The multiyear deals with the brewer's two biggest brands was announced Thursday.
The deal extends the sponsorship of Coors Light as the official beer of NASCAR. That program began in 2008 after Coors Light ended its sponsorship of the No. 40 car.
Miller Lite also extended its relationship as primary sponsor of Brad Keselowski's No. 2 car with Penske Racing. Miller Lite has partnered with Penske and the No. 2 car since 1991.
