The Cadillac Eldorado convertible was the last American convertible amidst safety regulations in 1976, marking the end of domestic convertibles until the return in the 1980s.
Safety regulations, rather than government mandates, led to the demise of convertibles as automakers faced challenges in redesigning vehicles to meet new requirements.
The National Traffic and Motor Vehicle Safety Act of 1966 and subsequent regulations like roof strength proved detrimental to the production of convertibles.
In a 1971 meeting with President Nixon, automaker executives raised concerns about the financial burdens posed by proposed safety regulations like passive restraints.
The proposed passive restraint regulation, which included airbags or thick dash padding, was ultimately dropped in the 1970s due to affordability concerns.
The focus on safety regulations shifted the automotive industry towards alternative designs like targa bars and removable roof panels instead of traditional convertibles.
The declining popularity of convertibles was also influenced by advancements in air conditioning and the introduction of sunroofs as alternatives for open-air driving.
From 1982 to 2005, domestic and imported convertibles made a comeback in the market with models like the Chrysler LeBaron, Mercedes-Benz SL, and BMW Z3.
The modern limited availability of domestic convertibles, such as the Ford Mustang and Chevy Corvette, reflects consumers' shifting preferences towards SUVs over convertibles.
Overall, consumer demand, changing preferences, and evolving safety regulations have played significant roles in shaping the history and decline of the American convertible.
