Austrian set for third full season in Formula One feeder series.
Trident has signed Rene Binder to partner Ferrari Driver Academy star Raffaele Marciello in its GP2 Series line-up this year.
The 23-year-old Austrian finished 25th in the points in 2014 with Arden International, his second full season in the championship. He previously raced for Venezuela GP Lazarus, starting partway through 2012.
“I'm delighted to be part of the Trident GP2 team together with Raffaele Marciello, who is one of the world's quickest young drivers,” said Binder.
“I merged with the team straight away and that was clearly demonstrated by the laptimes logged during the year-end test at Yas Marina. We have been off to a flying start together, but we are also aware of the hard challenges we will be facing.
Anyway, I'm honoured for having been chosen by the team and I will try to reward their trust as hard as I can."
Trident scored two race victories last year with Johnny Cecotto Jr.
Team principal Maurizio Salvadori added: "I'm very satisfied with the team we have been able to put together for this season. Our goal will be to stay at the front of the field and both our drivers have what it takes to help achieve great results.
“We met Rene at the end of the 2014 season and we appreciated the efficiency of his driving style, which is clean and aggressive. The laptimes set [in post-season testing at Yas Marina] were extremely interesting."
