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. The app features an interactive simulator complete with a speedometer, tachometer, throttle, brake, and gear shifting (manual or automatic). It even includes procedurally generated engine sounds (not samples) and displays the vehicle's position on a 1/4 mile track segment. After testing a configuration, you can save a ghost/shadow lap for later comparison against other settings.

Configurable Vehicle Parameters:

• Maximum Power
• Power Curve (defined point-by-point)
• Torque Curve (power curve defines torque automatically 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)
• Many other performance metrics measurable via the interactive simulator.
