MotorSim 2

MotorSim 2 is an advanced performance calculator designed specifically for land vehicles, offering a detailed physical simulation of their straight-line acceleration performance. It's important to note that MotorSim 2 is not a driving game; rather, it's a tool for enthusiasts and engineers to analyze vehicle dynamics without the need for real-world testing.

With MotorSim 2, users can input and configure a wide array of technical specifications, allowing for a tailored analysis of vehicle performance. The app includes an interactive simulator that features a speedometer, rpm meter, throttle, brake, and gear shift options (both manual and automatic). To enhance the user experience, the app generates engine sounds procedurally, rather than using sampled audio, and provides a visual representation of the vehicle's progress over a 1/4 mile track segment. Users can save a performance run as a ghost or shadow, enabling future comparisons with different settings to assess improvements or changes in performance.

The configurable vehicle parameters in MotorSim 2 include:

• Max Power
• Power curve, which can be defined point by point
• Torque curve, automatically defined based on the power curve, since power equals torque multiplied by rpm
• Max engine RPM, including ignition cutoff
• Gears configuration, with support for up to 10 gears
• Resistances, such as Cx (drag coefficient), frontal area, and rolling resistance coefficients
• Vehicle weight
• Tyre size
• Shift time
• Transmission efficiency

Based on these inputs, MotorSim 2 calculates a comprehensive set of performance metrics, including:

• Maximum speed
• Acceleration times from 0-60 mph, 0-100 mph, 0-200 mph, 0-300 mph, and beyond
• Any other performance metrics that can be measured using the interactive simulator

MotorSim 2 stands out as an invaluable tool for those looking to delve deep into the performance analysis of land vehicles, offering a rich set of features that cater to both casual enthusiasts and professional engineers alike.
