Ryan Hunter-Reay is the 2012 IZOD IndyCar Series champion after a drive from 22nd to fourth in the season-ending MAVTV 500 at Auto Club Speedway, as prior series points leader Will Power crashed early and despite a valiant effort to return to the track, was overtaken.

Hunter-Reay finished fourth in the race, which ended under yellow after a near identical ending to the Indianapolis 500. Ed Carpenter edged ahead of Dario Franchitti as Takuma Sato crashed through Turn 2; Sato had also lost control at the end of Indy while attempting to pass Franchitti for the win there.

With Power finishing 24th, Hunter-Reay needed to finish at least fifth to score enough points to make up the 17-point difference.

“I have no idea how we did it; it was a team effort,” Hunter-Reay said. “We were struggling. We were really in the woods. I just drove 500 miles for my life. I cannot believe we're IndyCar champions. My dream has come true.”

Power might have won the title for most gracious interview afterwards, given it was the third consecutive year he's lost the title at the last race.

“Full credit to my guys, as that gave us a couple points,” Power said of his team, able to repair the car and give him a fighting chance. “Hunter-Reay's a deserving champion and a real fighter. As far as all-around drivers go, he's up there. Three crashes on three ovals were misses in the points. Three years I've won the road course championship. It's very obvious where I lack.”

Carpenter's win is his second of his career, having also won the last oval race last year at Kentucky Speedway for Sarah Fisher Racing, and also over Franchitti. It's the first win for his Ed Carpenter Racing team and came, fittingly, in Fuzzy's 19th Hole Victory Lane.

"We were really good early, kind of struggled through the middle and the team made some adjustments and we got back in," said Carpenter, who had earlier distinguished himself by catching a lurid slide toward the wall with 30 laps remaining.

Dixon completed the podium ahead of Hunter-Reay and Helio Castroneves, who had gambled on an extra stop at the final restart to throw on a new set of tires and could potentially have gained another position or two had the race run full distance.

Early race leader JR Hildebrand's evening was ruined when he glanced the wall at Turn 4 and damaged his suspension, costing him two laps in the pits while his car was repaired.

Rubens Barrichello was also in the frame for a good result, running as high as third before his engine went up in flames just before the halfway mark.

Graham Rahal in sixth was the last car on the lead lap. Sato ended seventh ahead of Marco Andretti, Katherine Legge (first top-10 finish of the season) and Charlie Kimball.
