Vehicle Speed V, Calculating

Vehicle Speed V, Calculating

V = n: IOVX UAX 0.06
N = Engine speed (RPM)
IOV = Overall ratio
UA = Dynamic rolling circumference of tires (m)
V = Vehicle speed (km/h)

Example:

V = 1000: 3.100 x 1.93 x = 37 km/h 0.06
At an engine speed of 1000 RPM, the vehicle road speed in 5th gear is 37 km/h.
