MotorSim 2 is an advanced performance calculator designed specifically for land vehicles. It's important to note that this app is not a driving game; rather, it focuses on simulating the physical performance of vehicles during straight-line acceleration.

With MotorSim 2, users have the ability to configure various technical characteristics of their vehicles and analyze the resulting performance. The app features an interactive simulator that includes a speedometer, RPM meter, throttle, brake, and gear shift options (either manual or automatic). Additionally, it generates engine sounds procedurally, rather than using samples, and displays the vehicle's position along a 1/4 mile track segment. After testing a particular configuration, users can save a "ghost" or "shadow" of the performance to compare it against other settings later on.

The following vehicle parameters can be configured in MotorSim 2:

• Max Power
• Power curve (which can be defined point by point)
• Torque curve (since power equals torque multiplied by RPM, defining the power curve automatically defines the torque curve)
• Max engine RPM (ignition cutoff)
• Gears configuration (up to 10 gears)
• Resistances (Cx, frontal area, and rolling resistance coefficients)
• Vehicle weight
• Tyre size
• Shift time
• Transmission efficiency

The app calculates the following performance parameters:

• Maximum speed
• Acceleration times from 0-60, 0-100, 0-200, 0-300, and beyond
• Any other performance metrics that can be measured using the interactive simulator
