Jann Mardenborough has been confirmed as the third and final driver for Carlin ahead of the 2015 GP3 series as he tests with the team in Estroil this week.

Mardenborough will combine his GP3 campaign with his commitments in the FIA World Endurance Championship with Nissan NISMO in the LMP1 category. The Japanese manufacturer recently announced it will miss the opening two WEC rounds after suffering development problems with its new GT-R LM NISMO car but expect to race in Le Mans in June.

The Nissan driver finished ninth in GP3 last year racing for Arden International, notching up a maiden victory in the Sprint race at Hockenheim.

The Welsh driver shot to fame after being selected as one of the young stars from 90,000 hopefuls during the 2011 Nissan PlayStation GT Academy Europe competition.

At just 23-years-old he has already competed in the British GT championship, Blancpain Endurance Series and the Le Mans 24 Hours race, where he finished third in the LMP2 class in 2013 with Greaves Motorsport.

The Welshman called the news surprising despite having already declared he had ambitions of racing in GP3 and WEC this season.

"I was thinking at the start of the year that it would be amazing to do both LMP1 and GP3 so I'm very happy and surprised that this has happened," Mardenborough said.

"The championships are relevant to each other - all racing is - but they do require different skills. GP3 is short sprints so the racing is very aggressive from lap one until the flag, whereas in LM P1 the races are between six and 24 hours long so the ability to quickly change strategy is required along with the obvious need for physical and mental endurance."

The Cardiff-born driver makes a return to Carlin after racing with the team in the British F3 series two years ago. The British team secured the drivers' and teams' GP3 titles last season and have set themselves to goal of retaining them this year.

"It's great to go back to Carlin for GP3," he continued. "I made my single-seater debut with them and they are a very professional outfit. I want to be a winner so I'm going to be using what I learnt last year to improve my performance and to challenge for podiums and lots of points."

Trevor Carlin says he is delighted to secure Mardenborough's services and sees the driver as a genuine title contender.

"Jann completes an extremely strong line-up for us," Carlin said. "Having worked with him in F3 and seeing him continue to develop in GP3, I have no doubt that Jann will be a potential race winner from the start.

"It's fantastic to see the path his career has taken; from a gamer at home to a competitive GP3 racer on track and we're thankful to the GT Academy and Nissan for entrusting us with this next step in Jann's single seater career."

Mardenborough joins Antonio Fuoco and Mitch Gilbert at Carlin for the upcoming GP3 series.
