MotorSim 2 – Land Vehicle Performance Calculator
  

    Not a driving game — a physics-based simulation for precise straight-line acceleration analysis.
  

  

    
Key Features
    

      
Interactive Dashboard: Real-time speedometer, tachometer, throttle/brake controls.
      
Transmission Simulation: Fully configurable manual or automatic gear shifting (up to 10 forward gears).
      
Procedural Engine Sound: Dynamically generated audio based on RPM and load — no pre-recorded samples.
      
Quarter-Mile Visualization: Track-based simulation with vehicle position tracking and performance overlay.
      
Ghost Car Mode: Compare multiple configurations side-by-side using time-travel simulation.
    
  

  

    
Configurable Vehicle Parameters
    

      
Peak Power Output: Set maximum horsepower or kilowatts.
      
Custom Power Curve: Define user-specified RPM-power data points for realistic modeling.
      
Derived Torque Curve: Automatically calculated from power curve and RPM.
      
Redline & RPM Limiter: Set engine rev limit with realistic torque falloff behavior.
      
Transmission Setup: Customize gear ratios, shift points, and shift duration (0–200ms).
      
Aerodynamics: Input drag coefficient (Cd), frontal area (m²), and wind resistance.
      
Rolling Resistance: Adjustable coefficients for different tire/road types.
      
Vehicle Mass: Define curb weight, driver load, and dynamic mass distribution.
      
Wheel & Tire Dimensions: Select size, aspect ratio, and rotational inertia.
      
Drivetrain Efficiency: Account for losses in transmission, differential, and driveline.
    
  

  

    
Performance Metrics & Analysis
    

      
Theoretical Top Speed: Computed using power, aerodynamics, and drivetrain limits.
      
Acceleration Times: 0–60 km/h, 0–100 km/h, 0–200 km/h, and custom intervals.
      
Quarter-Mile Results: Elapsed time (ET) and trap speed at finish line.
      
Real-Time Data Logging: Monitor acceleration, g-forces, wheel slip, and engine load.
      
Force & Torque Distribution: Analyze drive wheel torque and traction limits.
      
Optimization Feedback: Suggestions for performance gains based on parameter sensitivity.
