iRacing to Introduce Aston Martin Valkyrie AMR-LMH and Caterhams in 2026 Season 4
The 2026 Season 4 update for iRacing will feature the Aston Martin Valkyrie AMR-LMH, two Caterham models, complete overhauls for three circuits, and several quality-of-life gameplay improvements.
Development team at iRacing has outlined the upcoming content additions planned for the 2026 Season 4 release. The headline addition to the service is the Aston Martin Valkyrie AMR-LMH hypercar. The prototype is expected to enter the IMSA iRacing Series as well as future special events, with Petit Le Mans in the second week of the season anticipated to be among the car's first major competitive appearances.
Grassroots sports car racing also receives a boost with the introduction of Caterham. Players who purchase the vehicle will receive two distinct variants: the Caterham Academy targeted at Class D competition, and the more powerful Caterham 420R for Class C series.
While no brand-new tracks built from scratch are scheduled for this release, three existing venues will undergo full overhauls: Road America, Mid-Ohio Sports Car Course, and the Milwaukee Mile. Current owners of these circuits will receive the updated versions without any additional cost. In addition, visual refreshes are slated for Summit Point and Road Atlanta.
The update also touches several existing cars on the platform, bringing revisions to the Mazda MX-5 Cup, Gen 4 Cup, and the Sprint Car. The Gen 4 platform will gain a Grand National specification, which will be provided free of charge to existing base model owners.
On the feature side, Season 4 will introduce multi-stage pace car rolling starts, an updated Pit Summary screen detailing estimated pit stop durations and repair times, and a new graphical vehicle damage indicator.
