F1's Wehrlein explains violent Race of Champions crash with Massa

The crash happened at the finish of their group race, as Massa just beat Wehrlein to the finish line in Polaris Slingshot three-wheelers.

Wehrlein clipped the TecPro barrier that separates the two lanes of the finishing straight, which appeared to jam his steering wheel on full right lock.

That sent him careering into Massa and launch his car into a roll that ended with it leaning on a barrier.

Both Wehrlein and his passenger got out unscathed.

"Somehow I touched Felipe at the end of the straight and I drove over his tyre I think and that's why we flipped," said Wehrlein.

"But the most important thing is that we're both OK, everyone is OK.

"It was definitely a shock.

"I hit the barrier first with the front right and that launched me into Felipe.

"Probably I looked too much at Felipe and that's why I hit the barrier."

When asked if he was shaken up, Wehrlein replied: "No, I wasn't shaken, the speed is not too fast.

"At the end it's still a shock, but the most important thing is we're both OK."

Massa admitted he had been "scared" the accident would cause injuries as it unfolded.

"We just finished the race, we had to go straight and I was on my line," he said.

"Maybe something broke on his car, because he moved to my line.

"He bounced really massively - a big accident."
