iRacing Season 3 2026: New Cars, a Rebuilt Laguna Seca, and the Features Endurance Racers Have Been Waiting For

iRacing's Season 3 2026 build is arriving in early June, and this one is different. This isn't a minor patch with a couple of paint scheme updates and a bug fix list — it's one of the most feature-rich quarterly updates the platform has delivered in recent memory. A from-scratch rebuild of Laguna Seca, four new cars including the BMW M2 Racing and Euro NASCAR RC01, the long-awaited arrival of Dirt AI, built-in fuel calculators, dynamic track maps, overhauled multi-class starts, and infrastructure upgrades that will reduce latency across the board. For anyone running a professional-grade simulator — and especially for endurance racers — this build has something meaningful in almost every category.
