The iconic endurance race has long been a goal for the MotoGP legend who has completed his first season on four wheels.
Rossi raced for the WRT team in the GT World Challenge Europe, driving an Audi, and produced steadily improving results as the year progressed.
Rossi has confirmed he will stay with the WRT team for 2023, but the team is switching from Audi to BMW, and the Italian has already tested the new M4 GT3 car.
BMW has separately confirmed that it will enter the Hypercar category of the 2024 24 Hours of Le Mans.
That means a good season at the wheel of a BMW could earn Rossi a place with the manufacturer in the legendary endurance race the following year.
“This year I raced with the Audi but next year I will be in the BMW,” he told Sky.
“I’m going to become a works driver and I’m very happy about it. I have already tested the car, I will stay with the same team as last season. We’re just changing cars.
“WRT was with Audi for 15 years but BMW was chosen for 2023. I tested it on Monday after the last race in Barcelona. It is beautiful, very modern, twin-turbo, bigger than the Audi. It seems more easy to drive.
Rossi said recently about the 24 Hours of Le Mans, his long-time dream: “I would love to try it and once again we hope to organize a test.
“Then, however, it will be necessary to understand how fast I will be to become a Hypercar class driver. It will be a difficult challenge.
Rossi, now 43, is a seven-time MotoGP champion whose protege Francesco Bagnaia became the 2022 champion.
