Robert Kubica has confirmed reports that he has driven in the Mercedes simulator but refused to give details.
Making a return to motorsport following his horrific accident in February 2011 in which his forearm was partially severed, the Polish driver has taken to rallying.
This past weekend Kubica contested the Rally Azores, which he finished in sixth place after a double barrel roll on Friday.
However, prior to the rally, the 28-year-old spent time in Mercedes' F1 simulator.
"I can say yes, I was there," he told Autosport. "But I cannot say how many times or how many laps I did. But there is this rumour to which I say, yes, I was in the Mercedes F1 simulator in the past."
Reports of Kubica's run in the simulator became public after he was spotted by a F1 team member at Heathrow airport on his way to Merc's Brackley base.
Asked if he would be back in the simulator any time soon, he added: "Maybe, I don't know.
"But it's not that every time someone sees me at Heathrow airport I am going to Mercedes. I am also at Heathrow for different reasons, it doesn't always have to be a connection with that."
