Contested over 200 laps, it was the 10th round of the 2003 IRL IndyCar Series and the second running of the event. Alex Barron of Mo Nunn Racing won the race starting from the sixth position. Panther Racing driver Sam Hornish Jr. finished second and Tomas Scheckter came in third for Chip Ganassi Racing. Scheckter won the pole position, the fifth of his career and second consecutive at Michigan, by posting the fastest lap of qualifications. Hornish Jr. led 126 laps—more than any other competitor—as his performance was boosted by a new variant of the Chevrolet Indy V8 engine, which sparked controversy among some drivers. Along with Hornish Jr., the first position was hotly contested throughout the race by Scheckter, Scott Dixon, and Barron, the latter of whom spun into Scheckter on the 164th lap but avoided causing any damage to his car. The last green-flag stint, beginning on lap 169, saw Hornish Jr. and Barron battle for the win, with Hornish Jr. utilizing the inside line to his advantage. Barron finally nosed ahead of Hornish Jr. on the final lap to take the victory by 0.0121 seconds, the fourth-closest finish in IndyCar Series history (at the time). Barron, substituting for the injured Felipe Giaffone, earned his and Mo Nunn Racing's second and final win in the IndyCar Series. With six races left in the season, Tony Kanaan, who led the Drivers' Championship prior to the race, fell to second behind fifth-place finisher Dixon as Gil de Ferran was relegated from second to third. Toyota continued holding their lead in the Manufacturers' Championship over Honda and Chevrolet.

Kanaan and Unser Jr. each led a lap until they came into pit road. With Barron entering pit road on lap 114, Hornish Jr. reclaimed the lead and was 4.7 seconds ahead of Scheckter. As Scheckter was relegated to fourth place by Barron and Unser Jr., Hornish Jr. continued extending his lead throughout the 31 succeeding laps. He held a 7.8-second advantage until the third caution flag was issued on lap 145 for debris spotted on the track. The leaders again made pit stops during the caution. Hornish Jr. nearly collided into the rear of Dixon's car exiting pit road, dropping him to sixth. left|thumb|234x234px|Alex Barron (pictured in 2006) earned his second and final IndyCar Series win by 0.0121 seconds.

He moved back into third on lap 153, by which point Takagi improved from seventh to second, 0.05 seconds behind his Mo Nunn Racing teammate Barron. On lap 155, Hornish Jr. pulled ahead of Takagi on the front stretch to take second.

Seven laps later, Hornish Jr. finally pulled ahead of Barron in turn four as they and Scheckter drove three-abreast for the lead. Barron then drifted up into Scheckter and they both made contact, sending Barron spinning into the front stretch grass. Barron managed to regain control of his car without sustaining any damage.July 27, 2003 Michigan: Barron wins three-way thriller https://www.autosport.com/indycar/news/michigan-barron-wins-three-way-thriller-5024695/5024695/ live https://web.archive.org/web/20220817171638/https://www.autosport.com/indycar/news/michigan-barron-wins-three-way-thriller-5024695/5024695/ August 17, 2022 December 9, 2025 Autosport The fourth (and final) caution was prompted, and most of the leaders, including Hornish Jr., made their final pit stops for fuel. Unser Jr. was the lone driver not to make a stop and assumed the lead for the restart on the 169th lap, though Hornish Jr. accelerated quicker than him and overtook him for the lead. On lap 170, Unser Jr. fell to ninth place as Scheckter, Hornish Jr., and Takagi ran alongside each other, with Scheckter leading the lap. Hornish Jr. nosed ahead of Scheckter to take the lead for the next two laps. By utilizing Hornish Jr.'s slipstream, Barron gained enough momentum to move into second place, though he failed to take the lead from Scheckter. Scheckter, Hornish Jr., and Barron drove three-wide for the lead on lap 175. Scheckter continued to hold his lead until the 177th and 178th laps, when Hornish Jr. charged ahead by less than a tenth of a second. Scheckter led once more on lap 179, but was again overtaken by Hornish Jr. on the next lap. Hornish Jr. and Barron began pulling away from the rest of the field and raced alongside each other for the lead, with Hornish Jr. leading laps 180–189 while holding onto a 0.02-second advantage. Meanwhile, Sharp moved up to third on the 188th lap. On lap 190, Barron eked ahead of Hornish Jr. by seven thousandths of a second, but lost the lead to Hornish Jr. the next lap. Scheckter overtook Sharp for third place by lap 193 and remained steadily behind Hornish Jr. and Barron, the latter of whom briefly assumed the lead yet again on laps 194 and 195. On the 196th lap, Scheckter raced alongside Barron for the second position, allowing Hornish Jr. to get by Barron for the lead and briefly lengthen his advantage over him. Barron attempted to gain a draft and execute a slingshot pass several times over the next three laps, but failed and drove behind Hornish Jr. On the final lap, Barron steered up to the outside line in turn three as Hornish Jr. raced on the inside. Barron was able to garner enough speed to slip past Hornish Jr. and earn his second IndyCar Series win by 0.0121 seconds over Hornish Jr., marking the fourth-closest finish in series history thus far and the closest finish in Michigan International Speedway's history.Barron Wins Firestone Indy 400 http://dbserver.iscmotorsports.com/MISpeedway/headlines.cfm?HeadlineStoryID=11910&TemplateDisplayMode=2&TeaserMode=False&PreviewLevel=0&EstablishmentType=T&Establishment_ID=6& dead https://web.archive.org/web/20030803124125/http://dbserver.iscmotorsports.com/MISpeedway/headlines.cfm?HeadlineStoryID=11910&TemplateDisplayMode=2&TeaserMode=False&PreviewLevel=0&EstablishmentType=T&Establishment_ID=6& August 3, 2003 December 9, 2025 Michigan International Speedway Scheckter came in third, ahead of Sharp in fourth and Dixon in fifth.

In my career since I moved up, I've done a lot of development programs. You know, when I go racing, I want to race competitively with a competitive car.

Kanaan wasn't sure what caused his mechanical issue which kept him out of contention for the win: "We're not sure what happened. All of a sudden we lost a lot of speed. It's a shame. But, hey, Honda did a great job of giving me a fast engine, the whole Team 7-Eleven gave me great pit stops, and we had a great race up until then. Days like this will happen.
