Robert Kubica has been confirmed as Alfa Romeo’s reserve driver for the 2020 season with his backers PKN Orlen joining as the team’s co-title sponsor.

Kubica returned to Formula 1 in 2019 with Williams eight years on from his near-fatal rallying accident that left him with severe injuries.

However, it proved a difficult comeback for the Polish driver as he was overshadowed by rookie team-mate George Russell despite scoring Williams’ only point of the season.

Having parted ways with the Grove team, Kubica will now link up with Alfa to offer his experience, turning down a simulator role with Haas and Racing Point.

“I am really happy to be starting this new chapter in my career as I join Alfa Romeo Racing ORLEN,” said Kubica.

“This team holds a special place in my heart and I am pleased to see some faces still here from my years in Hinwil.

“Time and circumstances are obviously different, but I am convinced that I will find the same determination and hunger to succeed. I am looking forward to helping Alfa Romeo Racing ORLEN make the next step forward.”

The 35-year-old previously raced for Alfa under its BMW-Sauber guise for four years, the outfit handing him his F1 debut in 2006.

He would go on to take Sauber’s sole victory during its 25 years in the sport, leading home a one-two finish at the 2008 Canadian Grand Prix.

Alfa, who revealed the PKN Orlen deal is a “multi-year partnership”, has an unchanged driver line-up in 2020 of Kimi Raikkonen and Antonio Giovinazzi.

Commenting on Kubica’s arrival, team principal Frederic Vasseur said: “We are delighted to welcome Robert back home and we cannot wait to start working with him.

“He is a driver that needs no introduction: one of the most brilliant in his generation and one who displayed the true meaning of human determination in his fight to return to racing after his rallying accident.

“His feedback will be invaluable as we continue to push our team towards the front of the grid.”
