He was later involved in a career-derailing rally crash in 2011 that almost severed part of his right arm, but has since bounced back, winning the 2013 WRC2 championship, and competing in the WRC in 2014.
There, as well as Renault reserve driver Sergey Sirotkin, he is reportedly scheduled to test the Enstone team's 2012 auto, which competed in F1 as Lotus.
Kubica, 32, completed 115 laps in the Lotus E20, the auto used by the Renault team under its previous Lotus guise in the 2012 Formula 1 championship.
Kubica initially returned to competition in rallying, winning the 2013 title in the World Rally Championship's WRC2 class and the '14 European Rally Championship season-opener.
Since then, he has contested the World Rally Championship, driven in GT events and was set to make a full return to circuit racing this season in the World Endurance Championship with the ByKolles LMP1 squad before pulling out on the eve of the first race.
"So guys. we need to come clean about something".
Renault revealed the test had taken place on Tuesday in a series of posts on Twitter. It's true. It really is Robert Kubica. "It was a private test, for Robert", the team said, adding that the Pole had completed 115 laps with "the biggest smile" afterwards.
And this Tuesday he'll be back in the cockpit of a Formula 1 machine.
