| -6- X in front, we urge that this method be gone into without delay. [strikethrough]List of such applications follows.[/strikethrough] Q 3. Any other ways in which you think improvement can be effected in the suspension of our cars. A MISCELLANEOUS. Q 1. What in your opinion are the features which should be improved on the 40/50 ? State them in what in your opinion is their order of relative importance. A 1. Performance. 2. Springing (damping methods) 3. (Flexible coupling. (Silent second gear, with easy change. 4. Brakes, much simpler adjustment. 5. ( Preventing of over-heating in front compartment. ( Clutch design and maintenance. The present ( single-unit system appears to have prevented ( reasonable accessibility and consequent ( low cost of repairs and attention. 6. Steering. 7. Water-cooling, radiator and matrix design, effort to improve cooling should be continuous. 8. Silence. 9. Control of head-lamp dipping to be on steering-wheel, now common practice. 10. Reliable ignition-coils, so that the sparking plug gaps can be set from point of view of slow-running. Q. 2. Noise. What are the most prominent and objectionable noises in the present car (exhaust, carburetter intake, mechanical etc.) in their relative order of importance. 1. Popping in exhaust. 2. Carburetter intake fuss and roar. 3. Noisy second-gear. | ||
