Download Physics Mod V1.3 American Truck Simulator

Suspension & Cabin Movement

• Chassis Suspension Overhaul – More realistic weight transfer and rebound behavior.
• Cabin Suspension Adjustments – Improved independent cabin movement that reacts naturally to road conditions.
• Balanced Cabin Lean & Roll – No more “blocky” side-to-side motion; smoother transitions.
• Reduced Over-Dampening – Trucks now feel less stiff and more responsive to bumps and terrain.
• Transmission, Gearbox Behavior & Powertrain Realism
• Improved Automatic Shifting Logic
• Shifts at lower RPMs under light throttle for better fuel efficiency.
• Holds gears properly under load for realistic power delivery.
• Reduced excessive gear hunting.
• Adjusted shift timing for a more natural feel.
• Refined Manual Gearbox Behavior
• Clutch engagement tuned for smoother starts.
• More realistic RPM fall.
• Improved Transmission Resistance – More natural power loss through the drivetrain, making acceleration and deceleration feel smoother and more authentic.
• Balanced Flywheel Inertia – The engine now holds and loses revs in a more progressive and realistic way, improving shift behavior and coasting.
• Refined Torque Converter Behavior – Gear shifts feel smoother and more natural, especially under load, preventing excessive slipping while maintaining realistic power delivery.

Steering & Handling

• More Progressive Steering Response – Less sensitive at center for better highway stability.
• Balanced Steering Wheel Travel – Adjusted max steering angle to better match real trucks (38 degrees)
• Supports Gamepads – Features realistic, speed-sensitive auto-centering for smooth and precise control.

Road & Environment Interaction

• Refined Wheel Slip Behavior – Adjusted slip factors to reduce understeer/oversteer.
• More Noticeable Mini-Bumps & Road Feedback – Feels more like a real truck suspension.
• Subtle Air Seat Movement Simulation – Adds immersion with natural seat bounce over bumps.

Realistic Throttle Curve
Optional realistic throttle curve included, providing smoother and more progressive throttle response. This improves low-speed control, reduces jerky acceleration, and enhances realism by mimicking the way real truck engines respond to throttle input.

Compatibility & Optimization
Works with All Trucks – Fully compatible with stock and modded trucks (providing they have independent chassis/cabin physics)

• Designed for Wheel Users – Balanced for users with a steering wheel.
• Designed for Gamepad Users – Handle your truck with ease without a steering wheel.
