The six-time Olympic cycling champion has joined the Japanese manufacturer's Academy outfit Team RJN and will be partnered in its NISMO GT-R GT3 predominantly by Alex Buncombe.
Other members of the Academy will fill in for any races Buncombe misses.
Hoy, 38, only made his car racing debut last season in the Radical SR1 Cup after retiring from a glittering cycling career that also took in 11 world championship titles, and has driven a variety of Nissan GT cars in preparation for the step up.
"It's a very exciting project but quite scary too," he said. "It's a big challenge but I'm really looking forward to it and can't wait to get stuck in.
"It's quite intimidating [but] I want to do my best and do these guys justice.
"It might sound ridiculous right now but my ambition in motorsport is to compete at Le Mans.
"Who knows if it's even remotely possible but that's my dream. I'm in the right place to do it."
