THE RUNABOUT BODY 
T -^hree Stages of Motor Development 
In the first stage, higher power was obtained by building larger 
cylinders. In the second stage, greater flexibility was secured by 
adding cylinders. Both involve serious handicaps in a reciprocating 
engine. In the third stage, upon which gas engine design is now entering, a 
higher range of inherent capability has been developed—more power from 
existing plant. Simple and rugged, the sixteen-valve four draws straight 
from the source of high power and flexible performance: valve efficiency.
