MotorSim 2

MotorSim 2 is a powerful performance calculator designed for land vehicles. This app is a physics simulator, not a driving game; it focuses solely on simulating straight-line acceleration performance.

MotorSim 2 lets you meticulously configure a vehicle's technical specifications and then calculates the resulting performance characteristics. It features an interactive simulator complete with speedometer, RPM meter, throttle, brake, and gear shifting (manual or automatic). The app also generates a procedurally created engine sound (not from samples) and visually displays the vehicle's progress along a 1/4 mile track. After testing a configuration, users can save a ghost/shadow lap for later comparison with other settings.

Configurable Vehicle Parameters:

• Maximum Power
• Power Curve (defined point-by-point)
• Torque Curve (power curve automatically defines torque)
• Maximum Engine RPM (ignition cutoff)
• Gear Configuration (up to 10 gears)
• Resistances (Cd, frontal area, and rolling resistance coefficients)
• Vehicle Weight
• Tire Size
• Shift Time
• Transmission Efficiency

Calculated Performance Parameters:

• Maximum Speed
• Acceleration times (0-60, 0-100, 0-200, 0-300 km/h, etc.)
• Many other performance metrics measurable via the interactive simulator.
