From its modest beginnings behind a Philadelphia-area watchmaker's shop some 40 years ago, the Penske Racing Team, more than any other organization, has influenced the development, growth and direction of auto racing in the United States both as a sport and as a business. Led by former race driver turned 'Fortune 500' business mogul Roger Penske, this team has won more than 250 major auto races around the world and captured 19 national championships, including 12 Indy-Car titles.
