Di Grassi sought to race in Formula One in 2009 with Renault and speculation arose in the motor sport press over him replacing fellow countryman Nelson Piquet Jr. after the latter's poor performance compared to his teammate Fernando Alonso. Renault looked at running either di Grassi or fellow test driver Romain Grosjean for the season, but eventually chose to keep Piquet and Alonso. He along with the 2008 GP2 Series runner-up Bruno Senna were strongly considered by Ross Brawn to drive for Honda. The pair tested the Honda RA108 at the Circuit de Catalunya in mid-November which had di Grassi lap within half a second of Senna's pace. After Honda withdrew from Formula One due to the global financial crisis, Brawn elected for experience over youth by retaining Rubens Barrichello.
