It is hoped that this paper will give U. S. engineers a general picture of the probable developments in European small car performances in the next decade. No effort has been made to deal with the technical problems involved in the development of low drag bodies, only to demonstrate developments in form hold the key to obtaining improved performance in European type cars without encroaching on cost or running charges which have been, and will continue to be, the determining factor in sales.
To summarize, economic factors prescribe that normal European cars should not exceed 2,000 lb. all-up weight, and should be capable of at least 30 m.p.g. in day to day running. Improved body form will permit such cars to sustain road speeds of 70-80 m.p.h., and this will make the small economy car increasingly competitive with larger types. This competition will be fortified by world developments in motor roads which will mask the inherent limitations of the small car in the aspects of hill climbing and acceleration.
