This redistribution of load, caused by acceleration, is an argument against the adoption of front-wheel drive, for, in this case, instead of the weight on the driving axle increasing when the machine is accelerating, it decreases. Once a vehicle is moving, its own acceleration redistributes the load, so that the weight on the rear axle is increased and further tendency to lose grip on the road is obviated. It is a well-known fact that, in some of the more powerful private cars, it is possible for the tractive effort at the rear wheels to overcome road adhesion when the machine is started rapidly from rest and so cause the wheels momentarily to spin. This is particularly true of braking efficiency, but it also has its effect on other aspects, such as acceleration, steering and riding comfort. THE disposition of weight, both laden and Unladen, on the front and rear wheels of any vehicle has a definite effect on the all-round performance of the machine.
