Supercars aces Craig Lowndes and Shane van Gisbergen will drive a factory-backed McLaren at the Bathurst 12 Hour GT race next year.
Reigning winner Lowndes will switch from the 2017 race-winning Maranello Motorsport squad to the factory-backed YNA Autosports McLaren outfit.
He will be joined by former McLaren works driver van Gisbergen and current works driver Come Ledogar, who combined to win the 2016 Blancpain Endurance title.
"The Bathurst 12 Hour is one of my absolute favourite events, so I am delighted to have the chance to defend my win in 2017 but in a McLaren for the first time," said Lowndes.
"McLaren is an iconic name in motor racing and the 650S is a serious bit of kit, so I am really excited about the opportunity to race it at Bathurst.
"I can't wait."
Van Gisbergen returns to the manufacturer that he won the 2016 Bathurst 12 Hour with, after driving an STM Mercedes at Mount Panorama in February 2017.
"I'm excited to be back in a McLaren for the Bathurst 12 Hour," added van Gisbergen.
"I think we've got a strong driver line up, a strong team and a strong car, so I'm looking forward to the event."
Ledogar has not won the race, but did finish fifth at Mount Panorama earlier this year in a Tekno McLaren alongside Alvaro Parente and Rob Bell.
YNA is expected to field two McLarens, with the second driver line-up yet to be revealed.
