2. Testing Vehicle Capabilities: Live testing of vehicle hardware and software in extreme conditions offers critical insights for academic research and invaluable feedback for industry partners.
3. Engaging the Community: The event seeks to generate excitement around autonomous mobility, appealing to local communities, government agencies, students, and industrial sponsors alike.

Underpinning Inspiration from DARPA

The IAC drew inspiration from DARPA's historic Grand Challenges two decades ago, which catalyzed the global autonomous vehicle industry, resulting in significant investments. DARPA recently participated in the IAC’s AI and Automation Summit, discussing initiatives aimed at transitioning autonomy from simulation to real-world environments, with IAC positioned as a key partner in these developments.

Rules of Engagement for the Race

The Speed competition features a 7-minute timed lap period, where the average speed of the fastest lap determines standings, without human intervention with the vehicles. Only IAC race control can signal using electronic flags to indicate race statuses:

• Green Flag: Timed laps have commenced.
• Yellow Flag: Caution is advised, speed should decrease.
• Black Flag: Return to the pits is required.

Format for the Passing Competition

This dynamic event sees two racecars competing head-to-head on the track. Competitors swap between attacker and defender positions, requiring a successful pass within a lap at progressively increasing speed levels. Key points include:

1. Initial speed set at 80 mph, incrementing by 10 or 5 mph in subsequent laps.
2. A failure to complete a pass or an accident results in elimination.
3. Teams are organized in a bracket system, with seeding determined by time trial results.

Meet the Racecars: IAC AV-24

The racing vehicles, designated as IAC AV-24, are constructed with a chassis from the Dallara, utilized in the IndyNXT Championship Series. Key modifications include:

• Installation of advanced robotics hardware and a computing stack.
• Integration of unique AI driver software developed by participating university teams into a central computer from dSPACE GmbH, part of the AV-24’s cockpit system.

The IAC AV-24 is recognized as the world's fastest autonomous vehicle, having set a remarkable land speed record of 192.2 mph at the Kennedy Space Center in April 2022, thanks to the AI driver developed by team PoliMOVE and the University of Alabama.

List of Competing Teams

• Cavalier Autonomous Racing (University of Virginia)
• PoliMOVE-MSU (Collaboration of Politecnico di Milano, Italy, Michigan State University, and University of Alabama)
• TUM Autonomous Motorsport (Technische Universität München, Germany)
• KAIST (Korea Advanced Institute of Science and Technology)
• Unimore Racing (University of Modena and Reggio Emilia, Italy)
• Autonomous Tiger Racing (Auburn University)
• Purdue AI Racing (Purdue University)
• AI Racing Tech (A consortium of Universities including California at Berkeley and San Diego, Hawaii, and Carnegie Mellon)
• IU LUDDY (Indiana University)

The Caltech team, a newcomer, has joined the ranks and plans to participate in the CES (Consumer Electronics Show) event in 2025.

Strategic Approaches to Racing

Since all racecars share identical hardware, the competitive edge lies in their software. Teams must develop algorithms capable of:

• Perceiving and interpreting the environment.
• Simulating vehicle-road dynamics.
• Determining car position accurately.
• Planning paths and controlling vehicle speed.
• Executing effective control decisions at speeds nearing 150-185 mph.

The immense volume of sensor data generated every second requires swift assessment and decision-making. To succeed in the passing competition, teams must evaluate other vehicles strategically, adapting to fluctuations in weather, track conditions, and wind resistance.

Teams have spent the last 12 months perfecting simulations and software, with the final two weeks dedicated to hands-on driving, data collection, and refining race strategies.

The Speed Challenge

The race takes place on a 2.5-mile oval track, where cars can achieve speeds around 150 mph, making an average lap about one minute long. With a maximum of 7 minutes, teams can anticipate completing about 7 laps. Initial laps are somewhat conservative, ranging from 130-145 mph, as tire warming is crucial for optimal traction. Laps subsequently progress to speeds between 160-185 mph.

During the speed segment, inclement weather interrupted proceedings after three teams completed their runs, necessitating track drying by service vehicles before racing could resume.

TUM seized the opportunity to race following the rain delay, showcasing an impressive average speed of 166 mph across the first five laps. Unfortunately, during their sixth lap, a sharp turn resulted in a loss of vehicle control, leading to a crash and necessitating a cleanup operation. Regrettably, this incident marked the end of TUM's competition, evoking deep disappointment for the team.

Outcome of the Speed Trials

The victory in this competition went to the Cavalier team from the University of Virginia, marking a historic first for a U.S. team. They achieved a top speed of 184 mph during their final lap, setting a new world record for the IAC. Dr. Madhur Behl, the project's lead and an Associate Professor of Computer Science, commented:

“This competition is fundamentally a ‘battle of algorithms.’ All the cars are nearly identical in hardware—sensors, chassis, engine, onboard computer. Winning comes down to building a superior AI driver that can push the boundaries of perception, planning, and control, operating right at the edge of what’s possible. Latency is a critical issue and requires innovation and system designs that are fast, robust, and predictive.”
