Avoid winding routes like the UK or Alpine passes. Utilize the long, flat, straight highways of the Going East or Germany map overhauls to safely reach terminal velocity.
Disclaimer: Using mods can sometimes cause game instability. Always back up your profile before installing new mods.
: If you are hosting a server, you must modify the server_config.sii file to set the speed limiter to "0" (disabled) to allow all players to reach full speed.
To safely install an updated, unpatched speed mod, follow these steps:
If you find your speed mod is no longer working, the "patch" is usually just a file structure change. You can often restore high-speed capabilities using these methods:
The addition of official Convoy multiplayer forced SCS Software to implement strict anti-cheat and file-verification protocols. If a player using a 400 KM/H mod joined a vanilla lobby, it caused severe desynchronization (rubber-banding) for everyone else on the server, ruining the multiplayer experience. The Current State of Speed Modding in ETS2 euro truck simulator 2 speed mod 400 km h patched
If you want to get your truck up to extreme speeds, let me know: What of ETS2 are you running?
The highways of ETS2 were designed for double-digit speeds. Sharp highway interchanges, toll booths, and AI traffic become lethal obstacles when approached at Mach 0.3.
At 400, the world compressed. Roadside trees streamed like code; headlamps were pinpricks. The trailer's sway tuned itself to a wavelength of nerves and software: tiny oscillations that the driver and the mod chased into harmony. For a breathless minute he existed only as a line on a map and a sound in a machine. He felt an odd gratitude for the audacity of strangers who wrote patches in cramped apartments and the engineers who had never intended a Euro rig to sing like that.
Recent versions of ETS2 introduced revamped suspension physics, realistic cabin movements, and fifth-wheel simulation. These systems calculate real-time mass distribution. When a truck exceeds roughly 180 km/h under these new rules, the physics engine experiences severe calculation errors, causing the truck to violently shake, clip through the road, or launch into the sky.
Before installing any mod, ensure the game's built-in restrictions are entirely removed. Navigate to > Gameplay . Scroll down to Truck Settings . Uncheck the box for Truck Speed Limiter . 2. The Modern 400 km/h Mod Architecture Avoid winding routes like the UK or Alpine passes
limiter, modern "400 km/h patched" versions offer a complete overhaul: Increases horsepower to over or higher.
In the world of ETS2 modding, "Patched" is a crucial keyword. Every time SCS Software updates the game (moving from version 1.50 to 1.51, for example), the internal code for physics and engine data often changes. This typically "breaks" older speed mods, leading to game crashes or trucks that simply won't move.
Euro Truck Simulator 2 (ETS2) is primarily designed as a simulation game that emphasizes realism and adherence to European road regulations. However, the game offers several ways for players to customize their experience regarding vehicle speed. Adjusting Speed in Game Settings
While SCS Software continues to patch exploits to preserve the simulation integrity of Euro Truck Simulator 2, the modding community consistently finds workarounds. By targeting the physics files alongside engine power, hitting 400 km/h remains entirely possible.
Altered the 12-gear and 14-gear gearboxes so the final drive ratio could sustain high velocities without hitting the RPM redline. Always back up your profile before installing new mods
The 400 km/h mod caters to the latter demographic. It removes the artificial speed limiter (usually capped at 90 km/h in Europe) and adjusts the engine definitions to allow for hypersonic velocities. The appeal is not necessarily about efficiency; in fact, completing a job at 400 km/h is often impossible due to the game's economy. The appeal lies in the absurdity. It is about taking a 40-ton Scania or Volvo and turning it into a land-based rocket ship. It transforms the game into a test of reflexes, a chaotic arcade experience where the laws of physics are mere suggestions, and the journey becomes a high-speed blur of motion blur and graphical pop-in.
Standard 12-speed transmissions will redline long before hitting 400 km/h. A patched speed mod requires a custom 6-speed or 18-speed gearbox with an extremely low final drive ratio (e.g., differential_ratio: 1.5 or lower) and overdrive gear ratios below 0.50 .

While SCS Software continues to update Euro Truck Simulator 2 to make it more realistic, the modding community will always find a way to break the rules. The 400 km/h speed mod isn't truly patched; it just evolves with every update.
