Today, Studio 397 officially revealed Le Mans Ultimate Version 1.4, launching July 28, 2026, which is set to bring new American circuits, major online improvements, physics updates, and new features for RaceControl subscribers.
Le Mans Ultimate Version 1.4’s biggest addition is the U.S. Track Pass, a season pass that will introduce six American circuits across three content packs. The first pack includes Daytona International Speedway and WeatherTech Raceway Laguna Seca, both officially licensed and laser-scanned.
Each track pack is priced at $19.99, with the full season pass available for $44.99. Both options will receive a 10% launch discount during the first week, with RaceControl Pro+ subscribers getting all U.S. Track Pass content as it launches. Significant upgrades to the LiveSteward moderation system are coming as of the update, including more than 4,500 temporary bans issued since Version 1.3 through automated incident detection and review tools.
Le Mans Ultimate Version 1.4 also expands LiveSteward with additional rules designed to reduce false positives and improve live race management. Cars left stationary on track for extended periods will now be automatically returned to the garage to reduce on-track hazards.
The protest system has been overhauled, as players can now submit protests directly from replay mode by selecting the incident, identifying the driver, and attaching replay footage for stewards to review. Studio 397 said only intentional wrecking remains eligible for protests in public races, while standard racing incidents will continue to be handled through championship competition.
A new protest credit system replaces the previous cooldown. Players get three protest credits each month, and successful protests refund the credit used. All protests must be submitted within 24 hours of the incident.
Studio 397 has rebuilt the game’s online infrastructure with a new proprietary platform called RaceOS, replacing third-party backend technology. This now powers online features such as driver swaps, championships, hosted servers, daily races, and RaceControl services, with the platform being built specifically for racing simulations and future expansion.
The networking system now uses reliable UDP instead of TCP, which should help improve performance during close online racing and address long-term connectivity issues. Le Mans Ultimate Version 1.4 will also close a loophole that let players leave races to avoid damage or penalties, and give RaceControl Pro and Pro+ subscribers additional benefits.
The new Event Joker feature lets players remove the Driver Rank and Safety Rating impact from one completed race after earning a Joker every 10 races. Players can hold up to three Jokers, which are limited to single-driver events. Subscribers will also get access to Practice+ servers, which offer longer practice sessions beyond the standard race rotation.
The brake thermal model has even been updated to simulate brake disc surface and core temperatures separately with the goal of improving braking consistency, especially for LMP2, LMP3, and several Hypercar entries. Other quality-of-life improvements include automatic pit lane spawning at circuits without traditional garages, such as Daytona and Laguna Seca.
Le Mans Ultimate Version 1.4 also adds new pit lane procedures that require drivers to merge into the fast lane, along with Brazilian Portuguese localization. The update is set to deliver the final 2026 performance updates for the Alpine and Cadillac Hypercars, with the last two U.S. Track Pass content packs set to launch in the third and fourth quarters as work continues on the game’s online platform.
Le Mans Ultimate is available now on Steam for $39.99. For more information on this and other exciting racing simulators, be sure to check back to Simulation Daily
