While F1 is taking a bit of a break, the GP2 teams will be back in action this weekend and holding the second consecutive round of races at the Bahrain International Circuit at Sakhir.

The chief differences for the GP2 teams this time around are that they'll be operating from the main pit lane complex now that the F1 teams no longer need them; and that the schedule no longer needs to fit around the Grand Prix practice and qualifying track activity.

This week's GP2 practice and qualifying still take place on Friday, but are being condensed into the morning (at 7.55am and 9.25am BST) so that the feature race can be brought forward and run on Friday afternoon (1.55pm BST). The sprint race then follows on Saturday at 11.55am BST, allowing the teams to take their leave on Sunday.

The big challenge for the GP2 teams other than DAMS is to see whether they can do anything about the irresistible form of championship leader Davide valsecchi, who dominated last weekend's event. After dominating practice and qualifying, we romped home to a feature win and then followed it up with a hard-fought victory from an eighth place start in the sprint place.

"It's the best weekend of my career!" said a jubilant Valsecchi, looking back. "A big thanks to the whole team who gave me a fantastically well-prepared car for practice and the races with an impeccable pit stop.

"I fought hard to achieve this," he added. "With the DAMS team I can fight with the best and we're going to make sure this continues."

"A double during the same weekend is very rare in GP2 and everybody, engineers, drivers and mechanics, did a great job," said DAMS CEO Jean-Paul Driot. "Bravo to Davide - and also to Felipe who made an exceptional comeback on Sunday. However, it's only the start of the championship and we're fighting top-class rivals. We're staying fully concentrated on the coming races."

Valsecchi's double top means that he surged ahead of Arden's Luiz Razia in the championship, and the Brazilian is determined to fight back this weekend.

"Clearly we still have some work to do to narrow the gap to DAMS," he said. "The tyres are incredibly sensitive and tiny set-up alterations can make a difference of a few seconds over a race distance." He called last week's races "another encouraging weekend" and added: "It was a good result, but a difficult race."

After two rounds so far in 2012, only two teams have failed to score any points so far this season - Trident Racing is one, while the more surprising is Barwa Addax - the 2011 GP2 championship-winning team. Where has it all gone so wrong for the Spanish team that performed so strongly last year with Giedo van der Garde and Charles Pic?

"I can't wait for the next race," insisted lead driver Johnny Cecotto Jr., who exited last weekend's feature race after a clash with Valsecchi's rookie DAMS team mate Felipe Nasr, and then hit with a jump start penalty in the sprint race. "This time I know the track. Without the errors we committed in the first round in Al Sahkir, we can for sure manage a podium - if not even more."

Cecotto will once again be joined in the team by experienced Spanish driver Dani Clos, who replaced Josef Kral in advance of last week's race. "After the last intense weekend and all the efforts of the team, I now feel more confidence with the car," said Clos. "I am looking forward to fighting for the top positions.

"I know the tyres better and how to deal with them," he continued. "It is very important to have a good strategy and save tyres to face the last laps with no problems. I hope we have more luck this time and have clear hot laps to achieve a good result in the qualifying."

It's unclear whether Clos will continue to run any more races for Addax after this coming weekend. Clos has to prioritise his regular role as HRT's third driver in F1, and in any case Addax would need to see some immediate results being delivered this weekend to persuade them to keep the 23-year-old on for more outings.

"I am very glad to be with Barwa Addax Team and I am quite sure we will make a good job together," insisted Clos.

Brendon Hartley is also scheduled to continue driving the Ocean Racing Technology #24, although the team is hopeful that previously announced driver Jon Lancaster will be able to sort out his sponsorship backing and return to the cockpit soon, possibly in time for the next GP2 round in Spain on May 11-13.
