AI Racing

With iRacing AI you can race against highly adjustable computer-controlled drivers!

What AI content comes with iRacing AI?

By default, iRacing provides you with an Official AI Season. This AI Season may be used as is, customized as you’d like, or simply used as a reference for creating your own unique AI content!

Running an Official AI Season will create a copy of the Official AI Season with your results. Official AI content can be copied and customized, but cannot be deleted.

When I use a Car Class AI Opponent Roster, how is iRacing generating the AI Drivers?

iRacing AI comes equipped with a pre-set list of AI Drivers that it uses to fill Car Class AI Opponent Rosters so you can get on track immediately. These AI Drivers are given reasonable settings to keep the racing both fun and competitive. However, you can also randomly generate an AI Opponent Roster, or build your own from scratch if you’re looking for a new challenge.

If you’re feeling adventurous, you can create your own roster of up to 60 AI Opponents to compete against. Custom AI Opponent Rosters include custom paint jobs, adjustable driver personalities, customizable racing skills, and much more. Finally, please keep in mind iRacing AI continues to develop – using very large fields of AI Opponents may have an impact on your frame rate as well as cause some unpredictable AI behavior.

How do I adjust the skill level of the AI Opponent Roster for an event?

When you are creating the AI event, on the “Set AI” step, adjust the Skill Spread values to a minimum and maximum value that fit your driving skill. This will automatically scale all AI Opponents to have a driving skill value within the Skill Spread range.

Can I share my user-generated iRacing AI Seasons with my friends?

Yes! When a new iRacing AI Season is saved, it creates a new AI Season file on your computer. You can find these files in the following folder location: …\Documents\iRacing\aiseasons.

Here, you will see a series of .json files, each with the name of one of your AI Seasons. You can easily share these “.json” files with anyone you wish; just have them save the file inside their own …\Documents\iRacing\aiseasons folder. Then, next time they launch iRacing via the iRacing UI, and navigate to the AI Racing section, they will see the AI Season in their iRacing Simulator! If you had run any of the events in the AI Season before sharing the file out, your race results will be included in the AI Season. If you want to send a fresh AI Season without your results in it, simply use the “Copy” button on the AI Season first to generate a fresh AI Season, then share that one.

Does the Simulator look any different when running iRacing AI?

When you start an AI Racing event, the interface is almost entirely the same, with just a few added options. Once loaded into the Simulator, on either side of the usual Practice/Qualify/Race button, you will see a “Prev” button and “Next” button. You can use these to go back to the previous session, or skip ahead to the next session. For example, if you have a bad start and want to try again, use the “Prev” button to restart the Race, or, if you get a great Qualifying lap and are ready to move to the Race, click the “Next” button.

Can I pause my race?

Since you are actually the only human out on the track, yes! While you’re driving, you can use the Pause hotkey on your keyboard to freeze the simulation if you need to step away.

Note: This will not work in hosted or league sessions.

Can I re-run a bad race after it’s complete?

Yes! If you want to re-run an event in your AI Season before moving on to the next one, use the “Re-run Last Race” option to give it another try.

Help! I lost my iRacing-provided AI content!

If you don’t see any Official iRacing AI content when you first launch the iRacing UI after an update, log out, close the iRacing UI, and try relaunching it again.
