Romain Grosjean got himself back up to speed with Formula 1 machinery this week by testing a 2009 Renault at Valencia, ahead of his travels to the final flyaway events as the team's official reserve driver.
The Frenchman, who won this year's GP2 Series, has not tested an F1 car properly since 2009, and he was given two days at Valencia this week in an R29 to once again get used to the power and handling characteristics of grand prix machinery.
Speaking after his run, having completed 372 miles, Grosjean said: "It is always fantastic to get back in an F1 car. The aim of the drive was to get me used to drive an F1 car again.
"We did some qualifying running in the morning and some long running in the afternoon. We also did some pit stop practices. It was very good for the fitness; I was very pleased and I did enjoy working with the team a lot. It felt different compared to 2009 because I am more experienced now.
"I enjoyed the car from the moment I jumped in and I enjoyed working with the engineers. We had a good time in Valencia and everybody enjoyed it."
