In the ‘80s, cars were predominantly boxy, but within just a few years, they evolved into sleek, curvy designs. This transformation is not only about aesthetics but reflects the powerful influence of European trends, fuel economy regulations, and technological advancements. Discover the surprising story behind this shift and how it reshaped the automotive industry in the blink of an eye!

Why Cars Went From Boxy in the ‘80s to Curvy in the ‘90s

If you look at a photo of a street scene from the ‘70s or early ‘80s, a lot of things may appear surprisingly familiar to what we see today. The buildings are mostly similar, and people’s clothes, while slightly different in terms of style (think shoulder pads), aren’t drastically dissimilar. But there’s one noticeable difference: all the cars are notably boxy, especially when compared to the sleek, curvaceous designs of virtually every modern car on the market today.

This transformation—often overlooked—is probably the most distinct design change cars have undergone over the last 50 years. For most American cars, this shift occurred within a span of just a few years, beginning in 1986. Some models even show a sharp contrast year over year, such as the Buick LeSabre, which had sharp, angular edges on its hood, roof, and trunk in 1991 (left) but became noticeably smoother and curvier in 1992 (right).

What caused such a dramatic shift? It turns out, it was largely driven by three interconnected factors: European design trends, government-mandated fuel economy regulations, and technological advancements that made it easier for manufacturers to create curved shapes.

European Luxury Designs: The Initial Inspiration

By the 1980s, designing cars with curves wasn’t a brand-new concept—it had just gone out of favor with American automakers. Streamlined models from the 1930s, such as the Chrysler Airflow, had a sleek, aerodynamic design intended to minimize wind resistance. However, these models, including the Airflow, were commercial failures, outpaced by the larger, boxier cars preferred by the American market.

Meanwhile, in Europe, where fuel prices were always higher, designers, particularly in Germany, had been exploring aerodynamic designs much earlier. Luxury car manufacturers like Porsche, BMW, Audi, and Mercedes-Benz were among the first to bring back curved exteriors in the 1960s and 1970s.

One of the earliest and most iconic examples was the Porsche 911, which debuted in 1963 and featured a curvaceous design well ahead of its time.

Curves Arrive in the U.S.: Ford Leads the Way

By the mid-1980s, American automakers began to imitate European aerodynamic aesthetics. Ford, more than any other company, played a pivotal role in bringing these curved designs to the mass market. The 1982 Ford Sierra, released in Europe, featured a much more curvy design compared to other cars of its era. Initially, the car received mixed reviews (with the design even nicknamed the “jelly mold”), but over time, consumers grew accustomed to the style.

In the U.S., Ford designer Jack Telnack, who had previously worked on the company’s European design team, was directly responsible for the shift toward curves. His 1983 Ford Thunderbird was heavily influenced by wind tunnel testing, which emphasized aerodynamic lines. The design’s success culminated with the release of the 1986 Ford Taurus, which marked the beginning of a new era for American car design.

Fuel Economy and Government Mandates

Another key reason why curved designs spread so quickly and have remained popular is simple physics. Curved exteriors and steeper windshields reduce wind resistance, allowing air to flow more easily over the car. This means less fuel is needed to move the car the same distance at the same speed.

When the Ford Taurus debuted, automakers were also dealing with Corporate Average Fuel Economy (CAFE) standards for the first time. Beginning in 1978, manufacturers were required to meet increasingly stringent fuel economy targets for their passenger car fleets sold in the U.S., with a plateau at 27.5 miles per gallon by 1990.

While automakers had already made some improvements in fuel efficiency through engine upgrades and other components, the new curved designs made it far easier and cheaper to achieve further gains. According to historian David Gartman, one Ford designer claimed that increasing fuel efficiency by a mere tenth of a mile per gallon through engine upgrades would cost $200 to $300 million, whereas aerodynamic design could achieve a three- to four-tenths increase at almost no additional cost.

Automakers started relying more heavily on wind tunnels and aerodynamic calculations during the design process, and engineers worked more closely with designers. Within just a few years, nearly every car on the market began to resemble the once-futuristic Ford Taurus. As automotive author Larry Edsall points out, “They all looked the same because they were all being shaped in the wind tunnel, and were designed for fuel economy.”

Technology Made Curves Easier to Produce

Key technological advancements also played a crucial role in making these designs possible—and allowed automakers to make their cars even curvier over time.

For decades, car models were created using clay, wood, and other physical materials. In the 1980s, however, designers began to use computer models to create car designs. “It’s much easier to make these sorts of shapes with computer drawings rather than wood,” says Penny Sparke, author of A Century of Car Design. “The new methods gave automakers the means to produce those very soft curves.”

Manufacturing technology also made it easier and more affordable to produce curved shapes in aluminum, further accelerating the shift toward curvier cars.

As a result, since the initial shift in the 1990s, car exteriors have only continued to become curvier. You can get a good sense of how profound this change has been by looking at a car that is still considered relatively boxy by modern standards: the 2008 Scion xB. While its boxy hatchback stands out, the edges are far more rounded than the truly boxy cars of the ‘80s, including the groundbreaking 1986 Ford Taurus.

Conclusion

The shift from boxy, angular designs in the ‘80s to curvier, sleeker cars in the ‘90s was driven by several key factors, including the influence of European luxury designs, government regulations pushing for better fuel efficiency, and advancements in technology that made creating curved shapes easier and cheaper. While the designs of today’s cars might not mirror the classic European sports cars, the influence of curves and aerodynamics is still a dominant force in car design.
