Tesla appears to be preparing another round of interior upgrades for its vehicles, this time for the Model 3 Premium and Performance trims, after similar changes were recently introduced on the Model Y.
Backend references discovered in Tesla’s EU and China configurator assets by X user @Tesla_NL_TR point to the addition of a new trim code: IN3PB (Interior 3 Premium Black). This code is tied to an Alcantara-style black headliner and has already been mapped to 2026 Model 3 Performance and Premium VINs.
Tesla recently introduced a black headliner on the Model Y, replacing the lighter grey fabric used in previous builds. Bringing that same treatment to the Model 3 Performance and Premium trims makes sense, and follows Tesla’s regular pattern of slowly rolling out new features across its entire lineup.

Following that same trend, another upcoming addition is a new entry spotted in Tesla’s Electronic Parts Catalog (EPC): “Display_16_QHD,” which refers to the larger 16-inch QHD display that was also recently added to the Model Y. Multiple 2026 Model 3 builds associated with this component are marked with a green dot, suggesting the hardware is already in production or imminent.
At this point, none of these changes have been officially announced by Tesla. The references were discovered within EU and China configurator assets and backend systems, but they have not appeared in public ordering pages.
Based on previous experience, we could see 2026 Model 3 Premium and Performance builds shipping with these upgrades in the coming weeks.
