Jenner} _______ Rm{William Robotham - Chief Engineer}8/R.15.6.39. ENGINE CAPACITY & TAX. Attached is a summary of the tax which our projected engines will have to pay. It is somewhat of a shock to note that the 4-cylinder engine which we have been contemplating as being an economy unit is taxed at the rate of no less than £25 per year. We are positive that if we are to sell any volume of cars made from the set of rationalised parts which we have developed we shall have to have six 4-cyl. engines available in the range. It will be observed that counting insurance the Ripple is likely to have to pay £15 more per year than the 4-cylinder unit. Additionally, of course, the fewer pieces in the 4-cylinder will save Factory cost. Rm.{William Robotham - Chief Engineer} | ||
