Kvyat calls for rethink over kerb design

The Toro Rosso became the fourth driver to suffer a suspension failure so far over the Austrian Grand Prix weekend when his right rear failed on his final lap in Q1.

He was pitched into a spin, swiping the tyre barrier at the end of the pitlane entry and ending up hitting the wall at the outside of the final corner.

Speaking to Sky after the incident, Kvyat said that the run of failures shows that something has gone amiss with the kerb design.

"Once you're on those kerbs you're not in control if the suspension breaks. At least on the AstroTurf, you had control," said the Russian.

"At the last corner, everyone is going off [with] four wheels, they wanted to make it better but actually they made it worse.

"I think this year the track needs a bit of review, because the track limits is an issue and these kerbs are not very cool, and they are very dangerous actually."

Weird incident

Kvyat said that the nature of his crash had caught him by surprise as it was not the first time that he had run wide at that section of the track.

"I don't know what happened there," he said. "When I went on those kerbs earlier I lost some laptime, but this time the suspension broke, very weird, and it steered me to the right.

"Already on the first run we had a puncture, I don't know what was going on really, we have to investigate if it's the kerb or something related to the puncture from before.

"The problem is that a different suspension broke, not the one that was on the kerb, the one that was outside the kerb broke."
