It was the 14th and final round of the 2006 IRL IndyCar Series and the sixth running of the event. Dan Wheldon of Chip Ganassi Racing won the 200-lap race. Wheldon's teammate Scott Dixon finished second and Team Penske driver Sam Hornish Jr. finished third. Wheldon, Dixon, Hornish Jr., and Hélio Castroneves all entered the race with a mathematical chance of winning the Drivers' Championship. Hornish Jr. won the pole position by recording the fastest lap of qualifying, although he was immediately passed by Dixon at the beginning of the race. Wheldon took the lead on the second lap and dominated most of the race while Dixon persistently trailed him in second and battled alongside him several times. With four laps remaining, Dixon nearly collided into Wheldon and briefly backed off, allowing Hornish Jr. to take second place. Dixon passed Hornish Jr. two laps later but Wheldon again defended his position for the final two laps to take the win. There were two cautions and twenty lead changes between four drivers during the race. Wheldon's win was his second of the 2006 season and eleventh of his IndyCar Series career. The season ended with Hornish Jr. and Wheldon tied for first place in the championship standings, but the championship was awarded to Hornish Jr. by virtue of earning more wins in the season than Wheldon. Castroneves dropped to third, two points behind Hornish Jr. and Wheldon, while Dixon remained in fourth.

Though Wheldon and Dixon no longer raced alongside each other, Dixon remained in hot pursuit of Wheldon.

In the subsequent press conference, Wheldon explained that he raced with one goal in mind: leading the most laps. Despite losing the championship, he gave his congratulations to Hornish Jr., saying: "I got to give credit to Roger Penske's organization and Sam Hornish (Jr.) They've given away less points than we have." Hornish Jr., who was awarded $1,000,000 for winning the championship, thanked his pit crew for giving him quick stops and stated that he wanted to keep up with the leaders' pace and avoid making mistakes. Regarding Wheldon and Dixon's battle for the lead, Hornish Jr. said: "I didn't think I needed to stick my nose in there. I didn't want to be part of an accident."Lewandowski Dave September 10, 2006 TITLE TIEBREAKER http://www.indycar.com/news/story.php?story_id=7532 dead https://web.archive.org/web/20061017154144/http://www.indycar.com/news/story.php?story_id=7532 October 17, 2006 October 12, 2025 IndyCar Roger Penske, owner of Marlboro Team Penske, lauded Hornish Jr. for his performance: "There's no question that Sam had proven in '03 when he came to us that he was a great driver. To me, patience is the virtue that Sam has been developing. He's a smart race-car driver." Dixon expressed slight frustration with Wheldon's aggressive block on lap 196, saying: "I was trying to race side-by-side, but Dan (Wheldon) had a problem with that, so whatever." During the press conference, however, he rationalized Wheldon's block and commented: "But that's racing. Coming down to the last five laps, I probably would have done the same thing." Castroneves congratulated Hornish Jr. on winning the title and regarded him as "one the best oval drivers that I know," but was irritated at Kanaan for his racing style: "Tony was trying to race me. He stayed on the bottom. I tried to pass him, and I tried to signal to him. 'Listen, give me a break. You're not going to do anything. You just make me slow.' Every time we were side by side, it was like two, three miles per hour slower." Carpenter attributed his career-best finish (at the time) to the final caution period, which allowed him to get by many of his competitors who were bunched together during the ensuing restart. He also praised his team for their efforts: "It was a lot of fun today. We ended the season on a high note. The whole team should really be proud of themselves for what they accomplished this year.
