For 2011, Keselowski moved over to Penske's long time flagship car, the No. 2 Miller Lite-sponsored Dodge. The switch with Kurt Busch, who had driven the car since 2006, occurred due to a sponsorship change and consolidation of operations at the team. Royal Dutch Shell, who had most recently sponsored Kevin Harvick's No. 29 Chevrolet for Richard Childress Racing, signed on to sponsor Penske's second car, which Keselowski had been driving. At the insistence of Shell, the more experienced Busch was moved to the renumbered No. 22 Dodge and his crew went with him. Keselowski, meanwhile, had his crew follow him to the No. 2 and the team's third unit, the No. 77 which had been driven by Sam Hornish Jr., was dissolved (its sponsor, Mobil 1, had left the team) and its operations merged with Keselowski's team.
