MotorSim 2

A performance calculator for land vehicles.

MotorSim 2 is a performance calculator for land vehicles. Please note: this is not a driving game. It performs a physical simulation of a vehicle's acceleration in a straight line.

MotorSim 2 lets you configure technical specifications and calculates the resulting performance. It features an interactive simulator with a speedometer, RPM meter, throttle, brake, and gear shift (manual or automatic), complete with a procedurally generated engine sound and a visual representation of the vehicle on a 1/4 mile track. After testing a setup, you can save a ghost car to later compare its performance against other configurations.

Configurable vehicle parameters include:

- Maximum Power

- Power curve (definable point by point).

- Torque curve (automatically defined from the power curve, as power = torque * RPM).

- Maximum engine RPM (ignition cutoff).

- Gearbox configuration (up to 10 gears).

- Resistances (drag coefficient, frontal area, and rolling resistance).

- Vehicle weight.

- Tire size.

- Shift time.

- Transmission efficiency.

Calculated performance metrics are:

- Top speed.

- Acceleration times: 0-60, 0-100, 0-200, 0-300, etc.

- Plus any other metric you can measure using the interactive simulator.
