Romain Grosjean Renault's reserve driver Romain Grosjean set the pace on the opening day of GP2 Asia series testing at the Yas Marina circuit in Abu Dhabi.

The Frenchman, who will race in the series with the DAMS team, posted the best time of the day in the afternoon following a very slow morning, during which there was very little running due to the track conditions.

A sandstorm on Tuesday meant the track was too dusty for any significant work to be carried out, and most drivers settled for installations laps. Conditions improved in the afternoon despite some early rain, however, and Grosjean emerged on top with a time that was around half a second quicker than his closest rival, Jules Bianchi in the Lotus ART car.

GP3 Series graduate Stefano Coletti, quickest in the morning, was third fastest in the afternoon with the Trident car, with the two Barwa Addax cars of Giedo van der Garde and Charles Pix completing the top five. The test continues tomorrow.
