iRacing 2026 Season 4 Update Released: Full Release Notes

iRacing has released the 2026 Season 4 build, bringing one of the largest quarterly updates of the year with four new cars, three completely rebuilt circuits, major vehicle and track refreshes, multi-threaded physics processing, new UI tools, expanded AI support and hundreds of individual changes across the simulator.

The 2026 Season 4 Initial Release, build 2026.09.09.01, was published on September 9, ahead of the new competitive season officially beginning on September 15 at 00:00 UTC.

• Four new cars headline the update: the Aston Martin Valkyrie AMR-LMH, Caterham Academy, Caterham 420R and Gen 4 Grand National. Road America, Mid-Ohio Sports Car Course and The Milwaukee Mile have meanwhile been completely rebuilt using new laser-scan data, while Road Atlanta and Summit Point Raceway receive substantial visual overhauls.
• One of the biggest changes under the surface is the introduction of multi-threaded physics processing. iRacing says its new Physics Islands system can reduce CPU physics overhead by 50% or more in large grids and heavy-traffic situations across a wide range of hardware.
• Season 4 also introduces the Pit Summary and Car Damage widgets, Minimal UI mode, Reference Car UI, improved Fuel Calculator and Track Map tools, support for 16 car classes in several interface elements, new Start Zones at more than 50 circuits and preparations for multiclass starts using dedicated pace cars for each class.
• The latter system will first undergo a final test during Week 13’s iTested series before being introduced to selected official championships, beginning with the IMSA iRacing Series.

Below are the complete iRacing 2026 Season 4 Initial Release Notes.

iRacing 2026 Season 4 Initial Release Notes [2026.09.09.01]

Modified: September 9, 2026 at 8:37 AM

The iRacing 2026 Season 4 Release Build is moving out onto the track! This is one of four major annual releases for iRacing, and it adds new content, features, upgrades, and a hauler-full of fixes and tweaks. iRacing 2026 Season 4 officially starts on September 15th at 0000 UTC!

iRacing welcomes FOUR brand new cars into our garage, including the Aston Martin Valkyrie AMR-LMH, two versions of the Caterham – Academy and 420R, and the Gen 4 Grand National. A diverse set of vehicles showcasing the many ways drivers race!

We’ve also added THREE entirely re-scanned and re-built tracks to update the iRacing 2026 landscape: Road America, Mid-Ohio Sports Car Course, and The Milwaukee Mile. Each of these tracks fully replace the older versions and are top-notch racing locations.

Both Summit Point Raceway and Road Atlanta have also received a major artwork update, taking their appearance into the modern age.

Finally, we plan to introduce a new system that more authentically replicates real-world multiclass race starts: dedicated pace cars for each car class. Please note that this feature must pass a final shakedown in Week 13’s iTested series before officially joining the IMSA iRacing Series.

Our physics processing engine has been upgraded to allow for multi-threading, making object interactions more accurate than ever before. Car Rule Sets have been made available on dozens more vehicles, providing even more structure and options to the ways you can race.

Our vehicle development team has completed a significant vehicle mechanics overhaul for both the Global Mazda MX-5 Cup and the Sprint Car – these cars should feel nearly brand new, and drive much closer to their real-life counterparts.

The iRacing Simulation has been updated from stem to stern for complete UTF8 character support – this includes chat messages, display names, and all files associated with iRacing such as Replays, Setups, and Camera sets filenames.

A new UI element has been added: Reference Car UI, which allows you to see live controls inputs from a reference car in solo sessions so you can learn and advance your own technique.

TWO brand new UI Widgets are now available: Pit Summary, which provides control and visibility to everything related to a pit stop, and Car Damage for a select few cars, which displays the general health of your vehicle.

The F9 Black Box has been reimagined as a Quick Access panel to add easy use for a variety of impactful options. A new UI Mode is also now available: “Minimal”, where you can strip down your interface to only the essentials and anything else you’d like to keep pinned.

Following up from last Season, the Fuel Calculator Widget algorithms have received more data and have improved estimates. The Track Map Widget has also been updated with some quality improvements for ease of use.

The iRacing Launcher Team has completed a full rebuild of the Team Registration process, making it easier than ever to clearly see how your team is registered for an event, and what everyone is signed-up for.

The Leagues area has been refreshed, leaving runway for upcoming improvements. Past Results may now be viewed as individual pages.

When launching a solo session from an Official Session, you may now also carry in the BoP from the event to your test session, allowing you to practice better.

The team also completed a re-build of the iRacing Companion App recently which will allow for even better future development – if you haven’t gotten the latest updates for it yet, be sure to grab them from your device’s preferred app store!

Finally, AI racing has been expanded to EIGHT new cars, including Aston Martin Valkyrie AMR-LMH, Caterham – Academy and 420R, Gen 4 Grand National, Chevrolet Corvette C7 Daytona Prototype, Formula Renault 2.0, [Legacy] BMW Z4 GT3, and [Legacy] Riley MkXX Daytona Prototype – 2008.

AI racing is also now available at NINETEEN new track configs, including Auto Club Speedway – Competition, Interior, and Moto, Federated Auto Parts Raceway at I-55, Kansas Speedway – Infield Road Course and Road Course, Mid-Ohio Sports Car Course – All configs, Oswego Speedway – Dirt, Road America – All configs, The Milwaukee Mile – Both configs, and USA International Speedway – Dirt.

Rain racing availability comes pre-loaded with the new Aston Martin Valkyrie AMR-LMH and both Caterhams as well as all non-Oval new track configs.

Road Course Start Zone Procedure

When Start Zones are selected for an active session, participants will be shown the pace speed throughout the rolling grid pre-race pace lap.

The pace value is displayed in grey so drivers know the exact speed of the pace car. Cars should be formed into an orderly grid and maintain pace speed as they approach pit entry.

After the pace car enters pit lane, the pace speed changes from grey to yellow. Once yellow, Race Control pace-speed enforcement is active.

Any attempt to jump the start by accelerating early will receive a jumped-start penalty. All rows must maintain pace speed until Barney, Legendary Flagman, drops the green flag.

• The message for failing to meet driver change requirements has been updated.
• Fixed an issue where cars with higher car numbers could be delayed when entering Qualifying.

Pit Stops

A variety of pit-stop procedures have been updated to more accurately represent the number of available wheel guns, tire change times and jacking procedures. Individual vehicle and class notes provide additional details.

Graphics
