Tom Dillmann has completed iSport's lineup for the non-championship GP2 races at Yas Marina next weekend.
The 22-year-old Frenchman tested for the squad at Barcelona last month and will join Marcus Ericsson, who announced he will stay with the team for the 2012 season on Tuesday.
"Tom has shown great pace and capacity to learn in the recent tests and has demonstrated that he is ready to move up from the GP3 Series," said team principal Paul Jackson. "As a GP3 graduate, he is eligible for the special prize fund and we will be hoping to help him secure a share of that."
Although he has never raced a GP2 car before, Dillmann does have a strong record in junior open-wheel racing, having won races in Formula Renault and taken the German F3 title in 2010. This year he was a podium finisher in both the F3 Euro Series and in GP3, despite not taking part in a full campaign in either series.
