Kubica close to giving up F1 dream

Robert Kubica has suggested he will give up on his dream of returning to Formula 1 if he cannot secure a spot on the grid in 2019. Kubica has served as Williams' test and reserve driver this year and has been linked with a race seat at the British team when Lance Stroll leaves for Force India.

Kubica has not raced in F1 since suffering life-altering injuries in a rally crash in 2011, but an incredible return to the top step of motorsport has come close in 2018.

Stroll could still leave Williams before the season is through, which would leave Kubica in pole position to take over and potentially prove his worth for 2019.

But the Pole says time is running out on his hopes of making a dream comeback.

"I spent a lot of time and effort to have a chance and the priority would be to be on the starting grid in Australia," he said.

"But if this doesn't happen I would consider some different championship or different role. As I said, now I'm focused on trying to get a chance.

"When you don't do it for long time or you do it like I do it, every three months, it's normal that you have to go through different phases in order to get back your rhythm, get back feelings as natural as possible.

"I would have so much time in the car [if he had raced this season], there would be no more question marks about myself."

Kubica turned down reported interest from the World Endurance Championship in 2018, but says the series could be of interest if he is not chasing F1.

"It is completely different racing, a completely different category," he said. "It might be a good challenge.

"I saw it with rallying, OK, rallying is completely different than racing, and endurance races, they have more similarity to let's say F1, but still it is a different category.

"I think new challenges are nice. There is always some extra that gives you boost to go there and to see how you perform."
