MotorSim

MotorSim is a drag racing and performance simulator for cars and motorbikes (please note that this app is not a driving game, as it only does a physical simulation of their performance as the crow flies).

MotorSim allows you to configure a number of vehicle parameters to calculate what the resulting performance will be. It includes an interactive simulator with speedometer, rpm meter, throttle, brake and gear shift (manual or auto), with procedurally generated engine sound (not by sampling) an a representation of vehicle position over a 1/4 mile road segment. Once a setting has been tested, the user can save a ghost/shadow in order to later compare this setting performance with some other.

Configurable vehicle parameters are:

- Power curve (can be defined point by point).

- Torque curve (as power = torque * rpm , defining the power curve automatically defines the torque one).

- RPM for gear shifting (used for auto mode).

- Max engine RPM (ignition cutoff).

- Gears configuration (up to 9 gears).

- Resistances (Cx, frontal area and rolling resistance coefficients).

- Total vehicle weight (including passengers).

- Tyre size.

- Shift time.

- Transmission efficiency.

Calculated performance parameters are:

- Maximum speed.

- Acceleration 0-60, 0-100, 0-200, 0-300,... and so on.

- ... and any other you can measure by using the interactive simulator.
