Maximum tractive force
The total tire force (F_{t}), at a given speed v, can be found if the power available at the tires (P_{t}) is known:

(1) 
Converting engine power to wheel power (more)
Top speed
From equation (1) and equation (1b) from the accelerating page, we get: (more)

(2) 
Where:


And:
ρ  = atmospheric air density (= 1.225 kg/m³) 
C_{D}A  = Drag factor 
C_{L}A  = Lift factor 
m  = vehicle mass 
g  = gravitational acceleration (= 9.80665 m/s²) 
f_{r}  = rolling resistance coefficient 
*Note: If we neglect rolling resistance (f_{r} = 0) then we can simplify to
.
v_{max}=
