Former Porsche Supercup frontrunner Kuba Giermaziak will complete Greaves Motorsport's line-up for this year's Le Mans 24 Hours.
The Pole joins Memo Rojas and Julien Canal in the team's LMP2 class Ligier JS P2-Nissan, with the trio also contesting the full European Le Mans schedule.
Giermaziak, 25, made his La Sarthe debut last year in a GTE-Am class Ferrari 458 run by the JMW Motorsport squad, partnering Michael Avenatti and Abdulaziz al Faisal.
Prior to that, he finished as runner-up to Porsche factory driver Earl Bamber in the 2014 edition of the Formula 1-supporting Porsche Supercup series.
"It will be absolutely amazing to drive for Greaves Motorsport in the European Le Mans Series and 24 Hours of Le Mans this season in the LMP2 class," said Giermaziak. "It’s a dream come true for me, as driving prototypes was something I wanted to do since I was a little kid.
"We have everything we need to fight for the championship, with a great team behind us, and Memo and Julien to share the cockpit with.
"They are both fantastic drivers and I’m sure that we can all learn from each other.”
Greaves will have just a sole entry into this year's Le Mans 24 Hours, its second entry - the first on the reserve list - having been officially withdrawn last month.
