iRacing’s latest build was released on the 10th of June 2025, and it introduced several pieces of new content to the sim. With only a couple of cars and one track made available, the headline features of Season 3 were behind the scenes, with an overhaul of iRacing’s GT3 car physics perhaps the most important handling tweak in the sim’s recent history. iRacing also received many other minor adjustments, including the second part of its NASCAR Refresh project, an update to its Paint Shop and a host of other physics and visual tweaks. Check out all the new content and features in iRacing’s 2025 Season 3 Update below.
