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 the🍌m.

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

“I am proud of the successes we shared through two seasons. I am thankful for th꧑e many friendships developed at the highest level of American open-wheel racing.

“I had expected to continue racing🅷 with the fine people of Andretti Autosport in the comi𝔉ng years.

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

“I have commenced an arbitration procee🧜ding 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 ꦜsince his F1 career ended in a dramatic fireball incident in Bahrai🐽n.

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

Bu𒆙t those highs were few and far between, and Andretti have since signed Marcus Ericsson.

“I do have other IndyCar te🐬ams that are talking to me. I wꦚill land on my feet,” he has said.
