iRacing: Which Formula Series Should You Choose?

The world of single-seater racing in iRacing offers a wide variety of categories, ranging from Formula 4 (F4) to more advanced series such as Super Formula Lights (SFL) and Indy NXT.

Each of these categories stands out not only for the technical characteristics of the cars but also for the type of drivers they attract, which directly affects the level of racecraft and on-track behavior.

F4: The Chaotic Entry Point

F4 is often considered the “school” of open-wheel racing. Its accessibility, both in terms of handling and cost of entry, attracts a large number of beginner drivers.

This makes races unpredictable, with frequent first-lap crashes and a high incident rate.

Although the car itself is relatively easy to drive, the lack of experience from many participants turns this series into a chaotic environment where surviving the opening laps is often the main challenge.

Super Formula Lights: A Step Toward Maturity

SFL represents an intermediate stage.

Since it requires a higher license level and some experience, it usually attracts more disciplined drivers. While incidents still occur, the overall standard of respect and clean racing is superior compared to F4.

The car is not the most extreme in terms of speed, but it offers a balanced mix of power, control, and strategy, which allows for more tactical races.

Indy NXT: Demanding and Rewarding

Indy NXT is one of the most challenging categories in the service.

Its car is significantly more powerful and technically complex, with demanding braking zones, tricky acceleration phases, and turbo behavior that requires finesse.

This makes it a car with a steep learning curve but one that offers highly rewarding experiences once mastered.

Although mistakes are heavily punished, the overall racing tends to be more organized than in F4, as most participants come with previous experience in mid-to-high-level open-wheel cars.

General Comparison

• F4: High level of chaos, good for beginners, but frequent incidents.
• SFL: More disciplined environment, balanced between accessibility and seriousness.
• Indy NXT: Demanding, technical, and rewarding; closer to professional-level racing.

The choice between F4, SFL, and Indy NXT depends on what each driver is looking for.
