iSport International set the pace on the opening day of the second GP2 Series post-season test at Barcelona's Circuit de Catalunya, with drivers Marcus Ericsson and Tom Dillmann ending the morning and afternoon sessions respectively on top.

It was Ericsson's morning benchmark that would be the quickest time of the day. The Swede raced for the Norfolk squad during his sophomore campaign in 2011, finishing 10th in the final standings with two podium finishes.

Dani Clos was second fastest, the Spaniard turning out for Scuderia Coloni having raced for Racing Engineering for the last three years. He was a tenth behind Ericsson, and a similar margin ahead of third-placed Esteban Gutierrez of Lotus ART.

The second Coloni car of Kevin Ceccon was fourth quickest in the morning, setting the exact same time as GP3 graduate Nigel Melker (Ocean). Dillmann was sixth, with Julian Leal seventh for frontrunning outfit Addax and Alexander Rossi eighth for Caterham Team AirAsia.

Kevin Magnussen was ninth on his debut GP2 appearance with Carlin, the same team with which he finished runner-up in British F3 this season. Jolyon Palmer completed the top ten behind the wheel for Addax.

Dillmann was more than half a second clear of the rest of the field in the afternoon session, but was still half a second shy of teammate Ericsson's morning time. Gutierrez was second, ahead of Melker, Rossi and Ceccon. Antonio Felix da Costa was sixth for ART, one place ahead of Clos.

Superleague Formula race winner Craig Dolby was making his GP2 debut for Arden, alongside F3 Euro Series champion Roberto Merhi. They finished the afternoon in eighth and ninth respectively. Ericsson ended up tenth in the afternoon.
