caption_attribution_description: English: This is an all-transistor car radio, that was developed by GM's Delco Radio (Model 7268085) for the 1957 Cadillac Eldorado Brougham car models. It used 13 transistors and was available as a standard feature, only on the limited production 1957 Cadillac Eldorado Brougham car models.
context_page_description: The Cadillac Motor Car Division is a division of the American automobile manufacturer General Motors Company that designs and builds luxury vehicles. Its major markets are the United States, Canada, and China. Cadillac models are distributed in 34 additional markets worldwide. Cadillac automobiles are at the top of the luxury field within the United States. In 2019, Cadillac sold 390,458 vehicles worldwide, a record for the brand.
  Cadillac is among the first automobile brands in the world, second in the United States only to fellow GM marque Buick. The firm was founded from the remnants of the Henry Ford Company in 1902. It was named after Antoine de la Mothe Cadillac, who founded Detroit, Michigan. The Cadillac crest is based on his coat of arms.
  By the time General Motors purchased the company in 1909, Cadillac had already established itself as one of America's premier luxury car makers. The complete interchangeability of its precision parts had allowed it to lay the foundation for the modern mass production of automobiles. It was at the forefront of technological advances, introducing full electrical systems, the clashless manual transmission and the steel roof.
context_section_description: Postwar Cadillac vehicles innovated many of the styling features that came to be synonymous with the late 1940s and 1950s American automobile. Incorporating many of the ideas of then General Motors styling chief Harley J. Earl, these included tailfins, wraparound windshields, and extensive use of chrome. Tailfins were first added in 1948 and reached their pinnacle in 1959. From 1960 to 1964 they decreased each year until they disappeared in the 1965 model year (remaining vestigialy only on the limited production 1965 Series 75 chassis, a carry-over from 1964). Cadillac's other distinctive styling attribute was its front-bumper. What had started out after the war as a pair of artillery shell-shaped bumper guards moved higher on the front-end design as the 1950s wore on. Becoming known as Dagmar bumpers for their similarity to the buxom 1950s television personality, they were toned down in 1958 and gone the next year.
  1956 saw the introduction of the pillarless four-door hardtop sedan, marketed as the "Sedan de Ville"; a year later the feature appeared in all standard Cadillacs. The fledgling automotive magazine Motor Trend awarded its first "Motor Trend Car of the Year" to Cadillac in 1949 for its innovative overhead valve V8 engine. While the company initially snubbed the honor, it now proudly references its "Car of the Year" wins in publicity material. On 25 November 1949, Cadillac produced its one-millionth car, a 1950 Coupe de Ville. It also set a new sales mark of 100,000 cars, matched in 1950 and 1951. 1949 also saw the introduction with Buick of the first mass-produced hardtop coupe, a closed-body style without a "B" pillar. Marketed as the Coupe de Ville, it would become one of Cadillac's most popular models for many years.
  In 1951, Cadillac began production of the M41 Walker Bulldog army tank, which saw service in the Korean and Vietnam wars.
  In 1953, the "Autronic Eye" was introduced. This feature would automatically dim high-beam headlamps for the safety of oncoming motorists. In 1957, Cadillac attempted to move further upmarket, creating the hand-built Series 70 Eldorado Brougham. It featured self-levelling suspension, "memory seat" function, and an all-transistor signal-seeking car radio that was produced by GM's Delco Radio and which was available as standard equipment for the 1957 Eldorado Brougham models. While the car showed Cadillac's technological prowess, it sold only 904 units.
