iRacing 2025 Season 2 Week 13 Schedule Released

Looking forward to getting behind the wheel of our newest cars and tracks? The latest edition of iRacing Week 13 has you covered with all sorts of fun new weeklong championships!

For our newest racers, iRacing Week 13 is our week between the four quarterly iRacing seasons where we debut new content, give our most serious racers a week to recharge between championships, and have some fun with a handful of out-of-the-box ideas. Longtime favorites include Battle of the Little Wings for those who want to run multi-class Formula Car events, Figure GR8 for those who enjoy Irwindale and Slinger’s most unique layouts, and of course the Ridiculousness and Dirt Ridiculousness series for the wildest combinations of all.

New series for this Week 13 include 5 to Go, an exciting five-lap shootout at Daytona that alternates between various modern NASCAR machines and the newly released Gen 4 Chevrolet Monte Carlo and Ford Taurus. In addition, the Sleeves Off Scramble will put up to 60 Volkswagen Jetta TDI Cup cars on track together at Langley Speedway—what could go wrong?
