Paul di Resta has apologised to Force India after crashing out of the Korean Grand Prix.
Di Resta lost the back end of the car at turn 12 and hit the barriers.
It was the fourth successive race where the Brit has retired due to accident damage.
He was hit by Pastor Maldonado in Belgium and made errors under braking on the first lap in Italy and towards the end of the race in Singapore.
“I have to hold my hands up and apologise to the team,” said di Resta.
“Maybe I took a little bit too much kerb and that’s sent me off the track.”
“The way we’ve set the car up means it has been quite edgy and difficult to drive, and that’s what has caught me out today, although whether it has cost us points is hard to say.”
“The performance in the race was not where we wanted it to be and the front tyres were wearing out too quickly. So we need to have a rethink ahead of Suzuka and go there determined to have a clean race.”
