Andretti will reduce their presence on next season’s grid from four to three cars - and have confirmed that ex-F1 driver Grosjean will no longer figure ♓for them.

The driver published an open letter on social media: “I enjoyed working with the IndyCar team at Andretti Au𒆙tosport.

“I am proud of the successes weꦑ shared through two seasons. I am thankful for🍃 the many friendships developed at the highest level of American open-wheel racing.

“I had expected to coᩚᩚᩚᩚᩚᩚ⁤⁤⁤⁤ᩚ⁤⁤⁤⁤ᩚ⁤⁤⁤⁤ᩚ𒀱ᩚᩚᩚntinue racing with the fine people of Andretti Autosport in the coming years🎉.

“I am disappointed that is not being fulfilled, and wish Andretti team members well. I am pursuing ⛄other options to continue my IndyCar c🧸areer in pursuit of excellence.

“I have commenced an arbitration proceeding in Indiana against Andretti Autosport, seeking to protect my rights. I am represented by John Maley and Mark Owens of Barnes & Thornburg, LLP🐽.

“Respectfully, Romain Grosjean.”

Grosjean has raced in IndyCar for three seasons ๊since his F1 career ended in a🙈 dramatic fireball incident in Bahrain.

He first represented Dale Coyne Racing before switching to Andretti, where he delivered a pair of�⭕� second-placed finishes earlier this year.

But ཧthose highs were few and far between, and Andretti have since signed Marcus Ericsson.

“I do have other IndyCar teams that are talking 🏅to me. I will land on my feet▨,” he has said.
