In the 2020 Indycar season Colton Herta drove the #88 Dallara DW12 – Honda for Andretti Harding Steinbrenner Autosport. The entry resulted of partnership between Andretti Motorsport with Harding Steinbrenner Racing, the team of businessman Mike Harding and George Michael Steinbrenner IV, which was an independent entrant in 2017-19. The car was backed by Capstone Turbine Corporation, the world’s leading producer of low-emission microturbine energy systems. In his second Indycar season Herta proved to be one of the leading series drivers. He won the Honda Indy 200 at Mid-Ohio, and scored six more top-five finishes. He ultimately finished the season 3rd.
