MotorSim 2

MotorSim 2 is an advanced performance calculator tailored specifically for land vehicles. This app, distinct from driving games, focuses on conducting physical simulations to evaluate vehicle performance during straight-line acceleration. By allowing users to input and adjust various technical specifications, MotorSim 2 provides an in-depth analysis of how these settings influence overall performance.

The app features an interactive simulator equipped with essential tools such as a speedometer, RPM meter, throttle, brake, and gear shift options (both manual and automatic). Users can also experience procedurally generated engine sounds, not reliant on sampling, enhancing the realism of the simulation. Additionally, the app offers a visual representation of the vehicle's progress over a standard 1/4 mile track segment. After testing a configuration, users have the ability to save a ghost or shadow run, facilitating later comparisons with different settings to gauge performance variations.

MotorSim 2 enables users to configure a range of vehicle parameters, including:

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

From these inputs, MotorSim 2 calculates critical 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

By offering a comprehensive toolset for analyzing and comparing vehicle performance, MotorSim 2 serves as an invaluable resource for enthusiasts and professionals alike who are keen on optimizing their land vehicle's performance.
