Vehicle Speed V Calculating

V = n/itot x UA x 0.06
- n = Engine speed (RPM)
- itot = Overall ratio
- UA = Dynamic role circumference of tires (m)
- V = Vehicle speed (km/h)

Example:
- V = 1000/3.440 x 1.93 x 0.06 = 34 km/h

At an engine speed of 1000 RPM, the vehicle road speed in 5th gear is 34 km/h.
