Danish race winner replaces F1-bound Felipe Nasr to join Julian Leal in 2015.
Marco Sorensen has completed Carlin’s 2015 GP2 line-up, joining the already-announced Julian Leal at the British squad.
The Lotus F1 Team reserve and development driver is a race winner in the series from the Sochi sprint race in 2014 with MP Motorsport. He brings backing from Saxo Bank.
Sorensen only completed a part season – joining the series at Silverstone but still managing 10 top-10 finishes. Previous to 2014, Sorensen had race-winning experience in Formula Renault 3.5, German F3 and the F3 Euro Series.
“I am hugely excited to be joining Carlin for the 2015 season in GP2,” said Sorensen. “The team has a great reputation and I feel I have some unfinished business in the series. Together I expect us to be aiming for top results.
“My thanks go out to Gravity Sports Management and Saxo Bank, without whose support this attack on the GP2 championship would not be possible. We’re focused on working hard now to prepare for the season ahead and the first tests in Abu Dhabi.”
Team owner Trevor Carlin said: “We are extremely happy to complete our GP2 team with the signing of Marco. He is undoubtedly a very quick driver and in the right environment I have no doubt that we will see him flourish.
“In addition, we know him to be a great driver to work with and together with Julian [Leal] we expect to have a very productive working environment in which to strive for further success in GP2.
“We are delighted that Marco’s sponsors and the Lotus F1 Team have shown the belief in us to take Marco to the next level of his career.”
The GP2 teams will be on track for the first official test in Abu Dhabi from March 9-11.
