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![/p][p][/p][p]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.[/p][p][/p][p]The iRacing stable expands with two new bays for two brand-new cars: the FIA Cross Car and the Porsche 911 Cup (992.2)!

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.[/p][p][/p][p]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.[/p][p][/p][p]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)![/p][p][/p][p]Grab your raincoat, as the Porsche 911 Cup (992.2) is ready for rain racing.
