MotorSim 2

MotorSim 2 is a powerful performance calculator for land vehicles, offering a detailed physical simulation of straight-line acceleration. This isn't a driving game; it's a sophisticated tool for analyzing vehicle performance based on configurable parameters.

MotorSim 2 lets you meticulously define technical characteristics and instantly see the resulting performance. An interactive simulator provides real-time feedback via a speedometer, RPM meter, throttle, brake, and gear shift (manual or automatic). The app even features procedurally generated engine sounds, not just samples, and displays vehicle position on a 1/4 mile track. Saved "ghost" runs allow for easy comparison of different configurations.

Configurable Vehicle Parameters:

• Maximum Power
• Power Curve (point-by-point definition)
• Torque Curve (automatically calculated from the power curve)
• 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.)
• Many other parameters measurable via the interactive simulator.
