A respected F1 correspondent says Robert Kubica could get involved in Pirelli’s preparations for the new tyre rules for 2017.
The sport’s official supplier has already started work with a 2014 Ferrari driven by Jean-Eric Vergne at Fiorano.
And a GP2 car driven by Lotus refugee Pastor Maldonado at Mugello and Barcelona has also been in action recently.
Writing in the Finnish newspaper Turun Sanomat, Luis Vasconcelos reports that an invitation to drive "at least for one day" might now go out to Kubica.
Pole Kubica, now 31, rebuilt his motor racing career in rallying in the wake of his serious arm injury in 2011, and has admitted to missing formula one.
