| III Cars with 9" deflection seem just about - as uncontrollable as the standard Car with 4 1/2" deflection, both being arranged to give the optimum boulevard ride. We shall certainly require ride control to get high speed cornering & stability. Packards. I was very impressed with Packards, as previously mentioned I consider their engine to be the smoothest & most silent 12 cyl I have tried (160 B.H.P. 445 cu ins dish), their suspension as good as any conventional and their gearbox remarkably silent. I also drove their light eight / 320 cu ins which is quite a nice automobile, refined and well sprung at about £500. It is not as well silenced intake & exhaust as the Buick. Packards are playing a lone hand doing little or no aircraft work at present nor are they in any way mass producing. Their testing is most thorough, their standard for a major alteration being 50,000 miles. They have just completed a 10,000 miles run on the 12 cyl continuous full throttle full speed without trouble. | ||
