Calls for an IndyCar race overseas only increased following news that NASCAR was set to head to Mexico City in 2025 for Cup Series and Xfinity Series races.
Now, Miles has offered an update on those talks, explaining that it is too soon for any announcements, potential races in Mexico and Denver were a work in progress.
"A new race isn't added until everything's done right, contracted for and all of that follows on us being convinced that we would have the right partnerships or promoters in the right markets," Miles explained to Autosport.
“It's too early to declare victory on any of the possibilities that you mentioned, but it is true that both of those markets are a work in progress.
"Look, if we land one of the two for as early as 2026 that'd be terrific, along with Arlington.”
If IndyCar did head to Mexico, it would be the first time the open-wheel championship has had a presence south of the border since 2007 during the Champ Car era.
