At 400 km/h, even the Autobahn’s longest straight sections (e.g., Calais–Duisburg road) become too short to maintain speed for more than 8–10 seconds. 8. Known Issues & Workarounds | Issue | Cause | Solution | |-------|-------|----------| | Truck flips on slight bumps | Suspension too soft | Increase /def/vehicle/truck/.../chassis.sii shock_absorber: 50000 | | Engine overheats instantly | Modded RPM exceeds cooling model | Add engine_brake_torque: 4000 | | No speed above 360 km/h | Air drag coefficient | In /def/vehicle/truck/.../chassis.sii , set air_resistance: 0.8 (default 3.0–5.0) | | AI traffic freezes | Game pathfinding breaks at >300 km/h | Use console: g_traffic 0 (disables AI) | 9. Conclusion A 400 km/h mod for ETS2 is entirely achievable by modifying engine torque curves, raising the RPM limit, changing differential ratios, and adjusting physics parameters. However, the game’s map scale and road design are fundamentally incompatible with such speeds. The mod is best used for testing, empty highway runs in a private session, or as a proof-of-concept for extreme vehicle modification in the SCS engine. Warning: Do not use on multiplayer (TruckersMP) – you will be banned for speed hacking. Always back up original .sii files.
