In 2011 December, Red Bull was confirmed that Vergne would race for Toro Rosso in the 2012 season, alongside fellow Red Bull Junior Team member Daniel Ricciardo and at the end of 2014, he was dropped by the Red Bull family.
On 19 December 2014, Vergne would join Ferrari in 2015, as test and development driver particularly in respect of simulator work. He left Ferrari in February 2017.
Explaining what happened at the end of 2014, Vergne told Crash.net: “In the summer I got a call from Red Bull saying that they would put Max in the car. Back then, I totally understood it.
“It was like, okay, Toro Rosso is some kind of school for the Red Bull junior drivers and there was no place to go to Red Bull, so actually it was kind of them to let me know so early in the season.
“But during that call, I said: ‘What if Vettel goes?’. The French speedy said: ‘You will be in the car’.
“I had done a great season so far, it was good. They knew the deficit I had against Kvyat in the car, talking about the weight [disadvantage]. Later on, when Vettel left, it was after my good races that I had done. But I found out later that because the way it was said, it would have looked bad that they’d come back on that decision.
“It was a frustrating situation, definitely. Then the whole Toro Rosso team wanted to keep me next to Max, and at the end of the day, it was the same outcome. They would not go back on the decision.”
