IndyCar COTA Open Test Entry List

| COTA 2019 winner Colton Herta |
Twenty-seven drivers in 25 cars are scheduled to converge on the Circuit of The Americas layout for a full-field open test Tuesday and Wednesday as the start of the 2020 NTT INDYCAR SERIES season looms just over a month away.
This event will mark the first full-field test of the new year and should prove beneficial to the drivers and teams when they return to COTA on April 24-26 for the AutoNation INDYCAR Challenge. The 17-race NTT INDYCAR SERIES season opens March 13-15 with the Firestone Grand Prix of St. Petersburg on the streets of St. Petersburg, Fla.
