NASCAR 25 Developer Diary Details Expanded Career Mode and Livery Editor

iRacing Studios has revealed new details regarding the career mode mechanics and livery editor upgrades in NASCAR 25 ahead of its September launch.

3 September 2026

iRacing Studios has released a new developer diary for the upcoming NASCAR 25 simulator, detailing significant updates to the game's career mode and customisation tools. Compared to earlier entries, players will have greater depth in strategic decision-making between race weekends.

The revamped career mode places a stronger emphasis on long-term planning. Progression requires managing resource allocation and selecting car upgrades, directly influencing performance over the course of a season. The mode also introduces coaching from 2010 Daytona 500 winner Jamie McMurray. Players will be able to review and compare their telemetry against reference data, examining throttle inputs, corner entry points, racing lines, and track-specific techniques.

The livery editor has also received major enhancements. The selection of base decal shapes has expanded from 7 to 50, alongside a new mirroring function that allows decals to be duplicated onto the opposite side of the car.

NASCAR 25 is scheduled for release on 18 September for PlayStation 5, Xbox Series X|S, and PC, with Gold Edition owners receiving three days of early access.
