The Indy Autonomous Challenge (IAC) is the main racing series for autonomous race cars. The vehicles participating in the IAC are SAE level 4 autonomous as they are capable of completing circuit laps and overtaking manoeuvres without any human intervention.

As a successor of the DARPA Grand Challenge, the IAC aims to provide a challenging environment for the development of autonomous vehicles. University teams are invited to develop software for solving the autonomous driving task, but in the challenging environment of a racetrack.

During the competition, teams test and prove the maturity of their algorithms as the race cars drive on track up to 290 km/h with high lateral and longitudinal accelerations.
