Promods, RusMap, and other expansion mods use custom road surfaces and physics boundaries. The 400 km/h mod often needs “patching” to prevent your truck from falling through Scandinavia’s frozen lakes when braking at 380 km/h.
Thus, when you see “patched” in the mod title, it means “This version works with the latest ETS2 update and known map mods.” Unpatched versions will crash your game or cause the “infinite rev” bug.

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:
“I laughed so hard I cried. My Volvo took off from a ramp outside Calais and I flew over the Channel. Hit 412 km/h before the game crashed. 10/10.” – TruckerMike88 Promods, RusMap, and other expansion mods use custom
“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.” – MapTestEU
“Stop asking for multiplayer support. You’ll ruin TruckersMP. Keep this madness in single-player.” – Dev_Reece (moderator) “I laughed so hard I cried
The “400 km/h speed mod” is not centrally patched by SCS, but individual mods become outdated after game updates. Fully working versions still exist for recent ETS2 patches (e.g., 1.50), though the game engine handles such speeds poorly. If you’ve tried a specific mod that stopped working, check for an update on Steam Workshop or the original download page—otherwise, consider 250–300 km/h mods for a less broken experience.
