The Month launches on August 31 and will preview the upcoming four weeks' top entertainment events and releases, including film trailers and album samples, featured in the Culture supplement.
The CD will also provide links to websites where readers can buy tickets or products, such as albums and computer games, featured on the CD.
Jonathan Wignall, national advertising manager for Renault UK, said the sponsorship would help it reach its target market.
"It is always exciting to be involved with a media first. We believe it is very dynamic way of reaching our target audience," he said.
The Month is edited by David Johnson, who has been at the Sunday Times for seven years and has edited Doors, the paper's internet and technology section. Before that, he worked for The Face.
The CD-rom will come in a specially designed CD wallet within The Sunday Times Magazine polybag on the last Sunday of every month.
It will include film releases, CD and computer games reviews/samples and comprehensive listings.
Dino Ioannou, account director at Carat, said: "The Month is brave, exciting and innovative. Renault is always hungry for creative ideas that can enhance its marque values."
The deal was negotiated by Carat Press Communications associate director Danny Lloyd.
