x1265 W/P - Sr. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}8/KW.6.4.36. Re Phantom III Petrol Consumption. Replying to Sr./Dn.9/MLG.31.3.36. We anticipate that the Ph.III will do between 8 and 9 m.p.g. when driven at average speeds of 40 m.p.h. and over under English conditions. It may be less on flat out "blinds" on the Continent, unless a higher axle ratio is fitted for these conditions. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
