Bailey - Chief Engineer} 25HP. FOR FRANCE. From this car, and my J.{Mr Johnson W.M.} 1., one learnt the following: (1) A car with a high C.G. - i.e. weight in the roof and windows, glass screen, etc - cannot have such flexible springs as a car with lower C.G., such as my J.1. The effect of the high C.G. is most marked in bad steering, and E, says sea-sickness. (2) I do not agree with flexible springing if the car is to be driven fast, as in testing in France. After 80MPH. 'China' with this body had poor acceleration, due to the power falling off, great windage, and weight, - i.e. compared with my J.1. R.{Sir Henry Royce} | ||
