Vettel not sure what happened during Singapore GP start clash

Vettel, Verstappen and Kimi Raikkonen came together on the run away from the grid, with Raikkonen's car then collecting Verstappen and Alonso's McLaren at Turn 1.

While the three leaders were out on the spot, Alonso tried to continue after the resulting safety car, but his McLaren was too damaged and he had to retire.

Vettel, who was on the outside and moved over to cover the inside line as Verstappen and Raikkonen approached on his left, said it was not clear what had happened.

"I don't know, I didn't see that much," Vettel told TV crews when asked to describe the accident.

"I had an average start and then went to the left trying to fend off Max and the next thing I get a bump on the side and see Kimi's car.

"That's how this business is, and we'll move on. It doesn't change much."

Vettel made it through the first corner without getting collected by the other cars involved, but he then crashed out of the lead when he spun on the run out of Turn 3.

"I think there was damage on the car already," he said of his second incident.

"The cooler was broken and massively bent so we lost all water pressure.

"Not ideal, is it. We're not in the race and that's a pity, we can't show the pace we have.

"It's a long race but we are on the wrong side of the track so that doesn't help.

"There's nothing we can do now. But I'm sure there'll be more opportunities."

The FIA has said the incident will be investigated after the race.
