The Addax team has handed Jake Rosenzweig a full-time seat in the GP2 Series for the coming season.

The American driver raced for the team at the Monza and Singapore rounds at the end of the 2012 season, replacing Josef Kral after the Czech’s victory at Spa. Rosenzweig qualified 24th out of 26 for both events and had a best finish of 15th. He then took part in both post-season tests at Barcelona and Jerez for the Spanish squad.

The 23-year-old contested his third season of the Formula Renault 3.5 Series in 2012, finishing 21st in the standings with one points finish as teammate to title contender to Sam Bird at the ISR team. He was 15th in 2011 with Mofaz and 19th in 2010 with Carlin.

“I am excited to be joining Addax for the 2013 GP2 season and wish to thank all involved for making this possible,” said Rosenzweig, who joins Indonesian driver Rio Haryanto in Addax’s lineup for 2013.

“Having raced in the final two rounds of the 2012 championship with Addax, I know what an opportunity this represents to be working with them again. The race calendar has some great circuits and I am looking forward to hitting the ground running. I will do my best to score as many points as possible over the course of the season.”

Addax owner and team principal Alejandro Agag added: “I’d like to welcome Jake Rosenzweig although he is almost part of the family after having competed in four races and done four complete tests with us.

“We are keen to count on his services because he has shown that he is willing to work very hard to improve in each and every race and training session. The whole team and everybody involved is delighted with his professional attitude. I’m sure that together we can form a good tandem of team-driver competitive enough to get closer to the leading drivers of every race.”

Agag’s outfit won the teams’ title in 2011 when its drivers were Charles Pic and Giedo van der Garde. They had previously come second in 2009 and 2010 with drivers including Vitaly Petrov, Romain Grosjean and Sergio Perez.

For 2012 they signed Johnny Cecotto Jr and Kral but struggled considerably compared to previous seasons, as they finished down in eighth in the championship.
