Last week, after an extended period of research, we covered who led the IndyCar championship after the most number of races. We found an answer. After the most recent in Long Beach, Álex Palou has now led the championship after 56 races in his career. Not bad as he inches closer to the all-time record.
Going over the 107 drivers to lead the championship at least once since the end of World War II, we covered every driver who led the championship for at least ten races. That was 42 drivers. In this part, we will look at the remaining drivers.
T-43. Bill Holland - 9
T-43. Pat Flaherty - 9
T-43. Marcus Ericsson - 9
Holland led the championship for eight races in 1947. However, he failed to score points in three of four races from the second Milwaukee race through Pikes Peak, and this allowed Ted Horn to take the championship lead with two races remaining. Horn won the finale to clinch the title. Holland would lead the championship after one other race, Milwaukee, the third race in the 1949 championship.
Pat Flaherty won the 1956 Indianapolis 500 and led the championship for the first nine races, but Flaherty was injured in the sixth round of the season at Lakewood Speedway in Atlanta. Jimmy Bryan chipped away, took the championship lead after race #10 , and went on to claim the title. Flaherty was second in the championship.
Yeah, Marcus Ericsson has led the championship after nine races in his career. Ericsson first led the championship after he won the 2022 Indianapolis 500. He then lost the championship lead for one race after Belle Isle and then proceeded to take it back at Road America. He led the championship through the Iowa doubleheader before Will Power took the championship lead for good after the second race on the Indianapolis Motor Speedway road course.
Ericsson would lead after winning the 2023 St. Petersburg season opener and then regained the lead for two more races until Álex Palou won the Grand Prix of Indianapolis and never looked back.
T-46. Bill Vukovich - 8
T-46. Jim McElreath - 8
T-46. Tony Stewart - 8
Vukovich led after the first five races in 1953, but he only started one of those races, the Indianapolis 500, which he won. He led after the first three races in 1954 as well, but he started Milwaukee after winning the Indianapolis 500, only to finish last at Milwaukee due to a steering issue.
McElreath won the 1966 season opener in Phoenix and led the championship after eight of the first nine races. He never led the championship again
Stewart led for eight consecutive races. The final three races in the 1996-97 Indy Racing League season and the first five races of 1998.
T-49. Jim Rathmann - 7
T-49. Danny Sullivan - 7
Rathmann led for five races in 1957 and then after the first two races in 1959, the year he won the Indianapolis 500.
All seven races Sullivan led in his career were in his 1988 championship season, a year he closed leading the final five races.
T-51. George Amick - 6
T-51. Buddy Lazier - 6
T-51. Scott Sharp - 6
T-51. Ryan Briscoe - 6
Amick took the championship lead after the fifth race in the 1958 season and led for six races despite never winning a race. He lost the championship lead with three races remaining to Tony Bettenhausen, who ended up winning the championship despite not winning a race.
All six of Lazier's races led were in his 2000 championship season. He led the final three to win the title.
Sharp's first time leading the championship was when he finished tied for the championship lead after the 1996 Indianapolis 500 with Buzz Calkins, the final race of the three-race 1996 Indy Racing League season. The IRL declared both driver champions. Sharp then won the 1996-97 season opener from Loudon, his first career victory, keeping him in the championship lead. He would lead after three races in 1998, and he would lead again after his victory in the 2003 Motegi IRL race, the third race of that season.
Briscoe led the championship six times in 2009. He had a hand on the championship in the penultimate race before a pit lane incident cost him the championship lead and he finished third behind Dario Franchitti and Scott Dixon.
T-55. George Robson - 5
T-55. Walt Faulkner - 5
T-55. Scott Goodyear - 5
T-55. Greg Moore - 5
T-55. Bruno Junqueira - 5
T-55. Ryan Hunter-Reay - 5
Robson won the first race post-World War II, the 1946 Indianapolis 500. He lost his life at Lakewood Speedway, but he still kept the championship lead until Ted Horn overtook him in the finale.
Faulkner led for five races in 1950, and he led into the Darlington season finale. We will finish this story in a little bit.
Goodyear led after five races in the 1999 IRL season, but he ended that season with six finishes outside the top ten including five consecutive finishes outside the top fifteen and three consecutive finishes outside the top twenty. This dropped Goodyear to ninth in the final championship standings.
Moore led after two races in 1998, and he won the 1999 season opener from Homestead, allowing him to lead the championship for the first three races.
Junqueira led once in 2003, three times in 2004 and once in 2005. He led the 2005 championship after winning the second race of the Champ Car season at Monterrey. It was his final start of the year as he would injury his back in the Indianapolis 500 a week later as Newman-Haas Racing returned to the Speedway for the first time in a decade. What could have been if Junqueira had remained healthy?
Hunter-Reay led the championship three times in 2012. The first time was after he concluded a three-race winning streak in Toronto and then he led the race after that in Edmonton. Then he took the championship lead in the finale after Will Power had an accident early in the race. He would not lead the championship again until he won the 2014 Indianapolis 500, and he led after the following race as well.
T-61. Mauri Rose - 4
T-61. Scott Pruett - 4
T-61. Mike Groff - 4
T-61. Patricio O'Ward - 4
The only time Rose led the championship was after his Indianapolis 500 victories in 1947 and 1948. In 1947, it lasted for one race. In 1948, it dragged on for three races.
Pruett led after two races in 1995, Long Beach and Nazareth. He actually led after the second race in 1996, the only driver to lead that year other than Jimmy Vasser. Pruett retook the championship lead after the third race in 1997 when he opened with finishes of fifth, first and third.
Mike Groff led the championship! In the 1996-97 IRL season, Groff was fourth and third in the first two races. It gave him the championship lead. He was then second at Orlando over four months later, keeping him in first. Then he was sixth at Phoenix and remained first in the championship. Twelfth in the Indianapolis 500 kept Groff five points ahead of the field in the championship. One week later at Texas, he would break a leg in a practice accident and he only started one other race that season. He made three more starts in 1998 and that would be it for his IndyCar career.
O'Ward led twice in 2021, after the second race in 2023 and he led after the 2024 season opener after Josef Newgarden and Scott McLaughlin were disqualified for a push-to-pass infraction. However, IndyCar did not find that infraction with the Team Penske cars until after the second race at Long Beach. O'Ward was never officially published as a championship leader for the St. Petersburg result, but he gets it retroactively due to the points removal from Newgarden and McLaughlin.
T-65. Lee Wallard - 3
T-65. Jack McGrath - 3
T-65. Parnelli Jones - 3
T-65. Geoff Brabham - 3
T-65. Buzz Calkins - 3
T-65. Greg Ray - 3
T-65. Roberto Moreno - 3
T-65. Michel Jourdain, Jr. - 3
Wallard led after he won the 1951 Indianapolis 500 for three races.
McGrath took the championship lead from Bill Vukovich after the sixth race in 1953, led for three races before Sam Hanks surpassed McGrath.
Jones led for three races after he won the 1963 Indianapolis 500.
If you had no clue Geoff Brabham led the championship at any point, don't feel bad because he led for three races during the 1981-82 USAC Gold Crown Series when USAC was still trying to fight CART. The championship is recognized in IndyCar's record books. It counts.
Calkins won the inaugural IRL race in 1996 and led after all three races of that abbreviated season, sharing the last with Scott Sharp as mentioned above.
The 1999 IRL season is one of the roughest any series could have. In a ten-race season, none of the top six championship finishers finished in the top five of either of the first two races. The driver with the best average finish all season was 10.1. Ray opened the season with three consecutive 21st place finishes. He won three times and had five podium finishes but he finished outside the top twenty in his other five starts. He took the championship lead at the second Pikes Peak race with a victory and held on to lead the championship over the final three races.
At 41 years old, Moreno had a career year in 2000. He took the CART championship lead at Portland. In the next race, he picked up his first career victory in Cleveland. He held onto the championship lead for one more race and then finished third in the championship.
Jourdain, Jr. led the championship after the fourth race of the 2002 CART season when he opened the year with finishes of fourth, fifth, fifth and fifth. He would lead the championship again after his first career victory at Milwaukee the following season and he held it for the race after that as well.
T-73. Myron Fohr - 2
After Trenton and Springfield, the fourth and fifth races in the 1949 season.
T-73. Lloyd Ruby - 2
Ruby won the 1967 season opener in Phoenix, giving him the championship lead. The only other time he led was after the second race in 1969 at Hanford. He had finishes of third and second to open that season.
T-73. Wally Dallenbach - 2
Dallenbach is an odd case. In 1974 and 1975, the season opened with the California 500 qualifying races where the field was split in half. In 1975, Foyt won the first qualifying race and Dallenbach won the second. They were technically tied after the first two races but each had only made one start. There would be no tiebreaker to separate them. I am calling it a tie and two drivers were leading the championship at once.
The only time Dallenbach led on his own was after he won the fourth race of the 1977 season at Trenton.
T-73. Danny Ongais - 2
Ongais' magical 1978 season where he won five races was the only time he led the championship. He took the lead after winning the second race of the season at Ontario, and led after the third race at Texas World Speedway as well.
T-73. George Snider - 2
This goes back to the 1981-82 USAC Gold Crown Series season. Snider took the lead from Brabham in the penultimate race and Snider held on to win the championship.
T-73. Kevin Cogan - 2
Cogan won the 1986 season opener at Phoenix, lost the championship after Long Beach and then re-took the championship lead when he was second in the Indianapolis 500 to Bobby Rahal.
T-73. Davey Hamilton - 2
Hamilton took the championship lead from Mike Groff after the 1997 Texas race. Hamilton held onto the lead for one more race.
T-73. Adrián Fernández - 2
Fernández won the second round of 1998 in Motegi and he led after the following race at Long Beach as well.
T-73. Eddie Cheever, Jr. - 2
Cheever, Jr. won the 1999 IRL season opener from Walt Disney World Speedway. The only other time he led was after he won the sixth round of the 2000 IRL season at Pikes Peak.
T-73. Robbie Buhl - 2
Buhl was the first championship leader of the 21st century as he won the 2000 IRL season opener from Walt Disney World Speedway. He lost the championship after Phoenix but got it back a month later after the Las Vegas round.
T-73. Alexander Rossi - 2
For how close Rossi came to winning the 2018 championship, he only led the championship after two races, his victory at Long Beach and after the first Belle Isle race where he was third. Those are the only two times Rossi has led the championship in his career.
T-73. Scott McLaughlin - 2
McLaughlin won the 2022 season opener at St. Petersburg and held on to lead after the following race as Texas where he was second to Josef Newgarden by 0.0669 seconds.
T-73. Kyle Kirkwood - 2
The most recent new driver to lead the championship, Kirkwood led after his victory at Arlington last month, and he also led after Barber Motorsports Park. Álex Palou then re-took the championship lead when Palou won at Long Beach a few days ago.
T-86. John Andretti - 1
Andretti won the 1991 season opener at Surfers Paradise. It gave him the championship lead for one race.
T-86. Marco Andretti - 1

T-86. Henry Banks - 1
Banks entered the 1950 season finale from Darlington trailing Walt Faulkner by 107 points. Banks scored 280 points finishing third. Faulkner picked up 100 points in eighth. Banks won the championship by 73 points. It was the only time he led the championship in his career.
T-86. Gary Bettenhausen - 1
Bettenhausen led the championship after finishing fourth and first in the first two races of the 1972 season.
T-86. Raul Boesel - 1
Boesel finished fifth and fourth in the first two races of the 1988 season. It gave him a one-point championship lead over Mario Andretti and Al Unser, Jr., the drivers that won the first two races of the season.
T-86. Don Branson - 1
Branson opened the 1965 season with victory at Phoenix and it was the only time he led the championship in his career.
T-86. Pancho Carter - 1
Carter's one and only IndyCar victory was at Michigan in 1981. It gave him the championship lead for the only time in his career.
T-86. Jim Clark - 1
Clark won the 1965 Indianapolis 500. It paid 1,000 points. He held a 20-point lead over Mario Andretti, who had finished sixth, second and third over the first three races of that season.
T-86. Mark Donohue - 1
Donohue didn't take the championship lead when he won the 1972 Indianapolis 500, but he did take it after finishing second in the next race from Milwaukee... on tiebreaker. He held the championship lead on tiebreaker after the fourth race in the 1972 season. Donohue had the one victory and had 1,240 points. Joe Leonard had 1,240 points but his best finish over those four races was third at Indianapolis.
T-86. Robert Doornbos - 1

Herta led the championship after the third race in 2024 at Barber. He had finishes of third, second and eighth. He was only one point ahead of Will Power.
T-86. James Hinchcliffe - 1
The only time Hinchcliffe led was after he won the 2013 season opener from St. Petersburg, his first career victory.
T-86. Mike Nazaruk - 1
Nazaruk led the championship after the fourth race in 1951. Wallard retired after he won the Indianapolis 500 that year. Nazaruk had scored 1,003 points after the fourth race in Darlington, three more than Wallard and three more than Tony Bettenhausen, who had won the two races after Wallard's Indianapolis victory.
T-86. Max Papis - 1
Papis' first career victory was the opening round to the 2000 CART season in Homestead. It was the only time Papis led the championship in his career as well.

T-86. Takuma Sato - 1
The fever dream that was Sato's start to the 2013 IndyCar season saw him leading the championship after the fourth round in São Paulo. Sato had finished eighth, 14th, first and second. He would go on to finish 17th that year in the championship.
T-86. Chuck Stevenson - 1
Entering the 1952 season finale, Troy Ruttman held a 50-point championship lead despite being injured in August and missing the final six races of the season. All Ruttman needed was Stevenson to finish ninth or worse in the Phoenix finale to win the championship. Stevenson was sixth and won the championship by 30 points. It was the only time Stevenson led the championship.
T-86. Len Sutton - 1
Sutton's first career victory came in the 1958 season opener at Trenton. It was the only time he led the championship in his career.
T-86. Billy Vukovich, Jr. - 1
Vukovich, Jr. took the championship lead from Al Unser after the fourth race of the 1973 season at Indianapolis. Vukovich was runner-up at Indianapolis and it gave him a ten-point lead over Gordon Johncock despite Vukovich, Jr. having not won yet in his career. He had finished 15th, third, third and second in the first four races. Vukovich, Jr. would pick up his first, and only, career victory that September at Michigan.
T-86. Jeff Ward - 1
Jeff Ward even led the championship at some point! Specifically, it was after the 1999 Indianapolis 500. Ward had finished third, second and second in the first three races of that season. Ward's only career victory would come just over three years later at Texas!
That is everyone! All 107 drivers with some context behind when they led the championship. However, this experiment isn't over yet. We keep digging in a few days. There are a few more questions to answer.
