OpenRoad: Hyper Power is an extreme performance overhaul that replaces the engine, gearbox and physics behavior for every truck in American Truck Simulator. It dramatically increases torque, speed potential and grip, turning ordinary rigs into hyper-powered machines capable of extreme top speeds.
The mod multiplies engine torque by 12 and adjusts the final drive ratio so top speeds can reach roughly 540 to 640 km/h depending on gearbox length. Air resistance is cut down for less drag, tyre grip is boosted by 30 percent, and braking power is quadrupled with much faster cooldown times. It also folds in fuel and rollover adjustments from other OpenRoad add-ons, so drivers get a complete extreme-physics package in one mod.
This mod is meant for players who already enjoy the OpenRoad series and want the most intense version of the power overhaul. It is not compatible with other mods that alter vehicle physics or engine/transmission files, and it works only in single-player mode, not on multiplayer servers.
