The iRacing 2026 Season 2 Patch 2 update is live. Build 2026.04.06.02 released April 6 and covers physics, AI, UI, cars, and tracks.
Balance of Performance Gets Expanded Range
The biggest change in iRacing 2026 Season 2 Patch 2 is to Balance of Performance. iRacing now allows Engine Power Adjustment above 100%. Series operators can increase engine output, not just cut it. The new range runs from 90% to 110% of original engine power. The Vehicle Weight Adjustment also expands. iRacing now allows negative values, reducing a car’s weight by up to 50Kg below stock. The full weight range is minus 50Kg to plus 250Kg. Both settings apply to official series, hosted sessions, and test sessions.
AI, Telemetry UI, and Bug Fixes
iRacing fixed an AI qualifying issue. AI drivers failed to post times if you advanced the session too quickly. That is corrected. iRacing also fixed AI lap counting when you quit mid-race. AI opening lap performance improves globally. AI at The Milwaukee Mile gets an extra pass. The throttle and brake widget gains two new options. Graph playback now supports 30 seconds. A horizontal line overlay helps you read values more clearly. iRacing also fixed a crash-to-desktop when setting a HUD profile as the global default.
Car and Track Updates
iRacing removes incorrect power scaling from TCR cars at Nurburgring Nordschleife. iRacing corrects a Meatball Flag bug on the Audi 90 GTO and Nissan GTP ZXT. The flag triggered on bodywork-only damage. Street Stocks and the Dirt Street Stock get stronger roofs. iRacing fixes a female driver animation on the Honda Civic Type R TCR for paddle shifts. The Supercars Ford Mustang Gen 3 now shows tail lights in rain. The BMW M4 GT4 rear hull stiffens. The Super Late Model nose gets improved damage limits.
Track changes are visual. Nurburgring loses purple surface tinting. Sebring gets better draw distances on flags and bridges. St. Petersburg updates banners and fixes specular textures. Mount Panorama fixes a garage that disappeared at certain render settings. The complete notes are on the iRacing forums.
