All races were televised on theESPN family of networks. In addition, all races were broadcast live on theIMS Radio Network, andXM IndyCar Channel 145 and simulcast onXM Sports Nation.

The 2007 schedule was the twelfth season of theIRL IndyCar Series, and part of the 96th recognized season of top-levelAmerican open wheel racing. It was the final season thatIndyCar Series ran independently before the IRL merged withChamp Car in 2008. It also markedA. J. Foyt's 50th anniversary of participation inIndyCar racing.

It was also the final season that all IndyCar Series cars ran with thesequential manual gearbox shifters before all IndyCar Series cars switched tosequential semi-automatic paddle-shifters forthe following season.

2007 was also the first season that all IndyCar Series entrants utilizedDallara spec-chassis all-season long althoughPanoz chassis were still only used by part-time underfunded entrants forIndianapolis 500 event only, but without factory support fromPanoz.

• All cars will utilize a 100% fuel blend ofethanol. In the2006 season, cars utilized a 90%–10% blend ofmethanol and ethanol. From 1965 to 2005, Indy cars inUSAC,CART, and IRL used a 100% methanol blend.
• All cars will re-utilize 3.5-liter displacement engines. From 2004 to 2006, the IndyCar Series used 3.0-liter engines. From 2000 to 2003, the IndyCar Series also used 3.5-liter engines and from 1997 to 1999, the Indy Racing League was also used 4.0-liter engines. The increase in displacement is to counter the expected horsepower loss resulting from the switch to a 100% ethanol fuel blend.
• Fuel cells in the cars will be reduced from 30 gallons to 22 gallons to offset the improved mileage experienced by ethanol.^[2]
• All cars will carry a rear-mounted safety light (similar use inFormula One and other single-seater formula racing championships), to be controlled by race officials.
• On short ovals and road courses, front wings may be set at any angle between negative 5 and positive 5 degrees.
• Race day morning warm-up practice sessions have been eliminated. As a result, pre-qualifying practice sessions will be extended by 15 minutes.
• If qualifications are canceled for an event, the starting lineup will be based on entrant points. In previous seasons, top practice speeds have been used.
• Series officials will have the discretion to determine the rookie status of any driver, regardless of the number of races started in previous seasons.^[3]
• IndyCar Series teams that participate in theIndy Pro Series can earn bonus testing days for the 2007 calendar year. The bonus testing days will be awarded following participation in designated 2007 IPS events, and are shared by the team's IndyCar Series driver and IPS driver. They can be conducted at any IndyCar Series venue except Indianapolis or Mid-Ohio.

All entries utilizeHonda engines andFirestone Firehawk tires.

However, unlike at Homestead, he would not be victorious, and even lost use of his two-way radio. With about 15 laps to go, the final sequence of pit stops for fuel began, and threatened to shuffle the field. Tony Kanaan's AGR team used a late-pit strategy, which saw him take on less fuel and a shorter stop. With four laps to go, Kanaan took the lead and held off Wheldon to claim his first victory of the season. With Kanaan's win, the first three races of the season have produced three different winners representing three different teams. During practice, bothKosuke Matsuura andDanica Patrick turned in some of their best on-track performances thus far this season. Neither were factors during the race however, and Matsuura, in fact, crashed out on the first lap in front of his home country.

As the green came out,Tony Kanaan got the jump on Marco Andretti, and took the lead in turn 1. Moments later,Phil Giebler crashed, bringing the yellow out once again. Before safety crews could clear the track, heavy rain fell, and the race was red flagged after lap 113. After nearly three hours, the race resumed, with Kanaan leading. On the 156th lap, the field went back to green afterMarty Roth's crash, however, in turn four, Tony Kanaan came up on the back of Jacques Lazier, sending Lazier into the wall, and sending Kanaan's car into a spin. He blew a tire and coasted into the pits. Moments later, the field assembled for what was expected to be the final restart before the rains came.

Shortly after the restartPenske Racing teammateSam Hornish Jr.'s rear wing bent in a similar place, although mildly enough to allow him to finish the race, but he was forced to relinquish second place. These two somewhat bizarre part failures allowedAGR teammatesTony Kanaan andDario Franchitti to cruise to a 1–2 finish. On lap 89,Danica Patrick andDan Wheldon touched wheels, sending Patrick spinning. Both recovered to finish in the top ten, however, the incident led to a post-race confrontation where Patrick grabbed and pushed Wheldon, starting a feud between the two.

• Race Summary: The race start was delayed4+1⁄2 hours due to persistent rainy conditions. As a result, the US telecast was moved toESPN Classic. Once the race began, it became a war of attrition marked by two significant incidents. The first came whenHélio Castroneves andVítor Meira hooked wheels just past the start-finish line, slamming both cars hard into the outside wall. Castroneves was visibly upset with Meira after the incident and walked all the way to the infield care center, later complaining of knee pain and being diagnosed with only a bruised knee. On Lap 139, polesitterDario Franchitti and leaderDan Wheldon hooked wheels on the back-stretch, sending Franchitti sideways and later sailing upside down, landing on the cars ofScott Dixon andA. J. Foyt IV. Franchitti's car was the same one he had driven to victory in theIndy 500.^[43] The incident collected seven cars and all drivers, including Franchitti, were uninjured. A lengthy caution followed with just seven cars remaining running and on the lead-lap.Andretti Green Racing was set to capture a 1–2–3 finish untilDanica Patrick suffered a punctured right-rear tire with 13 laps to go, forcing her to pit, leaving AGR driverTony Kanaan to hold off teammateMarco Andretti for his third win of the season. The carnage resulted in career-best finishes forKosuke Matsuura (4th),Ryan Hunter-Reay (6th), and Foyt (8th) despite his car not running at the finish. There was no race at Michigan on the2008 calendar, and as of 2023, this is the last time IndyCar has raced at the track.

Franchitti would lead until the second round of pitstops, under green flag conditions. Franchitti was the first to pit, on lap 91. This allowed Kanaan andScott Dixon into the lead and second positions respectively. Both drivers would pit the following lap for their second pitstops.A. J. Foyt IV took the lead, and he would two laps, before pitting on lap 94. On the pitstops, Kanaan and Dixon had passed Franchitti, allowing them to be first and second, when everyone had made their pitstops. The race continued under green, until lap 126, when a caution was flown for debris in turn 3. Yellow-flag pitstops would occur, and a fast pitstop from the #9 crew allowed them, to lead for the restart on lap 132. Kanaan would pass Dixon the very next lap, and would hold the lead until the final round of pitstops. As Kanaan, Dixon and most of the other frontrunners pitted on lap 179, Foyt returned to the lead. As Foyt pitted on lap 181, the final yellow was flown, after an incident which began on pitlane. The AGR cars of Franchitti andDanica Patrick collided on pit entry, causing damage to Franchitti's right front wing endplate. He would need the nosecone replaced, but would not lose a lap. Meanwhile, Patrick was exiting pit road, and got on the power too early, causing her to spin. She would be bump-started by theDelphi safety crew. Next time by, still under caution, a tyre blew on the #7 car in turn 2, making her spin again, and narrowly avoided the safety crew. Foyt would lead the field to the restart on lap 190, but Kanaan was not to be denied, taking the lead for good on lap 191. Leading 131 of the 200 laps, the Brazilian won his 4th race of this season, and moved back into the championship running. Dixon finished 2nd, to further close on Franchitti's championship lead.

With time running out,Tony Kanaan was leading, and second placeBuddy Rice ran out of fuel. Third placeScott Dixon, the championship points leader going into the race, took evasive action to get by Rice, which crashed out both cars. The pileup collected points contenderDario Franchitti as well.Danica Patrick slipped by the crash and took a career-best second place, while Kanaan went on to win. Franchitti managed to continue and limped to a sixth-place finish. Tempers flared asAGR co-ownerMichael Andretti was quick to accuse Dixon of intentionally taking out Franchitti by letting off the brakes and rolling into the path of Franchitti.

• Race Summary: The final race of the season sawDario Franchitti enter with a three-point lead overScott Dixon in the championship chase.Tony Kanaan held third, the only other driver mathematically eligible for the title.Penske teammatesSam Hornish Jr. andHélio Castroneves dominated most of the race, leading a combined 146 laps.Tony Kanaan saw his championship hopes go away early in the race when a flat tire forced an unscheduled pit stop. He would eventually finish 6th in the race. Single-car crashes byMarco Andretti and laterVítor Meira were the only significant on track incidents of the day. Meira's crash on lap 136 caused damage to theSAFER barrier, and a long 15-lap caution ensued as track workers repaired the barrier. It set up a dramatic fuel strategy, as both Franchitti and Dixon decided to pit to top off their tanks, and thus gamble on stretching their fuel to the end of the race. With the laps winding down, most of the leaders ducked into the pits for a quick fuel stops. That left Dixon leading, Franchitti second, andDanica Patrick third. Patrick headed for the pits on lap 195, but spun at the entrance, bringing out the caution. Both Dixon and Franchitti attempted to conserve fuel under the yellow, and prepared for a two-lap sprint to decide the race winner, and ultimately the season championship. The green came out with two laps to go, and the two battled side by side. On the final lap, entering turn three, Dixon ran out of fuel. Franchitti slipped by to take the lead, win the race, and clinch the 2007 IndyCar Series Championship title. With Franchitti reportedly heading toNASCAR, along with possiblySam Hornish Jr., it marked what could be the final IndyCar Series race for the2006 and 2007Indianapolis 500 and IndyCar Series champions respectively.
