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)
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.
Get behind the wheel and experience American Truck Simulator with the most realistic physics yet
