I have spent 26 Memorial Day weekends in the stands at the Indianapolis Motor Speedway. I have heard "Back Home Again in Indiana" while 300,000 people go quiet, and I have watched the field roll off behind the pace car more times than I can count. So when I went looking for a LEGO IndyCar to put on my shelf, I expected to find at least one. A Speed Champions car, a promotional set, something. There is nothing. LEGO has never made one.
That surprised me, and then it did not. IndyCar is a smaller property than Formula 1, and LEGO builds sets where the licensing and the audience line up. So this guide is the honest version. I will tell you exactly what you can and cannot buy, what the closest official option is, and how I approached building the Indianapolis 500 in brick when the box I wanted did not exist. If you want a LEGO IndyCar, the short answer is that you are going to build it. The good news is that is the fun part.
No. As of 2026, LEGO has never released an official IndyCar set, and it has never made a set based on the Indianapolis 500. I checked the current catalog and the back catalog, and there is no open-wheel Indy car in any line. There are fan-designed projects submitted to LEGO Ideas, including Indy 500 and Pagoda concepts, but a submission is not a product. None of them has crossed the threshold to become something you can order.
What LEGO does make is official open-wheel cars, just not IndyCars. The Speed Champions Formula 1 range, launched in partnership with Formula 1, includes single-seater race cars like the McLaren and Ferrari machines. Those are real, buyable, open-wheel LEGO cars, and they are the closest official thing to an IndyCar on the shelf today. They are not IndyCars. An F1 car and an IndyCar are built to different rules and look different in the details, from the aero to the cockpit protection. But if you want an open-wheel racer in brick without designing your own, a Speed Champions F1 car is where you start.
So the landscape breaks down into three honest options. One, buy a Speed Champions F1 car and accept that it is a stand-in, not the real thing. Two, use that F1 set as a parts donor and a scale reference for your own design. Three, go all the way and build a proper IndyCar MOC, which is a custom build made from scratch. Everything interesting about LEGO IndyCar lives in options two and three, so that is where the rest of this guide points.
Building a car nobody sells means you are doing the design work yourself. That sounds intimidating and it is not, as long as you respect the process. Every good custom build starts the same way it does for the pros, with reference material and a locked scale.
Gather references first. Pull photos of the exact car you want to build, from every angle you can find. Race broadcasts, paddock walkthroughs, and team media are gold, because they show you the details that a single publicity shot hides. You are looking for proportions before you worry about livery. Get the silhouette right and the sponsor colors will follow.
Pick a scale and never break it. This is the decision that makes or breaks a display. For a build that sits alongside minifigures and a larger Speedway scene, I use 1:38, where one LEGO stud stands in for roughly one real foot. At that ratio a real IndyCar, which is about six and a half feet wide, comes out close to six studs wide. That matters, because most people reach for a Speed Champions car as a reference and those are eight studs wide. Eight studs is eight feet at 1:38, which is too wide, and next to a scale building the car suddenly looks oversized. Getting the width right is the single check that validates everything else.
Design digitally before you buy bricks. I build every design in Stud.io, BrickLink's free digital design tool, before spending a dollar. You can verify that every part exists, that the connections actually hold, and that the parts list is affordable, all before a single piece arrives. Then you export instructions and a wanted list. If you want to see exactly how that pipeline works on a small, achievable subject, look at my IndyCar pit cart MOC. It is a custom design built in Stud.io and published on the BrickLink Gallery with free downloadable instructions. A pit cart is not a car, but it teaches you the whole workflow at low stakes, and it is the piece that turns a car on a shelf into a pit lane scene.
A car on a shelf is a car. A car next to a pit cart, on a base with track markings, beside the right building, is a scene. Scenes are what make people walk across the room to look closer.
A single car, even a beautiful one, is not the whole story of the Indianapolis 500. The car lives inside a place, and that place is what I have been building. The centerpiece of the whole project is the LEGO Indianapolis Motor Speedway build, my flagship MOC of the IMS Pagoda at 1:38 scale. Eleven stories, reverse-engineered from more than 150 reference photos because no floor plans for the building exist publicly. It is the anchor that every other piece is scaled and built around.
Around that anchor, the supporting builds fill out the scene. The pace car garage forms the ground floor of the Pagoda, with manual doors that open and a six-stud-wide pace car inside, the exact car that set the scale for everything. The Back Home Again jumbotron mosaic supplies the emotional iconography of the place, the message every fan knows, rendered in studs. And the pit cart drops in the pit lane context. Each piece shares the same design DNA: 1:38 scale, real-world reference accuracy, and a commitment to making the display feel like a facility rather than a row of objects.
That is the point I want to land for anyone chasing "LEGO IndyCar" as a search. The car is one element. The Speedway is the subject. If you build a car at the right scale, you have the start of something that can grow into a grandstand, a scoring pylon, a pit lane, and a Pagoda watching over all of it. The absence of an official set is not a dead end. It is an open field.
This is for the fan who has been to the track, or wants to feel like they have. If you have a favorite driver, a favorite era, or a favorite corner at Indianapolis, a custom build lets you put that specific thing on a shelf in a way no mass-market set ever could. It is also for the builder who is ready to move beyond following instructions and wants to design something from nothing. Reverse-engineering a car from photos is a different muscle than opening a box, and it is deeply satisfying.
It is probably not for you if you want something finished this weekend with no design work. In that case, buy a Speed Champions F1 car, enjoy it for what it is, and know that the IndyCar version simply does not exist to purchase. But if the phrase "you will have to build it yourself" sounds like a feature rather than a warning, you are exactly who this project is for. That is how the entire Speedway collection on this site started, with one stubborn idea on a long drive home from the race.
- The LEGO Indianapolis Motor Speedway build - the flagship IMS Pagoda MOC at 1:38 scale, and the hub of the whole IndyCar collection.
- The IndyCar pit cart MOC - a custom Stud.io design with free downloadable instructions, and the ideal first custom build.
- The pace car garage - the Pagoda's ground floor, with working doors and the car that anchored the scale.
- The Back Home Again jumbotron mosaic - the most emotional moment in motorsport, built in five colors.
- LEGO investing 101 - if you are wondering which bricks hold value, start here before you spend.
Frequently Asked Questions
Is there an official LEGO IndyCar set?
No. As of 2026, LEGO has never released an official IndyCar or Indianapolis 500 set. There are fan submissions on LEGO Ideas, but none has become a retail product. LEGO does make official open-wheel cars in its Speed Champions Formula 1 line, and those are the closest thing you can buy off the shelf. An IndyCar itself has to be a custom build, or MOC.
How do I build a LEGO IndyCar?
Start with reference photos of the car you want, pick a scale and stick to it, and design digitally in Stud.io before you buy a single brick. If you want a shortcut into the process, build a smaller context piece first, like a pit cart, then work up to the car and the surrounding scene.
What scale should a LEGO IndyCar be?
For a display that plays nicely with minifigures and the wider Indianapolis Motor Speedway build, 1:38 works well, where one stud is about one real foot. At that scale a real IndyCar is roughly six studs wide. Speed Champions cars are eight studs wide, so they read a little large next to a 1:38 building.
Can I use a Speed Champions F1 car as an IndyCar?
It is the closest official open-wheel option, and as a stand-in it is fine. But an F1 car and an IndyCar are different machines. F1 cars run a halo and complex aero, while an IndyCar has its own bodywork, its aeroscreen, and oval-specific setup. For accuracy you want a custom build, though an F1 set is a good parts donor and a solid scale reference.
Where can I get instructions for a LEGO IndyCar MOC?
Custom designs published on the BrickLink Gallery often include downloadable instructions and a parts list you can export to a wanted list. The IndyCar pit cart on this site is published that way with free instructions, and it is a good first step into building the rest of the scene.
