Kubica delight at edging closer to incredible F1 comeback
Robert Kubica insists he can still complete a remarkable sporting return despite being overlooked for this year's Williams drive.
Kubica, the 33-year-old Pole who last competed in Formula One more than seven years ago following a life-threatening rally crash in 2010, tested for Williams in the hope of landing a full-time seat.
But the famous British outfit, which has won 16 championships, have instead opted for Russian rookie Sergey Sirotkin to partner Lance Stroll this term.
Kubica's omission has been softened by the role of reserve and development driver.
Kubica took part in three tests for Williams - he was slower than Sirotkin in the decisive final shootout in Abu Dhabi last November - and he also drove on a number of occasions for Renault last year.
The French team, however, had reservations over the Pole's fitness - particularly the right arm which he nearly had amputated following his rally crash - and opted to sign Carlos Sainz instead.
Kubica said: "My ultimate goal remains to race again in Formula One and this (move) is another important step in that direction. I cannot wait to get started.
"I have enjoyed being back in the Formula One paddock and I now look forward to working with the Williams technical team.
"I feel in the best physical shape that I have ever been."
