On slippery roads, vehicle reactions are clearly more intense, as shown in the figure. The dynamic oversteer of the investigated RWD vehicle caused by overlapping lateral and longitudinal tire forces results in the vehicle spinning into the initial curve.
The advantages of the distribution of the traction forces between four wheels in the case of AWD become obvious on a slippery road. On a dry road however, the differences are related more to the steady-state steering behavior (minor understeer tendency) than to the drive concept.
