| W/S - Cx.{Major Len W. Cox - Advertising Manager} x200 Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}16/KW.20.12.35. Replying to your Cx.{Major Len W. Cox - Advertising Manager}11/KW.25.11.35. Herewith are the acceleration curves. We do think that acceleration curves are very dangerous because it is possible to cheat so tremendously. For instance, the Terraplane figures given in the "Autocar" were done with a car of the "Orange-box" type; i.e., no wings and a racing body. If we took Hall's Bentley we should get the same result. The figures we give are honest average figures. We are standardising the 6.4/1 compression ratio. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
