Kubica testing with Mercedes simulator
Robert Kubica is testing with Mercedes on the Formula One team's race simulator as the Polish driver attempts a return following a serious rally accident two years ago, sources told DPA.
Kubica, 28, who raced for BMW and Renault in F1, has been testing on the simulator at the team's works in Brackley, England, according to dpa information.
There was no official confirmation from Mercedes with whom Kubica carried out tests in the winter in the Germany-based DTM series.
After four grand prix races this season, Mercedes are fourth in the constructors' championship.
Lewis Hamilton, who joined from McLaren, has twice been on the podium, while Nico Rosberg was on pole position at Sunday's Bahrain Grand Prix.
