Newly crowned GP2 champion Romain Grosjean returned to official driving duties with the Renault Formula 1 team in a straightline test at Duxford, UK. The Franco-Swiss drove throughout the test, which was used for aerodynamic evaluations as well as allowing the team's reserve driver to familiarize himself with the Renault R31.
"Yesterday was the third of four Aero test days which the FIA permit to carry out in-season," a team spokesperson told AUTOSPORT. "Following Bruno becoming one of our race drivers, we took the opportunity to acquaint Romain with the R31 as he is now our reserve driver. The day was spent evaluating present and future aerodynamic settings of this year's R31."
Although Grosjean has been officially designated as one of the team's "third drivers" since the start of the season, he has become official first reserve now that Bruno Senna has been promoted to a race seat. This means that he will attend the season-ending races and work closely with the team once the GP2 season has finished.
It is the first time that he has been on driving duty for the team in anything other than a demonstration run since his part-season with the team in 2009 came to an end at the Abu Dhabi season finale.
