MotorSim 2: Your Land Vehicle Performance Calculator

MotorSim 2 is a powerful performance calculator for land vehicles. Unlike driving games, it focuses solely on the physics of straight-line acceleration. The app lets you define vehicle specifications and then calculates the resulting performance characteristics.

An interactive simulator provides real-time feedback, including a speedometer, tachometer, throttle, brake, and manual or automatic gear shifting. The engine sound is procedurally generated, not sampled, and the simulation visually tracks vehicle position along a 1/4-mile track. Saved simulations ("ghosts") allow for easy comparison of different vehicle setups.

Configurable Parameters:

• Maximum Power
• Power Curve (point-by-point definition)
• Torque Curve (derived from power curve)
• Maximum Engine RPM
• Gear Configuration (up to 10 gears)
• Drag Coefficient (Cx), Frontal Area, and Rolling Resistance
• Vehicle Weight
• Tire Size
• Shift Time
• Transmission Efficiency

Calculated Performance Parameters:

• Maximum Speed
• Acceleration times (0-60 mph, 0-100 km/h, 0-200 km/h, 0-300 km/h, etc.)
• A wide range of other performance metrics measurable within the interactive simulator.
