Robert Kubica completed a successful F1 test with his former team Renault at Valencia's Circuit Ricardo Tormo in June 2017.
Kubica celebrates third place at the Monaco Grand Prix in 2010. "There is no side to him -- he was never political, he just got on with the racing," F1 journalist Maurice Hamilton told CNN. "I think people just warm to him for being a very humble modest guy with massive talent."
Kubica was one of Formula One's brightest talents until his career was cut short by a rally crash ahead of the 2011 season. The Pole made his F1 debut for BMW Sauber (pictured) at the 2006 Hungarian Grand Prix.
Kubica was involved in a horror crash at the 2007 Canadian Grand Prix. After clipping Jarno Trulli, he collided with a barrier -- the speed of the crash was recorded at 186.49 mph.
Kubica escaped with only a concussion and sprained ankle but it was already the second serious crash he had been involved in. As a junior, the Pole was involved in a road accident that left his with a severely broken arm and multiple bolts to hold the limb in place.
Kubica's greatest triumph in F1 came at the same track and just a year after his 2007 crash, as he claimed victory in the Canadian Grand Prix for BMW Sauber.
After three full seasons with BMW Sauber, Kubica made the switch to Renault in 2010.
