Hamilton quickest as rain halts day two at Ricard.

Lewis Hamilton set the quickest lap of a wet second day of GP2 Series testing at Paul Ricard, before increasingly heavy rain brought a premature end to the session and prevented anyone from challenging Nelson Piquet Jr's time from day one.

The Briton returned to the cockpit of the ART Grand Prix Dallara he is expected to occupy next season, raking up another 37 laps as he again paced the session, setting a 1min 28.173secs benchmark that no-one proved able to match.

Hamilton quickest as rain halts day two at Ricard.

Lewis Hamilton set the quickest lap of a wet second day of GP2 Series testing at Paul Ricard, before increasingly heavy rain brought a premature end to the session and prevented anyone from challenging Nelson Piquet Jr's time from day one.

The Briton returned to the cockpit of the ART Grand Prix Dallara he is expected to occupy next season, raking up another 37 laps as he again paced the session, setting a 1min 28.173secs benchmark that no-one proved able to match.

Piquet, who had snatched top spot on day one, proved to be Hamilton's closest challenger, but was three-tenths adrift of the Briton when the session was halted as a sudden deluge and the onset of thick fog called safety at the French circuit into question.

Olivier Pla was third fastest for DPR, the only other driver to duck below the 1min 29secs barrier, while Lucas di Grassi maintained his current good form with another strong showing in fourth place. This time, however, the Brazilian was driving for Super Nova International, having run with Durango on day one, and clocked the third fastest lap. As a result of his impressive showings no matter which team he has run with, the Macau Grand Prix winner would seem assured of a place on the grid alongside Hamilton, Piquet and Pla in 2006.

After taking a day out on Thursday, Ernesto Viso returned to the fray for a final fling before the Christmas break, claiming fifth for iSport International, one of the teams apparently on the Venezuelan's wishlist, alongside former employer BCN and others, for 2006. Rookie Andreas Zuber was sixth for the Spanish outfit, backing up the top five spot he took for Enrique Scalabroni on day one.

Luca Filippi took seventh for Coloni, which is being linked to a possible partnership with his former employer, Fisichella Motorsport, for next season, with Danilo Dirani underlining the latent competitiveness of Campos Racing with eighth place, backing up di Grassi's Jerez performance with the team.

Series veterans Alex Negrao and Ferdinando Monfardini rounded out the top ten, ahead of the impressive Mike Conway, who claimed eleventh spot on his first outing with DPR. The Briton had run strongly for iSport on day one, and suggested that he could be a potential frontrunner should he decide to step from F3 after just one year.

Behind Jose Maria Lopez, who returned to the timesheets with Racing Engineering after having every one of his laps deleted for a weight infringement on Thursday, Adrian Sutil made his first appearance in a GP2 car, having linked up with Super Nova. The F3 Euroseries runner-up headed Bruce Jouanny and Hayanari Shimoda in the top 15, with Kiwi Matt Halliday taking 16th on his GP2 debut.

The F1 feeder series now takes a break from the rigours of testing until the New Year, when the first 26-car GP2 series test takes place following the creation of a 13th team entry for Trident Racing.
