Some Important Problems Concerning the Small Utility Car

Abstract

This survey on the small utility car is based on the work performed under the supervision of the lecturer as Director of the Design and Engineering Division at S.p.A. Fiat in Italy. The lecture deals with the general principles relating to the design of a small utility car, mass-produced at the rate of at least 350 per day, particularly suitable for the Italian market, but also of technical and commercial interest to other European countries.

Taking as his example a four-seater car having a weight ranging from 500 to 600 kg. (1,100 to 1,320 lb.) and with a total piston displacement of from 400 to 600 cc. (24 to 37 cu. in.), the lecturer analyses the most important factors that influence weight and therefore cost, such as general car architecture, dimensions, performance and quality.

Some of the problems peculiar to rear-engine installation, which required a larger amount of studies and research during the design and layout work for the Fiat ‘600’ car are then examined.

According to the lecturer, the rear-engined car represents the best solution both in regard to smaller outer dimensions required for given passenger accommodation, and as to constructional simplicity. The lecture is concluded with a forecast of future developments in this type of car.
