| To Hs.{Lord Ernest Hives - Chair} from BJ. Copy to By.{R.W. Bailey - Chief Engineer} BJ2/H16.11.25. X8350 'NEW PHANTOMCodename for PHANTOM I' BACK AXLE RATIO. Please let us know what experiments have been made and conclusions arrived at in regard to 14-tooth axles on the New PhantomCodename for PHANTOM I. We are meeting customers who are disappointed with the acceleration and hill-climbing of New PhantomCodename for PHANTOM Is with heavy closed bodies. In the past we understand there has been some difficulty with 14-tooth axles in two respects: (1) making them silent; (2) when the car reaches high speed and high revolutions, the power falls off rather too early. In the event of our finding customers who we feel fairly confident will not expect to go at very high speeds, but will greatly appreciate acceleration and hill-climbing, we might like to give them 14-tooth axles. We should like to have your views on the subject first, please. B.J. | ||
