MotorSim 2: Vehicle Performance Calculator
MotorSim 2 is an advanced performance calculation tool for land vehicles (note: this is not a driving game, but rather a physics-based simulator focused on straight-line acceleration analysis).
Core Features
The application enables detailed configuration of technical specifications and computes resulting performance metrics. Key components include:
- Interactive simulation interface featuring:
- Speedometer and RPM gauge
- Throttle and brake controls
- Manual/Automatic transmission selector
- Procedurally generated engine sound (algorithmically created, not sampled)
- Visual representation of vehicle position on a 1/4 mile track
- Ghost car functionality to save and compare different configuration performances
Configurable Parameters
Users can adjust numerous vehicle specifications:
- Powertrain:
- Maximum power output
- Customizable power curve (point-by-point adjustment)
- Torque curve (automatically derived from power curve)
- Maximum engine RPM (ignition cutoff)
- Transmission:
- Gear configuration (supports up to 10 gears)
- Shift times
- Transmission efficiency
- Vehicle Dynamics:
- Aerodynamic resistance (drag coefficient)
- Frontal area
- Rolling resistance coefficients
- Curb weight
- Tire dimensions
Performance Calculations
The simulator provides comprehensive acceleration metrics including:
- Top speed estimation
- Standard acceleration times (0-60, 0-100, 0-200, etc.)
- User-definable acceleration benchmarks
All calculations are based on precise physics simulation, allowing users to test configuration changes and compare performance results directly within the application.
