MotorSim 2

MotorSim 2 is a specialized performance calculator designed for land vehicles. Please note that this application is not a driving game—it is a physics-based simulation tool focused on analyzing vehicle performance during straight-line acceleration.

With MotorSim 2, users can configure various technical parameters and simulate the resulting performance. The app features an interactive simulator complete with a speedometer, tachometer, throttle control, brake, and manual or automatic gear shifting. Additionally, it generates realistic engine sounds procedurally (not through audio samples) and visually represents the vehicle's progress along a simulated 1/4 mile track. Once a configuration has been tested, users have the option to save a ghost or shadow vehicle, allowing for direct performance comparisons between different setups.

Configurable Vehicle Parameters:

• Maximum Power Output
• Power Curve – Adjustable point-by-point for precise tuning
• Torque Curve – Automatically calculated based on the defined power curve ([ttpp]since power = torque × RPM[yyxx])
• Maximum Engine RPM – Set ignition cutoff limits
• Gear Configuration – Supports up to 10 gears
• Aerodynamic and Rolling Resistance Values – Including drag coefficient (Cx), frontal area, and rolling resistance coefficient
• Vehicle Weight
• Tire Dimensions
• Shift Time – Adjustable for realism
• Transmission Efficiency

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 Simulator Readings – Offers real-time data tracking for any measurable performance aspect

MotorSim 2 is ideal for automotive enthusiasts, engineering students, and performance tuners looking to experiment with virtual vehicle dynamics without leaving the garage.
