| HS{Lord Ernest Hives - Chair} x206 To E.{Mr Elliott - Chief Engineer} from Sg.{Arthur F. Sidgreaves - MD} Copy to Hs.{Lord Ernest Hives - Chair}Worr. BY.{R.W. Bailey - Chief Engineer} Efficiency of Brakes on RR and Bentley Cars. If you have not already done so, I should be glad if you would study the Road Test Performances given in 'The Motor' this week on Page 265. You will see that in comparison with other cars the 3 1/2-litre Bentley and RR 20/25 show up badly. For instance - 3 1/2-litre Bentley 82% from 30 m.p.h. 76% " 50 m.p.h. Rolls-Royce 20/25 80% " 30 m.p.h. 75% " 50 m.p.h. A study of the others will show - 3 1/2-litre Alvis 90% from 30 m.p.h. 82% " 50 m.p.h. 3 1/2-litre Hotchkiss 100% " 30 m.p.h. 95% " 50 m.p.h. 4 1/2-litre Lagonda 96% " 30 m.p.h. 84% " 50 m.p.h. Railton 100% " 20 m.p.h. 89% " 40 m.p.h. 14 h.p. Rover 98% from 20 m.p.h. 92% " 40 m.p.h. 17 h.p. Armstrong 95% " 30 m.p.h. 90% " 50 m.p.h. 12 h.p. Flying Standard 98% " 30 m.p.h. 88% " 40 m.p.h. I should be glad to hear from you after you have studied the matter. Sg.{Arthur F. Sidgreaves - MD} | ||
