric motorsports forward at a critical stage as race technology begins surpassing that of the street cars.

Midseason, McLaren acquired the assets of the Mercedes-EQ team as they were already on their way to winning a second consecutive championship. With those assets in place and coming off a successful debut in the Extreme E series, James is set to usher in a new era in electric car racing.

Last week’s announcement that Jake Hughes will join Rene Rast behind the wheel of the NEOM McLaren Formula E team was the last piece of the puzzle.

McLaren’s electric portfolio is building with the Formula E team coming one year after they entered the Extreme E rally series in 2022 with Tanner Foust and Emma Gilmour. There were a lot of lessons to learn in that series with growing pains during the first three of five rounds. Rounds 4 and 5 were a completely different matter with the team crossing the finish line first in Chile before being assessed a time penalty.

In the final round in Uruguay, they scored an elusive podium.

“McLaren kicked off the season in Extreme E at the beginning of this year, so our first [electric] race took place Neom, actually out in Saudi,” NEOM McLaren Racing Team Principal James told NBC Sports. “At the time, we were in very early discussions about opportunities with the Formula E team. I actually went out there to meet with Zak [Brown, CEO McLaren Racing] and that was my first taste of Extreme E.

“Since the transition, I joined them in Chile in Atacama Desert, and then Uruguay last weekend. [The second-place finish was] a lovely way to round out the season. The fact that they got that podium. It was very well deserved. It’s a great team and a great series actually. It’s just so very different from anything else. The team’s done a great job in getting set up, and it’s nice now to, we’re trying to use that momentum that we’ve got from Uruguay to get us into next season when it kicks off next year, which will be great. I think we’re mid-March is looking like the first race, so a little bit of time to get things prepped for that.”

Synergies exist between the single seater and rally series. Lessons learned about battery power and sustainability in the electric SUV carry over so long as one is mindful of keeping focus on the individual needs and nuances of each series.

Especially now that electric racing technology has caught up, and is ready to surpass, the existing technology that has gone into building street cars.

When internal combustion engines gained the upper hand soon after automobiles were invented, racing paced alongside. The pressure of competition pushed the development of their commercial equivalents. The same has not necessarily been true of electric cars. Street cars were not designed to undergo the same stress as racecars – and that vulnerability showed up on the racetrack.

“Formula E has come along a long way,” James said. “I think one of the most notable developments is in the battery technology. In Gen 1, you had the drivers jumping from one car to another car midrace because the battery technology and capacity simply wasn’t where it needed to be to do the full distance. That obviously changed in Gen 2 and we saw a power increase as well to the 250 kilowatts.

“Now going to Gen 3, we have 350 kilowatts in a smaller battery. But that means that we’re relying on the regeneration of energy and for that reason, we’ve got also the opportunity to regenerate on the front axle as well as the rear axle now. So, there’s all sorts of things that are developing in the right direction.

“In terms of throttle response, actually, we’re now in a situation with electric racing and the motors that it’s instantaneous. And one of the advantages of electric over combustion engine is that the torque is instantaneous as well, so that gives you a lot more room to play with.”

No matter the power source, racing has always been about resource management. Drivers and teams select tire strategies they believe produce the fastest elapsed time and fuel conservation comes into play.

On one hand, electric racing is the same, but there is a critical difference. With the battery as both the power source and an integral part of the engine, there are multiple reasons to manage it.

In electric racing, the brain of the car is the software – and that is where James sees the greatest room for advancement.

“As we are working with our drivers and engineers – and start to look at functionality to improve our efficiency and our performance, that’s something we’ll continue to push because that development is open throughout the season,” James said. “That’s going to be our focus going forward and provides enough of a challenge for us to get our teeth into.

“What’s going to be fascinating is as Formula E continues, is to really look at which areas of development on the car are going to be the most relevant and ensuring that we can focus on those together with the manufacturers so we continue and use the series as a platform for technical development that can then feed back into the road car side of things as well.

“At the end of the day, that’s what motorsports always been, a very powerful tool for, and I see Formula E as no exception.”

Selecting Rast and Hughes as McLaren’s Formula E drivers was not simply because they know how to drive fast. James believes both drivers have the mental aptitude to execute energy management strategies throughout the race and squeeze maximum performance.

“As with many other motorsports, you’ve got a certain amount of energy that you’re able to deploy during the race and the management of that energy is absolutely crucial,” James said. “What we’re seeing typically in electric motorsports now is the hardware side of things. The efficiencies that we’re seeing in the powertrain as a whole, they’re getting up to the sort of 96%, 97%, 98% efficiency, so the gains that you get through that further and further become more marginal.”

With much more room for improvement, software is a different matter. To make the best decisions, the drivers need data, and that is where James believes McLaren Formula E will make their greatest impact.

“And then you really switch that focus to the software and that’s where you’re going to see the most the most improvement and the most gains,” James continued. “It’s then using that software to ensure that you’re deploying the energy in the most efficient manner during race, and thereby giving the driver the most performance. And that’s something which is incredibly complicated, but I find it a fascinating area to work in.

“The benefit of being involved in racing is you can really push the envelope in a way that you can’t do on road cars. And I think that that’s where that value comes in. It means that you accelerate the development a lot quicker. We will get ahead of the curve – and we are getting ahead of the curve now – and that will mean that the electric motorsports remain part of the overall development process.

“The key to that is also making sure that the racing’s exciting and fun for the fans. If we can, we can tick both of those boxes, then it’s got a very bright future ahead of it.”
