MotorSim 2

Performance Calculator for Land Vehicles

MotorSim 2 is a powerful performance calculator designed specifically for land vehicles. Please note that this application is not a driving game, but rather a physics-based simulation tool focused on vehicle acceleration performance in a straight line.

With MotorSim 2, users can configure a wide range of technical specifications and instantly observe the resulting performance metrics. The app features an advanced interactive simulator complete with a speedometer, RPM meter, throttle control, brake input, and both manual and automatic gear shift options. Additionally, it generates realistic engine sounds procedurally (not through audio sampling) and visually represents the vehicle's movement along a 1/4 mile track segment. After testing a specific setup, users have the ability to save a ghost or shadow of that run, allowing for direct performance comparisons between different configurations at any time.

Configurable Vehicle Parameters:

• Max Power
• Power Curve – Fully customizable point-by-point editing
• Torque Curve – Automatically calculated based on the defined power curve (since power = torque × RPM)
• Max Engine RPM – Set ignition cutoff limits
• Gear Configuration – Supports up to 10 gears
• Aerodynamic and Resistance Values – Adjustable Cx (drag coefficient), frontal area, and rolling resistance coefficients
• Vehicle Weight – Total mass input
• Tyre Size – Diameter and width adjustments
• Shift Time – Define how quickly gears change
• Transmission Efficiency – Adjust drivetrain losses

Calculated Performance Metrics:

• Top Speed
• Acceleration Times – Including 0–60 mph, 0–100 km/h, 0–200 km/h, 0–300 km/h, and beyond
• Interactive Measurements – Any additional data that can be observed using the real-time simulator interface

Whether you're tuning virtual cars, preparing for drag racing, or simply curious about vehicle dynamics, MotorSim 2 provides a highly accurate and immersive way to explore and compare automotive performance characteristics.
