Greaves Motorsport has confirmed Gary Hirsch, Jon Lancaster and Bjorn Wirdheim as its drivers in the European Le Mans Series and the 24 Hours of Le Mans.
The trio tested together at Circuit Paul Ricard last month in the Gibson-Nissan LMP2 car.
Twenty-eight year-old Swiss driver Hirsch was the ELMS LMPC champion in 2013 before claiming a n overall win with the New Blood by Morand team at last year's 4 Hours of Paul Ricard.
Jon Lancaster from Leeds in the UK turns his attentions to endurance racing after largely competing in GP2 over the last couple of seasons. Lancaster scored a podium finish in the 6 Hours of Bahrain in 2013 on his endurance racing debut.
Wirdheim has had an extensive career in single seaters, including spells as a test driver for Formula 1 teams Jordan, BAR and Jaguar, as well winning the International Formula 3000 title in 2003.
Since then he has competed successfully in Japan. He too raced with Greaves Motorsport in 2013 joining Lancaster on the podium in the final race at Bahrain.
"The driver line-up of Gary, Jon and Bjorn is very strong, all are fast and experienced, which is just the mix required for success in endurance racing as we have proved in the past," said team boss Tim Greaves.
"Their input and the input of our racing partners, Kairos Technologies, Gibson, Nissan and Dunlop will give us a platform to race at the highest levels in what will surely prove to be a very competitive LM P2 category at Le Mans and in the European Le Mans Series. We are cautiously optimistic about the 2015 season."
Motorsport.com understands that the team could also enter a second Gibson-Nissan LMP2 car in the ELMS later in the season.
