Grosjean reckons puncture led to collision
13 November 2017 – Romain Grosjean believes that a puncture from Turn 1 contact led to his collision with Esteban Ocon on the first lap of the Brazilian Grand Prix.
Haas driver Grosjean lost control of his car through Ferradura, while running side-by-side with Ocon, and slid into his Force India rival.
Ocon suffered terminal damage, and pulled off track later in the lap, with Grosjean going on to place 15th out of 16 finishers, two laps down.
Grosjean claimed that his car took a hit at Turn 1, with start replays showing that his rear-left tyre was tagged by Stoffel Vandoorne's front wing.
He was nonetheless given a 10-second penalty by the stewards, which he reacted to with surprise over the team radio when informed by his engineer.
Reflecting on events, Grosjean commented: "The only thing I can say about the opening lap is that I got massively hit in Turn 1.
"I believe I had a puncture on the rear left; I got to Turn 6 and lost the car, and I think it was just the puncture.
"Getting a penalty on top of that – I'm not super happy with it."
Ocon suffered his first retirement in Formula 1 as a result of the contact, and his first in single-seater racing as a whole since 2014.
"I knew this day would come at some stage, but I wasn't expecting it to be [here]," he said.
"There was nothing I could do; Romain lost the car in Turn 6 and crashed into me. He made a mistake and I suffered from it.
"My front wheel rim was damaged, so I couldn't even drive back to the pits.
"It's frustrating because the car was quick."
