MotorSim 2

MotorSim 2 is a specialized tool designed for enthusiasts and engineers looking to analyze the performance of land vehicles through detailed simulations. This app is not your typical driving game; instead, it focuses on providing a comprehensive physical simulation of vehicle performance during straight-line acceleration. By allowing users to input and configure various technical specifications, MotorSim 2 offers an in-depth look into how these settings impact a vehicle's performance.

With MotorSim 2, users can customize a wide array of vehicle parameters to see how each affects acceleration and speed. You can set the maximum power, define the power curve point by point, which automatically calculates the torque curve since power equals torque multiplied by RPM. Other configurable settings include the maximum engine RPM where the ignition cuts off, gear configurations with up to 10 gears, resistances such as drag coefficient (Cx), frontal area, and rolling resistance coefficients, vehicle weight, tyre size, shift time, and transmission efficiency. This level of detail ensures that users can simulate real-world scenarios with precision.

The app features an interactive simulator equipped with a speedometer, RPM meter, throttle, brake, and options for manual or automatic gear shifting. It also generates engine sounds procedurally, rather than using sampled audio, adding to the realism of the simulation. Additionally, the simulator displays the vehicle's position over a 1/4 mile track segment, allowing users to visualize their vehicle's performance in a tangible way. After testing a configuration, users can save a ghost or shadow of the run, enabling them to compare different settings later on.

MotorSim 2 calculates several key performance metrics based on the user-defined parameters. These include the maximum speed achievable, acceleration times from 0 to various speeds such as 60, 100, 200, 300 mph, and beyond. Users can also measure any other performance data using the interactive simulator, making MotorSim 2 a versatile tool for anyone interested in the dynamics of land vehicle performance.
