iRacing’s Season 3 2026 development update confirmed that Laguna Seca is being rebuilt from the ground up with a full rescan of the current track surface. The existing Laguna Seca version has been in the iRacing library for years and has been a constant in road racing series across the platform. The rescan replaces it entirely with a high-resolution capture, bringing Laguna Seca in line with the newer track builds iRacing has been releasing over recent seasons.
What a Ground-Up Rescan Actually Means
iRacing’s newer track builds use laser scanning technology to capture the real-world surface in millimeter-level detail. The resulting data includes the exact profile of every bump, camber variation, and surface irregularity present at the real venue. Older tracks in the iRacing library were built to an earlier standard and, while accurate for their time, do not match the surface fidelity of more recent additions. A ground-up rescan is not a minor update: the existing geometry is set aside and the track is rebuilt entirely using current scanning data and current art standards.
For Laguna Seca specifically, this means the Corkscrew, the sweepers through Turn 2 and 3, and the surface variations throughout the lap will all be represented with a level of detail the current version cannot provide. Drivers who have spent many laps at the current Laguna Seca should expect to notice differences, particularly at points where the track surface in the sim is smooth but the real track is not.
A Track Worth the Investment
Laguna Seca holds a significant place in both real-world and sim racing history. The Corkscrew, which drops sharply from a blind crest through a tight left-right chicane, is one of the most recognizable corners in all of motorsport. The track has hosted IMSA, IndyCar, and decades of club racing, and it regularly appears in discussions about the best purpose-built road racing circuits in the world. In iRacing it has been used in sports car, prototype, and GT series for years and tends to produce technical, competitive racing where track knowledge is a genuine advantage.
The rescan also updates the track art to reflect how Laguna Seca looks today rather than at the time of the original build. Landscaping, signage, tire wall placement, and run-off configurations change over time, and the new version will reflect the current state of the facility.
Part of a Broader Rescan Program
The Season 3 development update also confirmed that Mid-Ohio, Road America, and Milwaukee are all in the rescan pipeline, and that Paul Ricard scanning is planned for the month following the May update. iRacing has been systematically working through its existing track library and applying current standards to older builds. Laguna Seca is among the highest-profile tracks to receive this treatment. Season 3 is expected to go live in the coming weeks.
