iRacing Week 13 Caps Off 2021 Season 4

Featuring our usual mix of new content and feature-focused series, a handful of official events to keep your skills sharp, and our typical slate of revolving fun-first series, iRacing Week 13 is back to wrap up 2021 Season 4!

For those who are new to iRacing, Week 13 is the week between each of our four seasons where we deploy everything new for the coming season. It’s also a chance for us to experiment with cars and tracks in new or unexpected combinations, like swapping tracks for oval and road vehicles or out-of-this-world multi-class combinations. Many of these are unofficial series, meaning they won’t affect your iRating as you have a bit of fun, and don’t worry—your favorite series may be on a week hiatus, but it’ll come back for the start of the new season.

Here’s a look at everything to watch for during build week:
