Calculation Formula

V_max = sqrt( (2 * P) / (m * Cd * A) )

Where:
V_max = Maximum Velocity (m/s)
P = Engine Power (HP)
m = Vehicle Weight (kg)
Cd = Drag Coefficient
A = Frontal Area (m²)

How to Use the Calculator

  1. Enter the engine power of your vehicle in horsepower (HP).
  2. Input the weight of your vehicle in kilograms (kg).
  3. Provide the drag coefficient (Cd) of your vehicle. This value typically ranges from 0.3 to 0.5 for most cars.
  4. Enter the frontal area (A) of your vehicle in square meters (m²). This can usually be found in your vehicle's technical specifications.
  5. Click the "Calculate" button to compute the theoretical maximum velocity.
  6. The results will be displayed in meters per second (m/s) and kilometers per hour (km/h).

Understanding the Formula

The calculator uses the following formula to estimate the maximum velocity:

V_max = sqrt( (2 * P) / (m * Cd * A) )

Where:

  • V_max is the maximum velocity in meters per second (m/s).
  • P is the engine power in watts (W), converted from horsepower (HP) by multiplying by 745.7.
  • m is the vehicle weight in kilograms (kg).
  • Cd is the drag coefficient, a dimensionless quantity that depends on the vehicle's shape.
  • A is the frontal area in square meters (m²).

This calculation provides an estimate of the maximum velocity a vehicle could theoretically achieve under ideal conditions. Actual performance may vary due to factors such as aerodynamic efficiency, tire grip, and other real-world conditions.
