In the modern sense of the word, Roger Penske has 'owned' the Indianapolis Motor Speedway for quite some time. His team's 18 Indianapolis 500 wins are one obvious illustration of that, since nearest rival car owners Michael Andretti and Lou Moore are on five apiece (won between 2005 and '17, and '38 and '49 respectively), and Chip Ganassi is on four ('00-12).
No less significant is how rarely Penske cars are off the pace at Indy: sure, the occasional bad pitstop or driver misjudgment will harm the result, but in terms of pace, 'The Captain's' armada is a perennial contender.
That's no surprise. It's an open secret within Penske that the boss puts higher stock in conquering the Brickyard than winning the IndyCar championship, so much of the squad's off-season car development goes into superspeedway improvements. And that will remain the case even now that Pocono Raceway's deletion from the IndyCar calendar leaves IMS as the series' only oval over 1.5 miles in length.
