The corkscrew flip at Laguna Seca Raceway was the positioning of a number of overtakes at this 12 months’s autonomous race. | Credit score: IAC
The most recent Indy Autonomous Problem, or IAC, college race happened on Sept. 3, previous to the annual Grand Prix of Monterey weekend. This 12 months’s occasion featured the primary time in IAC historical past that the autonomous racecars overtook each other on a street course.
The successful workforce was Unimore Racing from the College of Modena and Reggio Emilia. The ultimate warmth featured a race between Unimore and Purdue AI Racing.
9 college groups from North America, Europe, and Asia competed on this occasion, with their AI driver software program piloting AV-24s offered by IAC. The group has held six passing competitions since 2022, all on oval tracks, together with the historic Las Vegas Motor Speedway, Texas Motor Speedway, and Indianapolis Motor Speedway.
I attended the 2025 IAC occasion at Monterey, the place the IAC demonstrated autonomous car racing on a street observe for the primary time in North America. At that occasion, the groups competed for the quickest lap occasions, with just one car on the course at a time.
One-on-one heats characteristic overtaking
This 12 months’s competitors consisted of one-on-one heats by which the overtaking automobile had two laps to overhaul the lead car. The groups then swapped positions and elevated the ability limits for the engines.
Whereas on target, the AI drivers made the entire choices about when and the place to go on the race course, as soon as the warmth began. The human crews monitored car information and will tweak the parameters earlier than the beginning of the subsequent overtake lap. Additionally they saved their fingers on the e-stop button in case of a malfunction or collision.
Many of the work for every workforce occurs away from the observe, the place the groups modify and check the AI driving algorithms in simulation all through the remainder of the 12 months.

The groups certified for the occasion a couple of months earlier, in a simulation race event hosted by D-Space. That is the primary time that taking part groups have been required to qualify for an autonomous race inside a digital testing setting earlier than being allowed to compete on a bodily observe.
The IAC occasion is primarily an AI driver software program occasion, because the autos all have the identical Dallara base design, Honda engine, Luminar sensors, and NVIDIA GPU.
Throughout the D-Area software-in-the-loop setting, the groups validated car conduct, race technique, and overtaking efficiency in a practical digital twin of Laguna Seca raceway. This ensured that any algorithm anomalies wouldn’t result in an on-track collision leading to harm to a race automobile.
The groups sometimes encompass Ph.D. and grasp’s college students, all of whom are engaged on autonomous driving or vehicle-related analysis. The IAC occasion began in 2021 on the Indianapolis Motor Speedway, with a world lineup of college groups.
Every workforce is supported by sponsors and donors within the automotive and bodily AI market, because the analysis and occasion straight affect the tempo of innovation for autonomous driving, based on the IAC.
A number of workforce members have began new corporations within the automotive area after finishing their analysis applications and dealing with the IAC race program. Examples embrace Aidoptation, driveblocks, and Autonoma AI.
