Truck Parts: These mods introduce "Ultimate" engines (often with 10,000+ HP) and custom gearboxes with extremely high gear ratios to allow for sustained acceleration past standard limits. This report outlines the status, mechanics, and limitations

However, the functionality of these mods is heavily dependent on the game's version. The term "patched" in this context can have two meanings: either the mod itself has been patched to work, or the game has been patched to break it. SCS Software, the developers of ETS2, frequently updates the game engine. Major updates, such as the transition to newer DirectX versions or the introduction of new map sectors, often alter the file structure that mods rely upon. When SCS patches the game, a 400 km/h mod designed for version 1.40 might render the game unplayable in version 1.50, causing crashes or simply failing to load. This forces the modding community to constantly "patch" their creations, updating the definitions and physics sets to remain compatible with the latest software.
