Andretti Autosport
With CART facing financial trouble at season's end, Michael Andretti took the team, then called Andretti Green Racing and now Andretti Autosport, full-time to the IndyCar Series for 2003. Andretti Autosport has since scored four Indianapolis 500 wins -- 2005, 2007, 2014, and 2017. Andretti also is a partner in Bryan Herta Autosport in the 2016 race that team won.
