Romain Grosjean will compete in a select number of IndyCar races this season for Dayle Coyne Racing.
Grosjean made the announcement just over two months after his miraculous escape from a burning wreckage at the Bahrain Grand Prix. The French driver, who has explained in detail how he thought he was going to die while inside the car, was left with burns on both hands.
The crash forced Grosjean to miss the Abu Dhabi Grand Prix, which would have been his final race in F1 after Haas decided not to renew him for a sixth season.
Grosjean will return to racing this season at the IndyCar opener at Barber Motorsports Park on April 18, just a day after he turns 35. His contract will only include all 13 street and road course races in 2021, meaning he will not contest oval races as a rookie.
He will complete his first test for the team on February 22.
