The Caracas, Venezuela-born driver has been in GP2 since replacing Andreas Zuber at FMS International in the 2008-9 GP2 Asia series. He was only given one-off weekend outings in the subsequent 2009 GP2 and 2009-10 GP2 Asia series, running for Trident, Arden International and Barwa Addax before finally getting a full season of GP2 starts with Arden last year. He scored 4pts during the season - all of them at the Belgium weekend at the end of August - and ended up in 24th position in the championship.
"I'm really satisfied to have with us a driver like Rodolfo, who proved, during the latest winter test he entered with our team, to have huge determination, and a strong will to emerge at the top," said team founder Maurizio Salvadori. "We'll be able to count on a really motivated racer with an one-year experience in the championship."
Gonzalez will be joined at Trident by Monaco-based driver Stefano Coletti, whose signing was announced by Trident last October. Coletti appeared in three races in GP2 in 2009 for Durango and last year competed in both GP3 and the Formula Renault 3.5 Series.
The first GP2 Asia race is on February 11, while GP2 is scheduled to begin on May 7 as one of the support events at the Turkish F1 Grand Prix.
