MotorSim 2: Precision Performance Calculator for Land Vehicles
Advanced Physics-Based Simulation Engine for Automotive Engineering & Tuning

🛠️ Core Features – Full Vehicle Dynamics Modeling

MotorSim 2 delivers high-fidelity, real-world physics simulation grounded in classical mechanics, thermodynamics, and fluid dynamics. All calculations are based on measurable engineering principles, not approximations.

🔧 1. Engine Modeling (High-Resolution Power/Torque Curves)

• Input: Peak horsepower (HP) and torque (Nm), with full curve definition via user-defined RPM points (up to 20 data points)
• Advanced Features:
  • Polynomial interpolation between user-defined torque/power points
  • Inclusion of engine inertia and rotational mass effects
  • Realistic torque rise and fall characteristics
  • Redline RPM with power falloff modeling beyond peak
• Output: Instantaneous horsepower and torque at every RPM in real time

⚙️ 2. Drivetrain & Transmission Configuration

• Gearbox Settings:
  • Up to 10 selectable gears (manual or automatic)
  • User-defined gear ratios (including final drive and differential)
  • Optional: Launch control settings (torque management, clutch slip control)
• Shift Dynamics:
  • Adjustable shift duration (0.1–2.0 seconds)
  • Clutch engagement profiles (soft/standard/sport)
  • Gear-lag and inertia delay simulation
• Efficiency Modeling:
  • Transmission losses (mechanical efficiency: 92%–98% adjustable per gear)
  • Differential losses (including limited-slip torque bias ratio)

🚗 3. Vehicle Dynamics & Aerodynamics

• Mass & Inertia:
  • Total curb weight (kg): 800–4000 kg (adjustable by component)
  • Center of mass height and longitudinal bias
  • Rotational inertia (flywheel, wheels, driveshaft)
• Aerodynamics:
  • Drag coefficient (Cx): 0.25–1.0 (e.g., Formula 1 to SUV)
  • Frontal area (m²): 1.5–4.0
  • Downforce modeling (optional: lift coefficient vs. speed)
• Tire & Rolling Resistance:
  • Tire size (e.g., 245/35R19)
  • Rolling resistance coefficient (Crr): 0.01–0.025
  • Tire slip and grip modeling (μ-slip curve with temperature-dependent friction)
• Braking System:
  • Brake bias distribution (front/rear)
  • Thermal fade modeling (optional)

  • Starting line (burnout paddle, line lock)
  • Timer (0.000s precision)
  • Ghost car overlay (compare up to 5 saved builds)
  • Surface type (asphalt, concrete, racing slicks)

📁 Save & Compare – Engineering Workflow Integration

• Save configurations as .motorsim files (encrypted, version-controlled)
• Compare multiple builds side-by-side:
  • Side-by-side ET and trap speed
  • Graphical overlay of acceleration curves
  • Delta analysis (performance gain/loss per modification)
