ETS2 update 1.58: how physics and collisions changed

Euro Truck Simulator 2 update 1.58 revised how trucks accelerate, coast, lean and respond at low speed. SCS Software previewed the physics work on January 25, 2026, tested it in the public beta and shipped the stable update on February 12.

Throttle and engine behaviour

A new throttle torque map made pedal input less binary and gave the engine more natural resistance when the driver lifted off. The simulation also gained revised turbo audio, a short rise in revs before the engine starts and a hill-start assistant. Together, the changes targeted more predictable low-speed control without removing the weight of a loaded truck.

Suspension geometry

Version 1.58 added more detailed camber and caster behaviour to the suspension model. The goal was to improve how the vehicle settles, steers and transfers weight. Results still depend on the truck, chassis, load, controller and gameplay settings, so the update should not be read as one identical handling preset for every combination.

An optional keyboard throttle shortcut

Keyboard players could enable a double-tap throttle option. Holding the key applied partial acceleration; tapping twice requested full throttle. The setting was disabled by default, letting players keep the old digital control unless they deliberately chose the more graduated input.

What changed around collisions

SCS also worked on road collision geometry to reduce the sawtooth effect that could make a vehicle behave harshly along some curved road segments. The original joint announcement discussed ETS2 and American Truck Simulator together, with some road-specific examples belonging to ATS. For ETS2, the supported claim is the shared collision-system improvement, not every example shown for the American map.

From preview to stable release

The January article described work still entering testing. The February stable notes are the better reference for what reached the public branch, while later hotfixes may have refined the behaviour further. Mods that alter physics can also mask or replace the stock changes.
