X3317 CWB. has obtained one of these cars for us for a week, through the courtesy of General Motors. Our impressions of the car are :- ENGINE : Quite smooth and free from periods up to the master vibration (43 m.p.h. on 2nd.). On the master period it emits a noise like a machine gun, possibly due to a peculiarity of the Summers Harmonic Balancer. Responds instantly to the accelerator like the Star Stutz. There is a propeller shaft period about 53 m.p.h. but not very severe. STEERING. Very low geared, light and free from shocks. Apparently a lot of the gearing down is done in the steering box because it is almost totally irreversible. This results, as it always does in our experience, in poor high speed selectivity. SUSPENSION. Lovejoy dampers all round. The riding is not so good as that of the 20 HP., there is too little damping at high speeds. BRAKES. These are much improved since the earlier varieties on these models, they are still but moderately efficient however. External contracting brakes are retained on the front wheels. The steering is unaffected presumably because there is little front braking. contd :- | ||
