Honestly, if you haven't stood on the mounds at IMS during the month of May, you’re missing out on the purest form of motorsport. People get so hyper-focused on the Indy 500 that they completely overlook the Indianapolis Grand Prix 2025, which is honestly a mistake. It’s the appetizer that sometimes tastes better than the main course.
The Sonsio Grand Prix—as it's officially branded for 2025—is scheduled for Saturday, May 10. It’s the kickoff. It is the moment the engines finally scream at 16th and Georgetown after a long winter. Unlike the 500, which is all about left turns and terrifying average speeds of 230 mph, the Grand Prix utilizes the 2.439-mile road course. It’s technical. It’s leafy. It’s weirdly intimate for a place that holds 300,000 people.
What is actually different about the Indianapolis Grand Prix 2025?
Most casual fans assume Indy is just a big circle. Nope.
The road course runs clockwise, which is the "wrong" way if you’re used to the oval. It uses a chunk of the front stretch, then dives into a complex series of turns in the infield that were originally designed for Formula 1 back in the early 2000s. For the Indianapolis Grand Prix 2025, drivers will be wrestling these 1,600-pound machines through 14 turns.
There is no power steering in IndyCar. None. By lap 40, these guys have arms like Popeye.
If you’re looking at the 2025 schedule, this race serves a very specific purpose. It sets the tone for the entire month. Last year, we saw how momentum from the road course win can carry a team through the qualifying weekend for the 500. It’s about psychological dominance.
The New Hybrid Era at IMS
We have to talk about the power units. 2025 is the first full season where the 2.2-liter twin-turbo V6 engines are paired with the new hybrid energy recovery system (ERS) from the jump.
Basically, the cars have a "push-to-pass" button that now integrates stored electrical energy. It’s not just about a turbo boost anymore. It’s about harvesting energy under braking in the tight Turn 1 and Turn 7 sections and then dumping that power on the long back straightaway.
It changes the math for the engineers.
You’ll hear the commentators talking about "regeneration" and "deployment" more than ever during the Indianapolis Grand Prix 2025. If a driver mismanages their battery, they’re a sitting duck coming off Turn 14 onto the main straight. It adds a layer of strategy that wasn't there three years ago.

Where you should actually sit (Don't buy the expensive seats)
Listen, you can go buy a reserved seat in the stands. They’re fine. But the real pros at the Indianapolis Motor Speedway for the road course race buy General Admission.
Why? Because the mounds are incredible.
The mounds at Turn 1 and Turn 7 offer some of the best sightlines in all of North American racing. You bring a cooler (yes, you can still bring your own food and drinks to IMS, which is a miracle in 2025), a folding chair, and you park yourself under a tree.
- Turn 1 Mounds: You see the hardest braking zone. Cars go from 180 mph down to about 60 mph in a heartbeat. The smell of hot carbon brakes is intense here.
- The Hulman Terrace: If you want to spend money, this is the spot. You get a view of the pit exit and the dash to Turn 1.
- Turn 4/5/6: This is the "snakes" section. It's fast, flowing, and shows off the sheer downforce these cars produce.
The atmosphere is just... chill. It's not the chaotic, sun-baked madness of the 500. It’s a family-friendly day where you can actually walk around and see the cars from five different angles without fighting a crowd of a quarter-million people.
The 2025 Grid: Faces to Watch
The driver market for 2025 has been a bit of a localized earthquake.
Alex Palou is still the benchmark. The guy is a machine. He drives a race car like he’s doing high-level calculus in his head while drinking a latte. He’s won here before, and he’ll likely be the favorite for the Indianapolis Grand Prix 2025.
But watch out for the Arrow McLaren boys. Pato O'Ward is always a threat on road courses because his driving style is basically "controlled chaos." He slides the car in a way that shouldn't work, but it does.
And then there's the Penske factor. Roger Penske owns the track. He hates losing at his own house. Josef Newgarden and Scott McLaughlin have turned the IMS road course into their personal playground in recent testing sessions.
Is the "Month of May" still a thing?
Sort of. It’s changed.

Used to be, the track was open every single day for three weeks. Now, it’s more condensed. The Indianapolis Grand Prix 2025 on May 10 effectively opens the gates. After the checkered flag drops Saturday afternoon, the crews pull an all-nighter. They literally tear the cars down to the bare tub and rebuild them in "Oval Specification" for practice starting the following Tuesday.
It’s the most grueling turnaround in sports. You go from a high-downforce road course setup to a "trimmed out" oval setup where the wings are as thin as a piece of plywood.
Logistics: How not to hate your life on race day
Traffic at IMS is a legendary nightmare, but for the Grand Prix, it’s manageable.
If you’re coming from downtown Indy, take 16th Street. If you’re coming from the suburbs, try to hit the North 40 parking lot. It’s free (usually) and puts you right by the backstretch.
Pro Tip: Wear comfortable shoes. You will walk three miles minimum. The Speedway is massive. It’s so big you can fit the Vatican, the Roman Colosseum, and Yankee Stadium inside the oval and still have room for a golf course. Which, by the way, there is an actual Pete Dye-designed golf course (Brickyard Crossing) that runs through the infield.
- Check the weather. Indiana in May is bipolar. It will be 85 degrees at noon and storming sideways by 3:00 PM.
- Bring a scanner or a headset. You can’t hear the PA system over the engines. If you want to know why your favorite driver just pitted, you need to listen to the radio broadcast or the team comms.
- Visit the Museum. It’s currently undergoing renovations and massive updates for 2025, but the basement tours and the rotating exhibits are world-class.
The Economics of the Race
Let's be real—racing is expensive. But the Indianapolis Grand Prix 2025 is one of the few top-tier sporting events where you can get through the gate for under $50 if you plan it right.
Compare that to Formula 1 in Miami or Las Vegas where a soda costs $15 and a ticket is a mortgage payment. IMS remains the "People’s Track." You can bring your own beer (no glass!), your own sandwiches, and enjoy world-class racing without feeling like you’re being exploited by a billionaire's vanity project.
Why this race matters for the Championship
The IndyCar points system is flat. A win at the GP pays the same as a win at Barber or Road America.
However, the psychological weight is different.

If you win at Indy in May, you are the king of the paddock for two weeks. You get the momentum. Your sponsors are happy because they’re all in town for the 500. The media attention doubles.
We’ve seen it before: a driver who struggles in the Grand Prix often carries that "dark cloud" into 500 practice. Conversely, if you podium at the Indianapolis Grand Prix 2025, you walk into the garage on Monday morning with your chest out.
Actionable Steps for Fans
If you're planning to attend or watch, here is how you maximize the experience.
Buy your tickets early online. Don't wait for the gate. They’ve moved almost entirely to digital ticketing, and it saves you $10–$15 per person to buy in advance.
Download the IndyCar App. It has live telemetry. You can see the tire deg, the push-to-pass counts, and the live gap between drivers. It makes the race way more interesting when you can see that the leader is actually nursing a fuel issue that hasn't been mentioned on TV yet.
Stay for the support races. The Indy NXT series usually runs on Friday and Saturday. These are the kids trying to make it to the big leagues. They drive like they have nothing to lose, which usually results in some pretty spectacular (and sometimes messy) racing.
Walk the Fan Zone. Unlike other tracks, the IMS Fan Zone is actually decent. There are historic cars on display, driver autograph sessions (if you get there early), and plenty of merch that isn't marked up 400%.
The Indianapolis Grand Prix 2025 isn't just a "support race" for the Indy 500. It is a standalone, high-stakes tactical battle on one of the most famous pieces of pavement in the world. Whether you're a die-hard petrolhead or just someone looking for a reason to sit on a grassy hill with a cold drink, this is the weekend to do it. Just don't forget the sunscreen—that Indiana sun is deceptive until you're already burnt.
