X7120 W/S. To Cx.{Major Len W. Cox - Advertising Manager} from Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson} c. to WOR.{Arthur Wormald - General Works Manager} c. to EP.{G. Eric Platford - Chief Quality Engineer} Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson}5/KT.3.7.33. Mr.Sears - 31-GX. With reference to Cx{Major Len W. Cox - Advertising Manager}5/KW27.6.33. We have to agree with Mr.Sears that the latest continental Phantom with the high geared axle and body 3 cwts. heavier than 31-GX will have inferior acceleration. Mr. Sears' figures are obviously incorrect because we have never approached the time of 6.3/5 secs. from 10-30 m.p.h. on the continental Phantom in top gear, but the fact remains that generally speaking he is right. For anyone who is primarily interested in acceleration, there is no reason why the continental car should not be fitted with a lower axle ratio, which will at once make a 10% improvement in the pick up. There is no doubt that the continental Phantom has grown considerably since the original model 26-EX, and it is interesting to have evidence that customers appreciate the results of such a small weight increase on performance. The next 10,000 miles Phantom will have an 8 litre. engine fitted, but the resultant increase in acceleration will only be equivalent to reducing the complete car weight by 2 1/2 cwt.
