What a year it's been for Ryan Hunter-Reay! After a dismal 2011 (remember Andretti Autosport having to buy an Indy 500 race seat for Hunter-Reay from AJ Foyt?) he started well enough with two podiums in the first run of four road races, but after Texas he was in just seventh place in the championship. And then it all changed: back-to-back wins at Milwaukee, Iowa and Toronto suddenly vaulted him to the top ahead of Will Power, and after that it was a head-to-head duel between the pair that went all the way to the thrilling season finale at Fontana. Even after Power crashed out, Hunter-Reay had to keep his head and finish in a sufficiently high position to grab the title - which he did, becoming the first American IndyCar champion since Sam Hornish Jr. in 2006.
