The iRacing 2026 Season 1 Release Build is out of the paddock and on the starting grid! This is one of four major annual releases for iRacing, and adds new content, features, upgrades, and a toolbox-full of fixes for 2026 Season 1, which officially starts on December 16th at 0000 UTC!

We have wasted no time in advancing our new Sim UI towards the next level of awesome and have added several new features for this release, including: Options Search, four Black Box pages have been repackaged into standalone Widgets, and substantial UI customization is now available via the new Widget Editor feature! Standalone Widgets are read-only UI elements you may place anywhere on your screen to monitor important data, including: Lap Timing, Relative, Standings, and Weather. Options Search will let you short-cut navigation and control of all of your iRacing Options. Additionally, with Widget Editor, nearly all UI elements can now have customized size, position, and transparency.

The iRacing stable expands with two new bays for two brand-new cars: the FIA Cross Car and the Porsche 911 Cup (992.2)! We have updated the aerodynamics model for the NASCAR Trucks using additional real-world data to keep the simulation authentic. The Dallara IR18 has completed an ongoing Hybrid System update, and the art team has refreshed the car to match. The Toyota GR86 has also had a bumper to bumper physics and systems update based on the latest real-world data. The GT3 Class Cars also demanded another suite of updates continuing from last season to really optimize that racing experience.

iRacing’s newest track offerings bloom in South Australia, with Adelaide Street Circuit, and in Florida with Miami International Autodrome! To go along with our brand new FREE Dirt Road car, we had to add two New Dirt Road Configs: Lucas Oil Speedway – Off Road and Winton Motor Raceway – Rallycross! Rockingham Speedway – Oval has been remodeled to the modern age with new laser scan data, while the historic 2012 track remains preserved for continued use. Mount Panorama has received a comprehensive art upgrade.

Our simulation engineers have worked hard this season to optimize the initial parameters and properties tracks start their existence within the Sim, including water, puddles, and wetness, and dust, debris, and driving lines. The Oval Refresh project returns with advancements to rubber density and distribution, thermal flow, and ultimately improve lane dynamics and multi-groove racing. And finally, new languages have been added to the non-in-Sim iRacing application, including: French, German, Italian, Portuguese (European), and Portuguese (Brazilian)!

Grab your raincoat, as the Porsche 911 Cup (992.2) is ready for rain racing. AI Drivers have also been fully programmed to race for the gold with the Porsche 911 Cup (992.2). AI Drivers have already mastered all of the new pavement tracks (Adelaide Street Circuit and Miami International Autodrome), and also notched Rockingham Speedway – Oval in their belts with their spare time.

————————————————————

Localization

• Customers may now select to use iRacing in several new languages, including:
  • French
  • German
  • Italian
  • Portuguese (European)
  • Portuguese (Brazilian)
  • This translates much of the non-in-Sim iRacing application. For more information about what this includes, does not include, and if you are a native speaker, how you can help us improve our work here:
  • Localization

Paint Kit

• The following new partners have been added as available sponsors in the iRacing Paint Kit:
  • Direct Supply
  • Dude Wipes
  • GFX Wheels
  • Heat Wave Racing
  • Off Axis Paint
  • Rego-Fix

3rd Party /data API & /jforum Use

• As announced in last season’s release, the use of the legacy authentication endpoint /auth is being retired. If you are still consuming the /data API after using the /auth endpoint or interacting with the legacy /jforum endpoint, please see the following post for the changes you need to make to continue using the /data API.
  • Legacy Authentication Removal

iRacing Simulator

————————————————————

Licenses

• Fixed an issue where users were seeing improper contributions towards MPR.
  • The Sporting Code states that a Race should only be counted if the participant completes at least 50% of the number of laps (rounded down) as the winner in their car class. This was not being enforced. This change is not retroactive – there will be no changes to existing data within 2025 Season 4 or before. Enforcement of lap completion for MPR begins now with 2025 Season 4 Week 13.

Netcode

• The netcode for handling vehicles and elevation changes has been updated to improve their vertical positioning in the world. This fixes an issue where some drivers could see other cars floating above the track or slightly buried beneath it at some tracks with high elevation changes, especially when those drivers had high latencies.
• Updated the rotational references and predictive calculations for opponent vehicles. Opponent vehicles should now orient in a more accurate direction based on where that driver is facing, their rotational speed, their steering inputs, and forces acting on their car.

Race Control

• During Dirt Road events, drivers will now correctly be disqualified from a Qualifying session if they use the joker route.
  • Any laps completed before employing the joker will still count, and the driver can still participate in subsequent Sessions, such as the Race.
• Tightened up the detection algorithm for course cuts to help reduce the likelihood that black flags will be given for course cuts that did not occur.

Dynamic Track Model

• During track initialization, for track usage percentage, the distribution of dust has been tuned for a more accurate dispersal. Also, fewer simulated off-track excursions will be present.
• As part of the Oval Refresh project, tire sliding parameters have been adjusted to apportion more rubber tearing from the tire than the track as a track rubbers in. This will result in more tire wear on rubbered-in tracks, reducing the long-term advantage of staying in the groove.
• The tire versus track wear apportioning for AI vehicles has been tuned. This increases the wear and rubbering-in, especially at moderate track rubber levels.
• Fixed a recent problem with deep initial water depths, which resulted in “growing puddles” when cars interacted with the track.

Physics

• Damping rates for detached vehicle parts have been improved. This should stop detached parts from jittering and jumping unrealistically.

AI Racing

• AI Drivers have been fully trained to race with the following new vehicles:
  • Porsche 911 Cup (992.2)
• AI Drivers have been fully trained to race at the following new track configurations:
  • Adelaide Street Circuit
  • Miami International Autodrome (ALL 5 Configs!)
  • Rockingham Speedway – (Oval)
• AI drivers have expanded their minds, and are now capable of making more independent decisions about their positioning during pacing on the race line and how it relates to the cars around them. AI Drivers should now appear to take their own unique paths, while maintaining a general focus on an ideal pace line.
• After a light course-load over the Summer, the AI School for the Gifted was back in full swing this Autumn. AI course materials for the latest semester included the following:
  • [Garage Course Level IV] Hybrid Vehicle Systems
  • How & When to Send It: 1001 Scenarios for Parcels & Race Rejoins

  • Ligier JS P320
  • Mercedes-AMG W12 E Performance
  • Mercedes-AMG W13 E Performance
• The AI opponent paint scheme database has been fully rebuilt with more realistic paint schemes for all vehicles on the Sim.

    • Lap Timing (F1)
    • Relative (F2)
    • Standings (F3)
    • Weather (F11)
  • Unlike Black Boxes, you can have multiple Standalone Widgets open at the same time.
  • These Widgets are read-only – you cannot interact with the data they display directly. But, if the data is adjusted or changed elsewhere, for example, in a Black Box, the change will be immediately reflected by the standalone Widget.
  • To enable Standalone Widgets, enter the UI editing mode by pressing Alt-K, scroll down to the Standalone Widgets section, and click the eyeball to toggle their visibility.
• The “Search” feature has been added to the Options menu!
  • Start typing any option or parameter of an option, and the menu will automatically filter to only show items related to your search string. You can then edit any option displayed in the Search results as desired.
• GENERAL UPDATES & FIXES:

Tracks

————————————————————

Adelaide Street Circuit

• NEW TRACK!
• A new Road track, Adelaide Street Circuit, is now available for purchase and racing!
  • Australia is known the world over for some of the most exciting street circuits in auto racing, and Adelaide, the capital city of South Australia, boasts one of the finest. Its first event, part of the 1985 World Driver’s Championship, earned the Race Promoters’ Trophy as the best-promoted event of the season, and its last event in that championship set an attendance record with 210,000 people. Racing through the streets of Adelaide returned in 1999 thanks to Supercars, and the event has been a staple of that calendar ever since. The modern Adelaide layout clocks in at an even two miles (3.219 km), with 14 turns. The lap begins with the complex Senna Chicane, which produces some of the most compelling photography in motorsport as Supercars can quite literally fly through the kerbing. Lengthy straightaways on the back half of the lap lead into the Dequetteville Hairpin, Victoria Park section, and finally the Mistral Hairpin that sets drivers up for a charge to the finish line.

Big jumps, challenging whoop sections, and even an over-under bridge make this one of the most memorable circuits most drivers will see. After an extended period of inactivity, the off-road track returned to the national calendar in 2025 as the season opener.
  • All drivers who already have access to Lucas Oil Speedway now have access to this new track config!

Miami International Autodrome

• NEW TRACK!
• A new Road track, Miami International Autodrome, is now available for purchase and racing!
• This track includes five configs: Grand Prix, Marina Loop, MIA Loop, Extended MIA Loop, and Extended Marina Loop.
  • The city of Miami has a long and storied history of embracing open-wheel and sports car racing across numerous venues, both temporary and permanent. In 2022, that history finally culminated in a spot in the Driver’s World Championship, as the inaugural Miami Grand Prix joined the calendar that May on a multi-year deal to compete at the Miami International Autodrome, with support from the Porsche Sprint Challenge North America and W Series. The 3.363-mile, 19-turn temporary circuit has been designed to run through parking lots around Hard Rock Stadium, home of the NFL’s Miami Dolphins, without using any public roads. Unlike many other modern FIA Grade 1 circuit designs, its longest straightaway isn’t the start-finish and pit straight, but rather the stretch between turns 16 and 17 on the full layout. After the initial success of the Miami Grand Prix, multiple shorter layouts were constructed to give the circuit year-round viability in use for smaller series and private events.
