Robert Kubica sees “no reason” to cut short his return to Formula 1 despite the lack of success he and Williams have experienced so far.

The team has been the slowest at every race so far this season. Kubica is yet to out-qualify his team mate George Russell and his finished behind his team mate in all but one of the nine rounds so far.

When asked by RaceFans in Austria, Kubica said it is “too early to say” whether he would commit to a second season in the sport. He dismissed suggestions he could end his comeback before then, saying he “sees no reason” to do so.

Last week’s Austrian Grand Prix marked a new low for Kubica, who took the chequered flag almost a full minute behind Russell. He said the race had been a continuation of the problems he has endured all season.

“It’s difficult to comment when you finish three laps down and nearly lapped by your team mate,” said Kubica.

“The comments are the same as always. I am sliding whenever I am putting too much stress into the tyres, I have no grip, and even if I try to keep up the pace I am able to do it maybe for two, three laps and then the tyres are overheating and sliding.

“I was even sliding at the exit of turn seven which is a fifth, sixth gear corner. Then you can imagine it’s pretty difficult to extract anything if you are just sliding and degrading.

“Whenever you put more slip into the tyres you go slower. So I have to drive to don’t slip them but then the pace is very slow.”
