Summary:

In specialist literature it has been determined that the fuelconsumption of cars travelling at high speed is less withfour-wheel drive than with conventional drive via only oneaxle.The question is whether a previously unused potential savingalso exists here for heavy commercial vehicles. By means ofsystematic consumption measurements under various operatingconditions with precise monitoring of the parameters, the fuelconsumption differentials of the axle arrangements 4 X 2, 4 X 4,and 6 X 4 are determined. Simultaneously, the effect on thespeed/torque collective of the drive engine measured during thesetest runs is shown. The results show the same tendency both for thesolo vehicle with a low slip load on the drive axle and for thetractor vehicle of a heavy long-distance tractor/trailercombination, while quantitative differences of course exist: thelosses due to additional power transmission elements (transfercase) outweigh the gain as a result of the lower tractive load onthe drive wheels.Furthermore, the test arrangement is described, with which theload collectives are measured and recorded in a form suitable forcomputer evaluation. Here great value has been placed on thepossibility of using the method universally for differentapplications
