Aerodynamics

Coming in v2. Will expose drag and downforce sensitivities, aero-CoP sweeps, and a side-by-side run between aero-on and aero-off. Intended for teams running wing packages who want to trade drag for cornering grip across specific track sectors.

Powertrain

Coming in v2. Will allow the active torque map to be swapped and compared, expose gear ratio sensitivity runs, and show where on the power curve the solver spends most of the lap. Useful for gearbox and engine tuning decisions.

Energy Management

Coming in v2. Will show how power limits and lift-and-coast strategies affect lap time and energy consumption together. Targets teams subject to the FS energy rule and wanting to find the fastest lap within an energy budget.

Validation

Coming in v2. Will let a team load a logged lap from a real event and compare it channel by channel against a simulated lap on the same track. The goal is to quantify model error and build confidence before using the sim to make setup decisions.
