Andretti Harding Steinbrenner Autosport was an auto racing team that competed in the IndyCar Series.

[2] Steinbrenner IV had previously run an Indy Lights program with childhood friend Colton Herta as driver, in a partnership with Andretti Autosport.

[5] Herta would win the second race of 2019, at Circuit of the Americas, but that did little to solve the team's continued budget issues.

[6] Rather than lose the young driver to the newly formed Arrow McLaren SP,[7] Andretti agreed to a deal that would see the HSR No.

[11] Barnhart would be credited with securing the partnership with Steinbrenner/Andretti and eventual merger with Andretti amidst the teams budget issues.
