iRacing launches 2026 Season 1 with three new circuits, comprehensive vehicle physics updates, and significant user interface improvements. The development team has expanded to four times its 2020 size, enabling simultaneous work across expanded initiatives.[1][2]
New Circuits Launching in Season 1 2026
iRacing debuts three major tracks in Season 1, expanding circuit variety and geographic representation significantly.
Adelaide Street Circuit: Australian Street Racing Debut
Adelaide Street Circuit, 3.195 km, hosted Formula One starting 1985 and remains central to Supercars racing. The track features the Brabham Straight exceeding 200 mph, the Senna Chicane requiring three consecutive precision turns, and Turn 8 at sustained 130 mph with limited runoff. Bumpy asphalt surfaces create variable grip conditions throughout the lap.[2][3][1]
Miami International Autodrome: Five Configuration Options
Miami International Autodrome wraps around Hard Rock Stadium, home of the NFL’s Miami Dolphins. The 5.41 km venue offers five distinct configurations: Grand Prix, Sprint, Club, series-specific, and test variants. iRacing collaborated directly with track management on data capture and configuration testing.[4][1][2]
Lucas Oil Speedway Off Road: Dirt Racing Expansion
Lucas Oil Speedway Off Road mirrors real-world facilities hosting UTV and Pro Truck competition. Existing dirt oval owners receive this track free; new customers get both tracks in one package.[1]
Vehicle Updates and Physics Refinements
Porsche 911 Cup 992.2: Replaces 992.1 Across All Series
The Porsche 911 Cup 992.2 generates approximately 520 horsepower, a 10 hp increase from 992.1’s 510 horsepower. Real-world performance gains reach 1–1.5 seconds per lap on grand prix circuits. Updated dry and wet tire specifications were developed with real-world drivers. Current 992.1 owners receive the 992.2 free; 992.1 transitions to legacy status.[5][6][1]
Multi-Platform Physics Improvements
Key vehicle updates include: GR86 center of gravity adjustment preventing rollover, increased anti-roll bar sizes matching series specifications, revised rear alignment settings, expanded spring rate ranges, driveline parameter adjustments, and engine torque curve refinements. NASCAR Trucks receive aerodynamic refinement using new CFD data based on competition-common body configurations. GT3 class receives spring perch auto-adjustment, Mercedes direct ride height adjustment, Acura rear wing aero revision, BMW engine model update, and Corvette tire warm-up improvements.[1]
FIA Cross Car: Accessible Dirt Road Entry Point
The FIA Cross Car provides accessible dirt road racing introduction emphasizing controlled sliding and aerial stability. Free to all iRacing members, it debuts in dedicated FIA Cross Car Fixed series on existing free RX tracks.[1]
User Interface and Network Enhancements
Sim UI improvements include dynamic search functionality for Options menu, Widget Editor for customization, standalone black boxes for Lap Timing, Standings, Relative, and Weather information. Network improvements feature Quality Flag removing poor connections and netcode refinements addressing vertical popping and lateral extrapolation issues. Weather system recalibration improves rain prediction accuracy.[1]
| Feature | Status | Timing |
|---|---|---|
| Mount Panorama visual refresh | Likely Season 1 | Final testing pending |
| Oval Refresh Phase 2 | Borderline S1 or S2 | Testing dependent |
| Audio enhancements | Confirmed | Season 2 |
Commercial Releases and Development Infrastructure
NASCAR 25 achieved over 200,000 console units sold in October 2025’s first month. Steam release occurred November 11, 2025. iRacing Arcade launches Steam December 2, 2025, with console releases early 2026. INDYCAR: The Game is scheduled for 2026 release.[7][8][9][10][1]
Graphics engine vertical slice targets Q1 2026; full completion remains through 2026. Physics team expanded with recruitment from four separate racing simulation platforms. Audio architecture rearchitected to multi-threaded operation for Season 2 features including global reverb and cockpit reverb.[11][1]
