MotorSim 2

MotorSim 2 is a powerful performance calculator designed for land vehicles. This app is a physics simulator, focusing solely on straight-line acceleration; it's not a driving game. MotorSim 2 lets you meticulously define technical specifications and then calculates the resulting performance characteristics.

The interactive simulator features a speedometer, RPM meter, throttle, brake, and gear shifting (manual or automatic). It even includes procedurally generated engine sounds, not simply samples, and visually tracks vehicle position along a 1/4 mile track segment. After testing a configuration, users can save a ghost/shadow lap for later comparison with other vehicle setups.

Configurable Vehicle Parameters:

• Maximum Power
• Power Curve (point-by-point definition)
• Torque Curve (defined automatically from the power curve since power = torque * rpm)
• 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 0-60, 0-100, 0-200, 0-300 km/h (and beyond)
• Numerous other performance metrics measurable via the interactive simulator.
