A land vehicle performance calculator.
MotorSim 2 is a performance calculator for land vehicles. Please note that this application is not a driving game; it exclusively performs a physical simulation of vehicle acceleration in a straight line.
MotorSim 2 enables you to configure technical specifications and calculates the resulting performance. It features an interactive simulator with a speedometer, RPM meter, throttle, brake, and gear shift (manual or automatic). The simulator includes a procedurally generated engine sound (not sampled) and displays the vehicle's position along a 1/4 mile track. After testing a configuration, users can save a ghost/shadow to later compare its performance against others.
Configurable vehicle parameters include:
- Maximum Power
- Power curve (definable point by point)
- Torque curve (since power equals torque multiplied by RPM, defining the power curve automatically determines the torque curve)
- Maximum engine RPM (ignition cutoff)
- Gears configuration (up to 10 gears)
- Resistances (drag coefficient, frontal area, and rolling resistance coefficients)
- Vehicle weight
- Tire size
- Shift time
- Transmission efficiency
Calculated performance parameters include:
- Top speed
- Acceleration times: 0-60, 0-100, 0-200, 0-300, and so on
- ... and any other metrics measurable using the interactive simulator.
