2006 Indy 500 Revisited: Hornish Jr's Last-Lap Pass on Marco Andretti
A Happy Hour Racing IndyCar feature. The 2026 season is on its off-week before Nashville, so we are going back to the closest frontstretch drag race the Indianapolis 500 has ever produced.
The Short Version
On May 28, 2006, Sam Hornish Jr won the Indianapolis 500 by passing 19-year-old rookie Marco Andretti about 450 feet from the line. The margin was 0.0635 seconds, roughly one car length. It was the first time in the history of the race that a driver made a pass for the lead on the final lap and won. Twenty years on, with the 2026 Indy 500 giving us another photo finish, it is still the wildest last lap the Speedway has ever seen.
How the 2006 Indy 500 Set Up a Final-Lap Duel
Hornish put his No. 6 Penske on the pole at 228.985 mph. He was the fastest car all month. Then the race got away from him. A slow first pit stop and a near spin on pit lane dropped him back, and for most of the afternoon this looked like Dan Wheldon's day. Wheldon led a race-high 148 laps in the Ganassi car and looked set to win his second 500 in a row.
A late caution changed everything. It bunched the field with under 10 laps to go and put three cars at the front that no one had penciled in for a straight fight to the flag. Two of them were named Andretti. The third was the pole sitter who had spent the day clawing back from his own mistakes. On the restart the leaders got single file and the run to the finish came down to who could time the last corner. That is where the 500 wins and loses, and everyone at the front knew it.
The Andretti Family Drama at the Front
Michael Andretti had come out of retirement for one more run at the one race that always got away from him. He led four laps late and looked like he might finally get it done in his own car. Then his son passed him. Marco Andretti, a rookie who was only 19, went by his father in Turn 1 on the lap after the restart and drove away toward a win that would have been storybook stuff for the whole family.
Michael faded to third. Marco, out front on the last lap, was one turn away from becoming the youngest Indy 500 winner ever. The whole Andretti section of the grandstand was already on its feet.
Hornish's Slingshot at the Line
Hornish was second on that last lap and stayed glued to Marco's gearbox through Turns 3 and 4. Coming off the final corner he got the run. He pulled to the inside on the frontstretch and the two cars ran side by side toward the yard of bricks. Hornish edged ahead in the final 450 feet and beat Marco to the line by 0.0635 seconds. It was the second-closest finish in Indy 500 history at the time. More than that, it was the first winning last-lap pass the race had ever produced. For Roger Penske it was a record-extending 14th Indianapolis 500 as a car owner.
Hornish kept it plain afterward. "This is the best day of my life at the Speedway," he said. He was not wrong.
2006 Indy 500 By The Numbers
Why It Still Matters in 2026
Marco Andretti never did win the 500. He came close again, sat on the pole in 2020, and led laps in other years, but that 2006 run to the last corner is the one that still stings the family. The Andretti curse at Indy is real, and this is one of the sharpest examples of it. Grandfather Mario won it once in 1969. Michael led 430 laps across his career and never won, still the most laps led by any driver who did not win the race.
Hornish went the other way. He backed up the 2006 Indy win with his third and final IndyCar Series championship that season, then left for NASCAR the next year. His name only grew in value because of one slingshot on one frontstretch. He had already won two IndyCar titles before this. The 500 was the piece missing from the resume, and he got it in the hardest way there is.
We bring it up now because the 2026 Indy 500 handed us another photo finish, and every time the 500 comes down to feet instead of seconds, this is the race fans reach for as the measuring stick. Twenty years later, the 2006 finish still sets the bar for last-lap drama at the Brickyard.
The Bottom Line
The best Indy 500 finishes are not about who led the most laps. Dan Wheldon led 148 and finished fourth. They are about who is in front when the car crosses the yard of bricks. In 2006, that was Sam Hornish Jr by 0.0635 seconds, and the race has been chasing that last lap ever since.
