iRacing Season 2 Preview: Track Debuts, Car Overhauls, AI Advances, and a Massive UI Overhaul

iRacing’s February 2026 update previews Season 2 with major content: new and refreshed tracks (notably the Grand Prix of St. Petersburg and a rebuilt Barber Motorsports Park), expanded car lineup (NASCAR Cup Next Gen Camaro ZL1, NASCAR Ram Truck, Audi RS3 LMS Gen2 TCR) and a sweeping physics overhaul for TCR and GTE, plus historic content updates (IMSA Vintage, Lotus 49). AI gains include Simulated Race results and skip qualifying, while the Sim UI gets profiles, live telemetry, a driving-line toggle, and reference-car features. Also new Leagues tooling, updater improvements, and ongoing long-term work on audio, Dirt AI, Career Mode, Spark graphics engine, and multi-threaded physics. The update signals a busy Season 2 launch with short-term releases (Arcade March 3) and mid-year milestones (Summit June), all while expanding fairness via protests and a growing team (>210 staff).
