The CW greenlit the show on December 6, 2022 as part of its demographic shift after its acquisition by Nexstar Media Group. The first season showcased behind-the-scenes look at IndyCar Series drivers preparing for the Indianapolis 500. The second season features Josef Newgarden alongside Marcus Ericsson, Pato O'Ward, Álex Palou and Kyle Larson. 100 Days to Indy is co-produced by Penske Entertainment and Vice World News.
