| -2- Rm{William Robotham - Chief Engineer}/FAS.10/HH.14.3.40. With regard to the effect of streamlining on fuel economy, we estimate that given the same tyres and frontal areas the Corniche requires 4 H.P. less than a standard Bentley V to propel it at 50 M.P.H., and 6 H.P. less at 60 M.P.H. This also means 20 H.P. at 90 M.P.H. Rm{William Robotham - Chief Engineer}/FAS. | ||
