This is our sixth year taking a moment during the IndyCar offseason to revisit some careers from notable names to compete in the history of American open-wheel racing. This year provided a theme that spanned multiple decades and consideration for these great drivers in IndyCar history.
For part two, we move to a driver whose record is quite historic. Success came quick and fast for this driver as he ascended from promise to champion in a blink and he remains the youngest champion in IndyCar history. While his career took place entirely during The Split, nobody was better on his side of the fence, and he accomplished everything you could ask for. Yet, the politics muddied his place among the best all-time.
It is Sam Hornish, Jr.
Where was Hornish, Jr. coming from?
Born and rasied in Ohio, Hornish, Jr. started in karting and his family's trucking company helped support his career. When he became a national champion in karting, he moved to the U.S. F2000 championship at 16 years old. He spent a few seasons developing and trying to gain speed, finishing behind the likes of Buddy Rice, Robby McGehee and Andy Lally while also competing against Tour de France winner Greg LeMond. In 1998, Hornish, Jr. had his best U.S. F2000 season, finishing seventh in the championship but not winning a race.
In 1999, Hornish, Jr. made a move to the Atlantic Championship with a rather new team, also hailing from the state of Ohio. Michael Shank's Shank Racing gave Hornish, Jr. his next opportunity. While racing against Anthony Lazzaro, Alex Tagliani, Buddy Rice, Alex Gurney and Rocky Moran, Jr., Hornish, Jr. had a few brought spots but he had a few blemishes on his record. His most outstanding race occurred at Chicago Motor Speedway. Starting second, Hornish, Jr. went on to take victory ahead of Lazzaro, the highlight of his season as he went on to finish seventh in the championship.
At 20 years old, Hornish, Jr. considered moving to Indy Lights but saw the Indy Racing League as a better opportunity for his future, especially as his best success in the junior series came on ovals. His crew chief from U.S. F2000, Paul Murphy, was working for PDM Racing in the IRL and Hornish, Jr. contacted Murphy about an opportunity. Hornish, Jr. was hired ahead of the 2000 season.
What did IndyCar look like when Hornish, Jr. started in the series?
Broken.
Right as Hornish, Jr. was getting into car racing from karting, The Split had taken place. There were two series, more races, more teams, but quality was not at its highest in the Indy Racing League, as the IRL sought to attract American drivers believed to be overlooked talent. Nineteen American drivers competed in at least 70% of the IRL races held in 2000, and American drivers took 12 of the top 15 spots in the championship.
It was more accessible, and the IRL was more affordable compared to CART, but the equipment was inferior to what had recently been used at Indianapolis Motor Speedway and what was being used on the other side of the fence at a number of historic races.
Drivers who otherwise would not have been given a shot at the top level of American open-wheel racing and the Indianapolis 500 were now full-timers. Teams that were not on the grid a few years prior were competing full-time in the IRL.
Though it had the Indianapolis 500, the IRL was struggling for a lengthy schedule. The series was struggling to break a dozen races as it was only running ovals. The 2000 IRL season had ten scheduled races, of which nine took place. Meanwhile, CART's schedule was still growing, and reached 20 races in 2000. CART was still running on ovals while also adding more street courses and venturing to new international venues. While all nine IRL races occurred in the United States, CART ran on four continents in five countries.
How does IndyCar look now?
There is one series, and there has been since 2008.
Reunification has been a rather good period for IndyCar, though it has not been without its troubles. The series has restructured and teams received a greater of equity in the series than previously with the charter system. Each chartered entry is guaranteed a spot on the grid for every IndyCar race, and soon the IndyCar grid will be limited to only chartered entries at every event but the Indianapolis 500.
Twenty-five cars received charters, and in 2026, those 25 spots were spread over ten teams. Many teams have been holding firm since prior to The Split. Team Penske has been around for over 60 years. A.J. Foyt Racing is still around. Chip Ganassi Racing has turned into the best team in IndyCar history. Somehow, Dale Coyne Racing has lasted four decades. Rahal Letterman Lanigan Racing has been around for just over 30 years.
A few teams are relatively new. Andretti Global grew out of the opportunities created from The Split. Ed Carpenter Racing grew out of the opportunities post-reunification. Meyer Shank Racing expanded into IndyCar after over a decade in sports car racing, and it is now a two-time Indianapolis 500 winning team after its triumph this past May. Juncos Hollinger Racing came from the ladder system. McLaren returned after buying an existing team.
Eight American drivers competed full-time in 2026 with three cracking the championship top ten and four finishing outside the top fifteen in the championship. While 17 races comprised the 2026 season, only two countries were visited, both on the North American continent.
What did Hornish, Jr. do in-between?
Hornish, Jr. shot to the top at a blistering pace. Though his rookie season in 2000 was not brilliant, it was good enough to turn heads. Driving for the underfunded PDM Racing, his only top five finish was a third at Las Vegas. His only other top ten finish was in the penultimate race, a ninth at Kentucky. Doing less with more attracted interest from Panther Racing, one of the best teams in the IRL, and Hornish, Jr. took over the team’s #4 Pennzoil entry.
It didn't take long for Hornish, Jr. and Panther Racing to find success. They won the 2001 season opener at Phoenix. Then they won the second race of the season at Homestead. In 13 races, Hornish, Jr. had 11 top five finishes, and he had 12 finishes in the top six. Hornish, Jr. took the championship in his sophomore season in convincing fashion with a race to spare, making him the youngest champion in IndyCar history at 22 years old.
With Team Penske joining the IRL full-time in 2002, there was increased competition, but Hornish, Jr. did not crumble. He went first-third-first to open the season. With five total victories, including in the final two races of the season, Hornish, Jr. held off Hélio Castroneves and Penske to successfully defend his IRL title.
Though 2003 had a tougher start, Hornish, Jr. remained a contender, and he won three of the final five races, but still finished fifth in the championship. His form was great enough to attract the attention of Team Penske. Hornish, Jr was hired to replace the retiring Gil de Ferran.
Repeating his performance at Panther Racing, Hornish, Jr. won on debut with Team Penske at Homestead. However, the Toyota engine was not a match for Honda in the 2004 season, and Hornish, Jr. was seventh in the championship. Hornish, Jr. improved in 2005, winning twice and scoring nine top five finishes to take third in the championship.
With Honda taking over as the sole engine manufacturer in 2006, Hornish, Jr. and Team Penske was now on equal footing. He had a strong start to the season, and he won pole position for the Indianapolis 500. Hornish, Jr. did not spend that much of the race in the lead as Dan Wheldon controlled the race before a tire puncture forced Wheldon to make an extra pit stop. A late caution brought Hornish, Jr. into the picture for the race victory as Michael Andretti led ahead of Marco Andretti with Scott Dixon in third ahead of Hornish, Jr.
Hornish, Jr. quickly took third as Marco Andretti took the lead. Hornish, Jr. navigated the lapped car of Bryan Herta and quickly overtook Michael Andretti for second. Hornish, Jr. was gaining on Marco Andretti until backing out entering turn three on the penultimate lap. It appeared Andretti had a large enough gap to hold on for victory. On the final lap, Hornish, Jr. clawed back ground and was within touching distance exiting turn four. Using the slipstream, Hornish, Jr. was able to pull ahead and beat Andretti to the checkered flag by 0.0635 seconds for the Indianapolis 500 victory.
The Indianapolis 500 triumph lifted up Hornish, Jr.'s title hopes. He won twice early in summer but his results ebbed and flowed over the second half of the season. He went into the Chicagoland finale one point behind teammate Hélio Castroneves with four cars alive for the championship in the final race, as both Chip Ganassi Racing teammate Wheldon and Dixon had a shot.
The finale was a four-car battle between Penske and Ganassi. They were the only four cars on the lead lap in the the closing stages. Wheldon won the race with the most laps led ahead of Dixon with Hornish, Jr. in third and Castroneves in fourth. This result left Wheldon and Hornish, Jr. tied on points with Castroneves two points back. Hornish, Jr.'s four victories to Wheldon's two gave the American a third title in six seasons.
Another good year followed in 2007 with one victory, eight top five finishes and 12 top ten finishes from 17 races to put Hornish, Jr. fifth in the championship. The 2007 season was one where Hornish, Jr. split his focus as he ran nine races in NASCAR's second division, and he would earn a NASCAR Cup Series seat with Team Penske for the 2008 season.
What impression did Hornish, Jr. leave on IndyCar?
The further we get from The Split, the harder it becomes to explain Hornish, Jr.'s career and his success. He was the best the IRL produced. He was the only multi-time champion in the series before reunification. Plenty of talented drivers were around, and only Hornish, Jr. won multiple championships. Scott Dixon didn't do it. Tony Kanaan didn't do it. Hélio Castroneves didn't come in and win a title immediately, neither did Gil de Ferran.
Even Hornish, Jr.'s predecessors never grabbed a hold on the series and never let go. Neither Arie Luyendyk nor Eddie Cheever became an unstoppable force in the IRL despite their CART experience. Neither Scott Sharp nor Buddy Lazier built upon their first championships to become the star of the series, though Lazier may have been the closest to what Hornish, Jr. achieved.
When the CART teams started switching to the IRL, Hornish, Jr. was the only IRL driver that was consistently successful and a challenger. When Team Penske needed a driver, it hired Hornish, Jr. Chip Ganassi Racing didn't hire Buddy Lazier, Scott Sharp or Greg Ray when the team fully switched over. Billy Boat and Mark Dismore were not getting a call from Andretti Green Racing. All those teams trusted their talent, and history tells us rightfully so, but Hornish, Jr. was the one IRL driver that could hang with the best from CART and the only one who got a greater opportunity when the tides of the IRL began to change.
Hornish, Jr.'s career exists in a vacuum that likely will never be duplicated. Hornish, Jr. didn't run on a road or street course until the 71st start of his career. He only made 11 road/street course starts in 116 races. Hornish, Jr. never raced at Long Beach, Toronto, Road America and Laguna Seca. No one is ever going to have another career like that in IndyCar.
It is a shame Hornish, Jr. never competed post-reunification the same way it was a shame A.J. Allmendinger left for NASCAR right before reunification when Allmendinger would have been a star in IndyCar. Hornish, Jr. probably made the right business decision for himself, taking a NASCAR ride when the salaries were significantly greater than in the IRL and when his abilities may have been diminished in a changing IndyCar as oval events began to decrease while road and street races began to increase.
Hornish, Jr. spent a decade in NASCAR and found respectable speed, especially in NASCAR's second division. The immediately leap to the Cup Series brought nothing good for him, but he became a race winner and capable driver in the second division, nearly winning a championship. He hasn't raced anything in nearly nine years. His most recent NASCAR start was at Homestead on November 18, 2017 in NASCAR's second division. Today, Hornish, Jr. is only 47 years old, a little more than a year older than Scott Dixon.
It sucks we never saw Hornish, Jr. come back to IndyCar the same way we saw Juan Pablo Montoya return and A.J. Allmendinger dabble, and the same way Jacques Villeneuve came back out of nowhere to run one Indianapolis 500. Hornish, Jr. was a driver with nothing left to prove and yet so much he still could have accomplished to further his legacy. He would have received such a warm welcome if he came back just once for the Indianapolis 500, but he probably could have come back for a half-dozen years or a full decade and been a significant challenger.
It is hard to comprehend how a driver of Hornish, Jr.'s capabilities never went back to where he was spectacular. He did state after the death of Dan Wheldon he did not have the desire to run in IndyCar again, but considering the safety advancement made with the DW12 chassis over nearly the last two decades, IndyCar has been safer than ever, including over the entire period of Hornish, Jr.'s career.
If Hornish, Jr. had returned, it wasn't a question of if he could be competitive but how competitive would he have been? Even if he were to have returned in 2014 and 2015, the same time Montoya returned, I think he could have gone to Indianapolis and been a top five runner, if not a contender for the race victory.
The full-time makeup of IndyCar would have been more difficult for Hornish, Jr. to conquer again. He lacked road and street course experience, and I think he would have been mid-pack more times than not, better than the likes of Ed Carpenter and even Jimmie Johnson from his brief IndyCar career, but not on the level of Charlie Kimball or James Hinchcliffe. Hornish, Jr.'s championship position would come down to his oval form, and with only five or six oval races a season, it would be difficult for that to be a significant decider in his championship position. One bad oval race would be the difference between cracking the championship top ten and being 13th. Two bad oval races would torpedo any promising championship finish and put cracking the top fifteen in doubt.
Hornish, Jr. is going to live on his own in IndyCar history. He doesn't quite fit when compared to Dixon, Will Power, Álex Palou, Dario Franchitti or Josef Newgarden. I don't know if anyone holds Hornish, Jr. up as an equal when compared to Alex Zanardi or Gil de Ferran or Juan Pablo Montoya. How do you rate his career to Tony Kanaan or even Hélio Castroneves? Hornish, Jr. fits somewhere, but where he is placed feels like an awkward squeeze.
It is a career that could only exist in this narrow period of time, one that cannot be fully celebrated in IndyCar history because of how destructive it was. That isn't Hornish, Jr.'s fault, but it makes him harder to place him among the all-time greats. Part of Hornish, Jr.'s career is missing because of the politics of the 1990s and early 2000s, and this career does not have an equivalent to any contemporary.
The only comparable driver is Sébastien Bourdais, as Bourdais torched Champ Car while Hornish, Jr ruled the IRL, but Bourdais returned and spent a decade in IndyCar post-reunification, winning races and out-performing his equipment with multiple teams. We saw what Bourdais could do in a united IndyCar. For Hornish, Jr. it will always remain a mystery.
He was breathtaking when ovals were the only thing he could race on, but even with 19 victories in 116 starts and three championships, Hornish, Jr. does not fit easily with the other greats from recent history.
