Le Mans 24 Hours LMP2 winner Charles Milesi will drive the GR010 Hybrid LMH at the Bahrain Rookie Test with Laurents Horr set to drive a GTE.
The World Endurance Championship rookie debuted with Team WRT, who were also making their debut, in the LMP2 category.
The 20-year-old claimed his first pole position at Monza for the 6-hour race.
Alongside teammates Robin Frijns and Ferdinand Habsburg, they secured second in LMP2 before claiming a victory at the following round – the 24 Hours of Le Mans – in his second attendance.
The young driver test commences a day after the 8 Hours of Bahrain finale and will see him debut in Toyota’s Le Mans Hypercar which took the overall Le Mans victory over a month ago.
The Frenchman said: “I’m really happy with this opportunity, being able to drive a Hypercar and also the one which has won Le Mans this year – it’s unbelievable.
“I would like to thank everybody, first WRT because we have had an incredible year so far and also the ACO, the WEC and Toyota for this amazing opportunity.”
He sits one point behind the #28 JOTA LMP2 leaders ahead of the Bahrain double-header which will close Season 9.
Joining him will be Laurents Horr, a two-time Michelin Le Mans Cup champion in 2019 and 2020 and current European Le Mans Series competitor for DKR Engineering.
The 24-year-old will be driving either the GTE-Pro Ferrari 488 (Evo), or the Porsche 911 RSR-19, at the test.
It will be the first time the German will work with a factory team.
Each of the two drivers will be awarded a minimum of 30 laps during the test day (running from 10am to midday and then from 1pm to 4pm, local time).
These five hours of track time will be available for other WEC teams to test other potential drivers ahead of the 2022 season.
A full entry list of the rookie test will be unveiled in due course before the first leg of the double-header on 30 October.
