With the mod installed, a Scania or Volvo truck could accelerate from 0 to 300 km/h faster than a modern supercar, completely shifting the game from a simulator into an arcade racer. The "Patched" Rumor: What Actually Happened?
If you cannot find a "patched" version, downgrade your game via Steam Betas to version 1.42. The legendary "HGDP 400km/h+" mod still works perfectly on that build. Sometimes, the past is where the true speed lives.
that increases tire grip, stiffens suspension, and adjusts the center of gravity to keep the vehicle grounded. Why High-Speed Mods "Patch" or Break
However, patched versions do exist. The most reliable current method is not a single mod, but a : euro truck simulator 2 speed mod 400 km h patched
To push a truck toward the 400 km/h mark in current versions of ETS2, you must address three distinct layers of speed limitation: Disable In-Game Limiter: Options > Gameplay menu, uncheck the Truck Speed Limiter
Adjusted the suspension so the truck doesn't launch into orbit the moment you hit a slight bump at 300 km/h.
, which often include specialized gearboxes with longer final drive ratios necessary for extreme top speeds. Physics & Stability With the mod installed, a Scania or Volvo
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.
The ETS2 community is split. Purists call the 400 km/h mod “an abomination that ruins the spirit of simulation.” But the upvotes and downloads tell a different story:
However, recent game updates have altered how physics and engine modifications interact, leading to widespread reports that the classic 400 km/h mod has been or broken. The legendary "HGDP 400km/h+" mod still works perfectly
When a 400 km/h mod is successfully patched and running, the experience is a surreal blend of technical mastery and absolute absurdity. The physics engine, never intended to handle such velocities, behaves unpredictably. A slight turn of the steering wheel at 300 km/h can result in an immediate, physics-defying flip. The scenery blurs into a smudge of green and grey, and the GPS struggles to recalculate routes fast enough to keep up. It transforms a simulation game into a high-octane arcade racer. For many players, this is the ultimate test of skill—a way to prove their reflexes are sharp enough to handle the unhandleable.
While the base game allows you to disable the 90 km/h governor in the settings, physics still dictates your top speed. Even the most powerful Scania or Volvo engines usually top out around 160–170 km/h before air resistance and gear ratios win the battle.
SCS Software adjusted how air resistance scales at high speeds. The drag coefficient now increases exponentially, meaning a standard modded engine can no longer generate enough force to push past the aerodynamic wall.
