| -2- sufficient to allow enough front spring action. Front springs "bottom" far too easily and yet are not soft in action. The rear springs are fair at low speed but do not transmit to body any restful, floating movement until at least 40 miles per hour. High speed riding qualities of the car are infinitely better than low speed. Experimental work with springing, already started at Springfield, should be continued and progress until a satisfactory riding condition over the range of speeds has been accomplished. 3. PERFORMANCE. The performance of the car is excellent when considering alone the size of the car and the engine. However, when consideration is given to total weight, namely, 3825 pounds, it is apparent that this factor, namely weight, more than any other one, is responsible for the general result. The general result, however, is what the American public accepts or rejects and unfortunately the appeal of the car will not be enhanced by intelligent consideration of the fine engineering employed to build a car of this size of such light weight. We must therefore, from the practical standpoint, view the performance of the car from a comparative one, with that of other American cars with which it will compete. In the writer's opinion, the car is below the standard set by the following cars in acceleration, hill-climbing at various speeds and maximum speed:- | ||
