R-R car with body of same type..............49 cwt. 2 qrs. do. 20/25 h.p. R-R car with body of same type..............37 cwt. 1 qr. do. (b) Body Weights. Cadillac...................Approx. 19 cwt. 40/50 h.p. car of same type (R-R). " 14 cwt. 20/25 h.p. R-R car of same type " 11 cwt. (c) The accessories on the Cadillac weight about 1 1/2 cwt. On an R-R car of the same type they usually weight about 2 qrs. 15 lbs. 2. CHASSIS. The design of the Cadillac chassis makes for exceptional rigidity of the main frame or body platform, whilst its suspension system is such that the body is well insulated from road shocks. In addition, the brakes are comparatively poor so that the body cannot be subjected to the severe stressess set up by harsh braking. Again, the road springs can be damped to a limited extent only so that it is not in the power of the driver to interfere seriously with the insulation of the body from road shocks. 3. CHASSIS FRAME. The main frame is 8.250" deep and has a cruciform section 7.250" deep of considerable length. The result is an extremely rigid frame. | ||
