On the road our impression was that the nett result of providing lateral control, (the car was driven fast round corners without any objectionable rolling) has been to spoil the suspension at low speeds, and even at high speeds, it is defin- itely inferior in the back seats to the rear of the Lancia. The brakes are quite effective. The only impressive demonstrat- ion the driver was able to put up was to mount a high curb with the N.S. wheels: under these circumstances the behaviour of the car was remarkably good. 10-HP Ansaldo. This car, which is the latest product of the firm has a transverse front leaf spring attached to the centre of the chassis by a trunnion bearing. The support for the trunnion bearing is carried to the rear of the gearbox as in the sketch. The whole chassis is therefore 3-point suspended. The axle control is provided by a torque arm as in the Ford, Austin-7 and others. No shock absorbers were fitted. The lateral stability is obtained by a very wide frame at the rear and two semi elliptic as near XX contd :- | ||
