Robert Kubica will be Alfa Romeo's Formula One reserve driver for the 2020 season, with Polish oil company and personal backer PKN ORLEN joining as co-title sponsor, the Swiss-based team said on Wednesday.
Kubica, 35, made his race debut with the team in 2006 when they were competing as BMW Sauber.
The Pole, who suffered a near-fatal rally accident in 2011, made his comeback with struggling former champions Williams last season. But he left at the end of the campaign, in which he scored the team's sole point.
"I'm starting a new chapter in my career by joining Alfa Romeo Racing ORLEN," Kubica said in a statement.
