Colton Herta and Patricio O'Ward will move up to the IndyCar Series in 2019 as drivers for the newly formed Harding Steinbrenner Racing.
Harding Racing and Steinbrenner Racing announced the decision to join forces on Wednesday.
Harding Racing is owned by Indianapolis businessman Mike Harding and just completed its first IndyCar Series season. Harding is also owner and CEO of Harding Group, an asphalt and concrete contractor.
Herta and O'Ward made their IndyCar debuts in last weekend's finale at Sonoma Raceway.
Steinbrenner Racing is owned by George Michael Steinbrenner IV, the grandson of former New York Yankees owner George Steinbrenner. Steinbrenner Racing competed in Indy Lights last year. It had teamed with Andretti Autosport in Indy Lights competition with Herta as its driver.
