Here are the key differences between F1 and IndyCar

Formula One and IndyCar are the highest levels of open-wheel racing in the world. F1 competes worldwide, and IndyCar competes in North America.

The 2023 IndyCar schedule includes 17 races, starting on the streets of St. Petersburg, Fla., in March, and finishing at WeatherTech Raceway Laguna Seca on Sept. 10. Races are run on downtown streets, road courses and oval speedways.

The 2023 F1 schedule includes 23 races in 20 nations/principalities, starting with the Bahrain Grand Prix in March and finishing with the Abu Dahbi GP in November. Most races are on road courses, though some are on downtown streets (Monaco, Las Vegas). F1's increased popularity in the United States is evidenced by three races in 2023: in Miami on May 7; Austin, Texas, on Oct. 22, and Las Vegas, on Nov. 18.

When is the Indy 500?

The 200-lap race on the 2.5-mile Indianapolis Motor Speedway oval is scheduled for Sunday, May 28, 2023. That's the same day of F1's premier race of the season, on the streets of Monaco.

Can IndyCar drivers go to F1?

Several current IndyCar drivers previously raced in F1 ‒ including Indy 500 champions Takuma Sato, Alexander Rossi, Marcus Ericsson, as well as Romain Grosjean. It hasn't worked the other way around recently, though Alex Palou, Colton Herta and Pato O'Ward are eager to try.

IndyCar drivers Marcus Armstrong, Callum Ilott and Christian Lundgaard have raced in F2, one level down from F1.

IndyCar vs. F1 salary

IndyStar reported in 2021 that 2009 Indianapolis 500 champion Scott Dixon had a salary in the $3.5 million-$4.5 million range, the highest in the series at the time. A more common pay structure among the series' drivers is that they must bring millions of dollars of sponsorship to their team, and they get a cut of it, and they could get performance bonuses.
