IndyCar vs. Formula 1: A 2026 Comparison

Both IndyCar and Formula 1 represent the pinnacle of open-wheel racing, captivating audiences worldwide with speed, skill, and technological innovation. Even as both series share a common foundation, significant differences exist in their approaches to racing, car design, and global reach. This article provides a comprehensive comparison of the two series as of 2026, examining key aspects from schedules and car specifications to driver salaries and the potential for crossover.

2026 Season Overviews

The 2026 IndyCar schedule consists of 18 races, strategically distributed between road courses, street circuits, and oval tracks. The season kicks off in March in St. Petersburg, Florida, and concludes in September in Monterey, California. IndyCar primarily competes in North America, with a single race in Canada. In contrast, the 2026 Formula 1 schedule is more extensive, comprising 24 races on road and street courses across five continents and 21 nations. Three races are held in the United States: Miami, Austin, Texas, and Las Vegas. The F1 season begins in March in Australia and culminates in December in Abu Dhabi.

The Indianapolis 500

The iconic Indianapolis 500, a 200-lap race on the 2.5-mile Indianapolis Motor Speedway oval, is scheduled for May 24, 2026. Alex Palou won the Indy 500 in 2025. Notably, Formula 1 will also race in Canada on the same day, a departure from its traditional premier race in Monaco (held on June 7 this year).

Driver Movement and Opportunities

The possibility of drivers transitioning between IndyCar and Formula 1 exists, though it’s not always straightforward. Several current IndyCar drivers, including Indy 500 champions Alexander Rossi and Marcus Ericsson, have prior Formula 1 experience. More recently, Colton Herta has moved from IndyCar to Formula 2, a stepping stone towards Formula 1. Conversely, Formula 1’s Fernando Alonso has participated in two Indianapolis 500 races.

Driver Salaries

Driver salaries in both series are often confidential. However, reports indicate that in 2025, Pato O’Ward led IndyCar drivers with an estimated $5 million salary, followed by Scott Dixon ($3.5 million-$4.5 million) and Kyle Kirkwood ($3.5 million). A common structure in IndyCar involves drivers securing sponsorships, receiving a percentage of the funding, and earning performance-based bonuses. Formula 1 driver salaries generally start around $1 million annually, with top drivers earning significantly more.

Car Specifications: IndyCar vs. Formula 1 (2026)

Significant differences exist in car dimensions and engine technology:

• Dimensions: IndyCar cars maintain a wheelbase of 117.5-121.5 inches and a width of approximately 76 inches, weighing between 1,635 (road/street) and 1,785 (oval) pounds. Formula 1 cars are shorter with a 134-inch wheelbase and narrower at approximately 75 inches, weighing around 1,700 pounds.
• Engine: IndyCar utilizes a 2.2-liter twin-turbocharged V6 engine with a hybrid system, producing over 800 horsepower. Formula 1 continues with a 1.6-liter V6 turbo hybrid engine, aiming for a roughly equal power split between the combustion engine and an electric motor, generating approximately 1,000 horsepower.
• Tires: IndyCar employs Firestone tires, with primary sets for durability and alternate sets for speed. Tire diameters are 15 inches, with front tires slightly over 10 inches wide and rear tires slightly over 14 inches. Formula 1 uses 18-inch Pirelli tires, narrower than previous models, with varying compounds (soft, medium, hard) for different grip and wear characteristics.
• Fuel: IndyCar is committed to sustainability, using 100% renewable fuel derived from ethanol, sugarcane waste, and other bio-feedstocks. Formula 1 is transitioning to sustainable fuel made from carbon capture, municipal waste, and non-food biomass.

Performance: Speed and Technology

IndyCar cars can reach speeds exceeding 240 mph on oval tracks, with Robert Shwartzman achieving a 2025 Indy 500 pole position speed of 232.790 mph. While previous F1 cars could accelerate from 0-200 mph in approximately 4.5 seconds, lap speeds are generally slower due to the nature of road and street courses. IndyCar cars often prioritize higher speeds, while Formula 1 focuses on advanced aerodynamics and cornering capabilities.

Key Differences Summarized

Looking Ahead

Both IndyCar and Formula 1 continue to evolve, embracing new technologies and striving for greater sustainability. With increasing American interest in Formula 1 and IndyCar, and with former F1 drivers finding success in the Indy 500, the future promises exciting competition and potential for increased international crossover within both series.
