It has been eight years since Robert Kubica last stepped in an F1 car in racing conditions. The Polish driver has worked hard since his rally accident to get back in the cockpit once again.

Now, in 2019, he will finally realise that dream and be able to race. However, even he is starting to doubt himself. Kubica has confessed that he is “20%” ready to make his comeback to competitive F1 racing.

The 34-year old believes that Williams’ struggles over testing in Barcelona is partially to blame for that mindset.

Speaking to the media after the final day of testing, he said “That’s the situation, I cannot change it.”

“I have to make sure we are doing everything what we can, from my side.”

“Coming back after eight years, probably I know 20 percent of the things that I should know before going to Australia.”

“The rest is unknown. I haven’t done longer than 15 laps long run. There is a lot of question marks. But that’s the reality, we cannot change it.”

The Polish veteran had a positive day of testing on Wednesday. However, the following day was a different story, full of frustration. He was unable to complete the desired laps of their testing programme due to a lack of spare parts.

“My last real run when I feel the car well was [Wednesday] afternoon, first run, when the car did things which I was surprised [by], a really nice surprise.” he continued.

“So I get up really a lot of confidence, but since then my confidence disappears, because the car was not in the right state”

As a result of their testing gremlins, including, but not limited to their car being late, Kubica is aware that assessing the car’s fitness is their target for Melbourne.
