MotorSim 2

MotorSim 2 is a powerful performance calculator designed for land vehicles. This app provides a physics-based simulation of straight-line acceleration, not a driving game. It allows you to meticulously configure technical vehicle characteristics and instantly see the resulting performance.

The interactive simulator features a speedometer, RPM meter, throttle, brake, and gear shifting (manual or automatic). It even includes a procedurally generated engine sound, offering a realistic experience without relying on sampled audio. Vehicle position is displayed along a simulated 1/4 mile track. Saved "ghost" runs allow for easy comparison of different vehicle setups.

Configurable Vehicle Parameters:

• Maximum Power
• Power Curve (point-by-point definition)
• Torque Curve (power curve automatically defines torque)
• Maximum Engine RPM (ignition cutoff)
• Gear Configuration (up to 10 gears)
• Resistances (Cd, frontal area, 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, etc.)
• Numerous other parameters measurable via the interactive simulator.
