MotorSim 2

MotorSim 2 is a powerful performance calculator designed for land vehicles. This app provides a realistic physical simulation of straight-line acceleration, focusing on performance analysis rather than driving simulation. It allows users to meticulously configure vehicle specifications and instantly see the impact on performance.

MotorSim 2 features an interactive simulator complete with speedometer, tachometer, throttle, brake, and gear shifting (manual or automatic). The app generates a procedurally created engine sound, avoiding the use of sampled audio, and visually tracks vehicle position along a 1/4 mile track segment. Users can save performance runs ("ghosts") for later comparison and analysis.

Configurable Vehicle Parameters:

• Maximum Power
• Power Curve (point-by-point definition)
• Torque Curve (defined automatically from the power curve)
• Maximum Engine RPM (rev limiter)
• 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 mph, 0-100 km/h, 0-200 km/h, 0-300 km/h, etc.)
• Numerous other performance metrics measurable via the interactive simulator.
