From Andretti to Castroneves, the Legendary Drivers of IndyCar

When we speak of IndyCar's legendary drivers, the names that come to mind are those who reached four Indy 500 victories, such as A.J. Foyt, Mario Andretti, Al Unser, and Rick Mears; today, Hélio Castroneves and Josef Newgarden come to the fore. This guide tells the story of American open-wheel racing's legends not through their championship counts, but through their styles, their eras, and the legacies they left behind.

Who is IndyCar's legendary driver? This is exactly where the debate begins

Let me ask you a question first: Would you declare as "the greatest" someone who won four Indy 500s and then racked up victory after victory in NASCAR, or someone who swept championship after championship in the world's toughest disciplines? That is precisely what makes IndyCar history so much fun - it has no easy answer.

Some historians say, unquestionably, A.J. Foyt: he has more Indy 500 victories than Mario Andretti (4-1), and more combined IndyCar and NASCAR wins (67 versus 52). But don't skip one detail: Foyt never raced for a world championship. Mario, however, reached the top of Formula 1 in 1978. So comparing them is like comparing apples to oranges - both are great, but great in different ways. Mario's answer to this, I think, settles every debate: "Today's champions would win yesterday, and yesterday's would win today. There is no such thing as 'this era is better.'"

A.J. Foyt: No one raced through a greater period of change

Let me make an analogy to describe Foyt's career: Imagine someone doing the same job from the era of rotary phones all the way to the smartphone era. He entered his first Indy 500 in 1958, in an era when speeds were around 143 miles per hour; his last came in 1992, in an era when speeds had surged to 223 miles per hour. Consider the technological revolution in between - no one stayed at the top for so long amid such enormous change.

The numbers are staggering: 67 Champ/Indy car victories, and seven national championships. He took his first four Indy 500 wins in 1961, 1964, 1967, and 1977. And there is one record that is nearly impossible to repeat: he is the only driver to win the Indy 500, the Daytona 500, the 24 Hours of Le Mans, and the 24 Hours of Daytona. Don't ask whether it's on ovals, on asphalt, or in endurance - he won them all.

The man who built a team while still a driver

Foyt didn't settle for just driving. In 1965, at age 30, he founded his own team and, while still a driver, won two Indy 500s (1967, 1977) and three IndyCar championships (1967, 1975, 1979). That meant a driver also dealing with his own car's engineering and strategy - much like a student both writing the exam and handling the book's printing. The team stayed in family hands when his son Larry Foyt joined in 2006 and rose to team president in 2015, and in 2026 it celebrates its sixth decade.

Mario Andretti: Driver of the 20th Century

When you look at Mario Andretti's record, you can't believe your eyes: in IndyCar, 52 wins, 65 pole positions, 141 podiums. A total of 109-111 victories across the major disciplines. Four national championships, the 1969 Indy 500 win, the 1978 Formula 1 world championship, plus a Daytona 500 and a 24 Hours of Daytona victory. This variety is like someone winning Olympic gold in swimming, running, and cycling.

But one record, to my mind, is far more meaningful: Mario is the only person named "US Driver of the Year" in three different decades (1967, 1978, and 1984). In other words, he was considered the country's best at the beginning, middle, and end of his career. In the end, the voting also handed him the "Driver of the Century" title - and that title, in my view, is the strongest answer to the "no world championship" objection in the Foyt debate.

Your career is judged by your performance there. Despite my seven championships, I am always called 'the 1969 Indy 500 winner.'

This quote sums up the Indy 500's place in this sport in a single sentence. In Foyt's words, "The 500 made A.J. Foyt; it's like the Kentucky Derby." Scott Dixon's comparison is just as fitting: the track is "our holy ground, like Augusta National in golf."

Al Unser and Rick Mears: Two different legends with four wins each

Al Unser Sr. caught up with Foyt with his fourth Indy 500 win in 1970, becoming the second member of the "four-win club." His son Al Unser Jr., with his 1992 and 1994 Indy 500 wins, two CART championships, and two IROC championships, carried the family name to the top once again. This second generation racing against their fathers - Unser Jr. and Michael Andretti - created, according to historians, a parallel "likely never to be repeated."

Rick Mears, meanwhile, is the club's quiet but technically most refined member. Four Indy 500 wins (1979, 1984, 1988, 1991), 29 career victories, and a track record of 6 pole positions that still stands. He started from the front row in 11 of his 15 races between 1978 and 1992 - his first win in 1979 came directly from pole. As a statistics fan, let me say this: such consistency is far harder than one-off brilliant victories. In 1988, he also delivered Chevrolet's first Indy 500 win. Throughout his career, he always emphasized the contribution of Bill Simpson, one of the architects of the safety equipment revolution.

Michael Andretti: The legend who never won the Indy 500

Now let me tell you the most heartbreaking part of this guide. Michael Andretti, with 42 CART wins, third on the all-time wins list - behind only Foyt and his father Mario. 1991 CART champion; runner-up five times in 1986, '87, '90, '92 and '96. But the Indy 500? He never managed to win it.

The most interesting part: He led more laps than many multiple Indy 500 winners. In other words, he ran races at the front, but luck always knocked on another door - even in his final race, the engine left him halfway through. He also had a brief F1 adventure in 1993 as Senna's teammate at McLaren; the third place at Monza was the highlight of both that season and his final F1 race. In my view, his story is the finest example of the sport's lesson that "racing is sometimes not just about speed."

From Castroneves to Newgarden: Today's representatives of the four-win club

For many years, the list of names to reach four Indy 500 victories was limited to three people: Foyt, Unser and Mears. Then Hélio Castroneves joined the ranks - winning back to back in 2001 and 2002 to become the fourth name on the list, and he remained the last back-to-back winner for many years. Back-to-back victories are so hard that it is like finishing first at university two years in a row: the car changes, the rules change, the rivals change, but the expectation stays the same.

That is, until Josef Newgarden. Newgarden won in 2023 and 2024, becoming the first back-to-back Indy 500 winner since Castroneves and proving that this tradition is alive today. In this race, run since 1911 and known as "The Greatest Spectacle in Racing," the tradition of drinking milk after victory also continues - a ritual that paints a creamy white smile on the winner's face, unlike anything else in the world.

The all-time top five winners

Let's gather the numbers in a single table - together, these five names accumulated a total of 239 wins, 20 series championships and 10 Indy 500 victories:

The F1-IndyCar bridge: Names who conquered both worlds

IndyCar's legendary ledger is intertwined with the pages of F1. Far from few are the names who crossed from this series to Formula 1 or vice versa and found success: Nigel Mansell, Emerson Fittipaldi, Alex Zanardi, Bobby Rahal, Jim Clark, Dan Gurney, Alexander Rossi and Justin Wilson all crossed this bridge. Mario Andretti's 1978 championship is undoubtedly the peak of this traffic.

The reverse direction is packed as well: Bourdais joined IndyCar in 2011, Barrichello in 2012; Juan Pablo Montoya returned in 2015 - having previously won 7 races in F1 for Williams and McLaren between 2001 and 2006. Danny Sullivan and Mark Donohue are also among the names who went from IndyCar to F1. The reason these moves feel so natural is simple: Both series host the world's most talented drivers, only their philosophies differ - one sells global visibility, the other variety and racing intensity.

Where is the legendary tradition heading in 2026?

Today, the series' agenda is who can stop Alex Palou's back-to-back domination. But I think the truly delightful news is this: a "Legends Day" event is being planned at the Indianapolis Motor Speedway on May 23 - meaning they are celebrating the legends as part of a tradition that is still alive. With Foyt's team stepping into its sixth decade, Newgarden's hunt for a fourth title with the new generation, and Dixon still being in the top five, this tells us one thing: This family tree is not ending, it is only opening new branches.

So if it were up to you, who would you choose as "the greatest"? In my opinion, don't look for the answer in the list below - look for it in that cold bottle of milk handed out at the end of the 500 miles.
