MotorSim 2

Land vehicle performance calculator.

MotorSim 2 is a performance calculator specifically designed for land vehicles. Please note that this application is not a driving game; it specializes in physically simulating vehicle performance during straight-line acceleration.

MotorSim 2 enables you to configure technical specifications and calculates the resulting performance metrics. It features an interactive simulator complete with a speedometer, RPM meter, throttle, brake, and gear shift (manual or automatic). The simulator includes procedurally generated engine sounds (not based on sampling) and displays the vehicle's position along a 1/4 mile track segment. After testing a configuration, users can save a ghost recording for future performance comparisons with other setups.

Configurable vehicle parameters include:

- Maximum Power

- Power curve (definable point by point)

- Torque curve (automatically derived from the power curve since power = torque × RPM)

- Maximum engine RPM (ignition cutoff)

- Gear configuration (up to 10 gears)

- Resistance coefficients (Cx, frontal area, and rolling resistance)

- Vehicle weight

- Tire size

- Shift time

- Transmission efficiency

Calculated performance parameters include:

- Top speed

- Acceleration times (0-60, 0-100, 0-200, 0-300, etc.)

- Any additional metrics measurable through the interactive simulator
