All teams from the
2009 GP2 Series season except for
Racing Engineering were due to take part, with the thirteenth slot being filled by
MalaysiaQi-Meritus.com.
Durango withdrew from the season for financial reasons. The season was the last to use the first specification of the
GP2/05 car, as used in Europe between
2005 and
2007.
Davide Valsecchi of
iSport International won the drivers' championship title, clinching it with three races to spare, in
Bahrain after a comprehensive performance in the first five races, winning a race at each of the first three meetings with two seconds before clinching the title. He added a fourth second place at the final round, to seal a 27-point championship-winning margin. Second place was settled by a tie-breaker between a pair of Italian drivers,
MalaysiaQi-Meritus.com driver
Luca Filippi and
DPR's
Giacomo Ricci. Despite not scoring in any of the sprint races to be held, a win and two second places in feature races for Filippi compared to six top-five finishes – including a first GP2 win at the final Bahrain race – for Ricci allowed Filippi to take the runner-up spot.
Arden International drivers completed the top-five placings with
Javier Villa fourth despite missing the first meeting at Abu Dhabi, and
Charles Pic fifth, the only other driver to win a race during the campaign, winning at the first Bahrain meeting. In the teams' championship, iSport won the championship with two races to spare, after the points amassed by Valsecchi and
Oliver Turvey put them out of reach of their rivals. Second place, 36 points behind iSport, were Arden due to the strong performances of Villa and Pic, while Ricci's DPR squad finished third, a point further back. ==Teams and drivers==
