Bjorn Wirdheim and Jon Lancaster will return to the Greaves Motorsport LMP2 squad to contest the full European Le Mans Series and the Le Mans 24 Hours this season.

Wirdheim and Lancaster, who raced together with the team in one World Endurance Championship round in 2013, will share its solo Gibson-Nissan 015S (nee Zytek) with Swiss driver Gary Hirsch. The duo took part in last month’s official ELMS test at Paul Ricard and have been signed up after confirmation of the team’s partnership deal with data encryption company Kairos Technolologies.

“Bjorn and Jon helped us out in the past and we have been able to repay them because we now have the opportunity to chose our drivers,” team owner Tim Greaves said. “We have one of the best line-ups in the ELMS on paper, and we are very pleased about that.”

Greaves revealed that the team would test some drivers imminently with a view to fielding a second car in the final rounds of the ELMS after Le Mans in June.

Wirdheim made it to the fringes of F1 in 2004, the year after being crowned International F3000 champion. He ran during Friday practice in all 18 grand prix weekends in his capacity as Jaguar third driver.
