Terms used to describe early the evolution of design

When the first motor cars appeared, little atten-tion was paid to their appearance; it was enoughthat they ran. Consequently the cars initially sold to the public mostly resembled horse-drawn car-riages with engines added. Henry Ford launchedhis Model T in 1908, and it sold on its low priceand utility rather than its looks. However, thebody design of this car had to be changed overits 19 year production span to reflect changes incustomer taste.
 The 1930s saw greater emphasis on stream-lining design. Manufacturers began to use windtunnels to eliminate unnecessary drag-inducingprojections from their cars. One of the dominantstyling features of the 1950s and 1960s was thetail fin, inspired by the twin tail fins of thewartime Lockhead Lightning fighter aircraft.Eventually a reaction set in against such excessesand the trend returned to more streamlined
 styling.
 In creating cars for today’s highly competitive car market, designers have to do far more than justachieve a pleasing shape. National legal require-ments determine the positions of lamps, directionindicators and other safety-related items, whilethe buying market has become much more sophisti-cated than before. Fuel economy, comfort, functionand versatility are now extremely important.
