MORE POWER.
One of the most important developments in automobile engine design of recent years has been the - stepping- up of the revolutions per minute. less than twenty years ago, the 4-cylinder power units, even in racing ears, ran at about 2">00 r.p.m.; to-day racing engine speeds of 5000 to 6000 r.p.m. are not uncommon, whilst even passenger cars nowadays often touch between 3000 and 4000 revolutions. The object of this increase in engine speed is to obtain more power with the same cylinder displacement.
