Williams chief Claire Williams has praised the 'remarkable' determination displayed by Robert Kubica as the Pole fought for seven years to get back on the Formula 1 grid after a career-altering rally accident, following the announcement yesterday he would be driving for the team in 2019.
In 2011, Kubica had part of his forearm severed in a rally car race, and subsequently had to undergo over a dozen separate surgeries to repair the damage.
It was thought his motorsport career would be over following the incident, but his rehabilitation has been incredible, and Williams believes his "fighting spirit" will only benefit the team as he gets behind the wheel again.
"He has a level of determination that is remarkable to see; and he truly embodies the Williams fighting spirit," the Williams boss said.
"Having the consistency of Robert stepping up into this new role will be an important step for us as we look to fight our way back towards the front of the field."
Kubica has claimed that, while the journey back to F1 driving level has not been easy, he is proud of the achievement of his recovery.
"It has been a challenging journey to make it back to the Formula One grid, but what seemed almost impossible is now beginning to feel possible," said the Pole.
"Being back on the F1 grid next season will be one of the greatest achievements of my life."
Kubica reportedly steps up from his reserve driver role with Williams thanks to significant financial backing, with oil and petrol company PKN Orlen sponsoring him for €10m.
