By now, Marco Andretti has carved out his own lane in the IndyCar world.
The Pennsylvania native was once the youngest driver in Indy Racing League history, which later became IndyCar. For years, Andretti was a mainstay at some of the biggest IndyCar races out there. Nowadays, he only competes in the Indy 500, also making some NASCAR appearances in recent years.
Andretti had the benefit of some legendary racing experience in his family as he ascended in IndyCar, from his grandfather, an International Motorsports Hall of Famer, to his father, a current team owner and one of the greatest drivers of the CART era.

Marco Andretti family tree
Here's a breakdown of Marco Andretti's family tree.
Marco Andretti grandfather
Andretti's grandfather is Mario Andretti, a former driver who competed for both Formula One and IndyCar.
Mario Andretti, now 85, was born in Italy with a twin brother, Aldo. He moved with his family to the United States in 1955, and they settled in Nazareth, Penn. Andretti later gained U.S. citizenship, finding a passion for racing alongside Aldo and beginning to compete in dirt track racing at age 19.
Andretti broke into IndyCar, known as the USAC National Championship at the time, in 1964 by getting a spot start in the Trenton 100, finishing 11th. Midway through the 1964 season, he began to impress one of the top teams, Dean Van Lines Racing Division, and he wound up competing in the final eight races before earning Rookie of the Year honors.
Andretti began to rack up USAC IndyCar titles, winning 29 of 85 USAC championship races between 1966-69. He became the youngest IndyCar champion in history, a record that held for 30 years.
Mario Andretti was much more than an IndyCar driver, though. He remains just one of two drivers to win the Daytona 500, which he did in 1967, while not being a full-time stock car driver.
He also joined Formula One for the first time in 1968 by competing in the United States Grand Prix, winning pole position. He ultimately had to retire from that race due to mechanical issues, but he went on to become a full-time F1 driver in 1975. Over his F1 career, he won one championship (1978), 12 races, and 18 pole positions.
Andretti also returned to IndyCar in 1979, which was then owned by CART, to continue his racing career into the 1990s, and he competed in the 24 Hours of Le Mans for decades.
All things told, Mario Andretti owns one of the most legendary racing careers ever. He had over 100 wins on major circuits and remains the only driver to win the Indy 500, Daytona 500, and the Formula One World Drivers' Championship. Moreover, he's one of just two drivers to win a race in Formula One, IndyCar, the World Sportscar Championship, and NASCAR.
Among the awards Andretti won were Driver of the Century by the AP in 1999, U.S. Driver of the Year in multiple decades, and an induction into the International Motorsports Hall of Fame in 2000, among other halls of fame.
Mario Andretti also supported his family's racing endeavors over the years, and nowadays, he's a member of the Cadillac Formula One Team, which will join F1 in 2026.
Marco Andretti dad
Marco Andretti's dad is Michael Andretti, yet another legend in the racing world. Michael, now 62, was born in 1962 in Pennsylvania to Mario and Dee Ann Andretti. He graduated from Nazareth High School before following in his father's footsteps in racing.
Michael Andretti began as a kart driver, winning 50 of his 75 races over eight years before moving to cars. From Formula Vee to racing alongside his father in various high-profile races, Andretti's career got off to a quick start.
In 1983, Andretti made his CART debut for the Kraco Enterprises team. He would share the Rookie of the Year award that season with Roberto Guerrero, and his first IndyCar win was the 1986 Toyota Grand Prix of Long Beach. Over his CART career, Andretti would win 42 races, 32 pole positions, and the 1991 championship. He came close to winning the Indy 500 on various occasions, but he could never finish first. He now holds the record for most laps led in the Indy 500 without having achieved a victory.
Andretti also competed in Formula One in 1993, logging just one podium before returning to IndyCar in 1994. He would retire from full-time racing in 2003, still competing in the Indy 500 for a few more years as his son, Marco, became a rookie. However, his bad luck continued at the race, and in 2007, Michael Andretti announced that that year's Indy 500 would be his last.
Andretti has gone on to own the team "Andretti Autosport," which later became Andretti Global as it pursued entry into F1. In 2024, Andretti sold the team, saying he would remain involved as a strategic advisor. He has been inducted into the Indianapolis Motor Speedway Hall of Fame, along with a few other honors.
Andretti had two children with his first wife, Sandra Spinozzi: Marco and Marissa. He also had a son, Lucca, with his second wife, Leslie Wood, and twin children, Mario and Miati, with his now-wife Jodi Ann Paterson.
Marco Andretti uncle
Jeff Andretti is the son of Mario Andretti, the brother of Michael Andretti, and the uncle of Marco Andretti.
Now 61, Jeff Andretti began his racing career in 1983 with Formula Fords, also racing for Formula Super Vee, the American Racing Series, and the Toyota Atlantic as his career grew. He joined CART in 1990 for the first time, joining Mario and Michael to make history as the first time a father had competed against his two sons in a CART race.
In 1991, Jeff Andretti won Rookie of the Year at the Indy 500, making him the third Andretti family member to earn the title. However, in 1992, he suffered leg injuries after crashing into a wall at Indianapolis Motor Speedway.
While Jeff Andretti did return to racing after his accident, even setting an unofficial closed-course speed record for IndyCars at 234.50 mph in 1993, his career was never quite the same. He competed in various other races before retiring. Andretti is now a driving instructor after his CART career lasted from 1990-94.
Other Andretti family members
The Andretti legacy in racing runs even deeper. Aldo Andretti, Mario's brother, had two sons, John and Adam Andretti.
John most extensively competed in NASCAR, winning two of his 393 career races, the first of which was the 1997 Pepsi 400. Like many of his family members, John Andretti also spent some time with IndyCar and CART. John Andretti had individual wins in CART, IMSA GTP, Rolex Sports Car Series, and NASCAR during his career. He died in 2020 of colon cancer.
Adam Andretti, meanwhile, has also raced in sports cars, Indy Pro Series, NASCAR, and Stadium Super Trucks over his career. The 46-year-old most recently competed for Stadium Super Trucks in 2018.
In 1991, the Andrettis became the first family to have four relatives compete in the same CART series.
