Disclaimer: This is an excerpt from my dissertation. I love cars so much I spent a year researching and writing 11,000 words, despite professors telling me it wouldn’t be considered a “legitimate” academic subject. Then, I bought a 1952 Chevrolet pickup as my daily driver.
Even as late as 1959, many industry insiders thought that the trend of be-chromed and be-winged automobiles would continue into the future, evolving in an ever-more exaggerated fashion- after all, inferring from sales data, it would certainly seem as though that style was popular. There were indications of an approaching change, though: a switch in design leadership within two of the Big Three, a rapidly increasing share of the market taken up by foreign imports, a changing youth culture (influenced by European tastes and the emerging counter-culture) dictating a larger segment of the auto-buying demographic, and a public fed-up with paying too much for a form-over-function product. Smaller external factors helped contribute to the styling shift and downsize as well, such as domestic manufacturers, looking to reclaim lost European markets, adapting their cars for a more global taste.
The role car designers played in the styling shift is a little complicated. For both Chrysler and GM, looking at their model lineups before and after Virgil Exner and Harley Earl left each respective company shows a clear separation in style. And, interviews and biographies indicated that their replacements, respectively Elwood Engel and Bill Mitchell, favored sharper edges and simpler designs than their forebears. It is also important to note that the roles of Mitchell and Engel in the styling shift at their companies were not singular; this styling shift did not spring from the minds of trend-setting car designers alone. Ford’s styling team remained the same throughout the styling shift, and this points to something larger: Engel was one of the most important designers on their team, and he replaced Exner at Chrysler after Ford had already released their fresh, crisp 1960 models. So, Engel helped bring Chrysler the style of the 1960s, and Bill Mitchell helped GM with the same, but for Ford, the impetus to revise their design standards came from elsewhere.
In no small part were automakers pressured into this style change by the general consuming public. Throughout the second half of the 1950s, European imports bit into an increasingly larger share of the US market. These cars were smaller, better-engineered, and more simply styled than their American counterparts- the impression this gave to consumers was that these foreign companies were spending money on the actual functionality of the product rather than its appearance; an honest business practice. Compounding the problem of the popularity of European cars was the declining reputation of domestic manufacturers. The Big Three were being lambasted by buyers for selling poorly-assembled machines which grew more expensive each successive year for no apparent reason: one of few tangible “benefits” to the increasing cost were design revisions that often reduced functionality.
Not only was Europe delivering a superior automobile to the American masses, they were also emerging as global taste-makers in music, art, and culture. Britain, especially, was a leader in this department, and American youth were particularly receptive to the trends coming from across the Atlantic. In each place, somewhat simultaneously, a consumer protection movement gained traction, designed to discourage corporations from pursuing the types of dishonest practices favored by the Big Three. Some of the philosophy behind this movement- the focus on integrity, authenticity, and honesty- would meld into a burgeoning counter culture with a youthful epicenter. Many high-profile figures from both the USA and Europe, including musicians who were enormously influential among baby boomer, were proponents of this counterculture, and used their autos to make statements surrounding it, shining a spotlight on the car.
The baby boomer generation was reaching driving age around the year 1960- and their parents- unprecedented prosperity afforded them a considerable amount of disposable income. Both of these factors, coupled with the sheer size of the youth population, pressured automakers to cater to the baby boomer demographic. Further, because products with the perceived quality of youthfulness were so fashionable, the tastes of the youth fast-became the tastes of the public. The Big Three had no choice but to adapt to the changing conditions, and began producing cars that appeared more similar to the honestly-styled, practicality-minded European models. After all, that type of machine appealed more to youth than the chrome-encrusted status-symbols of yesterday.
Finally, the period immediately following World War II was one of extreme excess for the US auto industry. Manufacturers rabidly increased the size, power, price, and bright work on their cars without necessarily making them perform any better or more reliably. While the newly-built US interstate system could cope with the land yachts emerging from Detroit, the medieval streets of Europe were simply too narrow for many to seriously consider purchasing an American product. This lead to a declining share of the market abroad for the Big Three- these once-had, now-potential sales provided even more incentive for them to produce smaller and more sensible machines. And, gradually, subsequent to the release of the compact trio in 1960, the ground lost was being reclaimed.
This styling shift is an odd one. The vast majority of every car produced and sold in the United States exhibited similar styling- rounded, bulbous shapes adorned with chrome, tailfins, bubbly windshields, and gaping grilles- and, besides a few murmurs in 1959, everything seemed to be going business-as-usual. But over the next few years (ending for the most part in 1964), the entire US car industry, still in tandem, headed in the opposite direction. Round, amorphous shapes were muscled into cleanly-sculpted surfaces with definition, creases, and sharp edges. Chrome was stripped away, grilles shrunk, and once-distinct elements became cohesive as the manufacturers strived to design a product with perceived integrity and honesty. The influences governing this shift were myriad, but they resulted in the car, once more, reflecting the values and mood of American society.
