X 7779 We foresee that in twelve months time the present 25 HP. car and the present Continental P.II will have to have an improved performance in order to maintain their position and sales. We know that twelve months is a very short time in which to produce anything new. 25 HP. There is no prospect of making any material improvement in the present 25 HP. car. The Kemsport car represents the very best we know at present that can be done with that engine. The improvement in the 25 HP. therefore lies in the introduction of J.III. The position of J.III is on the whole satisfactory but there is a lot of detail work necessary to bring this up to date and to incorporate the improvements found necessary on peregrine. We are busy preparing a specification for J.III making certain that it incorporates all the necessary modifications. The chief advantage in J.III over the present 25 HP. will be increased performance, lower chassis, better body space, and should be reduced cost. P.II Continental. The introduction of Kemsport will demand a better performance from the P.II car especially taking into account the difference in price. Although we may be satisfied at the moment with the Continental P.II we must by next year have an improved model. As we all know the difference between the standard P.II and Continental P.II is very small. In fact, it almost amounts to the length of the chassis and the style of the coachwork. We want to strongly recommend that we adopt a new policy with the Continental P.II. We boast at the present time that our Phantom car will carry a 4 1/2 ton. armoured car and stand up to it without giving any trouble. We consider this very that contains the car as being suitable for a high performance. We can't expect a car to carry round this weight of chassis to carry a light body and four people. Our proposal is that we take our patent Phantom engine with the larger bore and fit it into J.III chassis. We have put together a mock-up so that we know it can be done without much difficulty. It is a similar job to fitting | ||
