The standard ETS2 tops out around 150-160 km/h (93-100 mph) even with the limiter disabled, due to engine torque curves, drag coefficients, and transmission gearing hardcoded into the game’s physics engine. The is a set of edited game files (usually a custom engine.sii and chassis.sii ) that overhauls:

Raindrops hammered the asphalt like impatient fingers as Leo flicked the wipers and felt the rumble through the seat. The dashboard glow of his virtual rig was a promise and a dare: the new speed mod—patched, whispered about across dusty forums—sat installed, tuned to the impossible number that made seasoned drivers scoff and kids grin: 400 km/h.

A ensures the mod is compatible with the latest engine updates, meaning the engine files are properly mapped to the newer game structure, preventing performance issues or crashes. How to Install the 400 km/h Speed Mod

By default, ETS2 enforces a strict speed limiter to reflect real-world European trucking laws. To exceed this without mods, you can manually disable the "Truck Speed Limiter" in the menu. However, even with this off, standard truck engines and gearboxes aren't designed to reach extreme speeds like 400 km/h. How the 400 km/h Speed Mod Works

This is an advanced technique that requires some technical skill, but it gives you total control and a mod that won't be "patched" by standard updates.

Later updates tied tire grip directly to the weight of the cargo and weather conditions. Modifying a text file was no longer enough to keep a truck stable. At 400 km/h, the physics engine calculated that the tires had zero traction, causing the truck to spin out instantly, regardless of the horsepower configuration. 3. Structural File Changes

The community's reaction to these hyper-speed mods is mixed but fascinating.

Each patch is a fresh set of band-aids. There will never be a fully stable 400 km/h mod because the underlying game code would need a rewrite.

“Used the patched version to test a map mod’s boundaries. Found a hole near Bern at 380 km/h. Fell into the void for 3 minutes. Totally worth it.” –
