High (core gameplay) 2. Core Physics & Vehicle Parameters | Parameter | Description | |-----------|-------------| | enginePowerCurve | Torque vs RPM (from idle to redline) | | transmission | Automatic or manual with realistic gear ratios | | finalDriveRatio | Differential ratio | | vehicleMass | Affects acceleration, braking, inertia | | dragCoefficient | Air resistance increasing with speed | | rollingResistance | Constant deceleration at low speeds | | wheelRadius | For rotational speed and ground contact | | suspensionStiffness | Weight transfer and body roll | | tireGripCurve | Grip vs slip angle (peak grip then drop-off) |

It focuses on behavior, physics feel, constraints, and AI if applicable. 1. Overview Summary A modular driving controller that simulates realistic car movement including engine torque, gear shifting, tire friction, suspension weight transfer, and fuel consumption. Works for player input or AI-controlled vehicles.
