The Greatest IndyCar Drivers of All Time

Why comparing across IndyCar's eras is genuinely hard

IndyCar's history spans open-wheel racing on ovals, road courses and street circuits across more than a century, through the CART/IRL split of the 1990s and 2000s that fractured the sport's talent pool, and through car and safety technology that bears almost no resemblance to its earliest decades. See our complete guide to IndyCar for how the modern championship and points system actually work before diving into this comparison.

A.J. Foyt: seven championships, 67 wins, four Indy 500s

A.J. Foyt holds the outright record for IndyCar championships with seven, and his 67 career wins remain the all-time series record — a total built across an extraordinarily long and versatile career that also included NASCAR and sports car wins, making him one of the most genuinely versatile American racing drivers of any era. Foyt was also one of the first three drivers to win the Indianapolis 500 four times, a club that has never grown beyond four names since.

Mario Andretti: the only name on both an IndyCar and an F1 title

Mario Andretti won four IndyCar/Champ Car championships and the 1969 Indianapolis 500, but what genuinely separates his résumé from every other name on this list is that he also won the 1978 Formula 1 World Championship — making him the only driver in history to hold both an American open-wheel title and an F1 title. That cross-series dominance, sustained across decades, is part of why Andretti's name is still used as motorsport shorthand for raw driving talent, well beyond IndyCar's own fanbase.

Al Unser Sr: four Indy 500 wins across three different decades

Al Unser Sr matched Foyt's four Indy 500 wins, but did it across an unusually long span — from his first win in 1970 to his fourth in 1987, a 17-year gap that remains one of the most remarkable displays of longevity at the top of the sport. He also won three IndyCar championships, and his family's name is inseparable from Indy 500 history: brother Bobby Unser won it three times, and son Al Unser Jr won it twice, making the Unsers the winningest family in the race's history.

Scott Dixon: the modern era's win-and-championship machine

Scott Dixon sits one championship behind Foyt's record with six IndyCar titles, and as of 2026 has moved into second on the all-time wins list with 59 career victories, having already passed Mario Andretti's win total in recent seasons. He won the 2008 Indianapolis 500, holds the series record for career podium finishes, and holds the record for most career starts — a combination of longevity and consistency that makes him the clearest active-era rival to the sport's earlier legends, even without yet matching Foyt's championship count.

Other legends who belong in the conversation

Rick Mears joins Foyt and Unser Sr in the exclusive four-time Indy 500 winners' club, adding three IndyCar championships of his own and a reputation as one of the smoothest, most precise ovals drivers the series has ever seen. Hélio Castroneves became the fourth and most recent driver to reach four Indy 500 wins, doing so in 2021 after a 12-year gap since his third. And Dario Franchitti's four championships and three Indy 500 wins across the 2000s and early 2010s make him the strongest bridge between the CART/IRL-split era and today's unified championship.

How to actually weigh the comparison

Championships and win totals favor Foyt outright, but longevity, versatility and cross-series dominance are where Andretti's case gets stronger, and pure modern-era consistency is Dixon's real argument as his career total climbs closer to the all-time record. As with every "greatest of all time" debate on this site, the honest answer depends on which of those three qualities matters most to the person asking — and the fact that IndyCar can produce a genuine four-way argument like this, spanning drivers active across more than fifty years, is itself a sign of how deep the sport's talent pool has always run.
