Tesla’s in-car visualizations for features like Autopilot and Full Self-Driving might be getting an upgrade with a switch to Epic Games’ Unreal Engine. As reported by Not a Tesla App, Tesla hacker greentheonly says they found evidence of the change in Tesla’s 2025.20 firmware for Tesla Model S and Model X cars with AMD chips.

Unreal Engine is perhaps best known as a development tool for video games, but Epic has been making a bigger push as of late for automakers to use Unreal Engine. Currently, Tesla uses the Godot engine for the visualizations, according to greentheonly, so if Tesla switches to Unreal Engine, it would join a growing number of automakers that use Epic’s engine inside its cars, including Rivian, Ford, GMC, Volvo, and Lotus.

Tesla and Epic Games didn’t immediately reply to a request for comment. This isn’t the first time the two companies have been connected to each other; Tesla’s Cybertruck was added to Fortnite last year.
