iRacing Season 3 2026 brings a full ground-up rescan of Laguna Seca. The existing version has been in the iRacing library for years. It has been a constant in road racing series across the platform. The rescan replaces it entirely with a high-resolution capture. Laguna Seca now matches the newer track builds iRacing has released in recent seasons.
What a Ground-Up Rescan Actually Means
iRacing’s newer track builds use laser scanning technology. Specifically, it captures the real-world surface in millimeter-level detail. Every bump, camber variation, and surface irregularity at the real venue gets recorded. Older tracks were built to an earlier standard. They were accurate for their time but do not match the fidelity of more recent builds. A ground-up rescan is not a minor update. The existing geometry is set aside. The track is rebuilt entirely using current scanning data and current art standards.
In particular, for Laguna Seca, this means the Corkscrew, the sweepers through Turns 2 and 3, and the surface variations throughout the lap all receive full detail treatment. Drivers familiar with the current version should expect differences. The biggest changes will come where the sim currently shows a smooth surface but the real track does not.
A Track Worth the Investment
Additionally, Laguna Seca holds a significant place in both real-world and sim racing history. The Corkscrew is one of the most recognizable corners in motorsport. It drops sharply from a blind crest through a tight left-right chicane. The track has hosted IMSA, IndyCar, and decades of club racing. In iRacing it appears in sports car, prototype, and GT series. It consistently produces technical, competitive racing where track knowledge matters.
The Laguna Seca iRacing rescan also updates the track art to reflect how the venue looks today. Landscaping, signage, tire wall placement, and run-off configurations all change over time. The new version reflects the current state of the facility rather than how it looked at the time of the original build.
Part of a Broader Rescan Program
Laguna Seca is not the only track in the rescan pipeline. iRacing has also confirmed Mid-Ohio, Road America, and Milwaukee are coming. Paul Ricard scanning was planned for the month following the May update. iRacing has been working systematically through its existing track library. Laguna Seca is among the highest-profile tracks to receive this treatment. Season 3 is live now.
