This morning's cooler temperatures meant improved track conditions and lap times at Jerez de la Frontera.

The second day of GP2 Series winter testing saw a major reshuffle as only nine drivers ran in the same car they ran in did yesterday, namely Oliver Turvey (iSport), Luiz Razia (Piquet GP), Rodolfo Gonzalez (Arden), Ricardo Teixeira and James Jakes (Super Nova), Sam Bird (DAMS), Francesco Castellacci (Durango), Philip Eng (Ocean Racing) and Michael Herck (DPR).

Ten new racers entered the entry list for today's session with some names well-known to the GP2 circus, names such as Kamui Kobayashi, Dani Clos and Alberto Valerio) and some rookies (Marcus Ericsson, Sten Pentus, Jan Charouz, Filip Salaquarda, William Bratt, Fabio Leimer and Vladimir Arabadzhiev.

But it was the more experienced drivers who set the pace this morning, led by Giedo van der Garde (Barwa Addax Team) clocking in the best lap time of a 1:25.291 and over a tenth clear of Valerio driving for Party Poker Racing.com SC. Behind them, Kobayashi - fresh back from running with the Toyota F1 team in Suzuka last Friday during the free practice sessions Formula One Practice sessions 1 and 2 - at the wheel of Fat Burner Racing Engineering car was also on good form and completed the top three.

Once again, the temperature rose in the afternoon and the morning lap times could not be improved. In a trouble-free session, Kobayashi topped the times two tenths ahead of Jerome d'Ambrosio - who joined ART Grand Prix today - and five tenths clear of this morning's quickest man on track van der Garde. However, the Dutch driver topped the combined times for the day.

With a lap time of a 1:25.575 set this morning, German Christian Vietoris at DAMS was the fastest rookie of the day.

The three-day session will conclude tomorrow with five times WRC Champion Sebastien Loeb joining DPR.
