iRacing launches eight new and returning fun series for Week 13

iRacing has unveiled a fresh lineup of unofficial series for Week 13, combining revivals of community favourites with newly designed events aimed at delivering varied racing experiences. The platform responded to user requests by curating a diverse slate of competitions across multiple vehicle classes and track types.

Two returning series headline the update. Battle of the Little Wings brings together lower-formula machinery—FIA F4, Super Formula Lights, and Skip Barber Formula 2000—on shorter circuits, with drivers competing both within and across class categories. Ridiculousness returns with IMSA WeatherTech SportsCar Championship prototypes and GT3s tackling tight oval layouts at Bristol, Dover, and Milwaukee.

Six new series expand the Week 13 offering. The Doctor's Office pairs the Dallara P217, Ligier JS P320, and Ferrari 296 Challenge on iconic road courses. To The Streets focuses on precision driving with the Dallara IL-15 on street circuits, with plans to rotate vehicle types in future seasons. Manufacturer Madness groups multiple Ford models—stock cars, GT cars, and sports cars—on American road and street layouts, with different manufacturers featured in subsequent seasons.

Incident Limit Challenge penalises every contact and corner-cut with drive-through penalties, using the Toyota GR86 at Lime Rock Park's Chicanes layout. Storm Chasers emphasises wet-weather performance, featuring the BMW M2 Racing (G87) on Oulton Park's International layout in 15-minute sprints. Free for All rotates between licence types using included content; the current season features the FIA Cross Car, Pro 2 Lite, and Volkswagen Beetle Lite on dirt road courses.

The full Week 13 schedule is available on the iRacing website.
