Street circuits, dirt road toys, and long-teased content are lining up for iRacing’s December update. Below is a tight, practical preview based on items either confirmed for the 2026 Season 1 build or credible enough to be in the running. We’re skipping far-off projects and sticking to what’s most realistic for December.
What’s Confirmed for the 2026 Season 1 Build (December)
FIA Cross Car (Dirt Road)
The FIA-backed Cross Car is officially slated for the December build. Think approachable power, short-wheelbase agility, and door-to-door rallycross energy. iRacing has framed it as an easy on-ramp to the dirt-road ladder, so expect it to anchor new rookie/fixed series and show up in AI quickly.

Miami International Autodrome (F1)
Miami has been in open development all year and moved through prototype and polish phases with fresh data following this May’s Grand Prix infrastructure. Multiple dev updates point to December as the target. Expect a race-weekend visual pass (grandstands, hospitality, walls) rather than a “sterile” year-round campus; this one should feel alive.
➡️Miami International Autodrome Confirmed for December 2025 Build
Wheatland / Lucas Oil Off Road (Dirt Road)
This project finally escaped limbo and is now pointed at December. Look for multiple short-course layouts and a modern art pass on dirt surfaces and barrier packages. It should pair nicely with the FIA Cross Car and refresh the dirt-road playlist for 2026 S1.

Strong Likely Candidates (Reading the Tea Leaves)
Track Refresh(es)
Developers have said multiple refreshes are in flight for Season 1, Season 2, and beyond. The exact venues aren’t public, but the pattern suggests at least one notable refresh could make December. Historically, these drops include updated scan meshes where available, new crowds/props, and modern shaders/lighting.
Race Control & Quality-of-Life Tweaks
Work on multi-class starts and the choose rule has been called out as “advancing.” December is a natural landing zone for rulebook polish, incident-review edge cases, and session-flow improvements. Expect under-the-hood fixes even if patch notes keep it brief.
Career-Mode Foundations: AI Championships & Save for AI
Career Mode is still a multi-phase effort, but AI Championships (phase one) has been discussed all year as the stepping stone. December could bring visible wiring for structured single-player ladders and the Save/Resume for AI feature that’s been teased alongside it. If not the full mode, a first-look or partial rollout fits the moment.
Dirt AI
The team signaled “significant progress,” with production resources now involved. Dirt AI often ships incrementally by car/track set; a first public slice in December is plausible, especially with FIA Cross Car priming the pump.
Force-Feedback Calibration Tool (Early Iteration)
Physics and FFB work is ongoing. A calibration/consistency tool has been mentioned as an active project. Don’t expect sweeping tire-model overhauls yet, but a first pass of user-facing FFB setup help could appear in the UI.
High-Interest Items We’re Watching (More Likely After S1)
These are hot, but the smart money says not December unless iRacing springs a surprise:
- Adelaide Street Circuit – Fully scanned and “well underway,” but the scope is large. If it misses December, it becomes a prime candidate for early/mid-2026.
- Aston Martin program – Vantage GT3 EVO is in; broader Aston additions (GT4 updates, Valkyrie LMH/GTP chatter) feel like near-future rather than December locks.
- NASCAR Euro Series car + Circuit Ricardo Tormo – Announced; timing suggests a later 2026 drop or a spring tie-in.
- St. Petersburg Street Circuit – Confirmed scanned and in production; again more likely a 2026 feature drop.
- NASCAR Craftsman Truck: Ram 1500 (2026) – Real-world debut is next February. A March/Season 2 cadence fits iRacing’s usual homologation rhythm.
- San Diego Naval Base street course (NASCAR 2026) – iRacing aided design; a sim release will come, but not before the real layout is finalized.
- Future tire model (NTMv10), higher physics rate & new graphics engine (DX12) – Deep projects making steady progress. Expect incremental benefits, dev previews, and toolchain updates rather than a wholesale switch in December.
Practical Takeaways for Members
- Count on: FIA Cross Car, Miami Autodrome, and Wheatland/Lucas Oil Off Road.
- Plan for: At least one track refresh, plus rulebook/race-control clean-ups.
- Hope for: First-slice AI Championships, Save for AI, early Dirt AI, and an FFB calibration helper.
- Temper expectations: Big-ticket engines (new graphics, NTMv10) and big street circuits (Adelaide, St. Pete, San Diego) are more likely after S1.
