The Polish driver is a former Grand Prix winner
At his peak, Robert Kubica was one of the rising stars of Formula 1.
The Polish driver spent five seasons in Formula 1 from 2006 to 2010, before a crash almost ended his career. Taking part in a Rally in Andorra in 2011, the driver crashed into a road barrier which pierced the car.
Kubica lost past of his forearm, breaking an elbow, shoulder and leg. Despite three podium finishes the year before, Kubica never set foot in a Formula 1 car again.
That is, until Tuesday. Kubica returned to Renault F1 to take part in a private test, where the team revealed he "had the biggest smile on after his 115 laps".
Kubica has remained involved in motorsport since his crash, racing in the World Rally Championship where he had eleven top-10 finishes over four seasons.
The return of Kubica to Formula 1 has heightened the chances of him potentially returning to the sport. A former winner of the Canadian Grand Prix, Kubica's test with Renault may add pressure on their drivers.
Nico Hulkenberg has scored 14 points this season, but Jolyon Palmer has yet to earn any Championship points in 2017.
