| -2- RUSSELL./H.R.CLARK. [Strikethrough] from the "plaking" they are all using considerably higher compression ratios than we are, but there is no sign of increased engine roughness. Their silent thirds are good and when a higher direct drive ratio is incorporated with them as on the GRAHAM PAIGE the absence of fuss, increase in smoothness, good fuel consumption etc. at once becomes noticeable after the prevailing low gear fashion. We think that the GRAHAM PAIGE car is particularly worthy of attention as having the best 6 cylinder engine we have tried, and an exceptionally silent third with a reasonably easy change from 2nd. to 3rd. and 3rd. to top. The Weymann body undoubtedly contributed to the good impression. The other features on the cars, steering, brakes, clutches, and suspension, show little improvement in design during the last few years and are undoubtedly inferior to our own practice. 116/2a. | ||
