Addax signed 2008 GP2 Asia Series season champion Romain Grosjean and existing Campos driver Vitaly Petrov for its 2009 campaign.

For the 2010 season, Petrov graduated to Formula One, also with Renault, and Valsecchi moved to the iSport International team, so Addax signed second-year drivers Giedo van der Garde and Sergio Pérez.

Although he did not win a race, Van der Garde scored a consistent string of podium finishes in the first half of the season which established him in second place in the championship behind runaway leader Grosjean, now back in the series and driving for DAMS.

However, he slipped back to fifth in the standings after a poor end to the season and was pipped by Pic, who impressed with three pole positions and two race victories.

Despite finishing fourth and fifth in the drivers' standings, Addax won its second teams' championship by virtue of the fact that the top three—Grosjean, Luca Filippi and Jules Bianchi—had all been partnered with teammates who scored much fewer points by comparison.

Having previously scored a meagre four points over more than two years of GP2, Cecotto made a breakthrough with Addax, winning the feature races at Monaco (from pole position) and Hockenheim.

For the final GP2 Asia season in 2011, Addax reverted to running its main series drivers (Van der Garde and Pic) throughout.

On this occasion, Smith was the best of the five, scoring two podium finishes and setting a fastest lap to take 12th overall; Chaves was 19th and Storey 37th; Dillman and Ghirelli were 14th and 25th having also competed for other teams.
